my blaster is up and running with a 280 main jet but i have a 290 and a 300 its the stock carb kn filter no lid fmf pipe boysen reeds .040 overbore all ive done is fired and checked for leaks not rode it kinda scared to you think im close to the right jetting to start with id hate to trash a new motor should go higher what are u guys with similar mods running
 
that pretty close to what your ganna end up running but go take it for a ride and do a plug check for us and then let us know what happend
 
I rode it for a few earlier and pulled the plug it was slightly oily and had a light tint grayish in color on the porcelin.It runs great no bogging or hesitation so ill just be pulling the plug routinely so i know whats going on in there.

Its finally all done ill be posting pics soon.Thanks every one for the help.
