Remove and lay spark plug (still connected to wire) on engine. Should see a good spark whwn cranked. Remove fuel, turn petcock on with vacuum pump to the third line (if equipped), should have good flow of fuel. If oil not more than 1 qt down, shouldn't affect it. I would empty the gas and put in frsh, with some cleaner (2 oz Chemtool).

Check the exhaust. Sometimes the muffler will partially collapse internally, (louder noise). This restriction in the flow of exhaust gases is commonly called "back pressure". The back pressure will cause a lack of power and loss of higher revs.

Disconnect the exhaust system and ride around the block without a muffler. It will tick off mom and dad but the kids will love it. If the problem instantly disappears then you can go find a new set of pipes.

Please rate this solution as "FixYa" ( if it works ). Thanks!

Does the engine misfire? Check your HT leads (connect the spark plugs to the coils) is one of them loose?

sounds like a ground problem. look for where the wire loom is grounded to the frame. it's probably loose.
