Reply To: GT250 EFI Throttle Body Synchronization
Thank you for the instructions Marcel.
Currently, my bike idles nearly smooth at the following settings:
Front TB: slightly open
Rear TB: closed
If I move either of these a little, the misfires start taking place.
Connected a manometer with the given instructions and the results were not satisfying. The rear cylinder was pulling significantly more than the front and upon adjusting the TB settings on the running bike to bring them closer, the running situation got worse. Still couldn’t get the manometer to match on both sides and the rear cylinder ended up sucking some of the hydraulic fluid and burned it off. I gave up at that point and just wanted to ride back home from the shop. Tomorrow, I am going to try again by eliminating the ISCV, taking vacuum readings straight off the cylinders, because the bike idles just fine with the two vacuum lines blocked off and ISCV bypassed. I will post an update after.
