problem 1: 'chokes' when idling about 10seconds after cold start, see video:
you can hear a 'tsss' sound 2-3 seconds in. (happens also with air filter and housing removed)
problem 2: (related to problem 1?)
when riding in 2nd or 3rd gear, mostly when colder, low/mid-rpm (speed does not matter, but mostly around 3rd gear, 40mph), entire machine 'stutters', it feels like something is braking for 1 second and the entire bike shakes a bit(like a sudden drop in rpm) and it keeps going and repeats within 5 seconds. kicking into higher rpm resolves the issue. I am aware that stryker does not like low rpm, but I did not had this before.
could this be an issue with the cobra powerflo? I did clean the filter...
or maybe fi2000 ? I tried various settings, and run 5/5/4 (from 2/5/4), which maybe helped a bit.
wondering if 91gas could make it worse (reading that 87 is the way to go, which I will do)
any advice appreciated.
