Posted: Tue Dec 13, 2011 6:13 am Post subject: 1980 YZ 125 Bogging
My bike continues to bog mainly coming on the throttle out of turns. Down the straights wide open it screams but still cuts out a little. It idles great.
I have been through mains, pilots, needles and it still does it. Sometimes worse the leaner I make it with the needle.
I am starting to think that maybe two other things might be the problem. I have a brand new mikuni on it but am thinking that maybe the valve is sticking and not letting gas flow into the bowl.
I am also thinking it might be the ignition system. It seems worse when the engine gets hot. Would the ignition system cut out like this when coming on the throttle or does it sound like just a fuel issue.
The plug looks dry and black after riding. It cranks really easy. It revs up good on the stand.
So I just do not know which way to go to fix this problem.
