    i just made THE mistake

    I was being a good boy following Bikecliff's VM carb dip process,
    making sure everything was clean and with new o-rings.
    On my 3rd carb I was rebuilding, I went to screw in the pilot
    fuel screw and I felt it start to get a little tighter as I turned it in.
    I was like, alright, just a little bit..... hmm. it didn't feel good.
    I unscrewed it and sure enough the tip of the needle was broken
    off. I saw the needle sticking out of the carb body on the inside,
    so I tapped it out thank God, but now I need a new needle.
    So my question is, where can I get a GOOD factory pilot fuel needle?
    (VM carbs, 78' GS750)

    Unless the carbs have been changed, the 78 has VM and not CV carbs.

        You may want to post a request in the parts wanted section. Perhaps someone has an extra one lying around. If you find that the screw is hard to find, you many want to think about picking up a set of carbs to use for parts. My bike uses the BS32 carbs and I own 2 extra racks of carbs in case I need parts.

                You have extras?!?! those are so hard to find without the K&L rebuild kit...

                When I did something similar, I resharpened the screw, probably ot perfect but I cant tell if it worked until I get the bike running!

                  I used the K&L kits but swapped the o-rings with better rubber from bwringer.

                  I still have my old jets though, because several posters suggested that the K&L brass was crappy. My original jets were pretty grimy, but they were not broken. I am happy to send the OP one of the old jets (probably just need a better cleaning, definitely need a new o-ring) or one of the leftover K&L jets (can't recall if I swapped all four).

                  I also picked up a spare rack of carbs off eBay for $9.99 (+$10 S&H). They were being sold for parts, so I am not sure of their condition. Pretty sure I can salvage $20 worth of parts from them though.

                  In short, I am a giver.
