WR450f 2004 starting problems after fitting FMF Q4

3 posts in this topic

Hi everyone,

I have just fitted a FMF Q4 to my 2004 WR450f and it started ok then i let it cut out...When i went to re-start the bike it will not fire up so i tried it without the choke and it still will not fire. When i had the standard pipe on it fired up first time??? Will i need to fit an FMF power-up kit?

The bike has standard jetting.....I went out today and it's starting ok now but when you warm it up and give it a quick rev it bogs a little......And as for uncorked? not sure what that is but what i can tell you is that i bought the bike from an old guy in mint condition with all the road stuff still on and it was not used much,
