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
