    Injector grease

    Can't seem to find the answer-Is the red grease type material aroung the injector o rings a specialist grease, or can I use my blue Yamaha grease?

    I was recently wondering the same thing and couldn't find the answer. When I recently pulled my injectors to have them flow tested and cleaned the red grease was gobbed on there pretty heavy all the way around above the O ring. What is the purpose of that? Why not just use a thin coat to allow it to slide in easy and call it a day. When I installed mine, I used Bel-Ray waterproof grease and just a thin coat.

    Gus that is fine. The grease is initially there to help with installing the injectors and fuel rail...
    some have used 2 stroke oil, water proof grease, Silicone grease, dielectric grease, spray oil, and whatever lube to properly seat the injectors and rail...
    What exactly is the orange/red grease the factory uses, IDK...

    I just would not recommend vasoline, they will eventually dry out the o rings... but in our case that could be a long time...

    I even read where people used KY!

    I Have an old tube of the red grease. Mine is made by Lucas/Girling (part# PFG102). It says on the tube that it is specialist grease for rubber fittings in direct contact with brake fluid, so I don't know why it's used for injectors. I use it for assembling the pistons and seals in brake calipers (its' original use). I would have thought a decent silicone grease would be a good alternative for your injectors. Regards, Dave.
