Could this be jetting???

[dfuhrig5]

I have an 08 WR250F and its been having some problems and I was wondering if this seems like a jetting issue to to you guys. So from 1/4 throttle to 1/2 throttle, sometimes up to 3/4 throttle it pulls like it should, but when you crack it open it doesnt pull al all. It pretty much just makes a lot of noise and doesnt go anywhere. Say Im on a hill, I have plenty of power up to about 3/4 throttle but if I twist anymore than that, it just doesnt pull and I lose almost all momentum. The bike doesnt backfire, pop, or anything like that at all. I have had people suggest that it is the clutch or something going out. I am just really not sure at this point. So I figured that I would ask you guys for your opinion.
Thanks, Daniel

Yeah - it sounds like you could benefit from a larger main jet. I am giving a lot of merit to the newness of the bike, otherwise my internet diagnosis would likely be different. Given the bikes' likely good mechanincal condition jetting is a very likely probability.

That or a puked out air filter or possibly an out of spec float adjustment.

I put a 180 main in, thanks for all of your help. I also cleaned and re-oiled just to make sure there was proper amount of oil on it.
Thanks for the help!, Daniel
