Evening all

My carbs need sync'ing, and have read from stephens old posts that vacum guages can be attaced at a couple of points opposite the oil feeds on the carbs.

When adjusting the idle for each carb should this be done on the A and B throttle cable adjusters or the by using the adjustment screw on the linkage.

also, carb related, i removed the airbox tonight and removed the soleniod filter unit from underneath the airbox, there was however no sign of a filter, just a plastic cup type thing, is the missing filter a sponge or paper element? assume it must be like a disc, that can easily come out. Best place for replacement i assume is tyga or order through honda dealer?

cheers

excellent that andy, i trust the procedure is the same for mc22 carbs.

Some really good work gone into that manual.

Same principle I would imagine, despite there being 4 of them, and them being CV's!

Ha Ha Bit of a typo up there mc21 is what i meant!

it all all gets confussing when when you've gor NSR's and RGV's mc21, vj21, mc22, vj22 etc

YEah, it's those RGV's that are messing with your mind!

Yeah, pretty much the same for the MC21 and can also be applied to the MC18's and MC16.

The Later MC21 carbs have a "dimple" on the slide that can be used to visually align them, and all the other carbs can be visually aligned by the little crescent cut-outs at the bottom of the slide as they lift up and "touch" the top edge of the carb body.

Fine adjustment is then done with the air screws based on the venturi pressure measured with a vacuum gauge.

I have probably got a spare one if you are stuck, I have a couple of old airboxes kicking around.
They do have filter in, not sure if its sponge or paper.

hi paul

i ended up getting a new one from lings, but thanks anyhow, they have them in stock as it the same solenoid filter used on a honda nsx! its funny the 13mm m7 clutch basket bolts are also used on a honda mower!

bikes all done now, last job was tonight after a noticed one of the coolant hoses had a small cut, but thats all done. power run on the dyno sat.
