I've had 2 brand new K-5's before. Stock was impressive but the power range needed alot of attention, & to be cleaned up.
This Stewart built engine is amazing.....i simply cannot stop talking about the super wide power delivery. this thing is in power right off idle, but maintains decent tractibility for a 500 cc
I'm not really sure what is done aside from a carb, & exhaust, but whatever it is....is simply amazing. I know some internal stuff or whatever....don't really care...LOL !!!
Sorry for rambling on & on, but i'm super stoked to have this steed as a stable mate to my 05 CRF 450 R
I will be jumping this KX....she will fly.... pics to come.
