No such thing as an aluminum sleeve....If you need your cylinder bored and replated, I'd suggest Millenium Technologies...Just send your cylinder with your new piston to them and it will come back ready to build. Leave all the guesswork to the pros !

Aluminum sleeves are common, but they need to be nickel/silicone plated or they would be destroyed in a few hours of run time. Since the little ttr comes with an iron sleeve its not necessary to get an aluminum one but you certainly can if thats what you prefer. You can get a custom made sleeve somewhere like LA Sleeve, or advancedsleeve.com, and the same shop that did your jet ski will have no problem doing the ttr.

The cylinders are aluminum with cast iron sleeves on a bike like the TTR. A lot of bikes come with an aluminum cylinder and the bore is coated with a super hard surface like Nickel Silicon Carbide Composite or a variety of similar processes which then makes the aluminum cylinder have a hard enough surface to be used in an engine. I did find a company that offers alum sleeves that are coated, which makes no sense to me...You can send your jug to Millenium Tech and they can bore and coat your cylinder for less than the sleeve + machining costs.
