It does sound like an ignition timing problem, but could also be a breathing issue, air flow in or exhaust flow out could be restricted i.e.:dirty air filter, excessive carbon build up in exhaust pipe from burning too much oil or rich fuel mixture.
possibly and more likely some junk got into your fuel system and partially plugged up the main jet in the carb, -or has the needle on the slide been moved? The little circlip at the top of the needle, if it has one.
1.Replace the spark plug, check gap, check spark, it should be bright blue and fat.
2. check the fuel filter, if no filter check the carb for dirt.

HELLO; No, the 87- 89 are only for those years, yamaha changed the wireing looms three or four times I can't remmember, youll have to get one for your year of quad for it to work right. Check on line for a used one or new at better than dealer price. GOOD LUCK.....GREASY.
