I have a 2004 blaster I picked up. It’s idling all kinds of crazy and racing all over the place. When I pull the choke out to started it revs super high. I took the carburetor off cleaned it checked it out it has a 240 Main. Only thing done to the bike that I know of is a pro circuit exhaust. It has 118 psi compression. Any ideas of what’s going on with it. Also has a Tors eliminate kit on it. I was thinking the reeds when I pulled them off they’re not cracked but they are not sitting flat. Also waiting for a fly wheel puller. Any suggestions would be super appreciated
Blaster acting weird

Most likely an air leak. You could visually check carb boot for cracks by slightly bending it. Most likely crank seals, they are at least 14 yrs old.
Are you using oil injection? If not is the nipple plugged/capped?

Leakdown testers are a great tool to have for these. It takes the witch hunt out of finding air leaks
Did it leak down test and everything is holding well. It’s not losing pressure after 15 minutes and I sprayed the whole motor with soap and don’t see any leaks. Any other ideas.
Usually want to test at 5 or 6 psi. To high can create a leak.
Hey Joe, how could it have held 8 psi for 15 minutes..... and then you detect a leak. Just wondering. I've never heard of anything holdling pressure.... and then starting to leak.
For now... once I get it all back together I’ll do it again. Waiting on a base gasket. All my shops are out coming on Friday
Thanks for the info.. the cylinder is stock bore so hopefully it’s not been beat onI wouldn't try the 8psi again5 or 6 is good
