A big thanks to the posters on this forum. I have a new-to-me 2003 750, my first Kawasaki. I've had Harleys, Hondas and a '46 Indian Scout. Started riding 60 years ago with a Cushman Paratrooper.
First thing was to download the service manual and read it. Second was to browse the forum. Lots of tips and information here.
So far I've serviced the drive train (splines were great), changed all fluids, added a sidecar, swapped ACCTs to TOC MCCTs, thrown on a windshield, fixed the choke, replaced one CC adjuster stud (cured oil leak) and tightened bolts. I will be relocating the Rectifier and finding the weak connection in the tach.
Found out the bike sat at the dealer for over a year (nobody wanted a "little" 750) so am running Seafoam in oil and gas. Oil/filter change in another 150 miles.
Thanks again everyone.
