LT-Z50 4 Stroke

The CT Sonic pipe adds torque which allows the LT-Z50 to pull off of the corners and accelerate up little hills much harder. The CDI box is still needed to be able to climb larger hills and to obtain some more speed. What we found is that the LT-Z50 has a very low rev limit (5000) that keeps the speed down and the only way to get around it is a new CDI box. The Dyna FS CDI box moves the rev limit up to just over 8000 RPMs and with the flick of a switch, unlimited revs. We now have the Dyna FS CDI box in stock for $259.95. You can gain some speed by pulling a washer out of the front clutch. This allows the belt to shift out farther, gaining speed. You can find instructions for doing this in your owner’s manual (please don’t call us for these instructions).

We also now have an LT-Z50 clutch mod kit. Our kit moves the stall speed up to where the motor is making power before engaging the clutch. We also change the weight of the rollers to keep it in the power band as the belt shifts. With the clutch engaging at about 4500 RPMs, the motor pulls much harder from a standing start and can take off in softer terrain and on steeper upgrades.  The kit is relatively simple to install. You can do it yourself with basic tools. The kit includes new high output lightweight rollers, 3 sets of springs in different tensions to allow various stall speeds, and two larger main jets.

Below is a link to CT Racing future sponsored rider, “Wild Man Woody”, testing his CT kitted LT-Z50 4 stroke. Woody is a professional, so don’t let your kids attempt these stunts. Look for Woody to dominate the World Championships in 2020. This is a great little video if you want to see how the LT-Z50 kit performs. Woody’s kit does not have the new clutch kit installed.

LT-A50 2 Stroke

Suzuki’s two-stroke Quad Sport LT50 was around for quite a few years. Kawasaki even borrowed the model for a couple years, re breeding it as the KFX 50. It was the nearly  perfect learning machine for the smallest of ATV enthusiasts. Unfortunately, its power output was so meager, that by the time  riders began mastering the very basics, they had outgrown the engine’s power.Dave and Holly Trimble wanted to get their daughter, India, into ATV racing. The size of the KFX50 fit her perfectly; however, the Trimbles were afraid that the little two- stroke didn’t have enough pep to pull her up the faces of some of the taller jumps at Earlywine Indoor Motocross in Maysville, KY where they race.

CT tried different clutch setups to complTo help his daughter get around the track, Dave installed CT Racing engine package for the LT and KFX 50 on India’s machine. He sent his head to CT for modification and it came back with a CT pipe, jet kit, and a K&N filter with Outerwear pre-filter. The most impressive looking part of the kit is the CT pipe. While the stock pipe looks like something off a four- stroke, the chrome finish CT exhaust features a tuned expansion chamber and a large aluminum spark arrested silencer. It’s too bad you can’t appreciate the exhaust’s appearance under the ATV’s bodywork. Installation of the entire kit took just over an hourement the package, but found the performance of the stock clutch to work best. According to their dyno, the stock engine puts out only 1.2 horsepower, peaking out at around 3600 RPMs. With CT’s engine kit installed, the engine is said to produce 2.6 horsepower peaking around 6700RPMs, more then doubling the stock power output.

The Test

With the CT motor package installed it was off to the races. The little KFX now emitted a nice two- stroke sound without being too loud or raspy. Power delivery was still very smooth and controllable, although the engine pulls stronger throughout the RPM range, revving out way further. The KFX now had the power to easily pull India around the track. Steep jump faces were easily conquered, even if she didn’t approach the jumps with much momentum. This kit would also make it much easier for the youngest rider in the family to keep up on trail rides.

India had a lot of fun on her CT Racing hopped- up 50 and had the trophies to prove it. Her dad thought it looked like so much fun he hijacked the machine for the pit bike class and was surprised that it could even pull him up the jumps, as long as he kept his momentum up.

For $679.95 CT’s kit greatly enhanced the engine’s performance compared to stock. Our young test rider will remain entertained much longer with this hopped micro-machine, allowing some time to grow into a larger ATV. Both factors make CT’s LT and KFX 50 engine package a must have hop-up for these micro-sized machines.LTA50 2 STROKE lt 50 / lt-z 50 performance parts LT 50 / LT-Z 50 LTA50 2 STROKEThe dyno chart above shows the stock LT-A50 horsepower in blue.
