I am putting a used pro circuit pipe on a Blaster for a friend and doing the jetting. I am not to familure with the Blaster's jetting. I did one once before and think I remember putting a 160 main?? sound about right? Anyways, I will install the pipe and take off the baffle on the airbox, other then that it will be stock. Which main jet should I run? I also remember when I helped the last friend with a blaster that all we did was the main and didn't have to touch anything else, what do you Blaster guys reccomend? It will be running in northest ohio, so under 800ft above sea level or so... Thanks

 

I am running a 270 main jet at 5500ft with the toomey B1.

 

what has he got for a filter????
filter and pipe, I would recomend 200 jet, maybe one less.

 

Stock filter, thanks so far guys
