who sells the leakdown testers for $30 dollars? today i started my blaster for the first time in a while and it acted like it may have an air leak. it was running very lean, bogging down, wouldn't rev all the way up, revving up by itself, and it just wasn't acting right at all. i know the carb didn't get gummed up because i always turn off my gas and run it out after every ride. anybody got any ideas? i think it might have an air leak so i need a leakdown tester but maybe not somebody tell me what you think.
