epyc421cc

Hey guys I am turning my 421 stroker cub that runs currently on c12 110 octane to run on pump gas...bought it set up this way and dont wanna be paying the price for the fuel...am gonna be riding dirt roads...pitsand hill climbing...what is the best head/dome cc, carbs, jet size, timing,....everything...

Awesome thanks for the info...I had intendedit use more on open back roads pitsand hill climbs...not so much theracing..

Not sure what size the carbs are and im away from it right now...race gas is too expensive lol...19L (5gallons) is 145$...c12 110 octane...I was told I could run a couple bottles of octane boost to get supreme gas to 105 or something but not sure...

T5's or somethin..I was thinkin about puttin a 2 in a carb on it and diff pipes for more bottom end when I swap...

Nice...I had thought about selling motor complete but it was the 421 stroker that I wanted...will still put out alot more power than just the stock 350...

Always wanted a banshee never had one or any two stroke for that matter...it was a trade off for my 05 crf450r...I know ill lose about 8-10hp swapping over...im in for a big learning curve lol

Do the jets need to be replac3d and timing and what not?..

Hey guys I just got a 421cc stroker banshee that runs on c12 race fuel...now I wanna put it back to gas so I am wondering what size head I need for it...will a stock head work or should I get the 421 head?..and what dome cc sizes as well...my compression seems fairly low for race fuel bike at 150psi...iv heard they should be any where from 160-200...bike runs great...but I am a little lost in what to do for the swap...I am not sure what the dome size in it right now is...
