TB sync issue
 
Hi all,
My k6 650 has been running a little bit rough recently, bit rich and bogs down low in the revs.
I've set the TPS and been trying to balance the TB's.
This is where the problems start, the rear TB is reading way high, maxing out the tool at idle and the front is reading what you would expect on idle.
They are definitely not that out of sync and I'm sure it's not the tool as it does it anyway the tool and hoses are set up on the suction ports.
What would cause it to read so high?
I have to turn the adjustment screw right out to get them reading similar but that is definitely not right as it runs like S***.
Any help would be massively appreciated, I'm able to service/maintain my bike but when it come to diagnosing something like this I'm stumped.
Cheers

all I can come up with is that something is restricting the flow on the rear TB so that more vacuum is pulled at the test point. It would have to be something in the TB like the STV not opening properly or in airfilter/hose connection....

I've set the STV and replaced the hoses for new as that was my first thought.
Would it be worth trying at sync tool the sit on top of the TB? That's my only other ideas to eliminate it being something within the port?

Is it carbed or injection? Guessing injection as your avatar is a pointy. Are you using the tool that locks the injection?

I think the K6 was before you need the injection lock as it still has the manually adjustable tick over....
Gaz that flow meter is a bit of an an unknown and anyway it wouldnt cure the problem. What did you do to the STV as I thought they should be left as set up in the factory....

It's a 2006 with throttle bodies as mentioned above.
I have a Morgan carbtune this has worked perfectly fine before.
Not sure what an injection lock tool is? No mention of it on the sv650 service manual on throttle bodies sync process

Just thought is the FI light showing along with any codes?

Just made sure the valves heights are the same.

No nothing, nothing showing when in dealer mode either
