Hi i have ben offered a 2003 Crf450r, the guy said it was a bit tappy!!
Here is his reply about it
Hi mike,
I believe that you can here it tappitting if thats a real word? Basically when my friend bought it it had just had a top end rebuild and after a few rides it started making this noise so he spoke to mike bavin motorcycles who told him that its the valve shimming because of the rebuild bedding in.
I will double check what ive told you with the owner and will email you if that info is wrong.
Regards
Is this possible or is he telling porkies?
How long does it take to have done?

Fair enough but do they just wear quickly or does the metal just weaken?. My sons KE100, just holed a piston at 12k due to some ham fisted moron. I suppose it was getting near to the end of it's service life but just came a bit sooner
I think a stripdown is needed. Regrease all the lnkages, new fork seals, repaint the exhaust and a couple of patchs. It may be wise to slip the head and barrel off, check the bores and rings.
How often do you guys change your top ends?
