I have a stock Blaster and need help on exhaust and jetting. Which exhaust would give me power through bottom, mid, and top Graydon Proline PB phantom or Hetrick Racing. What would be a good jet combination. Thanks

 

290 or 300 and go down from there i runn a 280 with fmf and k a n with no lid at 1174 feet out here.

 

real mikuni jets for the blaster at www.jetsrus.com

 

For a filter, no lid, and fmf fatty I'm running a 350. I don't know if that's too much or not. Would too fat make it feel doggy on the big end? For elev.: I'm in missouri.

 

All of those pipes you listed are exactly the same with a different sticker on the silencer. They are all made by powerpros. as for jetting with a stock carb, start at a 280 main, needle on 3rd clip position.

 

350 wow thats way to fat

 

A 340 also came in my jet kit. I put it in yesterday. It seemed to help some. It feels like it cleared it out a little on the big end. You still think that a 280 is closer to what I need?

 

i tried a 290 in mine and its to much its vary black to rich whats your plug look like? also any one got a blaster cylinder for sale?

 

I'm going riding on sunday. I'll get a really good idea on my air fuel mixture then.

 

Is the number one sure fire way to tell mixture on one of these to look at the plug? I need to put in my new plug and go riding, then I'll be able to really tell what I need. My old plug is kindof black with a dark browny color on the tip. It looks like it needs to be replaced anyways. It's kindof pitted on the tip.
