Which one!!

i started out with a 36. it worked great for me, but i'm 135lbs. pulled hills fine, ran great.

i'm now running a 32, and it's fine for me too. a little sluggish going up hill, but there's not many hills where i ride. on a long straight, i'm hitting 40-43mph. cruises 35 easy. not too bad off the line, either, and it cruises through slow parking lots no problem. maybe i just got a super-deluxe special engine, 'cause everyone else is gonna tell you different.

my 24" rustoration bike i'm building is gonna have a 30 to start with. i've got a 28, too, but that's about the limit. any smaller and there's no clearance between the wheel, the hub and the chain without doing crazy mods.

my 26" seems pretty maxed out as far as gearing goes. anything lower is gonna bog up hills, and take a long time to get up to speed.

a 28 would work great at bonneville, though. you'd have plenty of time to get to top speed.

I've run 36T's on a few bikes, they're really fast going down the road but (for me) they really lack power getting up to speed & going up hills. (I weigh around 195 lbs)

I'm really into the 40T sprockets these days!! It gives just a little more top speed, it cuts down the engine RPM's @ WOT, (the engines don't feel like they will blow up from over reving now), & I still have plenty of power & torque for hills!

I agree with Venice,
I have tried 32, 36, 40, 44, 48, and 50 tooth when running my 2stroke
the 40 is the best compromise between low-end torque, and high-end speed

hey i got the chain the only thing you are going to need a master link so it you want to meet some where or come get it just let me know
