I've got a polaris(white bros) slip on for an 800 and was wondering if I could put it on a 500 w/o leaning out the bike? Would it hurt the engine at all or even the computer? The 500 is an 07 EFI just save any questions and I do have a k&n air filter.

 

No one knows? Somebody's got to know, all you gearheads and greasmonkeys on here!LOL!!

 

something i didn't mention(but you alredy know) is too keep checking the plug to read how it's burning and if real lean then it's remapping time. imo.
