Klx 125 Carburetor Adjustment? Top Answer Update

Kawasaki KLX125 (Suzuki DRZ125)

The KLX125 (Suzuki DRZ125) was sold by both Kawasaki and Suzuki for a number of years while they shared product lines. The only real difference was the color of the body. The Suzuki 125 engine is based on a long line of similar engines that have been used in various motorcycles and ATVs over the years. The LT125, LT160, LT185, LT230, DR100, DR125, DR185, DR200 and others all used some version of the same engine. The motor is a bit cumbersome, but that probably makes it more durable. While BBR has historically made a number of products for the DRZ-125, weak demand has resulted in many products being discontinued. Everything we currently sell is listed on our website.

At the time of its release, the Kawasaki 125 dirt bike was considered a formidable competitor in the 125 class. Its 1984 redesign marked the start of the KX™ range and restored credibility – a superb comeback for the Japanese manufacturer after a sluggish sales period in the ’70s and early ’80s. A high-performance dirt bike with a lot of promise, the KX 125 put Kawasaki back on the MX racing map.

The Kawasaki 125 Dirt Bike was a 124cc off-road bike manufactured by Kawasaki from 1974 to 2009. This seemingly straightforward enduro-style machine featured an all-new design that set the ball rolling for higher-displacement bikes that would eventually go on to win Baja championships.

Ingenuity has always been a key selling point for Kawasaki. And yet it was almost a decade before Team Green realized the same thing for the KX 125.

Luckily, it wasn’t too late and the bike’s 1984 overhaul kept it in the good graces of consumers and enthusiasts for another 25 years.

Read on and discover this and much more about the Kawasaki KX 125 in this article.

About the Kawasaki KX 125

The Kawasaki Dirt Bike 125 is a renaissance of the 1983 Quacker, known for its tremendous power but heavily criticized for its design flaws. During its construction, the Japanese manufacturer dispensed with the unwieldy chassis, hard forks, flimsy metal and nondescript design of its predecessor, retaining only two strengths – the front disc brake and the powerful engine. The KX 125 was then redesigned after Jeff Ward’s (former Kawasaki motorsport champion and IndyCar racer) factory machine.

One level higher

Key improvements to the Kawasaki 125 2Stroke are reflected in the frame, engine, transmission and overall reliability. The chassis has been configured with a shorter wheelbase and a steeper steering angle, providing a quicker response to steering inputs and improved handling when climbing.

Larger tubes in critical areas and reinforced gussets at the swingarm pivot made the new frame lighter but stronger. Team Green engineers strengthened the crankcases and increased the surface contact area to solve problems with air leaks.

Other updates included gears with wider teeth, new friction plates with embedded radial grooves for the clutch, internal ports, and an all-new expansion chamber and ignition. Of particular note were the improvements to the bike’s cooling system.

Compared to the previous year’s version, the 1984 KX received a longer single-sided radiator and increased water passages, eliminating overheating issues and delivering a 29% increase in cooling capacity.

As a result of these changes, the Kawasaki Dirt Bike 125 felt more like a 150cc machine, going from an MX bench warmer to a powerhouse. It pulled on the tracks earlier and did so with more authority than its equivalent displacement counterparts. The new motor also made the bike suitable for nouveau riders and not only for professionals.

That one handicap

While the KX 125 was considered the best in terms of performance and placement, its suspension system still screamed for improvement. Unfortunately, the tweaks made to the bike’s suspension components weren’t enough. The slightly stiffer springs still felt underdamped for intermediate to pro riders.

Due to large jumps that still ended in crash landings, and complaints of harsh mid-stroke spikes, the 1984 Kawasaki KX 125 was considered to have the worst front-end performance of any bike in the 125 class.

That’s not to say the inadequate suspension system was the only longstanding problem. The front disc brakes were still prone to leaks and required constant bleeding. Plastics continued to be prone to breakage, particularly on hard ridden or competition bikes – among others.

But while those aspects weren’t met, the Kawasaki 125 dirt bike was still a solid and reliable machine. His setbacks were not effective enough to prevent the bike’s rise to fame as the Ruler of the Roost.

