1990 cougar knock
I have a 1990 cougar 500 Suzuki I believe. All was well sled ran good snow was nice changed plugs and tuned th idle and then there was a knock low in motor. Sound appears to be located in the clutch side of case. When I rock the clutch back and forth i have a faint knock just at clutch connection point or just inside the case. Is this a bad bearing , is it immediately terminal, how much does it usually cost to get this fixed. It has been 28 years since I have had a sled and have been enjoying it a great deal . Not sure how much a excellent looking 1990 sled is worth with a bad bearing or should I just ride it until it goes no more. Have not ridden it since noise was discovered but seemed normal for power when it was discovered. I know the smart thing is to take it down and find out but not in a position to spend a bunch of money on finding out. Any information or suggestions would be greatly appreciated.
