I need to replace my rear chain & it's been years since I looked into them. Any suggestions on witch are good? I don't want to get into mods for X or O ring chains. Just want to know witch ones will give me the least trouble with clearance but I want to buy a top quality chain. "Life is to short for junk parts".Thanks.
Rear drive chain, Reynolds, Regina , Diamond???

If it lasted 10 years, you want the same kind as you had, again!

I don't think you will go wrong with any name brand.
Where i have had clearance issues it has only been the spring clip type joining link - the pins on these are generally longer than on the rest of the chain and more so on some brands than others. The tips of the pins on the joining link can be ground down a little without losing the groove the clip sits in.
Also try mounting the link with the clip first on one side then the other to see if one way has better clearance.

Don't put the clip on the side that has clearance problems.
Hi gtsun,
I know you said that you do not want to do the "O" ring mod, BUT if you are going to do the job properly you are going to need to replace the front and rear sprockets anyway. So, you might just as well purchase the 520 size sprockets and 520 "O" ring chain, you'll be glad you did.
The Norton Atlas front sprockets fit right on and are 520 size, and I believe the 520 rear sprocket is available from various sources (try http://www.clubmanracing.com). In my experience "O" ring chains last twice as long as standard chains with less mess and adjustment.

PS. I just checked clubman racing and yes they have both sprockets in 520 size ($180 for the rear)

Chain manufacturers often rate their products by yield tension, an unambiguous standard that doesn't really tell you if the chain is suitable for your bike, but offers a means of comparing different chains. Higher tension is better. During my Mk3 rebuild I fitted a Tsubaki 530 with a healthy 9800-pound tension rating and simply got lucky, as I now understand that the Mk3 has a bit more room for chain clearance than earlier models (this came from either Les or Ron on this forum). Tsubaki rates this chain for 750cc bikes, but keep in mind that modern bikes of this displacement generate more than 90 BHP, and our bikes are doing only half of that. So I suspect that these heavy duty chains are overkill by a factor 2 or so for Nortons. I'll continue to run Tsubakis since I've got the room and they are lovely to look at. Fred at Old Britts sells generic black chains for a third of the cost of a Tsubaki, and I would trust his judgement on their suitability for Nortons.
