Hello from the UK, as you may be aware we don't get the Banshee here so my plan to build a 421cc 4 mm cub motor for a street bike is not so easy. I have a pal in California who is going to let me have a short engine just for the cost of shipping and will ship a kit to build the rest with it if I get it sent to him.
What I need is a one stop shop for the whole kit so I am after recommendations for an outfit who can do that. I've tried a couple just searching the internet, one tells me I need porting work done and a single carb, another I tried has bad bad reviews once you start looking so I need some help here.
I'll be getting a frame made and using it as a street bike so need some reliability/rideabilty, I'm quite happy to build the motor myself, I know the RZ motor reasonably well. From looking for info online I'm fairly sure of the parts I need based on the Serval cub jugs probably running twin carbs. Any advice welcome though on components/set up but what I'm really after is a reliable supplier who will sell me what I need as a complete kit and not rip me off.
