I would probably just get oem parts. Can you please share a link of the vac kit?

(click the picture) There are tons of resellers for these Mityvac kits, you can find them on Amazon too. The kit comes with two adapters. The one screws onto your radiator in place of the radiator cap to pressurize the bike's coolant system. The other allows you to screw the radiator cap onto it to pressure test the cap.

My water pump seal started leaking a few months ago. I had no access to a new seal here in Mexico so we removed the water pump and seal, cleaned the seal and re-installed it. Has not leaked since. May want to try that if you are waiting for parts.

Thanks! It's a long winter here, so I'll try cleaning the seal before I order a new one. I haven't tore it apart yet, but it looks like it's part #2 that fails and allows coolant past? They want $46 bucks for that bugger! More reason to try and refurbish the old seal.

I assume you mean you added rebound damping to Borynack et al's stack, not added to the factory stack. Because that factory rebound stack is retarded; 30 0.1 shims don't allow for a very plush setup. That is why you can just about lock the shock up by turning the adjustment all the way.

Nope. A flat blade screwdriver will open it up and a 12mm socket will take the valve apart. There are some special things that need to be done, such as filing off the flared threads on the shaft, and bleeding it, and learning to avoid an oil shower. But once you have done one, they are all pretty much the same.

Well hold on, there is one special item, nitrogen. If you don't have a shop near by, you will have to get a bottle, reg, and the aircraft strut filling valve thingy.
There are lots of videos and how to pages out there, check a few out. People have different ideas and you can find what works the best for you. For example, I find bleeding through the compression adjuster worked best for me.
This is a good start here: http://www.borynack.com/xr650r/KYBShowaShockService.htm

Question for those of you that have had the head off of their XRRs. What kind of sealant do you put in between the head and the piece that holds the rocker shafts and cam shaft? Is it possible to re-use the large rubber plug that sits on the outside of the head?

Thanks in advance!

I also was able to do a dynamic test (engine running) and confirm that cylinder pressure was not finding it's way into the coolant (ie blown head gasket). Plus it comes with an adapter to make sure the radiator cap is opening at the correct pressure. Definitely worth the $35!


Unfortunately, I still had some coolant leaks after letting the bike idle for 5 minutes, though it wasn't as bad. It appears I need a new waterpump seal, as coolant seems to be coming out of the weep hole.




Can anyone recommend a waterpump rebuild kit?

Glad to see you making headway, What did you end up doing with the hoses/clamps?

That clamp above looks good, NOT overtightened.

Three Bond case sealents are what have been recommended to me. Permatex is probably similar.

I reused my rubber plug, but I also gave it a layer of case sealent. No issues.

I used Honda high temp gasket sealer - Hondabond HT. I re-used the rubber plug and also put a light coat of sealant on it.

Yamabond, hondabond, three bond, all very very similar products. I bought Yamabond to seal my case halves this go around though. I'll use in my head cover as well.
