STS 21E
Hi, I just broken in STS 21E engine on my buggy and during race tune I I can feel the speed and also smoke out of the pipe but I check for the temp it only show 80C - 90C. I am worry the low temp might kill the pinch as the sleeve not really expand. I need advise do I need to lean it more to make it till ~100C? My country weather is around 33C. Thanks.

Here in sunny Singapore,we run the STS at almost 120C and still have decent smoke trails.I have run the STS 21,28 and the 30.These mills are cheap bang for the buck engines.They are strong and powerful.Downside are that they don't last and needs warming up before they are good to go.Penang is similar in climate to Singapore.My suggestion is that you can lean it down a little more.
