Ok, so I finally got my tachometer on and have been watching my RPMs for a few days while riding around.
I generally cruise at around 20mph give or take. I've been finding that 22 has been the sweet spot lately.
Now, watching my RPMs, it looks like that at 22mph, i'm turning around 6,000 RPM. Is this safe long term for my 70cc HT engine or should I drop down a few sprocket sizes to get the rpms lower? I have no idea what safe redline RPM is for this engine. On a couple brief blasts, I've touched 6400rpm with it, which seemed way too high to be running the engine at.
I'm currently running a 48T drive sprocket. I have 44T and 36T on hand if needed.
