Hey all. I recently picked up a 6th gen Honda VFR. Have an appt at Rob's Dyno to get it properly mapped in a couple weeks. It currently has Staintune slipons, Oxygen plug mod and PCII.
I have a feeling its running a bit rich, but thats just a gut feel. And it does have some odd FI in this 1 case: when cruising between 3-5k rpm for a short while. If I start to give it a little gas, nothing really seems to happen. Then all of a sudden the bike will accelerate with an abrupt jolt. This was happening quite frequently when in traffic and cruising around 40-50mph. (BTW - def. not the 7k VTEC kick...that is very distinct). So I figure a proper map according to real A/F will help sort things out.
I'm looking for breathing mods to make that may help tuning. I'll be removing the PAIR. Any other suggestions? Heading over to a VFR-specific forum, but figured I'd throw a shout out here incase anyone has suggestions. I may spring for a PCIII if it has benefits over PCII.
Oh, I already like the bike a lot. It has couple minor quirks, but a nice all-around performer. Thanks for those who recommended it in the "2-up" thread.
