I have a 96 Formula III and when driving it I get abit of hesitation. Very inconsistantly. Sometimes it works great when you punch it other times it bogs. Choke not sticking (anymore), synced carbs, plugs firing good. It always starts good. I am thinking electrical. Any ideas?

service the clutchs, both of them ,clean them real well and look for wear ,put a new Brp belt on it not dayco junk ,go thru your raves and clean the cylinders port, and she will put a smile on your face every time you hit it

I would definetely clean the raves, they could be stuck open. But since you mentioned the choke not sticking anymore, I would clean the carbs, not a hard job and one I do every year. I have always found hesitation to be carb related and very seldom electical.

I am not sure how to clean the raves. I know hesitation is normally carb related. Hesitation is just the best way to describe it. Maybe missing could describe it, but it is very inconsistant. That is what makes me think electrical. The funny thing is it was just serviced before this started happening. The shop said it must be something I did to cause it. Wanted more money to look at it again.

google " cleaning rave valves " and it wil direct you back to this web site for full directions.
Check your electrical connections around the coils and motor. replace your spark plugs.
Run premium gas. Clean drive pulleys and make sure you have a new belt.
Above all pick up a shop manual!! they are worth their weight in gold. They have a really good trouble shooting section which will help eliminate what the problem isn't, then if you do have to take it too a shop you will have some idea were they should look.
If your problem is electrical it is very hard to diagnose unless you have the equipment.
As far as a shop is concerned, go to a Ski-Doo dealer. I've seen more people waste their money taking their sled to the local guy. Dealers know your sled and all the weird quirks they have, yes they are more money but they will fix the problem first time around.
