Questions on jetting.

[03yamwarrior]

I pulled my carb off the other day and put a dynojet 148 in it for slip on and no airbox lid and it runs great except for if I stop after ripping on it it just shuts off and gas comes out of the bowl. I found a pic showing the diff between mikuni and dynojet jet sizes

should I be running a 152 instead or is something else wrong?

Mine did the same thing, it was hard to keep it adleing. The largest jet in my dynojet kit was 150. I put it in and it seemed to help. I actually recently just purchased a kit from jetsrus.com looks like that's where you got that chart.

Your floats stuck if gas is running out and make sure the screw to drain the bowl is tight! Take the plastic part of a screwdriver and tap the bowl and turn the gas and and tap it a few more times! If it dosent work take it apart and clean it!

The 148 should be fine if thats the only mods you have!

Ok I will do that. I forgot to check float height. Thanks. Will keep you guys posted
