Every time you change ANYTHING that affects the restriction of either the intake or exhaust, you need to re-jet to make sure you are getting the proper stochiometric mixture.  I use a "Color Tune" kit. -Jeff Khoury [b]From: [/b]"notanymoore" [b]To: [/b]"DSN KLR650" DSN_KLR650@yahoogroups.com> [b]Sent: [/b]Monday, January 17, 2011 8:37:28 PM [b]Subject: [/b][DSN_KLR650] What's the best approach for add'l HP on a KLR650 without rejetting?   What's the best approach for add'l HP on a KLR650 without rejetting?
