jetting question!

[05blasterkid]

I recently blew up my motor on my blaster and im wondering if anyone here thinks its because of the jetting? all my mods are in my sig and im running the 310 main that toomey gave me with the b1 kit what do you guys think is that too high or not high enough

I dont know stock jet sizes, I run a Keihin. I can tell you that your not on the lean side. What will through things of is the bigger carb and +3 stroker. We need to know the exact carb size. Air leaks can hurt a engine fast. Check that.

No, the 310 is plenty big. When you rebuild your topend, get a leakdown tester or make one. There are several places that can leak and that is the best way to find them. Air leaks lean you out = new top end.

yeah... 310 is fine.... or rich if anything... u probably have an airleak or a possibility could be that ur k and n sucked up something small (i.e. sand or fine stuff like that) and if that got into ur cylinder that will cause it to blow

it was prolly an air leak that made it run lean

always check for airleaks....i put some yamabond on my reed cage and intake boot and around the base gasket and it works great..just not on the head gasket
