I bought a 98 VFR and the thing seems to be running rough until higher rpm. I ran 2 tanks of seafoam thru her and nothing changed. I ended up putting new plugs in and blowing off air filter not bad at all and found a couple vacuum hoses not looking right, so I plugged the one going to the diaphram the flapper is forced open. So I went to bike bandit and followed the vacuum diagram. Put bike back togather and the thing runs like CRAP and now the FI light is blinking. Any thoughts? very frustrating since I consider myself a mechanical person....
