No phantom no problem... These are expensive... But if I'm going to gamble on a cylinder the moped junk has been around and proven... The pFlantom...
The gilla is going to want a $300 pipe and the carb... Unobtainium NOS head but they're around... The Air cooled cylinders I think are the way to go... 47mm so it's not so over square... The fan cooled cylinders will have more power and liquid even more for those reasons... So it's adding liquid or free air head... but on the cylinder there made for a fan blowing on them and at a certain amount... So you can widen the ring gap take a few thousandths off the piston above the top ring. Then drill 3 .25 mm holes inline with the ring pin spaced out evenly... Your going to need the highest quality top end bearing and weisco or malosi pin same thing on the bottom end but a crowded bearing on a wieisco or (there's a wrist pin for something 16mm for an automotive application you have to cut down...) grugden pin put together with shims... Just like the bottom ends on the bikes the cylinder is made for...
I thought about trimming the cooling fins off of a 110 lemon cylinder with a Dremel cut off tool and muggy weld with fine low temp muggy
sticks with pookie pipe lighter with a wet rag in the cylinder and fit the phantom with free air cylinder fins... 52mm to 52mm just a lot of work...
I thought about wrapping up the cylinder with copper pipe and plumbing it in with a transmission cooler for a convection system... Like my old Johny popper bulldozer had... Cutting the top off it and useing a CNC head for a LD 100 on the saw cylinder or jog 90... It adds up quickly... $2000 in cylinders to try that somebody at some point used and there's a thread with a twist about it...
What I'm doing after my 10 year vacation from motorbikes is get caught up on the stuff that I would have been doing if I wasn't building a 60's to 70 Mopar... A 4 door but something Richard Petty wouldn't want to get out of if he seen it but with a 315 LA with 375hp @12k ... 70 k member with caltrack in the back... Old school cone Shure grip with 294 gears so it liked 3 gear on the highway but 1/2 would sling you around an auto cross... She really shined going up I95 at about 4 grand... 120 needle just buried... Just a little bounce... Then lay about a quarter mile of rubber till it hit about 180 then is squirly like a shopping cart and is got just enough gas to coast to the next gas station... I could burn 10 gallons going from a stop and getting to 100 not even pushing it... It held 45 gallons between 4 fuel tanks.. one in the front and back 2 along the rockers.. each had there own pump and return... The fuel line held another 8 or so... I could switch between front or back or rockers with a solinoid on each sway bar end link... Lot of repop hemi suspension hardware...
Then it was disassembled and boxed up into a connex and shipped to the customer... I drove it mabe 10 times... Sadly I lost a lot of pictures and paperwork for it ... For B bodies only.. Sleepar was my handle 2014- 2016... Till I got banned
