i just finished riding my 2002 bombardier 650 i was just crusing around with my nefew on the back, i never went faster than about 15 miles per hour, we road for about 30 minuets when we got back i notice a loud knocking in my engine, sounds like someones inside the the engine with a hammer trying to get out. im not losing any power and the quad still rides the same, can anyone tell me what can possibly be wrong with my bike.

On left side of motor, below carb, is a large 22mm or 7/8 bolt.
Remove bolt and washer.
Use needle nose to pull out plunger.
Clean plunger .
Clean out bore, that plunger rests in, with q-tips or lint free rag over blunt rod or philips head.
Spray bore with wd or lubricate with oil, re-oil plunger and re-install.
Re-install bolt/washer. Do not overtighten.
