GL1000 Carb Rebuild

Postby pshaginaw » Tue Mar 13, 2012 4:16 pm



I'm rebuilding the carbs for a '78 Gl1000. Carb bodies are 771A. The needle jets that were in the vacuum slides on disassembly were 54.45mm long with #452304 on them. The rebuild kit from Napco Corp. has needles that are 56.2mm with no code. Which are the needles I should use? Short will make the mixture rich, long will make it lean. I have no idea how the bike ran when it was last registered in 2002. There is evidence that the carbs may have been apart before, but all other jets match stock specs. I have a Randakk kit for all the other parts, so I'm sure they will be correct. Please help!

I would email Randakk and see if the ones that were in there are right. Unless there is damage, they don't need to be replaced.( if correct)

I agree with scotter, unless they are damaged then reuse. Jets do not wear out on this bikes until mega mile status.

Thanks for the good advice. Randakks archives show that the needles with the code number were indeed the correct ones. A little brake cleaner and a soft cloth made them as shiny as the ones supplied in the rebuild kit.

Good thing you checked that out, now if you have any issues you will know it is not those jets that are the new issue. Do follow all Randakk's rebuilt tips, and watch the video if you can as there is really no such thing as too meticulous when putting GL1000 carbs back together.
