good stuff buford, the ebay kit i got was a cheapie, my hoca head is machined beautifully.

[buford1488]

not too argue but machine in what way? there is no port work done at all. i have one of those hoca's just to see how they look.. and i am a machinist and i dont see anything that would be call'ed performance..just bigger valves then stock..but i would like to see a pic if anybody out there has any pics of the ports. sorry i aint buying it. there is nothing performance about it....

How much you charge to machine a head? I have tons of heads i could send you one to fix for me.

Hi, i just had the robotech 50mm bbk installed at the local scoot shop, i am brand new to scooting and would love it if ya'll could give some sugestions on what else to upgrade on it. I have a racing cdi and orange coil a have not put in yet...everything else is stock... it does 45 on the gps as is
