TOPIC:

I went ahead and ruined the screw driver slot on one of the primary main jets, you know, because it will be fun removing a boogered brass jet that doesn't want to come out... grrrr, I have managed to remove one of the plastic plugs (successfully). I haven't tried the others yet.

left hand drill bits are good for extraction

Those primary mains can be a bugger. I've striped the head on them before too and also had the threads strip out of the carb body. Be careful.

The Kiehin CV34 carbs have both a Primary Main Jet (the part I messed up), and a Secondary Main Jet. The DynoJet kit states t replace "the main jet" with the one supplied in the kit (stage 3), but does not specify primary or secondary. It does state to make sure you are replacing "the main jet". The part I messed up has a larger thread than any of the parts supplied in the DynoJet kit. After checking on Partzilla, the part I messed up is no longer available. Has anyone run into this issue with the DynoJet kit before? I am assuming due to the thread size it is the secondary main jet that gets replaced - but then I need to find a source for the jet I messed up. Partzilla p/n 92063A.

#39 Primary Main Jet
#65 Secondary Main Jet

Also, how does the bleed pipe (#38) come out? Or does it need to?

DynoJet technical support suggested replacing the "secondary main jet" since it was the only one of the two that had the correct thread size (that was what I was assuming to be the case). Which leads me back to a source for replacing the "primary main jet" #39, in the diagram. Sometimes it's not easy to avoid damaging old parts that are frozen in place, soft material like brass, plastic brittled by years in fuel, etc.

I searched by year/model/carburetor parts, and they didn't show up. Thanks for the tip, Nessism! I find some things hard to search for on their website. Inventory is not cross linked very well.

I've restored at least half dozen sets of those Keihin's, during which time I learned a thing or two.

And speaking of that...be sure to inspect your float bowl overflow tubes carefully. They love to crack. It's not too hard to replace them so don't panic if they are. Also, be sure to remove the pilot screws; drill a hole in the cap and then thread in a screw which you can use as a lever to pull the cap out with Then make a small hook tool from a piece of wire and remove the spring, washer, and old o-ring before dipping the bodies to clean them.

I already removed all the plugs. They came out really easily. Should I remove the bleed pipes? They are underneath the primary main jets - I just can't see any screw driver slot. The one I messed up and had to drill out, I ended up kissing the top of the bleed pipe with the drill bit.

Yes, remove the bleed pipes. Push them out from the carb throat side. Be sure to remove the pilot jets too.

The frame, kick stand, motor mounts, battery tray, and a bunch of other brackets are off to the powder coater today! Might as well get those going while I tinker with the carb rebuilds. 8-D
