    pictures of VT1100 Injectors

    I just got around to installed a set of VT1100 injectors. I had a hard time with the stock clip to connect them to the fuel rail. I put on the VT11 8500 36 map. Fired it up runs like shit. So either the tune is off I hope..or these arent VT1100 injectors. Anyone have pictures of them or numbers on the injectors I can go by? Thanks.

    Did you buy them used?

    They are Bosch injectors but the numbers on them are scratched off. Out of respect for Vtech, I'm not going to post the specific model numbers but PM the numbers on yours and I will tell you if they are the correct ones (it starts with 0280...).

    Do you have a regulator?

    Got it...yep, those are the correct ones.

    What RPM does it idle on cold start?
    How many seconds does it take for the RPM's to stabilize when cold?
    You said it runs like shit...trailer or water?

    On the trailer. Flashed the tune. It runs lopey like it has a cam on it. Then when I rev it it sounds like its missing and stays lopey. It was cold and not warmed up. I wonder if one of the injectors is not working. Not sure never did injectors before on a ski and not sure what an engine sounds like when one is not working. Idle I am not sure didn't look at the rpms.

    It would be nice to get past the cold map and see how it runs on the warm map. Still, it shouldn't run this rough. Did it smell really rich (I'm betting it did).

    Not blaming injectors but with used injectors, you never know...

    You may have same problem I had. Long story short I found that the leads in the pigtail adapter weren't long enough. Jerry and VTech took care of it right away and have been good ever since.
    You can see in the pic the new connector on the left and wrong one on right.

    Where did you buy the injectors from?

    That is interesting. My connector is gray but looks identical to the blue left one.

    Since I am out of mechanical warranty, I may end up cutting wires and wiring the EV1 connector without an adapter.

    Hmm mine is grey. And the connectors are short like the grey one.

    My three most likely guesses. Bad connectors, clogged injector or a tune that is not set up for the VT11 injectors.

    Possible... what is your fuel pressure set at?
