I did not test this; I'll give it a try.

yes, the relays click, and the pump whirls; confirmed last night. I like @gstaallons noid light idea. I may check into that as it would be nice to confirm it's working. I believe the injectors aren't cleaned properly. The thing is, even if they aren't spraying, they are at least squirting, it should still fire, and it's not. @LuckyPhil, they are installed correct, securely locked in. As for being properly grounded, I do have an understanding off this importance. I have not checked this, but I believe it is all stock so it should be correct. Laughable I know, but I'll still mention this, the owner said it ran when he parked it.

not sure about the click (ill have to test this), but the pump whirs. If I disconnect the fuel line at the injector, the pump PUMPS!

I continue to be able to run the bike by spraying starter fluid. Otherwise, it does not ignite/run. These injectors must not be spraying. It's either they are not being signaled to do so or they are being signaled, but aren't atomizing correctly, thus not lighting. Prior to removing them for cleaning or replacement, is there a test to be sure the injectors are getting signaled? Can I hook up a meter to the injector pigtail or something?

@gstallonsPlease, if you would, post the link to those injectors you recommend.

…looking at images from the day I received the bike, I see now I've swapped sides with the petcock and regulator. However, I don't believe this matters providing I've plumbed it correct. I'll be checking all of this hopefully this coming weekend. Why did this happen, 100% because of the service manual, their illustration displays it as such. As for your specific question docc about the two hoses, I'll have to give it a look when i get home from work today and report back.

Scooters are just silly fun, love 'em! For my wife's 50th, I bought her a 2018 Honda Metropolitan (4t/50cc). It only does 40mph. It was so much fun, it wasn't long before I bought one. I ended up getting a 2003 Yamaha Vino (2t/50cc). We ride all over! Congrats, and enjoy.

Sheesh, not sure how I became so mixed-up about this. I've now requested a cancel from the seller. Thanks Phil.

What I have found is nearly all ebay and amazon items, were purchased and resold from AliExpress. I've stop paying middleman prices and have bene ordering direct the last few years. The price difference is great. yes, I will get my OEM injectors to work.

a syringe can absolutely produce as much pressure as a spray can. 1 mL (363 ± 197 psi), 3 mL (177 ± 96 psi), 5 mL (73 ± 40 psi), 10 mL (53 ± 29 psi), 20 mL (32 ± 18 psi), and 60 mL (19 ± 12 psi).

"It is a free country and a person can do anything they want ." thanks, maybe I'll have them cleaned or altogether replaced, as I've sourced affordable replacements. First, I'll try to determine if they are functioning correct or not now.

yeah, i need a wrench to turn it. I couldn't pull it apart to repair either.

https://www.ebay.com/itm/143301245158 I haven't any connection to these, only just found replacements at a good price and wanted to share. These are sourced from AliXpress as further research revealed.

Look what I found, they just got my $25! https://www.ebay.com/itm/173280260339

so many aftermarket choices, will none of these options work for us? https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=12mm+petcock&_sacat=0&LH_TitleDesc=0&_odkw=moto+guzzi+petcock&_osacat=0

Great read, I didn't locate this when I searched a few months back. I removed my tap and after the circlip was taken off, that's where it ended. I could not remove the actual knob. I wasn't sure how and didn't want to break anything. I'm still not sure if it slips off or unscrews. I figured it was only an o ring replacement that was needed. As others mentioned, we don't really need to turn off the tap (w/FI), wish I could easily find replacement plumbing. As it turns out, mine isn't leaking so I'll just leave it on and monitor.

I removed each injector, soaked it in cleaner for a bit, then powered each from the battery while using a syringe to force cleaner through it.

yes, this is what I found, by far the most examples. However there seems to be stream style as well. Not sure what the V11 is supposed to be, but they are single hole, not multi-hole. After cleaning mine, both are single hole, with a sharp stream.

it is on the right. I must have mixed this up when reconstructing everything. Just the same, I don't think it matters, and I believe the plumbing is correct. I'll check again. thank you! looking at the schematic, it does seem to be on the right.

I'll double check the plumbing as suggested, I thought I had them correct. The size of the hoses, sort of dictate where they go as their sizes vary greatly. The petcock hose, from the pump is huge!

Thank you for these replies. Yes, this is mounted on the left side. Are you saying it belongs on the right? I figured counterclockwise opened this, and yes I needed a wrench to fully open it, lol.

After refurbishing my decade old idle bike, it won't start. If I spray starting fluid, it does. This means, it's a fuel problem. It may stem from the fact I don't know the proper operation of my petcock. The service manual, one of the worse I've ever used, doesn't even list my style, let alone how it operates. Mine does not have a solenoid style, see image. Anyone…?

I cleaned my injectors, afterward they produced a strong single stream. I thought all injectors were meant to produce a spray (mist), but these injectors have only a single hole, not multiples like most others. Quick research made me believe this is correct. Can anyone confirm?
