my quad is not runnng right
i have narrowed it down to a couple things
either the spark plug or other electrical componetns
or possibly the jetting but i think it is ecletrical
when it runs it will start rough and often stall
then acts like it wont warm up like a fowling plug you know you hit the gas and it kinda just stumbles
i had a blaster do this to me two times in the past and both times it was the cdi box
thats why i lean toward electrical
anyone else have this problem
only mod is i pulled out the baffle thats it ! cant afford much else

ifit ran fine before you pulled the baffle out either put it back in or rejet. this things come jeted stock pretty lean so it don't take much mods before you are in the extremely lean area. i wuld suggest you rejet regardless if you put the peashooter back in or not. just my .02

its simple rejet, and get a new plug, depending on what u mean by it stumbles off idle when u punch it. Thats normal all 450s do that.

Remeber K.I.S.S. (keep it simple stupid) always look at the easiest fix first. then your work your way into it. I'd check the plug first, then go on from there. If it's not the plug it'll be easy to tell and won't take much time or money to figure it out.

jet it.............all I have is the cam mod, rejetted, baffle pulled, and air box lid off. Best $20 mod there is.........counting the yz450f needle. Gave some starting problems, so we turned up the idle. Fires up every time. :D
