New Tool Purchase

Picked these up from ol mate Dave Kellett "plug plug" who runs a frame straightner shop off Moss st. Seems every time I need some rocking horse shit he comes through for me

There German and cost less than $200. Will test them out tonight on the ZZR.

The bodgie white paint on the knobs is my handywork. Always gotta tinker I do.

I have been looking at these, from my local wrecker- he is charging $140ish for them. They look quite well made. My mercury gauges seem to always break the glass tubes. I am on my third set of mercury gauges, which at over $100 a pop makes these look good. Apparently the hose connection into these gauges are plastic and can break, but you can get metal equivalents.

How does it work?

Well I did the deed tonight, a bit of constant tweaking with the knobs to keep the indicators from jumping all over the place but I was able to get them well in the manual's spec range.

Tubes are rubber and the gauges are metal, all fittings are quality too.

How does it work? You pull the rubber bungs of the tiny pipes that stick up from the little manifolds between the carbs and the head and attach the four hoses. then you run the bike at idle and tweak 3 screws between the carbs to adjust the synchronization between them all. So they all suck the same amount of air. One of mine was out by a fair way so it was well worth doing. Should have a tad more power now and run a little smoother.

How easy are the mercury guages to get? Been thinking of making my own from a link I found but if you can still buy mercury guages I want a set. Not entirely sure about the dial guages. They have to be a matched set or they won't work correctly. At least mercury uses gravity and you don't need to have your gravity calibrated to make sure it works properly.

Yeah there is a easier way misty meaner... its called EFI

get something called a "carbtune" it does the same thing as the mercury gauges, however it doesnt have the joyfull hazard of if you f*k up and give it a wristfull, you suck a few mg of mercury through your engine. That's 'cause it's got steel rods that get sucked up from their seats by the engine vacuum.

no adjustment needed, they all stay as accurate as the day they were made

. Used my neighbours ones a dozen times and never had any problems with them.

The ones you have just look bling

.

Carbtuning is synching the carbs as said before, so they suck in the same quantity of air / have the same air "vacuum", rated in inches of mercury, or in my case, inches a steel rod is raised

. having these off synch will vastly affect tractability, low throttle openings, fuel economy (as you'll always be trying to compensate for the "rough" spot), and all round smoothness, etc etc etc.

Anyhow, if your bike gets a bit rough off the line, definately worth getting em balanced.

That looks gorgeous. I just use a plastic tube and oil at the moment

So, efi bikes *don't* have manually-operated butterfly valves, then?

yes you gotta sync the efi donks too I'm afraid.

The two reasons people seem turn their nose up at the dial jobs is the "flicker" and doubt as to whether they are all calibrated to themselves. I'm going to get a 4-1 adapter to check the latter and a deft hand on the knobs takes care of the former. I was able to get the flicker down to under 1 division on the dial and the dial has 50 divisions.

I just took the bike out for a blast after last night's tune up and the difference is startling

Smooth all the way through the rev range, no more rough idle, and so quiet I can even detect a "new" little noise

But I think this one is ok, just the faint rhythmic purr of the rockers.

I got my set of carb synch gauges from Z-Power .. am very happy with them for the price
