Wink Vortex 18 tooth sprocket

I know a lot of this has been covered in another thread, but this might save some of the USA guys from having to call a bunch of different places like I did. I called several different vendors, but no one knew anything until I called Vortex. Based on the info trickytruckertrev and titters posted in other threads (thanks guys!), a guy at Vortex quickly figured out what the correct part number was.

The correct sprocket is the Vortex 2910-18. It is a 525 sprocket....it has the correct splines, and does require the use of the washer/spacer under the counter shaft nut. Installation took me about 1.5 hrs since I haven't done it on this bike before, now that I have done it once it will be much quicker next time.

I needed a 36mm socket for the axle nut, a 1 1/4" (27mm?) for the sprocket nut, a 10mm and 12mm wrench for the chain adjusters, and an 8mm for the counter shaft cover bolts. You must first undo the clutch cable before the cover can be removed. As expected the counter shaft nut was pretty tight, but no worse than any other bike I've worked on.

I did sneak in a quick 10 mile test ride last night, and am quite pleased with the results. I haven't ridden far/fast enough yet to determine it I want to go down a tooth or two on the rear sprocket. I intend to go on a 3500-4000 mile ride out west later this year, hence my desire reduce engine rpm at highway speeds.
I hope this helps someone in the future!

Awesome, I couldn't locate a 525 18t sprocket via online page. So how does it pull vs 17t?

I'm sure there is a minor difference, but I really can't tell in my two brief test rides.....it still pulls very hard in my opinion.

Hey Denver, did you notice any increase in chain noise not having the rubber dampers on the sprocket?

Is the washer/spacer something you have to purchase additionally?

No extra parts needed other than the 18t sprocket itself. I don't notice any more noise then before, it may acutally be a little quieter even, guessing due to the chain going around a slightly larger radius maybe? Everything was still pretty new when I did this, so it could get louder as things wear. I think its been on the bike for about 4,500-5,000 miles at this point.

Thanks Denver, great info! Did you remove one link from the chain? Gearing Commander shows a better wear pattern with 115 links versus the stock 116 with 18 tooth front

I didn't do anything to the chain, but I think its long enough that you could remove a link if you wanted too.

Stock is 17 tooth so going up to an 18 you would need a longer chain if anything. Apparently there's enough room on the rear axle adjuster to compensate.
