i have a 88 yamaha terrapro, after about 15 mins of riding it starts missing bad for about 10 mins, then runs like its brand new for another 15 mins or so then does it all over. i have rebuild carb, cleand fuel lines, new plug. does anyone have any help for me cause its really ticking me off. ignition coil maybe??????

 

check to see if spark is good and consistant, and make sure fuel is flowing good, make sure petcock isnt clogged and that the fuel bowl isnt sticking or way outta adjustment or something.

 

Check gas cap vent and carb vent lines.

Or next time it happens open the gas cap and see if it helps.

 

thanx dude
