Hi Wayde, it's been my experiance that half-links are weak and problematic. This is wht I developed the "T-Shirt".

Tine will tell on your bike, but I've had half-links fail even on the people chain, so I will never trust one on an engine again.

Mike

I took a few links out of my motor chain and then used the tensioner on the people chain. The tensioner doesn't get much use so should last forever. Seems to work fine after I got the tension on the motor chain about right.

All I can say is tensioning the chain is the biggest headache so far.....I don't mind taking links out (kinda fun really) but it just seems like I can't get the tension just right and the tensioner seems to interfere more than it helps. Also it seems like my sprocket has a small side to side wobble (NOT up and down alignment). Maybe one side is tighter than the other......

On mine which I probably did wrong. I measured the distance from the sprocket to the first spoke one both sides of the nut. i tightened the nuts till the distance was the same for all of them. Not sure if that would help. but yeah it was a pain for me and i am never sure I have it right.

Short of mounting the sprocket on a grubee hub or mounting a custom(ized) sprocket to the disc brake hub it is very difficult or nearly impossible to have a perfectly mounted sprocket with no side to side or up an down wobble....You can get very close tho or at least close enough..

Actually that is a good idea!! Don't know why I didn't think of measuring it other than lack of O2 to the brain
