I got a 96’ Yamaha Blaster that I put a Vito’s 240 kit and +3 stroker crank off my other blaster. Will run somewhat but would smoke after warmup not during warmup when you’d get on the throttle it just straight up bogs and has no power whilst blowing blue smoke. So I took the head off today to...

I got my 1999 blaster and it needs a new right crankcase any ideas on where to buy one from looked at a few websites and they were unavailable. Wondering if it could be welded or what the best thing to do would be. Anything helps thanks.

I noticed when I stopped that the base gasket up in the front right under where the exhaust flange mounts up there were some type of...

So I threw a 260 in and it fired up and idled. significantly helped with power but after a few minutes it got super hot and the pipe was glowing red hot. The spark plug is a BR8EG

Ok thanks will have to try that tommorrow after school

Fixed the issue turns out I had a sheared woodruff key.

Have you checked the woodruff key to see if that is properly installed. I was having the same problem a few weeks ago and found out my woodruff key was missing and that would keep it from starting.

So recently I was riding my blaster around and all of a sudden it backfired a few times and will not start anymore. Quad has 160 psi for compression Vito’s +3 stroker crank and 240 big bore kit. Blaster gets great Spark and timing is right. Fuel is fresh and getting to the engine. Any Ideas on...
