Hello I have a mint 92 blaster with a rechambered head, wiseco piston, boyeson reads, fmf fatty , oil inj. block off, and a sudco/kehien 32 or 34 mm carb(pj67). It has great low end and seems to have lots of torque but it will not rev like i think it should. It seems you have to short shift it. Is the carb to big ?/ I would think that would hurt torque. ?/ ALso anyone have a similer setup they can give me help with jetting.

thanks

 

boost port your cylinder

 

I have no problems with porting a 4 stroke motor but haven't got a clue what you are talking about on a 2 stroke. I did clean up the figer ports and the intake divider but I did not riase or lower the port timing at all. Any web sites showing this.

thanks
