GY5 - chain tensioner - huge improvement

[Frog]

Hi

as other have pointed out the Lifan GY5 needs a lot of chain slack - over 3 inches when on the side stand to make sure the chain does not get tight under suspension compression. 8O
To compensate for this I have just fitted a universal chain tensioner - cost about 15 dollars (£10 UK pounds in my case). The one I got is I think called CEMET - and is a pad rather than roller design. This mounts on to the little plate on the swing arm that usually holds the useless white plastic chain guide (that appears to do nothing!) near the rear sprocket..

I mounted the tensioner onto the front hole having drilled and tapped it for an 8mm bolt and mounted a stop for the tensioner spring in the rear hole - these are perfectly placed for the job.

The result is astonishing and disproportionate to the effort and expense involved - bike feels entirely different and has picked up an undefinable air of quality about it - smoother / less vibes and gear change improved. No chain slap - transmission is getting an easier time. Feels tons better.

If anyone wants a pic let me know and I'll post one but basically very easy to do and well worth it.
