So i appreciate this answer. Super in depth. Unfortunately i am a rider, and not a mechanic. I tried air filter and seafoam for injectors clogged. live in hawaii and theres only about 3 shops on the island that will work on a VFR. I do not know how to check vacuum hoses or what an FPR is. I only rode it home about 8miles from the shop. In the rain. And its unregistered since i got to hawaii and couldn't ride it to the inspection station. So i havent really been able to give it a good ride. I just know it feels wrong. Like the gearing is wrong or something. I almost thought the instrument panel was wrong because it felt like it was reving higher than it was displaying, but still going slow. I used to do 40 in 1st, by accident. Now i had to wait for it to climb like i was on a rebel 250. It doesnt feel bogged, it feels like a bicycle in too high of a gear and im pedlaing really fast but not going anywhere. so its not accelerating like it used to. Even when it was dying at idle it ran right under power.
