Thanks for the spanking. If you read my post you'll see I ordered it before I read the bad comments about the sprocket on this forum. How old are you?

Okay, so I just did a 15 mile test ride both in town and out in the country at speeds up to a hundred and ten miles an hour. I can perceive no change in sound or noises or vibration. A six and a half percent gearing change is relatively subtle, but it does mean in 5th gear instead of being a hundred and five miles an hour you're probably a hundred and twelve, which it still pulls easily even though I'm the size of a small bear at six foot four 350 lb. With a helmet on, and being 60 years old, it could be I'm just not hearing it. I also only had eight hundred and twenty miles on the bike at the time of the sprocket change so the chain was still pretty fresh. I installed the sprocket with the writing facing out, and torqued it to 108 foot pounds. I made sure the axle was straight and put 1 and 1/2 inches of slack in the chain. For now I'm happy

Glad it worked out for you!

"We've installed many aftermarket sprockets on various bikes and they all have that noise.  Some, more than others."
Who is we?

Gearing change done. 15 to 16, feels better and seems no change in speedometer reading according to the road-side radar thing. Indicated 70 is right on 4000rpm. I spaced what the reading was before so anyone riding soon please note rpm at 70. Getting the countershaft nut off needed a strong air impact so you may need to go to a tire shop or someplace. Does not feel like it zips right into 6th now and less sense of looking for 7th but plenty of acceleration still of course. I'm pleased!
thinking of doing this mod .. is the thread left or right handed , cheers Luke

Jt sprockets are known to have issues on the RS. Pay a few bucks more and get the OEM
