2nd Build

[jmr3394]

So for my second build i have decided to go with a 66cc 2 stroke paired with a 50 tooth sprocket. The bike will be mostly used at school where it's kinda hilly. Did i make the right decisions? Please comment and/or criticize....

Sounds good to me. Here is my 66 with 44t going up a 9,000 ft mountain.

How fast will i be able to go?

Unless you weigh 300lbs, I would stick with the stock 44t sprocket! (It will pull you up most big hills without any problem.)

i have a 44 tooth now and the fastest i can get up a hill is 12 mph...

Even with a larger sprocket, you won't go faster up the hills!! It will just be easier on the engine, (& you will also go slower back down the hill & on the flat.)

agreed......I have a 41T on my 66cc bike and I weigh about 200lbs I run up most all the hills around here at 20-25+MPH and still about 16 -18+ on the steeper ones, it will just chug right along to the top and then I can still cruise nice at 30mph.
