Default Tension Is Building

For a future build , perhaps on a OCC Chopper , I am going to try a chain tensioner fashoned similar to the way Harley Davidson does it for the primary chain on their cycles . They withstand far more stress than a drive chain will put out from a china motor . I think it may be useful where mounting a tensioner is limited for space . I would like your opinions if you think it may or may not work . What got me thinking of this was after I turned a new skateboard wheel down to replace my original pully, I put inner and outer bearings in the new pulley and mounted it on my motorized bicycle . It worked great . Then I noticed that the pulley wasn't turning all the time as the chain moved across it at low or high speed . The pulley shows no noticable wear even though it remained stationary . So why not just fashion an adjustable shoe instead of a wheel , made out of a skate board wheel ? Here is a pic of a Harley type chain tensioner .
