I started up my R40 again today and so far things went really well. Lots of smoke from the MT12, revving happy, but all of a sudden when I hit the brake, the engine revved at a speed higher that idle and constant. I pressed the throttle and it didn't do anything after the 2nd press. Could it have to do with the clutch? Thats the only thing I'm thinking because it wouldn't be the needle settings or air leak. Maybe I need to use different spacers in the clutch than the one showed in the manual. Threadlock was used on the clutch nut. I'm running outta ideas. This is really ruining the fun.
