BansheeHoleshot Posted November 16, 2009 Report Share Posted November 16, 2009 Just wonder what the max size you can bore the stock cylinders? Quote Link to comment Share on other sites More sharing options...
SAVAGE420 Posted November 16, 2009 Report Share Posted November 16, 2009 .100, but i would only recommend going to .80 max! IMO Quote Link to comment Share on other sites More sharing options...
87sheerips Posted November 16, 2009 Report Share Posted November 16, 2009 I ran an un-ported set of stock jugs at .100 over for two seasons without issues. I agree with Chris though, Unless you are really attached to the cylinders I wouldn't run at .100 over. I bought my shee that way and it ran hard as hell for a stock set of jugs!

White97Banshee Posted November 16, 2009 Report Share Posted November 16, 2009 Correct. .080" over is a 66mm bore. Quote Link to comment Share on other sites More sharing options...
BansheeHoleshot Posted November 16, 2009 Author Report Share Posted November 16, 2009 I'm at 65.25 (.050) right now and I have grooves in my cylinders. If I can't get ride of the grooves with one size I'm going to be a 66.00 (.080) cause wiseco doesn't make 65.75 (.070) For the next time what's going to be the best thing to do? Thanks for the help Quote Link to comment Share on other sites More sharing options...
bansheesandrider Posted November 16, 2009 Report Share Posted November 16, 2009 (edited) Take them to a shop and have them bore them till they clean up, if it cleans up at 65.5, great. If it doesn't, the you will be at 66. Get the right pistons for whatever the bore ends up at and put it together. Run it till it gets weak again and then tear it down and figure out what you want- you can have the stock sleeves cut out and new sleeves put in, or you can get different cylinders, either stock, cub, powervalve or what ever you want. I am not positive about this, but I believe if you resleeve the stock cylinders, you can then go over .100 safely, because the new sleeve is thicker than the original and will disapate heat much better. Like I said, I am not sure about this, so if anybody knows otherwise please respond. Edited November 16, 2009 by bansheesandrider Quote Link to comment Share on other sites More sharing options...
