Or wait for somebody that has a stock bore that needs a bore ! , then you can get it ported and head mod and be the same as an un ported La , From what i have heard !
 
.010" or .25mm is a single oversize. The stock blaster engine is 66.00mm and has 9 more lives in .010" (ten thousandths of an inch) or .25mm steps all the way up to 68.25mm. Wiseco is the only company I'm aware of that sells a 68.25mm or .090" oversize piston.

You have a few choices when it comes time that the last bore size is gone. You can either sleeve the cylinder back to 66mm, sleeve the cylinder to big bore, buy another cylinder in the hopes that it has more life, or buy a replacement big bore cylinder.

i would probally re sleeve it i guess im on my second to last life if its on 68mm so .80" ?
 
yes. If your engine is currently at 68mm, it's 2mm or .080" oversize. There is the current life and one more overbore available.

Generally, unless this is a race engine we're talking about, bores should last a LONG time.
 
If you're only an occasional rider, the BIGGEST affect on engine life is regular maintenance. Keep your carburetor clean, leakdown test, plug chop, and jet accordingly. Twostroker99 is meticulous about his maintenance and he's on stock 66mm bore from 1999!
