I have a SH .28 and running a stock pipe. Ive been thinking of upgrading to a better pipe and wondering if any one has any thoughts. I like the JP, either 1 or 2.
BTW, would you say the SH .28 is more of a low end or top end motor? Whats temps are you running yours at in 60-80 degree weather?

I also need to buy a back plate so I can remove my pull start. Any suggestions on where to buy?

I have just broke mine in and really like the power and how easy it is to tune. Great motor!

Ive posted in the engine section, but there is not much traffic in there.

The JP3 (balanced power) is probably best suited to someone who isn't racing, and the SH28 is pretty balanced for a .28, but most .28's are bottom end engines anyway compared to .21's.

JP3 is more suited to balance top and low end power.
