Choosing a Rear Sprocket

I'd like to know your experiences on 36T vs 32T rear sprockets. I'm looking at going to a smaller one. I have a stock 80cc on my MTB. There are some hills around here but it's mostly flat. I's like to keep up with most traffic around here (35mph), but the question is will the 32T be able to pull my 120Lbs or should I stick with the 36T? Any body with practical experience with the two please chime in.

I will only say that you should stick with the 36T since the engine will not like pull you with a 32T. It barely pulls with a 36.

1+ bike guy...most people recomend 40t as a happy medium between torque and speed...120 pounds is so light!!! my MB is 280 and i can go 22 mph with a 44T.....i bet a 40t will give me 25 easy!

...my left leg weighs 120#...OK, my left leg and arm.

There is a big difference between the stock 44 and a 36, going to a 32 is pretty high.
I'd say 125 pound rider and good smooth tires, no hills it would be O.K., but the engine will be dogging at anything below 25 and it still won't go much faster than 40-ish.

I just purchased a 36T from BGF with extra rag set (inc bracket and bolts) for 19.99 + $10 SH. I think the 36 should to it. Next I'll look at a larger carb jet and/or expansion muffler. But I really think I'll wait until i have my rotor brakes ordered and installed.

When I designed my CNC 3 way mount sprocket I settled on 35 teeth
as the best compromise.......

44 tooth = 27.9 MPH at 6500 RPM and 26" tires
35 tooth = 35 MPH at 6500 RPM and 26" tires

35 tooth at 5000 RPM = 27 MPH
35 tooth at 5500 RPM = 29.6 MPH
35 tooth at 6500 RPM = 35 MPH
35 tooth at 7300 RPM = 39.3 MPH (~True redline on a stock 66 cc)

The Chinese 66cc 2 stroke engine does not have enough power to
pull a smaller sprocket than this without losing a lot of bottom end
and it won't go over 40 mph anyway cause it doesn't have enough HP

Speed is not the only issue with a smaller sprocket as you are dropping
1300 RPM at 28 MPH for a much smoother and comfortable cruise

My sprocket mounts with the small Grubee style rag joints and has
a larger center hole diameter of 1 11/16" that matches the rubber rings

It also mounts with the larger diameter PK / Raw rag joints or
can be Clamshell mounted by the large 3 holes

Reversible offset mount 1/4" thick light weight aluminum 7075

PS: My CNC 35 tooth sprocket is 0.8 mph faster than your flat? heavy
steel 36 tooth BGF which has badly formed teeth

im hitting 35mph with my 44t sprocket so i guess i wont change anything.

If that was true you would be at 8150 RPM with 26" wheels

How are you measuring that 35 mph?
