what about red line

does 30mm exhaust and 44mm transfer ports sound right for a stock cylinder? when i grind down to 26.78 on th exhaust do i also remove the same on the bottom of the exhaust port? ive already cleaned up casting flaws and sharened up the the transfer port ways. now what size dome would work good with the cool head 110 gas 35mm carbs, cpi and this port work also what would you set your timing plate at? thanks.

one more thing on my other set of cylinders the intake is hogged out almost 6mm higher than stock with 3.5mm holes drilled on the sides will that be the same on my cylinders?

great thank you so much.

cpi in frame pipes, all out riding all the time. mostly weekend hill climing and some trail riding all on soft oregon sand.my budy has a stock stroke banshee with a full drag port and cpi pipes he says he is running at about 75 hp i want more than that.

as soon as i figure out how. the yfz 450 front end fit good i only had to move one mount on the lower a arm and 1/8th " over on the shock mount

i ported my stock stroke banshee already and it runs grate its only for my 16 year old daughter so i didn't go to radical. and I've been told you cant use a stock port on a 4mm i have all the tools and i have a good know how. i just don't know about the 4mm. im looking for the numbers. thanks

hey there every one I'm new to this. I'm moving from 450's to banshees my daughter has a banshee and now i have one. i used to have a yfz 450 before i blew it up, since then Ive taken all the good 450 parts and put what i could on my banshee, 450 front end that widened me almost 6" in the front all custom paint and i did it all. i love my quad and it came to me in a box and I'm having fun making it mine. i have a 4mm crank, 35mm carbs, stock cylinders, stock head all brand new. i wont to port and polish full race port polish. my lower end has already been done now i need some feed back on spects maybe pictures or someone to talk to that isn't trying yo make money because this is something i will do my self. so if any one has info please send it my way.
