I have a blaster and it has a bog to it. I just rebuilt the top end and bored it over .40. If u have any suggestions please help me.

 

Did you jet it? You HAVE to jet it when you do something like that.

 

Yes i put a 260 main jet in it. I also have a fmf pipe system. v force 2 reeds and a k+n air filter. It mostly bogs in the lower gears so do u think i need to change the pilot jet also? If so would i go up a size or lower to take care of the bog?

 

If I were you I'd go to www.blastercentral and look for "jetting 101" that should tell you all you need to know? They have a guest pass up now so anybody can check it out.
