Rpm's ????

[brydonb]

So how do you know how to get the optimal amount of rpm's out of your 80cc chinese engine? Is there anyway that a person could tell? (tools, or any other kinda tricks). I finally have my bike running well and all bolted up nice and I would like to dial in my rpm's. Thanks in advance for everyones input and advice. ROCK ON

Google TinyTach, you can buy one for about $35.

do you know the correct rpm's for the 80cc?

Safe RPM post recently and there was one even more recent with a different tack listed. They were both just around $35.00 to buy.
Trek 4500/ GEBE w/ GP460 build post also lists a different Tach.

The powerband on the 67cc motor is between 4 and 6 thousand RPM

hi; the more you wring out of a chinese engine the sooner you will buy a tanaka-honda-subaru and fugetaboutit. mitch
