Hi All, A year ago I joined the ranks of K-bike owners and have been lurking in the shadows here ever since. Very thankful that this site and community exist as anytime I'm stumped or at a problem I have always found the solution through the post in the forum. I am posting to show what I have done so far and to get some help with engine troubles I am having. I have many things I still want to do to the bike just trying to get it to a point where I can ride it around and work out the kinks.
So here we go!
1987 K-100 RT Two owner bike 26,XXX on the odometer, original owner dropped the bike in his garage and broke a lot of the fairings so he decided to sell after about 25,XXX miles. The second owner patched the bike and put about 1000 miles on before tear down. When I bought the bike it had been scattered into a thousand pieces through a basement, garage, and barn.
The PO has restored many bikes and had a fairly large collection so I took his word that the bike ran well before tear down.
Frame Paint:
Wheels, Forks, Gear Box, Swing Arm, & Final Drive Blacked Out +New handle bars:
Engine remounted, Lubed all splines before reassemble, clutch measured 5.1 mm, Cut rear frame :nono for Unit Garage plate holder, mounted Unit Garage Headlight sub-frame, and fixed new seat.
New progressive suspension 412 shock:
New Acewell gauge & New OEM ignition switch (came with bike):
Covers all blasted and ready for paint - new gaskets with all & new bolt grommets:
I'm by no means an elechicken! This was the most tedious part of the bike.
And finally everything buttoned back up and ready to start riding! (or so I thought)
Problems Once fully Reassembled:
1.Fuel Rail hoses routed the wrong way= Had the supply side routed to the regulator then to the rail instead of supply to rail then rail to pressure regulator.
http://www.motobrick.com/index.php/topic,6689.msg45470.html#msg454702. Stuck Injector = replaced with 4 port injectors by suggestion from a K-bike builder.

4. Turn signals had a loud buzz and wouldn't flash = LED upgrade had to cut circuit board in flasher control unit.
http://www.motobrick.com/index.php/topic,659.0.html5. No pressure building in rear brake = rebuilt rear master cylinder and works perfectly.
6. Clutch is "frozen" or wont disengage = not fixed yet, going to try some of the methods on here that have been mentioned to break it free before I disassemble again.
7. Won't idle then engine dies and wont start when warm. = I feel that this is a valve issue from the way it sounds, but haven't yet dove into the problem. Here is it running rough.
As you may see in the pictures I am building the bike in a storage unit while I rent an apartment! (Wife said no more mechanic projects on the kitchen counters!) So I only have limited time that I can work on the bike. That's why I'm here talking about it and researching while I can't physically be turning a wrench!
Any suggestions on number 6 & 7 would be greatly appreciated or feel free to ask any questions regarding the modifications.
Thanks
Landon
