Just wondering how many miles are in an XTZ 750? 70? 80,000?
what, miles of cable ? wire ? Are you talking with replacing worn parts or just run into the ground from new ?
I'd expect at least twice that! ('though you may have to replace the reg/rec, fork-seals, steering-head bearings and the cam-chain tensioner(s))
150,000+ KM with good servicing. The 5 valvers are known for oil usage. 1L per 1000KM is considered acceptable by factory standards. If you live in the UK 300 quid will see the top end overhauled. Go for the 530 chain conversion and they'll last too. justAL
