Topic: Another overkill tool build

I think some of the hospitals in southeast asia still use IV drippers that look like
that....not sure about the pressure pump though.

cbj: i bought mine from my local m.c. shop for $30. if they're selling them for that retail, they've gotta be out there on the web for cheaper...

I used this contraption this past weekend, and had a learning opportunity.  The metal line coming into the caliper has to be the highest point in the caliper when pressurizing, otherwise a little tiny bit of air can still get trapped in there.  Either that or use more air pressure.  Even with that little hitch, this was still a lot easier than what I've done in the past.

Hey J, love the pressurised bleeder!
I 'reverse bleed' but with a big syringe that I was given free with a bottle of Motul Dot 4 at my local. It's only about 150ml, but it's enough to fill the whole line on my CB400f (I have a custom braided line) and the master cylinder, which is off a Spada - ( same MC as on a CB250R). I guess it would cost about $2 to buy one at the chemist.
I hate to think what they use that syringe for medically...ouch!

I did build one that I saw on the net a few years back. It was simply a jar with colored water, 4 tubes that ran up a board and back down to the engine. It worked good. My shop is heated with wood so it goes below freezing on most winter nights. So I decided to fill it with antifreeze. Next time I used it I made the mistake of reeving the engine and closing the throttle. It sucked antifreeze up the tubes and into the engine! Not good.
Incidentally, the board these tubes ran up was 8 feet long.

I now have the style filled with Mercury and it does a nice job. What is really nice about this style is that you have the tubes for all four cylinders mounted side by side so it's easy to get them exact.
I also acquired a couple of the style that you hold over the carb throat and read a small ball that rides up a tube. These also seem to work good but the best is the mercury, in my opinion.

Here are some pics of a carb balancing tool I built with some aquarium tubing, "T" connectors, tape, a paint stir stick and some water dyed with food color.  I have less then $5 into it so far.  I haven't used it yet as I'm trying to find the right nipples to screw into the vacuum ports.  Anyone know where I can find some nipples with 6x0.8 threads?

[mwohlenhaus]

you wanna screw silencers onto the ol nipples?!?! seriously though, I have no clue.  could you use a presse in tube made of brass, or something to that effect?

[OldSchool_IsCool]

Hmmmm I wonder if the valve fittings from the kit with the T connectors would seal tight 'nuf.  I'll give them a try!

a friend of mine had sticks with no adapters so i was looking for a hardware company that could supply 5mm to hose barb adapters.  my friend found the adapters before i ended up doing it, but they said they could order them from a company called airpro "in europe."  ive never heard of an airpro that makes brass fittings.  they also said they would cost $4.20 a piece and the next order was going out in two weeks.  so that would screw up your low-budge effort.  the place i found was called maryland metrics, and you may have a similaar hardware source near you.  hopefully they can get them to you cheaper and faster than maryland metrics said they could.

you are right, they are 5x0.8mm nipples.  See this thread.

It wouldn't be too difficult to take a 5mm bolt, cut the head off, and drill a small hole through it. Just be sure to use a bolt that isn't threaded all the way to the head so you will have a smooth surface to push into the tube.
