not sure if anyone here has one. my brother in law is 14 and is a beginning racer. his dad is not swift when it comes to knowing what to buy or how to install anything. not a mechanic.
i'm not up to snuff on these. not to many sites with info on the web. and of course everyone that does porting does the best.
like to get some more info on who does porting on these and what exhausts are available other than the obvious ones.
its an mx bike and this winter may get some engine work.
so if anyone has some info or knows where i could get it, i sure would appreciate it.
Full Version: crf150r.............. anyone got info or experience???
he raced it this past summer. i was thinking that tearing it down for a piston would be the first step. je makes a nice 12.5:1 for it. not wanting to make the jump to race fuel as of yet. add a stage 2 cam while in there, and add a pipe. needs jetted severly. they come way off from the factory. wont idle unless set very high. turn it down and it dies.
did some research and found that a jd jet kit will cure it. change the pilot, and comes with parts to do a accelerator pump mod that works real well.
the suspension is gonna get a little tweaking as well.
just wanted to find some places to soak up some knowledge on these for the down the road work.

give me a call if you like, I've built plenty of these. I have custom cams for these and I do flow bench porting also. you can run more than 12.5:1 on pump with these no problem. I have pistons too. Thanks, Tony (Yves Edge Performance 520-904-0678)
awesome.
not sure how involved he and his parents want to get into racing. not sure they realize how much time and effort is going to be necessary.
hopefully they feel like spending some cash on this bike. sure would be a lot of fun to tinker with.
just picked up a pro circuit t-4 on ebay. brand new for 175.
thanks for the info. if it gets that involved, i will definately be in touch.

My little brother has one. We had F C mods do the suspension. Put a piston and cam in it and its a whole differnt machine now. I even take it out to the track to toy around on sometimes. There fun little bikes.
