Hi Guys,
I have a 91 KDX 200 that isn’t far off needing a rebuild. The bore is in a sad state, with some cracking between the exhaust ports (not very deep). The nikasil lining is worn through down the bottom. So I figure that If I am going to be spending a heap of money getting the 200 re lined, then why not go out to 225! I have heard that this mod will give a significant increase in power and would be interested in hearing from people who have done this. I also would like to know what the new piston size is, and what its out of…is it just a common aftermarket size? How much does this cost you guys in the states? ( I am in Oz). If its going to work out significantly cheaper I would be keen to post the bore over there and get it shipped back. Any thoughts or advice would be much appreciated.
Brendan
