Well, my TBS has just over 12,000 and the chain is to the end of it's adjustment (yea, I need to check the valves too..)
So, new chain time. I was thinking RK or DID or something good.. if I'm gonna spend the money I want it to last awhile.
I've been looking at sprockets, and I have found that Renthal lists some specifically for the model. I have found the mfor sale on kneedragger.com, but they only have 40t, 43t (stock) and 46t rears. They do have 17t (stock) 18t, and 19t fronts.
I was thinking of going with an 18t up front, to get the chain up off the rubber guide (which, of course is trashed and will be replaced) however I want to lower the gearing if anything, not raise it. Just to keep the gearing near stock, I would have to run the 46t. That's actaully a 2.56 ratio vs the 2.53 (43t/17t) stock so it's 0.03 larger, but I don't think that's much.
Also, I've read about how it's best to use odd toothed sprockets, or at least one. Worst of all being two even number of teeth on each as it dramatically lowers the number of full chain rotations it takes before the same link and tooth contact one another, which is what causes the most wear, in theory at least. So, in conclusion, I was thinking of keeping the 17t for gearing (probably the triumph stock part for fitment) and going with a 45t rear.
I was wondering if there were any other manufactures you folks are aware of, and/or places to get sprockets? Also, any awareness of interchangability of sprockets that might only be listed for other bikes, but work perfectly fine? Say, bonnie, thruxton? I know there are 520 conversions out there for them as well, so that would be cool. Maybe ZRX sprockets? I know they share some similarities of design, and other parts are simple bolt-on swaps..
I have read the webbikeworld.com TBS article on chain replacement, and actaully the author steps up to a 45t sprocket on the rear, and gets it from JT. However, I have been having trouble finding them on the web, besides their homepage, which is about as informative as smoke signals.
