Are the liners definitely pressed in? They can be cast in, in which case they are not possible to remove/replace.

its a alloy block with steal liners.
im sure you can buy new liners sleeves from america for this 2 stroke engine .

^^^ yes but how do they fit the new liners? If as ^^^^ says, they are cast in, then the new liners could be fitted by maching out the old liners?

dunno - maybe ask on a motrocycle forum?


oh, and remember how thre fitting goess - heat block drop in cold liner - to do the reverse you would heat block but without heating the liner - can't see how you can do that .... but the expansion of aluminum is bigger than steel/cast iron so maybe you can - something else top consider.

The theory is heat it up, and they fall out.

When you fit the new ones I think you will need to skim the head, so unless you can do that yourself you might as well get an engine recon place to do both bits.

I was told this by the nice chaps at http://www.robwalkerengineering.com/ but I suspect they are not close enough to you to be any use to you.
