Hi All, I bought my '90 VR a couple of weeks ago. The guy I bought it from only had it for a couple of months and said he was out for a ride when it blew a radiator hose. He thought it needed a new head gasket. Anyhow I bought it not going. (I like making things work). I have tested the compression and got 90,100,110 and 165 psi. Added a bit of oil and all four went to 240psi (pretty high isn't it??) I pulled the motor out and have got the heads off. A fair bit of carbon build up on the pistons, top of cylinders and heads. I noticed that the line to the coolant drain was full of sediment and so was the water jacket around Number 1 cylinder. I guess it has been a long time since anyone has given the old girl a good flush out. I've ordered new rings, gaskets and hoses plus anything else needed and now waiting for them to arrive in Australia. I have had a good look around this site and I'm trying to figure out how the oil got into the coolant system. I suspect that the oil seal near the water pump shaft may have let the oil into the waterpump area. there was no water in the oil sump. I've ordered a new seal and mechanical waterpump seal. The bike is faded blue so I hope it'll go fast when I get her back together. It's got 46K on the clock and was imported to Australia from Canada about 6 years ago. Is there any other areas I should check before I start the rebuild??
