Like an idiot, I have bought a 1984 half faired basket case Austrian origin VF500F to fix up. I managed to hear the engine before I bought it, and it had a camchain rattle as the revs increased. At idle it was OK. I was kind of hoping a tensioner was sticking so it would be a straightforward fix. However, having opened the engine up I can’t see any evidence either tensioner is sticking. It does look like the tensioners are at the end of their travel so maybe the camchains are worn. I am sort of surprised as the dual link chain seems over engineered for the task.
I have to decide whether to repair or donate to colleague who will use in an Applied Mechanics course at work.
I have a good spare engine but seems a shame to scrap an engine that is fine otherwise. The valves look good and the cam followers are fine although one exhaust cam has a few pits. The odo reads 68000 km on it and the condition of the bike is consistent with that.
Anyone replaced camchains in a VF engine before? I assume you have to buy endless ones and split the cases? I can see getting the pistons back in the bores being a challenge.
I’ll probably end up posting this to other forums too so apologies if you see it elsewhere.
