Madison Motorsport Posted February 8, 2009 Share Posted February 8, 2009 You could bore it out to a 650. Cheaper than a new engine. Link to comment Share on other sites More sharing options...

Moderator mervin Posted February 8, 2009 Moderator Share Posted February 8, 2009 well that looks to me like a broken liner (correct me if i am wrong) so boring it out would not be an option, fitting a new liner maybe would, is the piston damaged?? on the other hand get a block ?? merv Link to comment Share on other sites More sharing options...

Moderator Airhead Posted February 8, 2009 Moderator Share Posted February 8, 2009 Not up to speed on these ultra modern engines, but dont they have plated or coated bores? if so it could be a bit of plating that has gone awry, i suggest you find out if this is so and then take it from there. see this for example Here Link to comment Share on other sites More sharing options...
