Random cylinders

[Canada]

Hi, im looking at a banshee that is a total baskit case, but has a few nicer parts pipes, carbs, tires....

The strange thing is the cylinders, its a one part jug like a cpi cub/serval/wampus, but it has 6 bolt dimond shape reed intakes, and a open large volume coolant flow like with a o ring head, 10 stud head

What could this be, it dose look like it belongs with all the other parts like carbs/reeds .....

Cheetah.. they use a 250r Reed cage

[Canada]

That would be great if they where, Based on the 250r reeds thats what i thought, But im not so sure yet.

Its just the big very open water channels, and rectangular head that has me wandering

Wish i could post pics, but maybe it could be some old school cheetah?

[JUSTWANNARACE]

If it is rectangular than it is probably an LA Sleeve cyl they used 250r reeds also

[JUSTWANNARACE]

Can you get a pic?

[Canada]

Wow your good, thats it! the LA sleeve just looked it up, wow 1900 usd

Are they any good, aka worth a re nik if need

My current banshee is a 421 serval

[JUSTWANNARACE]

They take a ton of port work to run well but the do run decent once worked over. Are they going to out perform your serval, no probably not. But not a bad cyl by no means, better than stock for sure.

Thanks Justwanarace thats good to know, as there is like no info on them like a youtube video or anything. I hope i can still get replacment parts for it as i just made a deal on it.

[JUSTWANNARACE]

You can. LA Sleeve will have parts. ESR, NIX and Pro X are all the same LA Sleeve cyl

Great news i just got everything blown apart and the cylinder is mint reeds are good too.

The cast piston's on was cracked and the coating worn off, the other is missing a chunk where the same cracks formed

The bigger problem is i can get the blown pistons wrist pin out, even with heating the piston with a hand tortch?

Whats the best way to cut it off without damaging the con rod?

[Canada]

The one piston was totally normal just pushed the pin out, the other feels kinda notchy but the rod with side force can slide around a bit but the pin is frozen, the main crank turns nice and the big end of the rods feel smooth with no play 

I got the cases split, but i forgot about the stuck wrist pin so i cant get it apart with the piston in the way

i got the frozen pin to move a few a few mm either way but its very stuck like the needle bearings are hung up in a groove

Ok cool i just ordered one now for a bit less, but it come with only two size 14mm-17mm

Either way till it shows up this will be my last two question

#1 if the bore is mint, can i just switch to wisecos forged pistons same size 68mm and re-bore to that

#2 if i can do that are these the standard blaster 68mm pistons same used on the cub? 

la sleeve is asking $75 for the gaskit kit thats ok , but 200 something for the pistons in cast
