I have a 89 500 Quadracer that has a cooling problem. While running the cylinder gets hot but the hoses and radiator don't.

While running I pulled off the return hose(head to top of radiator) and water was just dribbling out.

I ran water through the system via a garden hose and the water was coming out good.

I pulled off the side case and inspected the waterpump. The impeller looked perfect and doesn't spin w/o the motor turning over.

So what do you guys think is the problem?...air in the system and the impeller is cavitating?..any ideas on a fix?...Could it be the radiator cap?

The bike has seized before because of this problem and it is getting expensive to fix.


Thanks
Brian


By the way, I love this new UBB

try 60% distilled water/ 40% hi quality anti freeze. Run atleast .003" clearance and stay away from Wiseco when running such a big piston. Also run engine, take radiator cap off and see if water circulates. It might still be water pump not turning somehow.

 

Jerry, What is wrong with wiseco over bore pistons? I have a 89LT500 and I am running a .100 over wiseco in it. Can u give any info? It would be appreciated......Herbert
