I Have a huge problem with my freinds crf450r from 2002
The thing is that it bangs/shots in the exhaust very much every time that the throttle is shut off it also runs uneven i idle. Over the winter the engine have gotten a new Piston (original parts) I have checked the valves, and the Camshaft timing is absolutly correct. The engine tends to be running very hot (exhaust pipe is very red, more than normal) we have checked ignition timing with a timing light and it also seems ok.
I am kind of running out of ideas :think:
please give me a hint
