I'm faced with having to run a chain tensioner on my bike. Who has run one on a Triumph and not had too many problems.

It's been suggested to me that a tensioner from a Yamaha Banshee is quite cheap, easily aquired and they work well....

Here's one I made, but haven't run it yet:



Spring from McMaster Carr: $4
Spare materials, nuts, bolts, etc.: $0
Shoulder bushings for pivot bolt: ~$3
Spare 101a durometer skateboard wheel from local shop (very important to support local skate shops!!): $6
Bearings: $3

Cheap way to make a tensioner. I was going to turn a groove in it for the chain, but never even got around to trying it out. Not sure I'm going to need to run it. So far I haven't had any problems because I'm only stretched 4.5"

make sure it is sprung and not bolted solid, it will crack the frame.
yes I realize that it has to be spring loaded and not rigid.

Thanks for the pic mcrad.

Serpentine belt tensioner.You'll need a wheel though.You could always run a gear instead of a wheel.I thought this one up for my BSA when places wanted $150-200 for their pre fabbed "one size fits nothing" setups.The skateboard wheels seem to work well.
