Re: Another guy rehabilitating a K100

Finally got my 86 K100 to fire up without starter fluid or colorful language! To date I've replaced the fuel pump and filter with fuel line in the tank. I've replace the fuel line to the injector rail (after cleaning the rail) and the injectors. Replaced the oil and filter, rear brake rotor and pads. Still need a fresh battery, PCV hose and fuel line to the regulator. I can get it to idle but barely! Any throttle kills it. The idle is very low. I'm not sure if the fuel pressure is too low or if there is an air leak to the throttle bodies or ?????? Anyone offering suggestions would be most welcome!!


THANK YOU!!!!

There's no PCV on a K so I assume you mean the crank case breather hose. Wait until you have that installed or wrap the old one in electrical tape to keep it from leaking until the new one shows up.

That's an idea I can run with!! Thank you!

A few days after struggling to push my free bike home a tub of parts was delivered to my front door. It included lots of missing pieces but not nearly all of them. So here is the start of the story to recover this machine. Why was it so hard to push? Rear rotor and pads are a complete mess. They've been replaced. I also also decided to take a look at the drive shaft. It's in good shape and re-lubed!





New to the photo inserting so please feel free to correct my attempts!! Thank you!!

The drive shaft splines are "softer" and wear more than the FD input splines.

Middle of October and I'm able to ride without worrying about it stopping. I've replaced rubber bits like the breather tube and plugs on the throttle valves. At this point I have replaced the fuel pump, filter, lines, and injectors. It was all cleaned out as well. New plugs were installed so I didn't worry about their condition. This bike sat for 5 years with fuel in the tank. It was a mess. Currently it will idle well. Under acceleration it's a bit uneven. I had an issue with the AFM sticking in a wide open position. It left me stranded on the side of the road for a while until I discovered the stuck vane in the AFM.  I've done some work on it so it no longer sticks but suspect it's still not reacting as it should. The YouTube videos have been interesting to watch concerning working on this. The documentation I've found here has also helped to understand it. Anyone else have any sharable experience working with this device?
