When I purchased this bike, the only thing wrong with it was the water pump seal had gone bad causing coolant to drip out of the weep hole.

I ordered the water seal (Mfg Product Number: 91211-KA3-761) online from Xtreme Motorsports for $3.77 + Shipping.

The first step for my bike was to remove the header and engine skid plate, then drain the old coolant. Here you can see the Titanium header on the floor under the dirt bike stand. You can see the brass fitting behind the drain bolt. Ideally, you should replace this as well as the one behind the impeller, but I chose not to this time around. With the cover removed, you can see the impeller. Using a 10mm socket, I removed the impeller. Here is the first view of the culprit causing the leak. As you can see, there is another brass washer behind the impeller. Close-up of brass washer. Yet, another close-up of brass washer. The cover of the water pump kept falling in my way, so I used a couple of zip-ties to hold it out of the way... Here is the cavity of the case that the water seal sits in. I used a pair of needle-nose plies to pull the old seal out. New Seal and where it's going to go. NOTE! Be sure that you have the SPRING-SIDE faceing OUTWARD! You can almost see the spring in this photo. This is the remains of the old seal after being pulled out a piece at a time with needle-nose pliers. I used an 18MM socket to tap the new seal into place. Using the socket ensures that you get even pressure around the seal as it's being tapped in. Replace the brass washer... screw the impeller back on, clean the area where the gasket will seat, then bolt the cover back into place. Add coolant and give it a test ride. Only adjustment I had to make was to tighten the drain bolt a bit to ensure a good seal. Last modified: March 10 2009.
