k its been runnin fine since i got it stated. the idle jumps until it warms up, and there is a clicking noise. when the clutch is pushed in clicking stops. i remmber tightening the clutch good and tight when i put it on. what could the noise be. also it never overheater, i took the exhaust off, (from muffler back is all) and now it overheats. got a new thermostat still overheats. the cooling fan does not come on. im sure this is just coincidental tho and has nuthing to do with the muffler. also since ive removed the muffler, it has a hard time starting. i reset the computer and it started fine again still starting to get warm and no fan. i turned it off and finished doing the body work ive been doin probly 2 or 3 hours and the same thing it wouldnt start. there is power and the battery is puttin off 14 volts connections are good. the starter wotn even click over. i think it may have sumthin to do with the neutral safety switch because when the clutch is pushed in about half way or more the battery and program fi lights come on. i apprciate the help for any of the problems listed. thank you -kevo
