Sep 4, 2020 · a stock KX100 is set up for about a 100lbs rider. With the quite stiffer fork and shock springs required for a 160lbs rider, you will also need the forks/shock revalved to match as you won't be able to compensate for their extra stored energy with the rebound clickers alone.

Feb 7, 2021 · Thought I'd start a thread documenting my mods for a KX100 play bike. I have full size bikes, but I wanted a smaller bike to ride with my young kids as they grow up. Big bikes don't ride slow enough. 4 Stroke "trail" bikes are pigs with garbage suspension. I thought this would be fun to play with. 2009 KX100 Monster Energy edition.

Nov 23, 2020 · You can build a KX100 engine into a rocket but versus even a stock 125 it will always have the disadvantage of smaller wheels and less suspension travel. HP is only one part of the 'package', putting the power to the ground and having the bike handle are more important factors in the overall package.

Dec 9, 2020 · Long time stalker of the forum but I'm a noob Dad and stuck. Lost spark on my son's KX100. It's a 2007 so I figured I'd just redo all of it just to be safe because of its age. Stator, ignition coil, CDI. I still don't have spark. Metering the new electrosport stator, it …

Apr 7, 2017 · Hey Kawi riders! Wondering what upgrades I can do to a new KX100 will give me better performance for woods riding. I would also like to know if upgrading the exhaust/muffler actually increases overall hp instead of just transferring the powerband a bit. The 2014+ models already have 28hp. Hard to...

Nov 16, 2022 · The brake caliper assembly on the kx100 forks has been retained as well as hose and master cylinder. Surprisingly everything in the wheel/brake/fork assembly, kx100 forks and brake caliper, klx wheel+brake disc and spacers fit together perfectly. Swept braking area may be less, will measure. Kx100 fender and number plate fit up nicely as well

Dec 18, 2020 · I purchased a kx100 at a fair price because the previous owner stated it had low compression. I hooked up my compression tester and it makes 170psi after 6 to 8 or so kicks. To me this doesn't indicate low compression. It's a long test hose so I think 6 to 8 kicks is fair. it IS running poorly, like the carb is messed up, and tons of spooge.

Feb 5, 2022 · I want to change my oil on a 2019 kx100, but dont know exactly what to use. i heard 10w-40 is good. and one more thing for 2 stroke transmission oil, if it says 4 stroke is it still good to use on a 2 stroke transmission oil?

Sep 7, 2017 · I just purchased a 2018 KX85 and KX100 to replace our older ones for my daughter who races on a regular basis. I am installing a FMF fatty pipe and a FMF power core II exhaust on it. I want to get the optimal performance out of it so should I rejet it and put aftermarket reeds in it or leave the current jets and reeds in. I am running a 32:1 ...

Jan 27, 2009 · I am seeking your collective wisdom in my fight to get more linear power delivery from a KX 100. In the ongoing struggle to make a KX100's power delivery more similar to a CRF 100's power delivery, I am considering adding a homemade spacer to the exhaust to try to increase the header length.
