Default Re: TB sync issue

The later models had their tickover controlled by the FI so when doing adjustments with the engine running it will keep changing the tickover automatically and mask the real effects so this then has to be disabled during tuning.
As you havent got any codes it rather discounts any problem with the STV (I take it when you turn on the ignition they both go through their usual automatic full range movement check?) so that leaves an inspection inside the airbox and intakes...

Yes the STV go through the cycle. All of the balancing attempts have been done with the air box off But that is all okay

have you tried plugging the gauges into both vacuum spigots? e.g. take the back one off and put it on the front one and visa versa. to see if the read the same

are you sure your adjusting the correct screw?

have you checked that the link rods are not sticking?

I thought with the injection models that any adjustment on the throttle bodies and the engine management tries to compensate, adjusting the auto idle. That throws everything out of whack as you adjust, so the idle needs to be locked? I've never done it as when I looked into checking mine I couldn't find anyone except Suzuki with the tool / gizmo for locking the idle. I worked out (was suggested) my problem was actually the TPS adjustment and once that was sorted I didn't look any further into it.

yeh your right but only on the K7 onwards twin spark engines. The earlier injection engines have a manual tickover adjusting crosshead screw on the lefthand side of the engine which you just twiddle to get the revs you want. Its simpler but the downside is that you can stall the engine easier than the auto control type...

Yes swapped the hoses and gauges Evey possible way and it always shows the same result.
Yes definitely the correct screw.
I will check the link rods but I'm fairly sure they are fine.

The bike is not running as rough as the gauge would suggest, my only other thoughts is to try a different set of gauges but I'm confident that isn't the problem.
