Well I was out today for a ride and when I went full throttle with the bear it would not rev right out like normal, it would only rev up so much it would also spit and spudder to. So I stopped and put it in neutral and I held it wide open it would rev up so much and not rev up like it should( normally I can get it to rev out higher). I changed the plug on the spot it helped a bit. Could this be carb trouble? or could it only be anadjustment like adjusting the throttle cable?

Thanks for your help !!!
Im selling the bear and im going to try to get a 350 honda straight front axle.

 

You have to do some experimenting, could be the carb, could be the cable, could be some sort of electronic rev limiter you in advertenly engaged, could be clogged air filter, clogged exhaust, water in air filter, and 90000 other things, just gotta look at stuff and use intuiton. First thing first take off the throttle cover and see if the thumb throttle is pulling far enough. If so your good there. Next listen to it to see if its makes any noise before it or if its like an instant deal, if its almost instant it may be electronic, if its kinda an onset then its prolly carb. My guess anyways. If all else fails have somone else look at it. I spend 30 minutes pondering over mine smoking bad and running funny, then my dad walked over and said "sounds like choke is on" Deeerrrrrr..... ooopppssss

 

I just cleaned the air filter and re oiled it. I think the trouble is in the cable because it was a bit stiff compared to normal.
