Ok heres the catch , i have to re-jet my friend's 300ex for him on saturday , its running lean now.
Ok right now hes running a dyno jet kit with a 128 main and the dyno jet needle on the 3rd clip.
The quad is bored .80 over with an 11:1 piston, it has a uni filter with 5 uni vents in the top of the air box.
It also has a full Dg exhuast (no discs).
This jetting is for sea level.
What do u think he should run for needle/main jet setting. I just want an idea because I am kind of confused on what MJ to run since the dyno jets are diffrence sizes then regular jets.
Does anyone have any idea what size MJ we should run in it because hes going to buy the jets saturday morning and we don't want to waste a ton of $$ on jets he doesn't need.
Thanks.
