New Cylinder Sleeve Installation Questions

If I were to purchase new cylinder sleeves for my 1000cc block and install them myself, would the top surface of the cylinder block then need to be machined?

Also, I know the block needs to be heated in order to remove the sleeve. The last time I did that I used the kitchen oven, which made the kitchen stink like burned motor oil...

That was years ago when I was single and I could do such things. If I tried that now my wife would murder me! Is there any other way to heat the block up?

???? Cheap old worn out barbecue grill ????

just press them out cold.you will be fine.you will have to measure the lip on the old sleeve's and check the new one against that.i do a bunch of 2 stroke sleeves and they always have to be decked.if you are buying a "drop in"sleeve they may be the same already.you will need to heat it up to re-install the sleeves tho.get a good thermometer for your barbeque and take it to 450 for 45 mins and freeze the sleeves the same amount and drop em in and let em cool with a little press on them.my.02 fwiw

Thanks for the input! A BBQ should work great!

Don't need to freeze the sleeves. After the new ones are installed and the block has cooled, you need to press the sleeves on the top. They will drop a few thousanths. Thes it needs to be surfaced.

To heat them, we use a two burner hot plate from Rite Aid, covered with a metal tote pan. Plug it in for one hour and you are ready.


KZ1000 sleeves are loose in the block from the factory which sometimed presents a problem when honing them.

Several years ago, a customer pulls up in fron to the shop on a nice sunny day, in his pickup. jumps out, reaches in the bed and picked up his block. As he turned to come into the shop, all four liners came out and were rolling around in the street.:lol:
