Fave chain tensioner?

[dumpydoodoo]

I bought the non-billet, case-mounted version because it seemed the most reasonable, but will entertain what experienced builders like.

The 4 bolt kit one on the pedal side and weld the small 1/2 on the chain stay... No tensioner on the engine side... Or a spring loaded one for a pit bike on the pedal side...

I've run the wiperman as a drive chain and has little resistance on the older 6mm grubee engines GT5 ... The new ones need the sprockets ground down and reshaped to fit by 1/16" ... The RK mini will out last several motors just to break it in

There is no reason for chain tensioners if Diamond Roller chain is used.
Diamond-Drives by Timken - Heavy Duty Industrial Chains (diamonddrives.com)
Tensioners are trouble used to compensate for junk chain. My only tensioner went to recycle.

Experienced builders don’t run a tensioner on the final drive.

Tensioners are trouble used to compensate for junk chain.

I always thought they were there for rag joints which theoretically would never be on center.

420 Is thick and heavy... Is going to robb a lot of power turning it and isn't that much stronger than a quality 410-415 chain... And those tensioner with the spring are more problems... You only need a tensioner with a swing arm with poor geometry
