86 yamaha phazer help
Good evening everyone, I am having problems with my old phazer an I am in need of some advice. The problem is, it doesnt seem to rev past 5000rpm on a hard packed trail. it kinda feels like it just runs out of power. When I have the track in the air, it will easily rev up to red line, with a very very slight pause at the 5000rpm mark. It starts great, idles like a dream, and takes off hard, (it even picked the skiis off the ground once)
Here is a list of everything I have done to it so far. I have cleaned the carbs several times, new fuel pump and fuel line, triple checked that the plugs in the carb are in the right holes, new spark plugs, cut the wire back on the spark plug boot, new belt, cleaned the clutches, checked the clutch alignment, it has a 5/8 off set. Checked the track tension, checked the Y pipe for cracks, fresh gas, removed the oil injection, unhooked the grip warmers as I read somewhere they can cause an issue, cleaned all electronic connections i could find,the track spins fairly easily by hand, but is definately harder when the belt is on, which I thought was normal.
Im sure there is more I have done, but just cant think of it at the moment. I have a parts phazer sitting here so if someone has any thoughts on something else I could try I sure would like to hear it. Is there anything specific that happens at 5000rpm that would make it stop there, or pause there when the track is in the air? Thanks so much in advance, i am looking for all and every idea i can get.
