Chain Exposed!

So tonight it got my chains back on after a tensioner accident. It's been a journey to get here and it seems i may have to continue because im not in kansas right now and feel pretty lost.

heres some photos of my chain bare naked lol

the facts:

the tensioner keeps wanting to bend into the spokes.
the little white wheel is pretty chewed up from the first time i rode....
the upper holding blocks of the motor seem to have scratches from chain contact.
Chain is dangerously near to the thickest part of the tire.

the only improvements now that ive made is to bore the rear sprocket to fit snuggly not tight.

the chain is 1.5 links shorter than before.


now ive been thinking, before i get to turning the engine on, what if i make a spacer to thicken my rear sproket? that way the wheel clears and the upper holding block clear bit more...maybe im rambling with anxiety..

your experience, what does it say?

one thing that will help clear your tire, it looks like you sprockets on backwards. if you flip it around it should give more clearance

I have had good luck with rubber under the tensioner plates...helps keep it from rotating under pressure
hope that helps

ps...agreed on flipping your sprocket

With HT tensioner brackets etc i'm a firm believer in always bolting things in 2 places,if possible:

LOVING THE CHAIN TENSIONER! i was planning on making a rounded ends aluminum ruler, just like the one in that link!

ill be rotating the sprocket

I'm concerned about your chain length. What if you moved your tensioner forward of your rear tire? Could you do that, make your chain shorter and clear your chain stay?

When the angle after your tensioner down around your sprocket is drastic like that the chain has more leverage on the tensioner.

Took another look and it doesn't look good on the clearance. PM me and I'll send you a bracket for one of my tensioners.

rockvoice is right about flipping the sprocket over , so that the dished side is facing out. that will give you some clearance from your tire. thats what i had to do. the last two rear sprockets i got, did not have the dish in them.of course you still may need to add a spacer it that does'nt give you enough space.

You might consider making the engine side normal, or with very light tensioning. Or tightening it and putting the tensioner on the bike-chain side (I saw that somewhere...) I tried it. It worked. But I also tried a half link on my #41 chain and that lined both sides up perfectly, a light tenshioning, with the ghost sprocket was all that was needed.
I'm interested to see what you came up with for spacing.

Like wership says if you can clear your frame, run without tensioner. Use a half link, on either side, to get both chains to tension up with your wheel straight in the frame. BTW I love the ghost sprocket.

hey guys! im back in business!

i put some spacer on the wheel to clear the frame, and it worked like a charm.

now im noticing something...

the bike seems to be harder to pedal, and the clutch seems ok.
is it normal that the motor alters the pressure you need to apply?
also noticed something ive never seen before, the nexus hub protruding spring pusher, seeems to flip around...!!! got it off and tightened, but it happened again.

so im thiking the spacers i put on the hub are acting up with the hub...ill post some pics ones i get home



*ill post a thread on "hard to pedal"*

or maybe my bicycle chain is to tight...its pretty tight.....i can roll the bicycle back and forth if i press the clutch if that helps.
