the turbo underhead will add some efficiency and smoother power with a gain of rpm but its not something astronomical , btw with some underhead reshaping there can be more performance from the standard head button

if u didnt know the difference you wouldnt hardly be able to tell if you were running a plus 21-4 buggy or a plus 21-4T , now the team is completely different as are any of the btt series

Hey Monty,
I have a 21 CT and I've been having tuning issues with it mostly on the bottom end and won't hold the idle, and after inspecting the motor, I found the sleeve will just drop out of the crankcase, usually there tight, can this be the problem?
the motor has only 2 gallons on it, or do you need more info
thx

Is there really a market for that? Anyhow, itīs always fun with something new.
