Hi everyone , first time out on my fresh GP rebuild jet barrel yam piston reed valve by Harry Barlow , running 30mm pbh and avanti ST .
with a static vape @ 18 btdc
I have CHT threaded in the CH , on first ride it was running at 171C which I thought was danger hot .
any one go a similar set up that could give me a safe running temperature, that i can use a bench mark before i start changing carb settings.
tks in advance
and KTF
