So I just got around to doing the 6,000 mile / 1 year maintenance on my Bonnie, and I'd gone to a lot of trouble to get what I need for adjusting the chain, only to discover upon measuring that it only deflects 1 1/8 inch, which is within spec. Is that strange? It seems hard to believe that after roughly 6,000 miles my chain is still within spec. I measured total deflection, from top to bottom, centering the measurement on one of the chain's pins, using a ruler that I stood up against the ground.

Is that normal? Not that I'm complaining, but it's surprising to me.

That is normal. Chains these days are very high quality

To quote myself .... from 20 threads down the page ...

"I have just come back from a 1900 mile tour and the chain only needs a clean not an adjust!

The bike has done over 25,000km (15,000 miles) now and has only been adjusted 6 times, it is still only half way through the first notch on the adjuster."

+ 1 Chains today ("O" ring and "X" ring) are far superior to those of a few decades ago. Seems that they go a long time between adjustments. Aside from lack of lubrication and grit what kills a chain is abuse such as burnouts.

Mine has taken almost no adjustment in 8500 miles.

Believe me, this (and thoughts of a broken chain destroying my cases, my legs, etc....) is why I spent $500 and a half-dozen hours of my life (not entirely because I'm inept, although that IS a contributing factor - the whole primary has to come off....God bless the Queen....) converting my 530 plain chain Norton Commando to a 520 x-ring.... Count yer blessings. - BrianK

Maybe...but it sure is fun to do

NortonBrian, sorry if this is a dumb question, but couldn't you just put a 530 x-ring chain on that Norton? Or is there more to it than that?

A very logical question, to which the answer is: Unfortunately, a 530 x- (or o-) ring chain is too "wide" to fit the bike. A 520 x-ring is about the same width as a 530 no-ring, so it fits. But it necessitates changing sprockets - and the Norton rear sprocket is an integral part of the whole brake drum assembly, and the entire primary has to come off to change the front sprocket. So it's pricey and a bit of work.

But I had the Snorter out today for the first time in a few months and it was glorious! Started on the third kick (pretty good for sitting three months or so with Stabil in the tank) and ran beautifully. Went out for a quick ride around the block, came back 35 miles later, frozen to the core (didn't really dress for the weather since I was only goin' 'round the block....).

I never said it wasn't fun! Probably only second to throttle wheelies. ;-)
