banshee troubles

[jkent22]

hello everyone. i am having some problems with the 1987 banshee i just bought not to long ago so i figured this would be the place to go. well here it goes...my banshee isn't running right. the left side spark plug looks new and the tip isnt burned or discolored at all. here is what i know...both cylinders have around 120psi, both plugs spark, im running premium unleaded gas mixed with yamalube 2s oil (32:1), both carbs were just cleaned and look good. when running the left side pipe doesnt get hot so obviously there is no firing in the cylinder but why? when i pull the plug out its hot but has been firing. also, the banshee wont idle anymore? ideas? maybe this is a super easy problem, im not sure, i don't know much about 2strokes. any help is great. thanks much

Sounds like a carb is out of sync or needs to be adjusted.

My son just got an 87, was doing the same thing. Cleaning carbs etc. didn't work. Ended up pulling flywheel, cleaned poles on stator, cleaned pickups on outside of flywheel, set gap, problem solved. Good luck!!
