If you have the time let me suggest this. If you send your cylinder to Ritter Cycle racing and let Rick Ritter do the bore and send you the correct rebuild parts, Wiseco of course, you will not regret it. He is the Polaris 2 stroke expert. He will feather all the ports after the bore and it makes a huge difference on how long the rebuild lasts. He did my 02 Trailblazer 250 and did an awsome job. I would give him a call before I did anything. Rittercycle.com
