Ok so i decided to put money into my wr. I go trail riding mostly and plan on training for enduro's and going to go and do barstow to vegas. So far i bought the bike from a guy who put a fmf q exhaust and pipe with some misc bolt on stuff, it isnt jeted properly right now main jet wise but runs great still.
What i want to do so far is a big bore to a 290 and a set of intake and exhaust hotcams stage 1. Also i plan to get a yz throttle stop. I need to know what jet sizes i need. Also ive heard contreversal views on the gray wire mod on the 2003 model, any views on it?
Finally what other mods should i get and need to make what i want work.
mods
I did all the "free" mods to mine, plus I put in a 290 kit, but it was also time to replace the valves ...... but the best mod was the suspension! I also got a 6.6 gallon tank (6.25 really) for those times when I need to be gone a bit. see my list of stuff i've done here http://sandslave.com/2003wr250f/
