Ok so I have the motion pro carb sync tool and I tried to sync the carbs now that I have rebuilt the carbs and resynced the valves and i got the bike up running and when i attached the carb tool it sucked the fluid up and out instanly. This was when i had it all hooked to the carb 3 for calibration of the tool. What could cause this the bike runs and i am using it but sounds like crab and drink fuel.



Please help i just want to make it purr once before I rip it all apart.



Thanks'

I think I would try to call Motion Pro Tech Support first, and see what they say. Might be helpful. I'm wondering why one would have to calibrate a liquid filled tool? :baffled:

I have only ever used the old "Carb Stix" tool. Uses Mercury. Have never had this kind of thing happen to me. :waving:

Are you turning all the adjustment screws counter clockwise first?

First of all you have to have the tool connected to 2 carbs for it to work.
Second, carb synch will not help the fuel consumption.

I have all of the screws turned out max. I will try motion pro support

You should not have messed with the screws until the gauges were connected. It will almost require a mechanical synch to get them close enough to start the fine adjustment. You can leave the carbs in the bike. Remove the intake runners and with a thin feeler gauge, the thinner the better, put the gauge under the #3 throttle plate and adjust the main idle screw to get a slight drag on the feeler gauge. Then set #1 with the screw between the carbs with the same drag on the gauge, then set #4 then #2. From there you can use the motion pro tool to fine tune.

as dave said, was it hooked to 2 carbs? if so there is a huge diffence in the settings of each carb. it happens.

Hope the liquid was not Mercury!! bad for motor, worse for you. I prefer the electronic units, no fluids.

The screw in question are for the carb sync gauge not the idol screw. But i like your point and i should of done this when i rebuilt the carbs to be safe. One thing they dont tell you in the manual I guess. I will check this out and see if it helps. Thanks for the info.



Oldnewbie it is not mercury thankful or else i would be really in trouble.

Ok, my bad. You can get a valve to put in the hose or just pinch it off with pliers or something until you are ready to adjust to keep it from sucking the fluid out.
