L.A. Sleeve

[Coolbreeze]

The LA Sleeves in my '48 Chief have been working great for over 20 years now. I am so pleased that I had that company sleeve my '56 KHK this year.
The original Nikasil cylinders are doing fine in my 1984 Moto Guzzi V65Sp; so, that approach is also excellent -- if you have enough good metal left in your cylinders.

Just had LA Sleeves do a set of their sleeves installed in some oversize OEM knuck cylinders. My buddy had a set done 20+/- years ago and they were fine. Based upon that, we opted to do use them again. So far, so good.
They do seem VERY knowledgeable.

I Have had great luck with them and advanced sleeve's products. I have always done the machine work in my shop though
