15 front 43 rear

haven't done it yet, but as soon as i can it will be done because i was looking at y chain today and i can see where a rivet is about to come.....bummer i was going to ride today..........it's south Ga here weather is perfect.

 

Don't bother with an alluminum sprocket, go with steel. The vortex alum sprocket that I had lasted about 4K miles and it was DONE.

 

Agreed - I always use steel, even on my dirtbikes.....aluminum rear sprockets wear out too fast.....

Consensus (so far) seems to be to opt for more zip (drop a tooth up front) and less top end (add a tooth or teeth in the rear).......makes sense.......I dont need to go over 100mph anymore (my track days are behind me)......and the front end will feel even lighter with one tooth less up front......not sure why I haven't screwed around with sprocket sizes before now (~39K miles on the bike!).....I change'em up all the time on my dirt bikes....

Has anyone used aftermarket cush drive blocks in their hubs? (Not sure if there even is such a thing but thought I'd ask.....)

 

I have a set of sprockets from sidewinder. The trimetal rear with the steel front. I wouldn't get the trimetal again, but the full titanium rear will give excellent life. I did not like their chain at all, so substitute with whatever. I have gone through two chains with that set of sprocket and it doesn't seem to wear very much.

 

Shorter gearing doesn't really even affect top end. The Superhawk stock will go faster in 5th than in 6th. It's a win/win with shorter gearing if you can stand the extra revs and buzziness.
