It,s only one tooth mate. OK as long as the spindle isn,t right at the front of the swingarm slots. Why 520 chain and sprox? Saving weight?
15/44 should work fine with stock length chain. I have 16/44 with stock length and it fits, but only just.
Brill - delivered today, struggled to get the mrs to dine valentine style in the garage tnite so I could fit! Read the 'hype / comments' re 520 & simply thought I'd try as I feel I've bought some quality kit and saved a few quid by going 520, in purchase price anyway. I'm not too worried about wear n tear, great to have new n shiny bits now and again! She's (2011 HRC) coming together now, hopefully not over-doing mods, just tastefully making her mine. Hope to post pics soon, see wot ya all think!
