Dave I'll buy that if still available

You mite run into the timing number not being the same

I think you will run into a problem on the wrist pin size with the go if you use the os rod and crank pin size and maybe length if you use the go rod.

I wanted to apologize to Dave and Mike for making their life hard on this. I realized that night later It was just not worth it to try what I wanted. I will just keep a look out for a cylinder for the second engine and go from there. I would really like to find the rz-m like I have in one of my boats its the same as the rg just pipe timed. I just need to stay with the short stroke of the older motors. Again I really appreciate your guys time and again sorry about all of the trouble.

I asked alan today since I saw he bought some parts from brad last year when he sold all his stuff he had a couple of good used rz sleeves he sold him . I havent heard back but yes keep me in mind I might take my rz inboard and degree wheel it pull the sleeve and if I have to match the new rg sleeves to the rz timing and shape. I was going to resell that new rg motor since it cost so much but I might have to use it if I cant find anything.
Also today I made a mandrel and spun a old picco sleeve down and I think I can machine it down myself I was able to use a good Nicholson file and a drill and a good sharp chisel followed by a knife wet stone set and was able to get the size and finish and make it true pretty much just had to take my time. in the end I was able to take .5mm off the lip and .5 off the main body without trashing it .so I might try on a good sleeve I am just nervous still to do it . I would hate to mess one up .

Do you not have a lathe yourself or even access to one? What you need in photo isn't good enough at all, just my 2 cents here...
