well i go to the track with my stock crf100 and it just isnt powerful enough to keep upwith the other bikes its a practice track, and it needs help like making a turn into a jump the second im out the turn i down shift but it takes a while to get that power going i want quick responce, power and speed can only spend about 250 300 bucks


THANKS-COORTSO

so you have to realize that it's a 100f...it's not a track bike...it's a trail/fun bike. to really get significant power gains would require endine modifications (big bore kit, cam, pipe, etc.) even then it's not going to be able to hang with 2-stroke 80 and 100cc bikes. those will typically have up to twice the hp and are lighter than the 100f.

i wish i had better news for you. perhaps others have a different view.

well, CRFs gave about the best answer i could think of but, the 100F is NOT track material. although it will do very well in tight spots. you should try flattracking. here they have a class for smaller 4 strokes. if you want a race bike you should get the: CR85, KX100, KTM105, RM85, KX85, KTM85, YZ85... these will all give you the power you need and will be much faster.

Yeah the 4 stroke will never catch up with a 2 stroke ive tryed it with my 80 and a CR80 the CR was at the finish line and i was only half way down(my bike is bored out has big gun exhaust system has new carb and is a supermoto bike and still couldnt catch up)

Hey dirtbikeboi1234, can u post some pics of ur bike if you have any. You said its supermotoed out. I'd like 2 c it Thanks

[dirtbikeboi1234]

[dirtbikeboi1234]

o yea i sold the exhaust an the carb also sry i didnt have any pics either

[spyke999]

It kinda sounds like you really didn't have the supermoto/engine mods ever? Not trying to start a flame here but that's whats on my mind.

what i did was remove the spark arrestor and air filter screen for the spark arrestor u need to un bolt ur exhaust cap 3 bolts and chop off the screen and tube then for the air box u take the air filter off take the foam off look for a metal tab lift that up and off then rip off the screen then there is a mesh underneith that and im not sure if i should take it off i left it on and replaced the foam and put it back but if u want to rip the mesh off do it and tell me how it went bec im a noob in air boxes and intakes except for carbs i know a thing or 2 about carbs
