No start woes! I've had this bike a good long time, this is the first no start for me.

FI primes just fine. Flow from fuel pump is confirmed. Cranks and turns over strong 3 of 5 attempts (I owe this to the standard voltage drop/solenoid clunk issue). Spark is confirmed. Trans in N. N safety switch function is confirmed. Choke lever has been tried at various positions. No love.

History: Until this month, the bike sat a bit and was emptied of old gas (appx 2 years, aplogies!). Previously I had bypassed the sidestand safety switch by connecting green to black (colors are off the top of my head) and I've checked that connection. (To be clear, it used to run this way). Batt is new and charged. All fuses have been checked multiple times. I have not confirmed power to the injectors, but will today.

All thoughts are welcome.
 
Will do John, thanks! May be a while but I'll report back.
 
It is clogged injectors. I have confimed fuel flow to the injector, and power to to injector at pre-igniton (power up sequence).
Bummer is, I damaged an injector upon removal. I broke the plastic electric fitting at the base...thought I was being easy on it too! Are injectors pretty much a dealer only part? I'm showing GU32115710, but no major US sources are popping up.
 
There is also a Marelli number on it if you have no luck w/Guzzi. The price on them went way up a few years ago.

If you hadn't broken one they could be cleaned. Probably easiest to just order from a dealer. Also you could check with Todd as he might have a source. You can use the contact button in the store area to ask.
 
Dealer will have a new set for me in a few days. Appx $55 per. I was prepared for worse.
Thank you John and Steve!
