Chain/tire rub solution.

Made a chain guide using the stock chain roller and some 1" X 1/8" steel for the bracket.

Removed the bottom shock linkage for greasing and checked that the roller did not touch the airbox with the suspension compressed(see last pic).

That is kinda cool. Do you have any thoughts on the chain rub on the frame? Mine sure makes alot of noise on the frame.

I like it - that's nice work.

As far as the frame rub goes - make sure the master link plate/clip are on the tire side when you assemble and it's not so bad.

Not all 520 chains are the same width - the stock Regina chain has a 20.4mm pin width.

I'm working on that.

Never thought about flipping the master to the tire side, good idea. My bike came with a CZ brand chain, pin width on master link is 21.5mm, all others are 21mm. Any ideas on which aftermarket sealed ring type chain has the narrowest pin width?
EDIT: Found this= DID 520VT2 18.7mm pin width/8440lbs tensile strenght...DID 520ERV3 18.6mm/8660lbs. Could not find info for RK or EK chains.

what size rim and tire are you running?
IMO running a non O ring chain is the better answer, especially if you get frame rub.

Non "O" rings need a hella lot more maintenance and do not last nearly as long. They are good for MXers as they have less friction and those bikes are continually pulled down. For trail riders I do not think they are the best option.

OEM rim/tire size, 150/60-17 tire on a 17"X4.25" rim. Not sure I would trust a non-ringed standard chain on the street. Seems like a lot more lubing and it would still not be as durable. I could be wrong, before ringed/sealed chains were available, all street bikes ran standard type chains I guess.

and you get chain rub?
my SMR in stock form has about 1/4" clearance
and w/ a non O ring chain I can fit a 5" with a 165 Dunlop slick and it barely clears.

Im using a Renthal non O ring chain.
