Yea im gonna ebay those and my stockers and just buy a cub cylinder.

I will snap some pics of the pistons later today. I wish you could see the detail of the ports in the pics because there are some funny wear marks around that exhaust.

So would you vote on the run it and see what it does? Because im pretty sure they are to far gone to be cleaned up.

That was a read it wrong its 55mm wide and 34mm tall not 65mm . Bore is 65mm

its like 65mm wide and 42mm tall then like 74mm from bottom of the sleve to the bottom of the port. The intakes are 5mm wider than stock then dropped 2mm and raised 3mm then the port in the top of intake is 4mm wider and 2mm taller. if that makes sence The transfer ports seem to be 3mm wided and raised 2mm and quite large at the bottom

The exh port is huge! But I did get the old pistons with it and they are actually pretty clean with no scuffs or anything.

Well got the cylinders in my hands now and took some pics. Was going to send them off but they have had alot of work done on them so I think its going to be a waste of time. So I think im just going to try em out and see what they do, then if they bring the suck send off my stockers to get worked over. Anyway here are the pics.

Here is a pic of the bike,

I have a stock paint blue and white 1991 gsxr750 that the only mods are vance pipe and stage 3 jet kit. The bike runs and drives good but the tag is out of date. Needs a few items repaired but overall is a nice oil cooled gsxr. Would be interested in trading for a complete banshee or a decent blaster or other sport quads but would really like a banshee trade. Just let me know if you would like some pics. Also im located in central Oklahoma

Like I said got this stuff cheap, I got the cylinders with 65.0 795 wisecos a new in box hot rods 4mill long rod crank thats trued and welded, and a noss head without dones for 600. Figured it was a good deal since I planned on building a 4mill anyway. If the cylinders are to far gone I have a set of standard bores that came from my banshee that will get sent off for porting and fresh bore. This whole deal started when my nephews both got new Suzuki 450s and they wanna go to the dunes and all I have to ride anymore is a 600 grizzly. So I started looking for a banshee to build just to show them what an old 2 stroke can do but after I been on here reading I started to figure out its gonna take more than just a piped, headed, timed banshee to run with them. In my search for a builder banshee I found a 01 local that ran but had no power and backfired badly. Overall its in good shape and I liked the fact that the only mods to it was fatty head pipes so it was just what I was looking for at a price of 1k. After getting it home figured out the broblem to be a tore intake boot but I tore it down anyway in my quest for more power. So the plan is. 4mill stock cyl that runs on 50/50, 33mm-35mm carbs, cpi or shearer inframes, and a override trans ith lockup. I figure that with some good paddles and swinger should be able to do the trick.

Thanks for the help that was kinda what I figured, Least it was all fairly cheap. So I guess I will send it off to my porter and see what I can get done to it.

Been lurking around here for awhile (Great site bye the way) and had a Question about some parts i just picked up. The deal is I got these cylinders that are set up for a 4mill crank was told they make good power but im kinda suspect of the porting on them. Was told they made 80 wheel hp with fmf fattys, 35pwks, +4degree timing, at 145 psi. So im just wondering if this looks like a 80hp port job on a 4mill with those mods?
