I can Vouch for the 5 port.....
I have an XB8 EC and a NEW Modded Go 5 port and HOLY cow its a really good engine.
There is a new batch now which apparently has a new carb and LSN needle. Make sure your supplier has fresh stock.
They are only getting better.
Cant wait to really get some time on this baby.
In the Truggys with a 2047 pipe they rip up the tyres no worries, BIG BALOONS.
Another Plus for Go techers is the excellent 10 min tank times. Power is no good without effieciency.
I took a gamble on this motor and wont look back.
