The bend in chain on tensioner side looks like it has a lot of adjustment to go and wear on cam lobes & rockers appear to be hardly marked, so it maybe reasonably young.
I'm just not happy to see such a feeble looking chain, maybe I'm just old school, having seen plenty of yesterdays motors apart. I have Googled to find a heavier replacement but cant find anything yet other than it has 122 links. I would take the pitch to be of common size but thats yet to be tested. Tensioner runner & forward runner have enough width to take a wider chain.
Is there a better chain available?
i have had several XR650R's 1 i recently did a full rebuild on after 27.000k's on the original timing chain no problems, i haven't heard of and t/chain failures either,
The HRC kit cam with a wider chain and wider sprockets to suit have heard deffering stories as the weather they can still be brought i'm sure honda Australia have no stock be think someone got a full set from the USA a little while ago
