Snopczynski Posted October 22, 2010 Report Share Posted October 22, 2010 do you need a special coolhead for them, or does the stock type coolheads work? Do you need cut stroker domes? Quote Link to comment Share on other sites More sharing options...
No Limit Powersports Posted October 22, 2010 Author Report Share Posted October 22, 2010 do you need a special coolhead for them, or does the stock type coolheads work? Do you need cut stroker domes? A stock style head will work. Standard cub domes will work. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted October 22, 2010 Report Share Posted October 22, 2010 So they make machined cub domes for coolheads to run in em? Quote Link to comment Share on other sites More sharing options...
bode1 Posted October 22, 2010 Report Share Posted October 22, 2010 (edited) Can you take anything off the package if you don't need the crank? Edited October 22, 2010 by bode1 Quote Link to comment Share on other sites More sharing options...
No Limit Powersports Posted October 22, 2010 Author Report Share Posted October 22, 2010 So they make machined cub domes for coolheads to run in em? Yes the cub/serval dome will fit a stock style cool head. How much can you take off the package if you don't need the crank? Were really able to pass on the savings as a package deal. On top of the fact that there are a million combinations of packages that we could do and never suit everyone. PM me and ill set you up with exactly what you need.
