SteveCZ28 Posted July 12, 2011 Report Share Posted July 12, 2011 ok ive seen a few sets of big bore cylinders for sale. and i am curious how to make stock cylinders into a big bore, being as i believe the stock cylinders are maxed out at 66.5 mm....but ive seel some that are 69mm so how exactly do you make them into big bores? is it using a different sleeve?

STINKYDELUXE Posted July 13, 2011 Report Share Posted July 13, 2011 by installing sleeves (http://www.bansheedepot.com/products.asp?cat=45) but I think in the long run you would be better off buying a used cub Quote Link to comment Share on other sites More sharing options...
SteveCZ28 Posted July 13, 2011 Author Report Share Posted July 13, 2011 But about how much does it cost to put sleeves in? Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted July 13, 2011 Report Share Posted July 13, 2011 by the time you pay to have um installed, have the ports matched then have the cylinders ported you would be ahead to just buy an aftermarket cylinder.... plus the stock cylinders dont really have enough transfer area to support a big bore sleeve.....

Paulie B Posted July 15, 2011 Report Share Posted July 15, 2011 Sleeves are the way to go for anything other then drag racing. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted September 19, 2011 Report Share Posted September 19, 2011 (edited) "Sleeves are the way to go for anything other then drag racing." NO, NO THEY ARE NOT! My motor has been one long culmination of issues and after sorting it all out, the motor still gets out ran by standard cylinders with solid port work. And Im not talking about drag bikes either. Old tech, Old theory, old school thought. However, I ran a set of weld up cylinders that arlen formerly of LRD set up, and they absolutely killed almost anything short of a properly set up cub. but when you factor in the cost of sleeving($4-500) decking($50) tig & rework transfers/Porting ($750-850) A few years ago that would of been the top dog, but now with the availability of aftermarket cylinders you would be a fool to pay some one to build you proper big bore cylinders.

Larry's Shee Posted September 20, 2011 Report Share Posted September 20, 2011 It's the cost of labor that kills it. That's why its cheaper to but a new crank rather than rebuild. Quote Link to comment Share on other sites More sharing options...
