Wiesco makes a pistons up to 88 mm, LA sleeve has a 89mm piston. You can use the newer piston in your bike. Evidently sombody has already sleeved your cylinder, originally it was plated.

my piston is pn 575m08700 but can i boar me sleeve???

[don46]

OK so your piston is 87mm, I assume somebody installed a cast iron sleeve, if so you should be able to bore it. does it have a cast iron sleeve? or did it get bored and replated at 87mm. Actually is the cylinder damaged, if not why not replace the piston with the same 87mm, of course thats after checking to make sure it's within tolerance