Specifications and features of the Kawasaki 125 dirt bike

engine

The Kawasaki 125 Dirt Bike is powered by a liquid-cooled, 2-stroke, single-cylinder power plant with high-tech carbon fiber reed valves. It has a bore-to-stroke ratio of 54 × 54.5 mm (2.13 × 2.15 in). Engine displacement is 124 cm³ (7.6 cu in³) while the compression ratio is 10.6:1 (low speed)/8.1:1 (high speed). A 34mm Mikuni R-slide flat-bottom carburetor handles the air-fuel mixture. For later models, the carburetor size was upgraded to either a Keihin PWK36S or a Mikuni TMX38X.

The above engine configuration gives a Kawasaki 125 dirt bike a top speed of 55 – 60 mph (88 – 96 km/h), 26.5 Nm (2.7 kgf-m, 19.5 ft-lb) at 2,700 rpm max torque and 40.49 hp (29.6 kW) hp. Later versions fitted with the 38mm Mikuni carburetor achieved a top speed of 75 mph (120.7 km/h), 41.04 hp (30.6 kW) at 11,500 rpm and maximum torque of 27 Nm (2.75 kgf-m, 19.92 ft-lb) at 10,500 rpm.

Fuel & Lubrication

Fuel tank capacity is 8.2 L (2.2 US gallons) of unleaded gasoline with a minimum rating of PON 87/RON 91. Thanks to the KX 125’s engine configuration, the motorcycle offers a decent fuel economy of 60 mpg (3.92 L/ 100 km). . The manufacturer recommends fuel variants with < 5% MTBE (methyl tertiary butyl ether), < 10% ethanol or < 5% methanol. However, should the engine knock or ping, it is recommended to change the brand of fuel to avoid serious engine damage. 0.7 L (0.74 quart) of K-Tech 2-Cycle Oil or equivalent is also required. Recommended oil viscosity is SAE 10W-40 with a minimum API grade of SJ meeting JASO T903 MA, MA1, MA2 standards. Depending on the ambient temperature, you can opt for SAE 10W-30, 10W-50, 20W-40 or 20W-50. When using alternative lubrication on the KX 125, always refer to the owner's manual. If the viscosity is too high, it may otherwise run poorly or lose power at high speeds. powertrain A manual (wide ratio) 6-speed constant-engagement (left-foot operation) reverse-coil system and wet multi-plate clutch assembly deliver power to the wheels. A 520 O-ring chain (with 112 links + joint) regulates wheel spin. The Kawasaki 125 Dirt Bike's wide-ratio gearing is responsible for its ability to outperform the competition on the racetrack and produce massive power at lower revs, putting it on par with 250cc wheels. On '92-'93 models, the front and rear sprockets were changed from 13/51 teeth to 12/49 teeth (4.08), further improving acceleration. For reference, the stock gear ratios are below: Primary Reduction Ratio 3.200 (64/20) Final Reduction Ratio 3.923 (51/13) Gear Ratio (1st) 2.384 (31/13) Gear Ratio (2nd) 1.857 (26/14) Gear Ratio (3rd) 1.529 (26/17) Gear Ratio (4th) .) 1.294 (22/17) Gear Ratio (5th) 1.125 (27/24) Gear Ratio (6th) 1.000 (25/25) Overall Ratio 12.553 @ Top Gear ignition The 125cc Kawasaki KX has electronic CDI (Capacitor Discharge Ignition) and a primary kickstart system that wakes it up. The vehicle's entire charging system is a flywheel magneto, which also powers electronic accessories. Ignition timing is 13° BTDC at 9,710 rpm (initial “F” mark). All models feature a 130-CCA 12V (6Ah)/10 HR YTZ7 battery (view on Amazon) measuring 113 x 70 x 105 mm (4.44 x 2.74 x 4.12 in – L x W xH). They require an NGK BR9EIX spark plug with a gap of 0.7 – 0.8 mm (0.028 – 0.031 in) and a tightening torque of 27 Nm (2.8 kgf-m, 20 lb-ft) – except for the ' 97, which has an NGK BR9EVX connector. European versions have either an NGK R6918B-9 or NGK BR9ECMVX connector type. tires & brakes The front and rear aluminum wheels use Dunlop® tires. You can swap out the front tires for Maxxis M7304D Maxxcross Desert IT tires (check it out on Amazon). Likewise, the rear tires can be swapped out for Dunlop Geomax MX33 tires (see Amazon) - perfect for soft to moderate terrain. The recommended tire pressure depends on the track conditions - 80 kPa (0.8 kgf/cm², 11 psi) for muddy, sandy or slippery terrain and 100 kPa (1.0 kgf/cm², 14 psi) for rocky or hard surfaces. Proper pressure either increases the tread on the ground or helps prevent punctures or punctures. Finally, a 