if you want the most power with little cost go with a 7mm. get it ported and run the pistons into the domes. its not much more than a 4mm. crank will run a little more and you have to add the price of trenching the cases. but the power gains are more worth the money for a 7. sell the t5's go with better pipes like cpi.
when i am not tearing it up on my banshee i am doing motor work on other peoples banshees. guess i cant stay away from them. my garage is full of bikes i am working on. time to open up for the general public. maybe make some money off this sport.
westexgt just shipped me a motor from texas to seattle and it cost about 65 to ship through ups. he wraped the motor with bubble wrap and then put pillows around it. it showed up in perfect shape.
get someone to make you a subframe. it will look better. just bend the other back. or buy a new frame. i hit a sandrail doing 45+ last summer with my banshee, want to try and staighten that frame?? looks like a banana. also for sale
i run 40:1. and its still a mess when i tore it down, lots of oil everywhere, you should be breaking in your motor with the mix ratio you are normally going to use.
hey mooney your 4mm gas bike was running in the 5's. you never hit a 4 anything yet. but your right about the gas 350's there are a few running 4.5-4.7.
