Are you sure about that Buku pipe? I've heard some good things, some that say its a BS waste of time. I have a Dynamite 053,
$50 from Barnstomers ( RCM home track.) Great price and fast shipping. Check out is a bit fiddly tho. lol
I have it w/ my lrp .28 and it does well. No standing backflips, but I don't aggressively tune it. Does pull midrange wheelies tho. Nice motor and easy to tune.
