Nick do you know how I can get ahold of Russ Collins?

Yosh. made 1148 pistons. I have an old GS 1100 "E" eng. in the barn, it has a set of 1148 Yosh pistons in it. Sorry, I don't remember the bore size. 1148 is pretty close to 1149.6

Hey rphillips did you see my pics? Anything look familiar? I'm grasping at straws here. I need any and all help!

[NICK!]

Yep, wouldn't be surprised then if it were a Yosh kit. Yosh quit making their own piston kits before I became a mechanic. Had a Rickman Kaw to restore in the early or mid 90's and it had a Yosh kit in it, we got lucky and they actually had a ring set left on the shelf, the last one for this wierd two ring Z motor kit. Give Yosh a holler, the worst thing they can say is no.

Here's Russ Collin's current web site, might be worth a phone call for no other reason than he was there and might remember something.

Here's Yosh's current website.

I'd suggest calling Vance and Hines but I really doubt they'd put you on the phone with anybody with gray hair.

I may be a little thick but is this your situation. You have a stock cylinder and aftermarket pistons. You bought Suzuki stock rings, pins and circlips. Your trying to figure if you can find rings, pins and circlips for the aftermarket pistons. You are going to machine your cylinders for the aftermarket pistons?
The pistons look like my Wiseco pistons. Flat top with valve clearances. Except my Wiseco pistons are 75mm. Stock are 72mm.

If you want to stay stock I have some stock pistons if you need them.

[rphillips]

Yeah, I saw the pics, but after 20 years, they all look the same. Mine started out at like 14 to 1 compression, & the tops had been cut down, to make them appx. 11 to 1. Worked pretty good for the st. but sorry I don't remember anything else. Contact Yosh. Maybe they can help.

[NICK!]

OK, here's a big surprise to me, Orient Express is still in business and they were big time around in the day of your engine, I'd call them first.

No Chef, my cylinders and pistons are the same. I just dont know what I'm going to need for rings and pins! I've never dealt with anything other than stock. The measurements mean nothing to me and I dont know what I need or where to get it. Thanks

[ghainjr1]

I took some more measurements and the best I can come up with is that the cylinders and the pistons are 75mm give or take. I took the measurement from the bottom of the piston.

[chef1366]

If the pistons are 75mm you have a 1166 wiseco kit

[ghainjr1]

I was also told that its an 1166. Wiseco has the only 1166 or could it be from someone else? I dont know,thats why I'm asking. Thanks guys. Greg

[chef1366]

Here is pics of my 1166 build in progress.
If they are indeed Wiseco you can buy rings, pins and circlips. Only use Wiseco circlips for Wiseco pistons.http://www.wiseco.com/PDFs/Catalogs/...etOverbore.pdf

Not sure if they are Wiseco brand. I know Ape sells a 1168 kit.http://gszone.biz/enginekits.html

[ghainjr1]

Those look like my pistons. Do you have or can post anymore pics? It would be great to be able to order what I need. Thank you, Greg

I cant tell from the picture, are they flat or is there a slight dome?
