I put that pump on it becasue I had it on the shelf, more or less to test the theory about the fueling causing the stall issue. I figured the stock pump that was only putting putting out 35 psi (not even enough to open the FPR) was bad, so this is all I had. It works pefectly fine now, but yeah I am sure its bypassing alot more fuel than it needs to volume wise, but the pressures are fine. Once this thing is ridable, i can swap out the pump for another bosche replacement I found for aorund a hundred bucks. But for now, it looks like more money is going to get dumped into it for clutch work. No lay over/crash switch on the bike. I will test the switch and research what the switch is suposed to tell the ecu. I swear last night, and even yetti said it, why is that a 4 wire on the kick stand. But on the diagram is says its 3 wire into 2 at the plug (25 on the diagram). So maybe I am just loosing my mind (good chance). Diagram says blue/black and black is grounded. BBK goes to pin 16 on the ECU. Also looking at the diagram, it looks like the nutral switch (33 y/g wire) only lights up the dash light. i dont see it returning to the ecu at all. Unless its passing through the bulb and back somehow, which would be dumb, bulb goes out bike wont run!

Sooo… Has anyone here ever tried to slowly feather out a start in 2nd gear??? :banghead Clutch stack is within spec, everythings in there right. Tried it again, and same thing. then I feathered it out up to a good clip and almost had it engauge… and thought to myself “damn I am really moving here, what a tall 1st gear!” waiiiiitttt a minute. Kicked it up into 2nd, tried to launch it, same exact feeling and everything. somehow 1st foot position is not clicking over to 1s gear. its stuck in 2nd somehow. We are going to kick it in “1st” and 2nd gear, clutch in and roll it one tire rotation, clutch basket marked, and count the rotations. then do the math and it will tell us for sure what we think is happening. :skid ---

ALL THE FACEPALMS on a related note. Aparantly this is what i bet is out of adjustment. it works a little, so its not knocked off. I bet its just not hitting the pins like it should on the drum to hit 1st ![http://www.ducati.ms/forums/attachments/superbikes/53913d1251779208-duc-down-time-i-think-its-bad-img_8937.jpg](http://www.ducati.ms/forums/attachments/superbikes/53913d1251779208-duc-down-time-i-think-its-bad-img_8937.jpg) Its a common thing i guess for people to get locked out on these bikes. The drum controll fork needs to be adjusted alot they say. ---
