YOU GUYS ROCK. Thanks much for the answers. I called Clifford and he said he goes to you guys or the Santucci book for ID issues such as this. Yeah,duh, I guess I should have just measured the bore but I figured there must be SOME Inliner who has run up on this issue before. Anyway, much thanks to Chris and CNC Guy for kind assistance. Now the fun part: ripping into my newfound 250 to see how bad or good it looks in there.
Thanks again!
