So I purchased a 520 17/44 chain and sprocket kit.

how many links long should it be and how much deflection should I have on the chain once it鈥檚 adjusted properly?

thanks in advance馃檹馃徑

I set the chain tension with my weight on the bike. Just enough slack so chain just clears the bottom of the chain rub gaurd on the lower side of the swing arm.

definitely did!

also with the front sprocket, which side should be facing out? Depending on which side is facing out, the chain can be misaligned because one side has a longer collar.

Looks like I did big side out--I'm sure I reasearched it at the time. If you think about it if the collier is the same as normal but the sprocket is thinner it would go that way.

The old owner's manuals used to say, 'Have a buddy of about your weight sit on the bike while you make chain adjustments'..
I'm runnin 17/42 and 112 is the number for that
How do y'all keep em so clean??

I put my weight on the bike by lying across the seat.
Also when sitting I can reach down with my left hand and have a feel...

She鈥檚 she鈥檚 running great.
I have a bit of vibration starting at about 160kmh. Could be rear wheel alignment?
both tires are new.
Maybe rear wheel balancing is off?
if the wheel was bent wouldn鈥檛 I notice it at a lower speed?

So the mysterious noise is magically gone?

What is the frequency of the vibration?
My guess is high.
And likely not wheel balance related.
Look at the sides of the teeth on your rear sprocket for any indications of wear.
Ditto the insides of the side plates of the chain.

Where do you feel the vibration? Left hand foot peg?

So I think I can chalk it up to shitty pavement and a windy day because it seems to have gone away.
While I had it up on the stands I also did a front/rear wheel alignment with some string and stands. That May of helped a bit too馃し馃徎鈥嶁檪锔

I have found with my bike if the chain alignment is even slightly off I get vibration at speed, most noticeable on the left hand side.
