Re: riddle me this...
I gotta hand it to you. Making your front derailleur work with the Shifter Kit is a first!
Plus a tensioner on the right chain. Is it noisy?

Re: riddle me this...
Funny..I never thought about that.
I can't tell the difference in noise between the right chain with the tensioner versus without. The pulley is a sealed roller bearing, not friction. I keep it at shallow angles to put as little deflection on the chain as possible. It never made noise as a derailleur jockey, and I never even anticipated it to make noise as a tensioner pulley either, but, maybe the clutch is so loud anyways it IS making a racket and I just cant notice. Either way, it is NOTHING like the racket from the tensioners in the basic chinese kits. Seems dead quiet. A set of two sealed bearing pulleys like this run about $15-$30 (i cant remember exactly) at performance bikes.
Which brings up two questions for ya (Paul)...
1. How long does that chain stretch for? I know the engine slowly has to settle, yet mine has been clamped securely around some water bottle cage mounts (meaning it physically can't slide down the frame), and yet on every ride the chain seems to noticeably stretch. Even after I havent "messed" with the mounts for several hundred miles, it still gets looser every ride. This was before the demented eighteen speed conversion. Any thoughts?
2. Also, (if you can remember off your head), What are the thread patterns for the five bolts the chainrings mount to the freewheel? M4 1.00 *50mm? If I can get some longer main bolts, a call to Andy might be in order for some aluminium bling. I think my super top secret tooth number combos are gonna be a winner.
Thanks for your help.

I dunno... I just woke up, and Im gonna go find out here in a minute or two! (I put it together last night after having a margarita)
I took it up to 25mph in the dark last night, but it was cold, snowing, and I almost hit a deer. I didnt want to go any faster, but, I was basically idling. I doubt it will hit much over 30 on the flats, but I did this cause I live in the mountains and hate running out of gear on the downhills. I also did this to slow the pedalling cadence down so you can pedal at a reasonable speed with the motor....not so you can go faster, but so when you ride by a cop, you can smoothly pedal at 70 rpm like you are actually a bicycle rider. There are several other reasons also, like getting the chain off the 11 tooth rear cog (so it doesnt wear out) and letting the engine rev at whatever rpm you want at whatever speed you might be at (no vibration, quiet, etc)....
I am basically typing cause its cold outside and I dont want to go out yet.... naw screw it, Illl be right back.
A full report will be shortcoming!

Re: riddle me this...
Spillers,
I will jump in here to answer your two questions.
Chain stretch, probably not at least not after a very short while. There are 2 things that can cause the chain to loosen, engine twisting and engine sliding. If you installed the tie bracket between the rear motor mount and right bearing plate that will eliminate the potential for the twist. So the only other option is it sliding. You say that the clamps are resting on the water bottle studs, so that eliminated the clamp from slipping but that doesn't stop the motor mount plate from slipping slightly on the clamps. It takes very little movement for the chain to go from bass string tight to loose. This is the reason we just came out with the chain adjuster which also helps support the motor so it can't slide any more.
For the chainring bolts. They are M5 1.0 and stock they are 22mm long so you will have to figure out length for your application.
