You've been mostly-dead all day.
DTT BOTM WINNER
Right, what I'm suggesting as a possibility is swapping the good sleeves into the better cylinder casing. I did this on my CB650 engine.
I would personally not install that. That little cracked chunk looks ready to break off and destroy your engine while it's getting ground to bits by the crank and transmission.CALfeRacer said:Bumping this thread instead of making a new one... taping everything up to go out for media blast and noticed this. It’s where the chain tensioner mounts. Should I just slather some JB weld in there or is this Toast?
I do have another set of cylinders, but the bores are gross and would need to be bored out for the bigger pistons (unlike this set of cylinders).
How hard was that? I assume throwing them in the oven to pop out sleeves and then freezing the good ones to put back in?irk miller said:Right, what I'm suggesting as a possibility is swapping the good sleeves into the better cylinder casing. I did this on my CB650 engine.
I’ve already blown up one engine going 70, and I’d like to avoid doing that againSONIC. said:Agreed. If that little chunk breaks off and lodges in the transmission at 70mph you'll really be wishing you had not put it back together that way lol
Yep, I've had them drop out during powdercoating so it doesn't take much to get them out when it gets hot!irk miller said:That was the first time I swapped sleeves. Every other time, I have sent them out to be bored. On the 360s, i take it as an excuse to do the GS piston 378 bore. It really is pretty quick and easy. I have kilns, so I put it in my kiln until the thermo couple read 350°F. The cylinder body was up on refractory bricks to where the 3 good cylinders were directly on top of the bricks and the bad cylinder was open underneath. A very light tap with a brass hammer and the bad sleeve slid right out. I had the good sleeve in the freezer just long enough to be ice cold to the touch, so not a crazy amount of time. Same deal. Heated the body up to 350° and dropped the cold sleeve right in. It took zero effort. Just slid in.
