I am considering buying an 06 or 07 CRF 450 and I wanted to poll some current or previous owners on the durability, quality, and routine maintenance on Honda's big bore 4T. Im not looking for general 4T maintenance tips and advice, I currently own a 450 and know what that entails, so I am looking for Honda CRF specific experience.
I have heard that the CRF450's have had some valve durability issues in that they require more frequent adjustment and shorter overall lifespan than the other manufacturers 450's, is this true and approximately how often does this maintenance need to be done? I know what the service manual says so I am not interested in that response, I am looking for real world experience and actual observations from owners.
As far as problems go, what issues have you owners had with your CRF 450's and at approx how many hours did the failure or problem occur?
Has anyone experienced a gasket failure that allowed the engine and transmission oil to mix? If so when did that happen what were the signs?
Any other input is welcomed and thanks in advance.
