accel pump question

[Kha]

Was wondering if the accel pump supposed to spray on all four cylinder with throttle? Checked mine today and it was only spraying on cylinder 2. Sprayed some air and only cyl 2 is showing air pressure from the brass nozzle.

Yep it sure should. It should spray a strong stream into each carb from the brass nozzles. This is what overcomes the lean idle condition off idle. The actuator should have a gap of .008 between it and the pump rod.

Now that I have the carbs off, what should I do to get it to spray all 4? I've clean the carbs and the accelerator pump is plugged.  The nozzle do 1,3,4 isn't spraying. Tried compressed air, only cylinder 2 nozzle got air coming out.

Well, I would remove any fuel links between the carbs first. The use a very small piece of wire, tiny strand of copper might do well enough, or a brass strand from a dremel brush wheel, and stick it into the opening of the brass nozzles. That should hopefully loosen that spot up. Then, if your air nozzle has a rubber tip that is beg enough, put it over the brass nozzle completely and press so it seals. Then blow and see if that helps.

When I got serious about cleaning my carbs, I got this: http://www.jpcycles.com/product/910-799?utm_source=PLAs&utm_medium=cpc&utm_term=&device=c&network=g&matchtype=&gclid=CPelt5ra_L4CFY1lOgodhSYAGQ

The wires are strong enough to bust through crud but not damage anything unless you REALLY jab it in there.
Carb sprays are not strong enough to really do the job and carb dips are a pain in the ass. So these work really well.

Make sure both ears for the accel pump are open. It looks like a mickey mouse head and there is a hole in each ear. Some aftermarket pumps do not have both holes.

Make sure it is assembled right too. The spring goes between the pump and cap.

Do I have to separate the carbs to get to the fuel line for the pump?

[Re-run]

No, you shouldn't need to. You could do the outside 2 if you want.

[Kha]

I can't spot the the hole in the brass nozzle. Even on cylinder 2 but I see it spraying fuel. I might end up just ordering that tool you suggested. I'll figure out a way to get good light on it tomorrow

[Kha]

I see it now.  Now gotta find a good wire

[Kha]

OK,  I got the nozzle to spray good flow 1-3 but the 4 cyl is still plugged.  Once in a while I'll see a tiny squirting through it but most of the time its plugged. Tried compressed air and carb spray but won't work. Tried cleaning the hole with tiny needle but still won't unplug. Will bike bike run ok with 3 spraying?it ran fine with 1 spraying before. Just some stalling problems off idle. Annoying but manageable.

[Re-run]

Are you using a can of compressed air, or an air compressor? Cans of air don't have the force needed. If you used a compressor, did you fit the air nozzle over the brass nozzle so that the brass nozzle is inside the air nozzle?

It will still stumble with #4 not working but it will be better than before.

I want to think the brass nozzles come out but I have never had to remove them so I am not sure. You may have to put on one of the fuel tubes for the accel pump, tube to #4 of course. Then spray cleaner in the tube and set the carb at an angle so the cleaner stays in. Let it sit for a few hours and see if it softens the crud up enough to blow it out.

[Kha]

Not a can.  Sorry, I used compressed air. Thanks re-run will try your suggestions

[Kha]

finally got all four to nozzle to spray. I think the PO broke something in the tip so I got a precision pick and an oscillating magnet/compressed air and it came off. Bike sounds so much better. No more stalling when blipping throttle from idle.

Never synced my carbs so what should I be doing next? First syncing and idle adjustment? or the other way around?

[TOOLS1]

Sync, then idle.

As tools said, sync then idle. When you do the idle, get either a shop tach or a dwell meter with a tach. It is much more accurate than the bike tach. Some don't bother doing it that closely but if you want top performance, it is needed.

[Kha]

Oh yes, top performance is what I seek. I'll be looking for that tach and do it ASAP.

Just went to a bike show at my town and all I see is Harleys. No vintage crowd at all. Make me disappointed.  Plus all the customs I see is paints. Well it was for charity so can't complain.
