91 blaster jetting

Recommended Posts

what are some jetting recomendations for a stock blaster with a DG pipe? I think that my jetting is out of wack because it keeps melting the rubber tube that connects the pipe to the muffler.

too lean would cause the exhaust to run hot? I was thinking too rich. But I'm no jetting expert. What do you think I should do? swap the main jet?

A lean condition causes the exhaust gas temps to go up.

Do you have the stock jetting now?

I really dont know. Got the bike used. I'll have to take it apart and check. What would you recomend with a .02 over bore and a DG exhaust?

If it starts fine then the pilot is probably fine. If its being ridden in tight terrain(ie mostly in middle throttle range) then raising the needle may all be that is necessary. I'd try that first. If its still running hot then go up a size on the main jet too.
