Ha! Bought a running but clapped 93 couple years ago. Rode it twice and tore it dkwn. One ride was the purchase test. Accumulated goodies for a year.
Finished it up this spring. New tire, new wossner purchased from powerseal with replate, mains with seals, squish and compression release by Larry Wiechman, gasket and seal kit, chain and sprockets, couple trans bearings, clean and grease all chassis bearings, fresh brake juice, throttle cable, and blahblah.
Fired it up. Rolled my track cautiously. Around the track again with a bit more gusto. Open it up to run the front yard trail. Found air near my driveway on the k5 that no other bike could ever find...then skidded into a stack of a dozen utility poles laying in my yard. Hard.
Out of work for 6 weeks. Fractured tibial plateau (lucky that was all.....3 cartwheels before MY first bounce according to several of my sons buddies). New handlebars. New grips. Little tweakin' on the subframe. Sat until this October when I posted it on cl (plenty other toys).
Finally, after 4 or 5 years of talking about it, took my son to badlands ohv area and I chose the k5. Stock but fresh everything. He took my kdx200 of the same vintage. We had a blast! The k5 is no longer listed!
https://youtu.be/d0nVPqWhb28Went from a 60 pilot to a 55. Blubbering like crazy. Video is with a 52, stock needle, clip all the way at the top. Still feels rich at small throttle and idle. Feel like i checked float level already, but winter is here and I do have a nice place to wrench on it during winter.....
Threadjack over.
Powerseal did find cracks in my transfers (I think, or maybe exhaust) but money cures almost anything.
With the proper tools, a manual, a bit of mechanical aptitude and this forum you could probably get it up to snuff with a minimum of outsourced work. Just sayin....
