M-8 107 Big Bore

[Tattoo]

Hey guys I know its been awhile we got hit hard with HD EPA BS and had to lay low for awhile. So on the M-8 107"  how big can you bore the stock cylinders without cutting the cases?   

Thanks...   WES

I believe 120 with different cylinders and no case mods.

what about stock cylinders?

Fuel Moto is doing 117" with stock cylinders.

EPA came down on dealerships too? Jeez.

107 to  120 may require  a 4.5 set of wheels

I think it goes to 124 with 4.5 wheels.

I'm doing a 117 from a 107 but i think you can go 120.

I would be afraid to go 124 but hey  people do it

I'm in the process of going from 107" to 117"  The plan is to bore a set of SE 114" cylinders I got for cheap on Black Friday which will leave a little thicker cylinder spigot. Picked up a set of the Wiseco Black Edition 11:1 pistons and Cometic .030 Head gaskets.  Still need to buy an exhaust and waiting for Cycle Rama to come out with a cam for the larger cu engines Not sure if the Bandit clutch I already had is the way to go or not.

Started one today, using Suburban 120 kit with Mahle pistons. Thinking I'm going to let Wes @ Cyclerama do the heads along with a new cam he is working on.
