About $400-$450 for parts and machine work on your 250 cylinder from Kientech to punch the DR250 out to 350cc.

Or buy the Thumper Racing kit for $400 and do the machine work yourself or have it done local.

Should be interesting to see the end result as the DR250 spins 1K more RPM than the DR350. 👍

Good read on the big bore here
