Re: Zoombicycles 80cc slant head
i'm just sayin'. i've got a Grubee GT5 with the slant head, and i did the same thing to the motor that i do to all my bikes, and it's slower than all my GT4's with the flat head. there's another thread that's like 50 pages long, and if you read it, take notice of who's posting for and against it.
you'll find most (if not all) the experienced builders say it doesn't do anything for performance.
it may work just fine, but as a performance upgrade, no one's proved that it does anything at all, so in my opinion, unless you need one for clearance issues, save your 13 bucks and buy a 12 pack instead.