220mm (8.7") front disc with dual-piston calipers and a 200mm (7.9") rear disc provide stopping power and complete the KX 125's tire and wheel assembly. suspension The front suspension is a standard 43mm Kayaba fork (other model years have a shorter 36mm cartridge fork). The rear uses the same Uni-Trak® rear suspension used on the '83 125cc bike and the KLX 300, but slightly redesigned from its original configuration to offer less progression. The rear suspension was then paired with aluminum Kayaba shocks with a new bladder design (as opposed to the de Carbon system used by the Quacker), resulting in improved fade resistance, improved wheel travel and smoother handling. Both the front fork and rear shocks offer generous wheel travel – 300 mm (11.8 in) and 310 mm (12.2 in) respectively. They are also compression and air adjustable. However, they had no adjustment for rebound. Dimensions The overall dimensions of the Kawasaki 125 Dirt Bike are 2,155 x 825 x 1,200 mm (84.8 x 32.5 x 47.2 inches - L x W x H). Machines released in Europe differ only slightly in dimensions from those in North America – at 85.2 x 33.1 x 49.8 inches. Ground clearance is 340 mm (13.4 in) while the wheelbase measures 1,455 mm (57.3 in) ±2%. The saddle sits at a height of 930 - 940 mm (36.6 - 37 inches). Dry weight is 87 kg (192 lbs). Outside It has a tubular steel semi-double cradle frame (with 27.5° caster angle, 100 mm / 3.9 in. trail and 45° head angle). Standard parts on the Kawasaki 125 dirt bike include handlebars, grips, chain and fork guards, and front and rear fenders. Since the bike does not have a skid plate, purchasing a Devol skid plate (see it on Amazon) will help protect the underside of your vehicle. Styling-wise, Kawasaki carried over the polished look of Jeff Ward's Works Machine—everything except for the orange saddle, which was replaced with a more tasteful blue to match the bike's overall aesthetic. Apart from the colour, the seat has also been reshaped to have a contemporary design. This change complements the slimmer tank and fairing combo, making gliding forward less intrusive and easier. The buzzard-billed front fender became more rounded and had a thin alloy brace underneath that kept it from breaking when weighted down with mud. Kawasaki KX 125 price The KX 125's list price ranges from $4,949 to $5,099 for post-2000 models. However, resources for the MSRP of older KX versions can be a bit opaque. The data from Nada Guides only give average resale values ​​for all models up to 2005, omitting the last three years of production of the two-wheeler. Pre-1985 models hold their value fairly well, which is currently almost double the original list price. Conversely, later versions of the bike can cost as much as $250. Year - Fitment - Model Number Retail/Trade-in Value 1974 - 1977 Kawasaki KX125/A3 $690 - $7,095 1978 Kawasaki KX125-A4 $1,110 - $8,725 1979 Kawasaki KX125-A5 $750 - $7,375 1980 Kawasaki KX125-A6 1980 A7 $1982 $990 - $6,670 1982 - 1984 Kawasaki KX125-B1/B2/C1 $750 - $4,645 1985 - 1991 Kawasaki KX125-D1/E1/E2/F1/G1/H1/H2 $750 - $3,990 1992 - 1993 Kawasaki KX125J1 /J2 1,250 $ 1994 – 1998 Kawasaki KX125K1/K2/K3/K4/K5 $250 – $1,975 1999 – 2002 Kawasaki KX125L1/L2/L3/L4 $345 – $2,045 2003 Kawasaki KX125M1 $480 – $630 2004 Kawasaki KX125M2 $615 – $810 2005 Kawasaki KX125M3 $775 – $1,020 Online, the 125cc motorcycle's sellability seems to be overshadowed by the greater popularity of its successor, the Kawasaki KX250F. You can find this used classic in good condition by going to well-known dealer sites or direct to private owners. Expect used prices to fall in the same range as above. Anything over $4,000 would typically come with mods, lights, or performance-enhancing parts. From off-road to street legal While the Kawasaki 125 dirt bike is undeniably an off-road machine, consumers these days are buying the two-wheeler and turning it into a city ride. This should come as no surprise, as enduro-style bikes have recently become the go-to choice for both recreational and urban riding. This section explains how to