How to re-sleeve a cylinder


jmeperu

This was done on a 400cc single but it works on twins and 4 cyl's as well. Clean your cylinder and get as much oil out as possible and freeze your new sleeve or sleeves.

Use an oven to heat to 450 deg F

push cylinder down and most of the time the sleeve or sleeves will pop up

use an oven mitt or welding glove to pull the sleeves out. if they dont pull out then gently tap them out with a large tipped punch.

remove new sleeve from freezer and drop it in.

you will still need to have a machinist face the top of the cyl and bore it to your piston, but you saved yourself a few bucks.

      Hey guys,  
      I have a 1969 (approximately) Honda Z50. It was given to me after my uncle died. He would ride it around the dirt lake road between our families houses with a beer in one hand and a cigarette hanging out of the side of his mouth laughing the entire way. If you've ever seen or owned a Z50, they are a little ridiculous. All I wanted when I was younger was to ride his mini bike but I never got the opportunity. After he died, it sat in his garage for a number of years until i eventually came to own it. 
      Unfortunately after sitting for so long, it is not starting at the moment. In addition he was not much of a mechanic so it needs some serious TLC. I thought it would be a great honor to restore it in his name and put it back on those lake roads. 
      I need help guys. I can figure my way out around a bike but I am a little curious where to start with this old hunk. I would be happy to get it running again but I am also looking at possibly engine swapping this little guy (80cc or 125cc) if possible. And I know what you're thinking, "waste of time.. or this idiot has too much time on your hands"......agreed but I think you can agree that would be pretty badass. And for the short amount of time this thing gets used it would be a fun little project for nights at the lake. 

      If you have any advice on where exactly to start or if the engine swap is possible please let me know. Not looking to hear from any of you automatic 'nay-sayers,' have a little imagination and appeal to your younger 12 year old self. 
      Thanks, 
      Chip

      Hi everyone, 
              So I recently purchased a 2001 YZ250 with no Engine. I am looking to make it in to a single track enduro bike. I am right now looking for some what of a complete engine and have come across one recently pulled motor out of a 2011 yz250. To my knowledge the only thing different about the motors from pretty much 99-Present is the swing arm pivot. I guess they changed sizes in 02. I was wondering if anyone knew if it is possible to interchange that 2011 engine into an 2001 frame?
      Thanks!

      With this trick billet aluminum filter system, you can re-route the crankcase vent hose to eliminate oil mist and crankcase contaminants from entering directly into your carburetor or throttle body
