Weird noise and unrelated oil leak

7 posts in this topic

My 450 has a weird noise. When you give it gas (only) it squeaks. Like a mouse. Even in neutral going down the trail. Any ideas? No it's not the chain.

Also I have oil leaking from a bolt that hold the cylinder down. It's the bolt that the clutch cable bolts too. It's minor but annoying. Replace the washer, tighten, any ideas?

I don't know, both. Maybe it's a habitual holdover from working around cars for so many years, but I sort of expect an '05 model to get some kind of owner support. Come to think of it, it's a dirt bike. They probably have a clause that says the warranty ends as soon as you start it. What was I thinking?

If your squeak sounds kinda like a whistle, and it gets higher pitched as the engine revs higher, this is normal, it's just the sould of air being inducted into the air box as far as I can tell.

Normal, I think it's the carb, but it does sound like air getting sucked by something. Mine has done it since the beginning at small throttle openings. I've got the 426 but I can see how this would be similar on both bikes.
