The *BEST* Solution for "THE" tensioner/pulley
Discussion at Motorized Bicycle Engine Kit Forum in the Motorized Bicycle General Discussion forum. Very Very nice. Its less welding and more eye pleasing than mine. Good work my man. Thanks for sharing.

If I'm seeing this correctly, (master link just leaving rear sprocket?) I'm not being picky here but you should really turn the clip on your master link around. The closed end should enter the engine sprocket first. The way you have it, it can get kicked off by interference with the sprocket/ clutch actuator case. Just an observation that might prevent a chain loss. If I'm seeing it right.
Tom

Having no pensioner would be nice no doubt but don't forget that no matter how tight your chain is it still may need a tensioner. Ive built 10 bikes now and some have output sprockets that are almost a half inch out of line with the rear sprocket and the tensioner fixes this. It would be a real pain in the butt to fix this problem without it. For the record, i like having a spring tensioner but i have no problem with the stock one. Besides having to bend some to get them to line up there are little to no problems once set up. |

No tensioner would be nice and I could have done that, but what I found in my application is that the chain would rub the frame chain stay. By lifting the chain in this area it allows the chain to clear the frame. Sometimes the bike tells you what it needs. |

The weld on tab is slotted to corectly adjust chain tension. Works great and have had absolutely zero problems. | Very cool! Really like the looks and function. Purty work Sport.

Dang Tom! With glasses on and magnifying glass, (no kidding) still am not sure but think your right. Great catch.
Chain coming apart is a really bad thing at speed. I really can't see if it is reversed though Sportcarpat.
Tom makes fun of me for remembering it as a lil rocket propelling the chain. I remember the ball bearing chain cages on the bottom bracket by; protect your balls, face 'em inward" (LOL, I are slow and actually need these weird lil ways to remember stuff)

Photo Shop...I can ANYTHING with Photo Shop. Actually I saw his master link on my old 80s vintage monitor at work. I downloaded that pic to PS and enlarged, enhanced it and used a shapening filter. It looks like its backwards but I'm not absolutely positive. I'm still waiting for a reply from him to confirm.
