Beta Rev 3 250 2001 Chain Tight.

[alvin123]

Just bought this bike and noticed the chain was too tight. Ok you're all thinking loosen it off. Firstly the cams are on the position where the full slack is allowed. Tried another chain with an extra link then it is too loose. The front cog is standard teeth and the rear is a 42 instead of a 41. the tensioner also springs up and looks ok.

Any suggestions would be most welcome.

Thanks

Alan.

It's possible that the chain is knackered and the previous owner just pulled a link to make it tight. Grab a link in the middle of the chain run on the rear sprocket and pull it off the sprocket. If you can see more then 1/2 tooth then it's time for a new chain. Of course check the sprocket for wear while you're at it. Teeth should be symmetrical, er symmetric... they should look the same on both sides.

I found that with my 2003 Rev 3 the axle travel available was not enough in all circumstances and at one stage needed to use a one and a half link. Whether or not this is a problem on a particular Rev 3 probably depends on the sprocket size combination in use.