convert your off-road bike into a daily commuter bike. DOT compliant headlight There are three characteristics that your headlight must meet: Have high and low beam function (and preferably operated via an easily accessible switch) Be clearly visible, but do not dazzle drivers or oncoming traffic Provide generous light distribution for day and night You can choose between halogen, HID or LED lights for your headlights. Note, however, that halogen lights put more stress on your bike's electrical system than LEDs. You also need a charging system for your battery. If you stick with halogen, make sure you get a new stator to power the lighting system you're fitting the bike with. Whichever you choose, I highly recommend using battery powered lights to avoid dimming the lights when the RPM is low. brake light & tail light Your brake/tail light should ideally be connected to a battery and stay on for at least 20 minutes. Its light should be visible enough to alert other drivers to slow down or draw attention when driving during the day. Only a single motorcycle brake light/tail light is required in certain states. To be sure, research your state/local government's guidelines on brakes and taillights. When installed correctly, the tail light will activate when both the rear brake pedal and front brake lever are pressed. A banjo bolt switch ensures that this is done by additional pressure in an activated brake line. Meanwhile, mechanical switch options work best for drum brakes. While you're at it, purchase an aftermarket bracket and fender combo for a finished look after installing the necessary lighting. rearview mirror Thankfully, mirrors go well with the dirt bike's rugged looks. While only some locations require a working mirror, it would make sense to install two. If you find stem mirrors in bad taste, you can opt for flat wide-angle mirrors or bar-end mirrors to improve the look. These options have a lower profile than most types while still doing a good job of eliminating blind spots on either side of your dirt bike. indicator Installing turn signals/turn signals may be skipped in some states/territories when using hand signals. But beware: self-cancelling turn signals are better because they allow you to concentrate on the road when turning. Refer to country-specific regulations when installing front and rear turn signals. Also observe the recommended height and the recommended distance between the indicators when mounting. DOT approved tires Fitting the KX with DOT-certified tires is a must, since the bike's stock rubber is poorly suited for pavement riding. Tires marked with the letters DOT on the sidewall, on the other hand, contain additional layers of rubber and are approved for highway speeds. Supermoto models are becoming increasingly popular as a way to convert an off-road vehicle into a dual-sport bike. And as long as sportbike tires fit your bike's rims, they can be swapped out for stock rubber. Horn – The two biggest requirements when installing a horn are as follows: It must be audible from at least 200 feet away It must be electric (some states reportedly allow non-electric horns to pass inspection) license plate holder Kits containing a replacement fender with license plate bracket and lighting are available online. Some options do not include a replacement fender. Regardless of whether you mount your license plate vertically or horizontally, a light is required to make the license plate clearly visible. Mounting an inexpensive LED strip above the license plate makes this possible. Other street-legal requirements include a muffler, reflectors, full digital instrumentation, a properly ventilated crankcase, and other EPA-friendly emissions controls. It may also be necessary to install a fan or tune the transmission for road use. Depending on the condition of your bike (if you have a used wheeler) you may need to do some suspension work, top end work and a frame restoration. The hardest part about getting your KX 125 on the road legally is getting the paperwork/permit from your local motor vehicle office.
