14 tooth

[riverz]

Anyone using a 14 tooth sprocket? What are your thoughts on the extra bottom end? I'm looking for more bottom end rather than zip for the areas I ride. I really can't afford an expensive pipe right now...Saving for a new KDX in the fall.

I have an 03 kdx 200 and the only mods i have done are take the air box lid off and go to a 12 tooth and wow this bike went from a slug to an amazing bike, It has great low end along with zip when you want it!

yup, if you want more low end you need to drop a tooth rather than go up one... I switched to a 12 tooth on my '01... I barely ever clutch even in the tightest of singletrack

i run stock gearing on my 91 kdx.. i put a wiseco prolite piston in it, boysen pro series reeds, and removed the airbox lid. theres a very noticeable increase from stock power over the whole range with those mods and all together it cost just a little over $200

but the 12 tooth front sproket is $9.99 at Dennis Kirk (RT Sprokets I think)

The airbox mod is free (and advisable).... jetting costs about $20 (for all the jets you might need.... again, from DK)..

for $29.99 you can pull a lot more low end out of that machine.... (not that those more expensive options listed aren't good too)

smaller front sprocket=lower gearing.larger rear sprocket=lower gearing. i run 12/49 on the stock 108 link chain. tons more torque...almost like a 4stroke. you will lose top speed,run through the gear quicker,have to shift more. 12/49 is great for tight woods trails or real muddy conditions.under ordinary conditions you can start in second gear. i go to 13/49 for the wide open spaces, on the same chain.

I was running stock with a pipe and jetting and ran in a steep up and down gran prix race and really needed lower gearing so I put on a 50t rear that I had. Helped signifiantly but I still waste some of top gear so I'm adding a 12t front to see how that is.
