Thread: L.A. Sleeve

  1. #1

    Default L.A. Sleeve

    Has anyone used L.A. Sleeve before as am I thinking about sending them a set of cylinders, they seem to know what they are talking about on the phone but I know how that is sometimes?

    Thanks Steve

    I've used their sleeves. I've never heard of another brand.

    Years ago, okay decades ago, a friend had his 74" Knuck cylinders sleeved by LA Sleeve. While on a long ride he noticed the engine suddenly lost power and was running extremely rough. Between two of the fins, in the center of the cylinder, it had cracked completely around the cylinder. The two halves of the cylinder, held in place by the sleeve, were now separating.

    Which is always a possibility no matter who sleeved it.

    Once upon a time, Chris,

    I was working for a local speed shop, and a fellow brought in some shovel cylinders for sleeves.
    As I bored the castings for them, I noticed that they had been so severely over-torqued that they had lateral cracks at the headbolt flanges.

    I told the boss they wouldn't fly, but he said sleeve them anyway.
    And the customer didn't seem to care.

    A couple of months later another fellow came in to declare he had blown his front head into the frame like a cannon, immediately after he bought the bike from the first fellow.

    Boss said, "Too bad. You're not my customer."

    I've used LA Sleeve several times over the past 15 years, but all on triumphs and guzzis. Never an issue and one of the bikes I continue to ride regularly -- and am pushing 14K miles since the cylinders were sleeved with zero problems.

    Depending on why you need a sleeve, you may want to consider nikasil plating. It's about 20% less than a sleeve and holds up extremely well on iron cylinders and exceptionally well on aluminum cylinders. Don't believe the stories of nikasil separating from the walls -- it is stupidly rare on air cooled motors for it to happen.

    I have only used millenium cylinder for nikasil. Others offer the service, but I've no experience with them.
