GPz 750 Pt 3..She runs...

Sort of. So carbs were taken off yet again, and this time were stripped
right back. Removed brass tube that main jet screws into (once Id ret the
HBOL and discovered I didnt need a punch to do so), to find on two of the
four carbs that it was ganked up, and the little holes blocked. So, that
little problem being solved, carbs back on bike and a quick squirt of easy
start and the thing fires into life. Superb!

Now the glitch is that whilst it will rev, on releasing the throttle, the
revs take a second or two to drop back down, and then its a little stuttery
for a second or two (sounds like its getting ready to stall, but doesnt),
and then ticks over.

So where should I be looking next? The needle slides seem to be freely
moving up and down in the carb, but whereas Ive taken apart the odd single
cylinder carb before, these diaphragm carbs are a bit of an unknown
territory for me..

Where should I look next people?...

Erm... How? How was that little problem solved?

Very carefully with a can of carb cleaner and a single "hair" from a wire
brush. And a tiny piece of plastic. Hair used to poke most of crap out,
and then piece of plastic used to ream out hole (used plastic so didnt
damage the brass..)

Hmm... Not A Good Idea IMHO.

An air line is your friend in these situations.

many moons ago when I was a devil for foreign touring I ALWAYS carried
a butane lighter filler, even though I use a zippo dipped in the tank
to spark up, butane is absolutely ace for cleaning out carbs and oil
lines, portable air line, and the propellant evaporates, even shrinks
things temporarily if you have problems.

 

Well, an air line was indeed used, but the state these were in, just
compressed air wasnt going to move it. Some of the gunk was just nasty
black stuff, but some was verdigris type green stuff, whic wasnt going to
shift without persuasion....

I was *very* careful though...
