Finally got a bike yz450f now a question?

[drrm123]

I finally found a bike with-in my budget. 2006 yz450f for $2400. Now I need to know how much noise is considered normal? Listening to engine you hear a rattle at idle like piston slapping cylinder wall and when you rev engine a little higher it goes away is this normal? Will probably tear apart and do PM but just wanted to know if anyone else with similar bike has same sound.

I have an 03' yz450f. I bought it new. It has had a lower end rattle since day one. Almost sounds like a rod bearing. If there is no metal in the oil filter after running it for a bit, I wouldn't be to concerned. They have a normal knock to them.

Thanks so now I can start spending money on some new plastic and front wheel bearings.

Spend the plastic money on gaskets so you can tear it down and measure everything. A 2400 dollar 06 450 will probly need some work, no matter what the Craigslist ad says......

Excellent idea. :cool:

It's better to know for sure what is causing the noise rather than taking a chance on your 2400 dollar 450 becoming a 4400 dollar 450. If it is a worn piston, the skirt of the piston can break and cause many dollars worth of damage to your engine. It would also be a good time to check your valve train and crankshaft.
