sxr cooling on a big bore

I just installed group k's 834 c.c sleeper big bore kit in my sxr. Its an absolute rocket. What are some ways to increase my cylinder cooling??? I need to retain a stock appearance or stealth installation for cheaterstock. Let me know what you have tweaked or modified for that added cooling. Thanks in advance.
 
right on sc8, first called harry, then changed fittings. hope this helps cool the cylinder. dont want to run dual lines because it might be hard to hide from tech.
