    I have tested a few different carbs and I do like the performance of the Speed Carb the best

    Only Problem though is that banjo valve is the worst possible design ever.

    Have spent months finding an easy fix and waiting on wrong parts :$

    But the solution is here...

    First thing you need is a 90Deg. M8x1.0 Grease Nipple

    Pull the Grease nipple apart and you will be left with a M6 Female thread. At least mine was and i would think they are all the same.

    The grease nipple threads into the carb very tight :), even after being stripped


    Next you just need the M6 hose barb...

    The female threads on the grease nipple are kinda sloppy, so your gunna need some weld bond or something to make a good strong seal.


    But after that you are good to go.


    You might also want some hose clips... I find 9MM is good. 10mm is to big

    What about ditching the grease zert, and simply using a M8 nipple.

    you would loose the 90 degree bend, but probably not necessary anyway!

    Here is the finished product. No leaks at all now :) Perfect!

    Used J.B. Quick on the threads

    Used paper gasket as a spacer to get the angle right.
