is the cylinder liner supposed to be slightly raised from the deck of the cylinder ? It's not alot, maybe .006-.009" but the steel(cast iron?) liner definitely sits higher than the aluminum cylinder. Just wondered if this is normal.

For what it's worth,i just checked on a set of 2000 M2 cylinders and the iron liners look to be flush(they even have surface machining marks that match with the aluminum they are cast?or pressed? into)But,maybe 1996 cylinders are different.

Thanks Spiderman and Jrh
I think they are pressed in, maybe somebody could confirm that. If so then heating could realign them. Could be the reason for the head gasket heading south if the pressure sandwiching them is not uniform. I'll clean them up and then run a straight edge across it to see what the difference is, as long as it's under .006 I should be okay.

have them trued at a machine shop if you plan on using them. .006 is still too much sticking out. your head gasket will blow again in a matter of less than 1500 miles depending on the run and gun factor. do yourself a favor, been there-done that. sorry i'm so slow to have seen your post.

Quit messing around with them. If it has already shifted, it's gonna shift even more, if you re- use them. It's not worth it.

The HD /Buell cylinders were upgraded in I believe 1998 just because of liner slippage... I believe the new liners are grooved....

Thanks for the offer Bud, but considering the differences in the engines I don't know what kind of work I would be getting myself into.
Does anybody know if 16444-94Y comes with rings and circlips ?

I THOUGHT that the cylinder was cast around the liner instead of the liner being a press fit.

Ok here is the scoop on Buell an H-D aluminium barrels.
The liner is a smooth steel core that aluminium is cast around tand then finished machined.
That was till 2001 when Buell and H-D introduced Spinyloc Cylinders. Instead of the outside of the steel cylinder (the side that contacts the aluminium) being smooth it had sharp, unfinished surface so the aluminium would form to it better so the walls of the cylinder would not pull away from the aluminium.

Hair Splitting time...

When you say 2001 - do you mean Model Year 2001 or whatever date a jug was cast? When in 01? Do these jugs have distinct part #s? You sure they weren't called Spideylock?

They were introduced in 2001 as a upgrade. Yes they were called spiny not spidey LOL I should be so lucky.
I couldn't find a change in part number which is odd. Maybe I just didn;t look hard enough?
BUt when the 01's came out Reg Kittrel did a article on all the updates on the 2001 model years which included things like, hidden wiring harness the spiney lock cylinders, etc.

I remember the spiney lock thing. but that is more for heat dissipation than slippage isn't it ? I wouldn't say the cyliner moved in the barrel just that the finishing wasn't done correctly.

If your iron liner is higher than the cylinder, it IS slipping. The Spiny-Lok(TM) was for the slippage, which is fairly common in the early cylinders. Replace your cylinder(s), or it is gonna end up costing you more down the road.
