I just did a big service on my brother's K1200RS ('03). Valves, 5 fluids, 3 filters. It was running fine before I got my hands on it.

I've done dozens with no problems. This time it ran fine then died after about a 1 mile test ride acting like out of gas. All tubes and wires were connected properly. I used an aftermarket "equal" fuel filter. I did checked the flow of both OEM and the China one, and could see no difference but didn't check pressure.

I changed back to OEM filer.... no diff. still won't start.
I checked voltage to the fuel pump. Brief 12v when key on, then off until hit the starter, then 12V. Normal I think. Plenty of gas flow when pump is running.

What have I missed? Help

The LT often suffers from a split "U" shaped hose that is hard to see unless you look at it under pressure. If you were just pumping gas through it would appear fine but as soon as you built up pressure it would spray out.

Mine did the same...fuel line popped off the pump in the tank.

Stupid stupid mistake....be kind

I found the problem and I feel like an idiot. Hopefully someone will learn from my mistakes.

I tested the fuel pressure where the hose enters the fuel rail. 60lbs during starter using the bike's connector, 60lbs with 12V. No answer there. Time to take a nap.

After short nap, I decided to check my valve job. It only need 1 bucket on the EXHAUST cam.

When I opened her and rechecked the torques I found the sprocket bolt on the INLET cam loose. I don't remember touching it, but I must have. Apparently it took about a mile for that un-torqued bolt to loosen enough to stop turning the inlet cam.

I don't think any damage was done. The groove in the cam is perfect and the key on the sprocket is just rounded on the tip. 95% is there.

The bike started right up, sounded good, and no smoke (after usual belch from being on the side stand several days).

John, Mike, thanks for your suggestions. I check both right away.

Sounds like you lucked out.

Lesson that I learned from this thread--never under estimate the value of a good nap. :histerica
