Ok i recently posted about some unhealthy sounds comin from the ole girl. One of em is deffo clutch basket, the exhaust had a slight blow which is now sorted, the other one i have had a closer listen to and it appears to be abit of a beefy noise..

Maybe the big ends or cams.. SOunds abit high up the engine to be big ends so more likely camshaft noise... Is this another common problem with the older CBR 600 and whats involved in changing a camshaft?..
