Just ordered a gauge 0-100psi.

OK UPDATE:

Fuel pressure from pump is 45psi.

Running condition:
  hard to start
  when starting; occasional popping sound from intake. Almost like intake valves are being slammed shut or spark timing is off.
  idles low when cold and "cold start" lever is off. Stalls.
  high pitch ring at ~4000rpm
  sounds like knocking when under load
  regardless of Termi slipons, the bike is really load (louder than usual).

That fuel pressure is OK.

Perhaps the TPS is fuxxored, or is way off.
Or the trim is at some crazy setting.
Both are easy (read cheap) to check at a shop, or if you've got the VDST or similar diagnostic equipment.

I really wish this wasnt my only ride. Every shop wants to put it in the que and "get to it" in 4 days. Nick you are awfully far away for me to get rides back and forth from. What would be the best way to test the ignition timing without a diagnostics computer?

Well, you could call and we could set up a time where you can ride it in and I can hook it up and see what the ECU is doing/saying.

You could try checking the ignition timing with an inductive pickup timing light, you know anyone with one of those?

lucky you're not near me, my next day is july 29.  do people make bookings in the usa and wait for that day to come then drop the bike off?  seems to be a lot of people dropping their bikes off, then waiting for the shop to work on it.  just seems to upset everyone.

if it is injected, then the timing is not adjustable and no one ever checks it anyway.
