Fido, See if you can get me the info on the chain tensioner. I would like to put one on my tryke. After a short trip the chain has already needs adjustment and I can see that it won't be the height of my day. So see what you can find. Thanks John

I looked in my so called files did not have any luck.// If I can recall we used a part from a bike a spring loaded arm then put a skate board wheel on it to roll on the chain I remember that cause I had to buy a set of four just to try it but it worked . Look at a mountian bike chain derailer it is not hard to fig what you need to do .You got me thinking now I will look in to doing the same thing .iIf you get it first send me a note.I wish I had kep better notes on all that stuff. But it is the same if I had known that i was going to live this long I would have taken better care of my self. fido

But I have to question why your chains are either getting loose or tight. To me that says something is moveing back there and is not tight enough.

Al... you are right... It is the design, the hubs have play and a weak soft metal sleeve that wears at the roller bearings at just 400 miles of use, that is with heavy weight like riding 2 up. And the swing arms in the rear to the hubs have light play, add it all up and it is trouble. I still have not made the new sleeves for the hubs yet but will this summer I am sure. Now on the newer ones John has looks a little beefier than mine I think and better design on the gear box I think for sure.

Tierod, take and run a string from front sproket to tear and make sure you are lined up. I had to change out the spacer on the real sproket as mine was off almost 1/8th an inch. Lee made a stanless steel spacer and we put it one, man what a difference

A chain that is too tight is going to wear quick too. They need a little bit of slack to stay free. Just going by what you do with a 100+ hp sport bike.

[Alleyoop]

Yep, if you push up on the bottom of the chain in the center it should move at least 1/2 inch to 3/4 of an inch.

My bike is almost new less then 200 miles and I have at least one inch of play and I do oil it and everything is tight. Maybe since all that miles is with two up and the swing arm is moving more then with one what do you all think about adjusting the shocks harder and tighten the chain to see what will happen. My friend just bought a 150 and the dealer who did the PDI took the factory chain off and put a after market on before he gave it to him. We both took a 60 mile trip and his is still tight. I am going to work on a tensioner and see what I can come up with. John
