The only answer to that is exploratory surgery.

Who was the last person to add fuel to the tank? We see problems such as this all the time. Somebody borrows a bike and somehow gas (not premixed) is added from the wrong container and ... there you go. If it's the rod that means a complete disassembly and repair. To pay a shop to do the...

We're not so concerned about wear, we replace parts before they wear out. What we are concerned about is getting more power and not having a catastrophic engine failure from inadequate lubrication during abnormal conditions. It's long story but one time we were able to continue on for more than...

All the major magazines have done this test over and over and the results are always the same. For the typical dirt bike 32 to 1 is the optimal mix ratio. That's what all the factory teams have used (in modern times), that's what all the magazines use in their test bikes etc... etc.... I know...

32 to 1 here. I would rather buy more oil than buy more engine parts.

The Wiseco pistons are a bit heavy and noisy but much more durable. We used Vertex pistons (they make better power) for a few seasons and skirt cracks were a real problem. You can't leave it in there very long, you have to keep an eye on them. From by experience I think every one of them is a...

If it was working ok when you last parked it, as gasgasman said... the plates were probably just stuck together. Did you ride it at all before you took it apart? Often when they're stuck if you ride it a bit they will un-stick. Once you are rolling along in gear pull the clutch lever in and step...

We should have asked this first but I are sure it is overheating? And why do you think that? Any chance you missed adding oil to the gas? It's very common, we see it all the time in our shop.

That doesn't make any sense, all the manufacturers have representation the UK. Have you checked with John Shirt and Vic Eastwood and Apico and Wossner?

Water in the oil is sure sign of leakage, most often the water pump seal but it could also be a failed side cover gasket or a warped side cover near the water pump. Also look for a warped cylinder head and/or cylinder allowing combustion gases to get into the cooling system. This may be tricky...

Oh yeah they do... I never really paid any attention to what they were doing.

Interesting. What year bike did you try it on?

Just try the 250 pipe, you might like it. Pipe design is more about porting specs than it is about engine size, within reason that is. Our 250 pipe worked great on all the all three engine sizes.

What do you guys want to see available there? What parts do you need on regular basis? Or what parts do you always have trouble finding? Any other suggestions? Thanks, Steve
