i have a small story abt EVAP.

No word abt EVAP. But when we were tunin my bike i was behind the tuner to see what he doing in laptop, i saw on app options and he also ticked the box Disable EVAP.... and we unplugged evap connector
ok, dyno runs done, bike ecu flashed... suddenly on a dyno we got Check engine light..... tuner tried to read the code, reader showed no errors.... he suggests to run on the street for some kms, as it can be possible due bikes front wheel stands still.... errmmm ok, i did - nothing.
after several tries he gave up and called to kawasaki dealer friend to arrange me to come and check with their oem data reader.... i went to kawa service (lucky it was in same town, 15min drive), mechanic came with the data reader and first started to make visual inspection, he found evap connector unplugged - first thing he plugged it back, with words : you fccoking raaacers, doing shite to ur bikes then cry
then he he connected his computer, started the bike and voila, error gone, check engine gone. He said - dont do sh#t to your bike anymore, also ne didnt know i was just from ecu flash. he thought it was me - trying to fool evap system.
since that, evap in place, bike starts and runs fine. dunno why woolich software interface shows that option available, while they dont even list it on the web site.
just my 5ct
