Hey forum!
I was wondering about this for some time now. Let's say, there's a 2 stroke that revs to 6000 RPM, and has 2ft lbs of torque. It's max speed is 30MPH, with a 44 tooth sprocket. (I'm not saying that those are my specs, I just made that up.)
What would be better for reaching more top speed?
Porting the engine, to reach a higher RPM, let's say 9000, but could be any number, at the expense of losing 0.2-0.4 ft lbs of torque
OR
Upgrading/modding the engine, so it has the same max RPM, but let's say 0.5-1 ft lbs of torque, and using a smaller rear sprocket? What's more efficient?
I'm not planning on doing any of theese, I don't feel too safe riding at more than 30MPH. I'm just asking, and someone may want to do that.
