On the 47/49cc Cag engines:
What's normal operating range? What's too hot?
Does anyone have an idea?
Thanks in advance!

Too hot would be when the engine seizes up .... :p

No, seriously, I know a few guys here are running temp gauges on their bikes. Hopefully someone will chime in real soon.

Normal operating range is 245 - 275 degrees.......

High operating range is 280 - 300....

Anything hotter than 305 is borderline dangerous to burning up pistons and seizures...

When breaking in engines I try to keep them in the 250-260 degree range.

I dont run a temp gauge............I use the point and aim infra-red types for both R/C and A/C...........
