Gilbert, AZ | Ronnie...a V-twin can perform like a 6 cyl Goldwing. I just purchased my Vision and am loving every minute of it. Working on the break in these days, and trying not to twist the right wrist too hard...lol. Anyway, back to the subject here. I also own a 07 Kawasaki Vulcan 2000 LT. I've added aftermarket pipes, an air kit and a PowerCommander. I have a good riding buddy with a 05 Wing. I can walk away from him from a dead stop or on a roll on. We've gone at it numerous times, and I've always come out on top. I'm not sure the Vision will perform as well because of the displacement difference, but trust me, a V-twin will perform...

Under the Rule of Jedi - Masshole | Just to add...
People have mentioned about what the engine takes in, needs to get out. This is true. And while doing air box mods does help, as seen in Lloyd's dyno graphs, I think some better gains can be made in the exhaust area. Sure level 1 pipes flow more than stock, and level 2 more than level 1, but you still have that big restrictor in the head pipes known as the catalytic converter. So you might not be getting the full benefits of the pipe upgrade. What would really help is a system from the head back.
I noticed this on my 06 KP after I installed a 2 into 1 with no cat.
True a 2 into 1 will work better than a 2 into 2, but still, it breathed better. |

Jasper, MO | Everything all of you are saying is true, I know. I know a V-twin Victory can run with a 6 cylinder Wing. My ole' Sport Cruiser would run even up with my buddy's GL1500. Then he went and got a GL1800. Game over. Now I have a Vision. Game on again. This time though, he still has a displacement advantage of 101 cc's and an 800 RPM higher redline. My only hope is to be able to produce more torque in the 2500 to 5000 RPM range than the Goldwing produces in the 2500 to 6000 RPM range. That's a tall order, but the graph of Lloyd's Vision tuneup looks like a real good start. If Lloyd's torque curve could be extended level another 500 RPM, we would be looking at 103 to 105 horsepower at 5000 RPM. I don't know if that's possible without a cam change, which would most likely give up some of the torque at 2000-2500 RPM. That probably wouldn't be good on a 900 lb touring bike. As soon as I recover from paying the sales tax and insurance I'll be giving Lloyd a call.

I agree, no matter what you do that restriction in the headpipe will be an issue. |

Northern RI | Lloyd just did my Vision in Myrtle Beach. With stock exhaust, stock air filter, VFCIII, and Lloydz new intake plate it posted 90hp and 104tq. Should see a nice gain with and exhaust and intake. |

That's the kind of info I was looking for. Thanks.
