Title: Re-sleve
Post by: medicman on March 29, 2007, 04:33:54 PM
hey guys, I bought a 04 kx500 and wanted to have the top end done just as a prevenitive mesure. the guy i had do it said the nikisil had some gouges in it from sand. he suggested that i have it re-sleved insted of bored/ resealed. how is the reliability and perfomance with a re-sleved piston? thanks for your help!

The cylinder could just be re-plated. lukesracing.com 150.00 for mine last year. Without looking at you cylinder it hard to determind the damage.

Sleeves make the bike run hotter then with a Nikisel sleeve. I bet it would cost more too since your including the cost of the sleeve plus labor to have it installed.

Sleeves run hotter and seem to wear faster, but the advantage of sleeves is you can bore then a few times before replacing them, as plating has to be replated.. But plating lasts much longer IMO. If I were going to sleeve, I'd just have purchased a CR500.

 Go with the nika-cell, buddy. It is perfect fix for your problem. Hope you don't have to wait for a month to get it back like I did. They hone it out fill it in and machine it back out to stock spec's. I had some damage to my ports and still come out ahead by having them fix it. Fresh, stock-cylinder with a new piston, and a little time to clean her up, oh heck ya. Put on a nasty back tire with the money you save!!!!!!

Well i hope i dident make a mistake.... I had the bike resleved last week and it runs great! I should of waited a little longer and weighed my options, but i got impatient and just did what the guy at my local shop said. here is another question? once a cylinder is resleved can it be removed and re-plated?

when they sleaved the cylinder they likely machined the jug to a larger diam. to accept the thickness of the sleave. the only way to get the original size back would be to have a machine shop build it back up and machine back to proper spec. then of course comes the nickasil plating. although i am not even certain that it can be done. just some thoughts, MADDOGGY.
