kyleag89 Posted December 1, 2010 Share Posted December 1, 2010 I just picked up a 97 Polaris Scrambler 400 for $275 that needs a top end. Does anyone know a good place to have the cylinder bored/honed? Quote Link to comment Share on other sites More sharing options...
Dirteatr717 Posted December 1, 2010 Share Posted December 1, 2010 I have a few of my toys bored over and fully rebuilt by a company about 20 minutes from me called Diggins racing.... Very nice guys, quick and not cheap but not going to tear a hole in your wallet... Check em out http://www.digginracing.com/ :thumbsup: Quote Link to comment Share on other sites More sharing options...
87Warrior Posted December 1, 2010 Share Posted December 1, 2010 I just had the local machine shop do it for me back in the day for my Yamaha Warrior and Blaster top ends. Take your piston in and let them have at it. If it is a 2 stroke, make sure they chamfer the ports leaving no burrs or edges. Quote Link to comment Share on other sites More sharing options...
kyleag89 Posted December 1, 2010 Author Share Posted December 1, 2010 I'm not going to buy a piston until I have it bored because I don't know what size it needs to be. Quote Link to comment Share on other sites More sharing options...
87Warrior Posted December 1, 2010 Share Posted December 1, 2010 The exact bore size, if done properly, is matched to the piston ;) Quote Link to comment Share on other sites More sharing options...
kyleag89 Posted December 1, 2010 Author Share Posted December 1, 2010 I understand, but the cylinder is really scored and they may have to bore it larger than the next size up or I might need a new sleeve. Quote Link to comment Share on other sites More sharing options...
kyleag89 Posted December 3, 2010 Author Share Posted December 3, 2010 Sent it to a place in FL to be bored. http://www.summitoffroad.net/ $175 includes complete bore, new piston and gasket kit. Quote Link to comment Share on other sites More sharing options...
