Flywheel weight

<< < (2/3) > >>

Mike - where did you get the flywheel weight?  When you say carb spacer, did you mean between the carb and the motor, or a spacer in the carb to limit how much the slide can be opened?

thanks.kaos

Kaos,
  Steahly is one of the best. I doubt there is a choice of weights but what they sell is generally tested and pretty good.  Also the steahly is removable (it threads on like a flywheel cover in place of the retaining nut).  There was an old test on the net somewhere where they modified the KX100 for trail use by a girl. It was quite good if you can find it. The reed spacer is a 3/8" aluminum spacers that installs between the reed valve and the engine. It spaces the reeds away from the engine and gives more bottom end power. For taming the 100, the flywheel weight gets my vote for the most bang for the buck. Hope this helps. Cam.

kaos:
Thanks, Cam.  The spacer sounds like something I could build.  I remember helping out with something similar on a friend's small block chev motor many years ago, seems like the torque increase was noticable. 

I may have to build the FWW as well, as the Steahley and SFB sites don't show one for this bike.  I've sent emails to both companies tho, and I'll follow up this week with phone calls, on the off chance I can locate something.

This is becoming an interesting project.  I'd like to hear about any similar experiences, tips on how not to screw it up, that sort of stuff.

regards,
kaos

Stealhy Offroad have a flywheel weight for the KX 100. They actually have 3 as it comes in 12, 10 or 8 oz.

I put the 10 oz. stealhy flywheel weight on my 00 kx 100 and was very happy with the difference it made, it made the bike so much more rideable in the woods. The only drawback is a small loss in overall power. Great mod for the woods though. Hope that helps.  :-)
