I really like the one that ThatsDax sells. I replaced the one that came with my kit with theirs. It has a ball bearing in it that made things run smoother for me. Some other people remove the tensioner altogether.

I'm pretty fond of the skateboard wheel too I thin them on the lathe and cut off the outer rubber or what ever that stuff is then make a little shoulder on each side seems to work very good.

I grind the groove the old fashioned (or hard) way- on a bench grinder.

Hey Norman- I never knew there was an "outer tire" on those things and I was grinding the groove into my first one and the "re-tread" flew off like a road gator from a 100mph semi!

is there a downside to going without the tensioner??
Compared to the stock chain tensioner, I have found absolutely no downside to going without the tensioner. In my case, the stock chain seemed to be stretching bad the first 100 miles WITH the stock tensioner but immediately quit as soon as I removed the tensioner. I cannot comment on spring loaded tensioners because I have not tried them.

When I was using the stock tensioner without any mods it was a pain to adjust the chain. After adopting the "T-Shirt" solution posted by MotorbikeMike I found it much simpler to drop in 1/8" shims to dial in the chain length and have not had to adjust it in the 200-300 miles since then. Not only that, but my chain has run quieter and I no longer worry about the chain getting thrown from the sprocket.

Some guys use nuts, half links, or other stuff for spacers but I found it worth the $3.00 strip of 1/8" flat stock from my friendly neighborhood hardware store and about 5 minutes work with a hacksaw to make the T-Shirts:
