Hello all... first post here,
I recently purchased an 89 kx 500, but have some reservations, and have considered selling it. I have read, and read, and read on here, and now I have decided to ask a few questions.
Heres the deal,
my frame vin# reads out to be a 1989, but my motor cases read out to be mid year 1988. But I am somewhat still confused on the rest of the motor... the kips system has only 2 side valves, no top valve. And the "KIPS" embelem is glued on, thus leading me to believe that the cylinder is from an even earlier model?
My drive sproket is held on with a nut and my kickstarter is held on with a flange bolt. not an allen head.
The bike has a procurcuit pipe on it stamped "89" will this pipe work to its peak performance with this cylinder?
Am I way off base here? or do i have a bike that has been -miss matched, pieced together?
The motor has a fresh piston in it, and has a ton of compression, but does backfire occasionaly when im trying to start it. The key and flywheel are good, and the stator is on the middle mark.
the bike seems to have good power, but I just feel like somthing is lacking.
I have checked the kips valve operation, and it seems to be up to spec from what I have read on here.
Any help is GREATLY apprecieated. I plan on fixing this bike up nice, but I dont want to start with somthing that isnt what its supposed to be.
Also forgot to mention that it has a 39 pwk carb
