i have a 87 warrior it has a 20 over piston and has a stock pipe and a kn filter and holes in air box what should i jet it at i live in the boston aera it pops when its cold when i give it gas but when it warms up it runs great what do i do????????????

 

i would half to reccomend a jet kit they are very help full un less some one on here knows what get to use

 

Have you checked you plug color? That will be one indicator of if you need to rejet, though it sounds like you do. As a good start, I would purchse a 155 main jet, and then also get one above and one below size. So that would be 152.5, 155 and 157.5

I found that with my uni filter and FMF pipe my pilot is too lean even with the box cover on. With the trails we have around here I don't often spend a lot of time past 1/4 throttle or so .. just little blips. I did have a 160 main jet installed, but that was too rich even with the box cover off. So I have a 155 now, which I plan to install sometime in the next 5 to 10 years .. or whenever I get time at it [img]i/expressions/face-icon-small-happy.gif[/img]
