Ok, last night after working the numbers, I went back out to the garage for another take on it.

I set the needles to 5th notch, and the jets to 128/132 (right for my elevation). Now it seems to rev fine in neutral, and seems rather good all around.

AC really neuters out the air intake though! 21% restriction is huge! I did notice that when I had the beast out (stock form), that it had wicked acceleration, and then it started to flatline around 65 KPH, and really slow to rise above there. I found the same results in high and low range.

But.... with that restrictive intake, and 21% less fuel, then I'd be losing a lot of HP that would be required for higher speeds (when I finally would use the whole carb intake, versus part throttle).

I'm super eager to take it for a rip, but it's a little tough to gauge now with the snow on the ground. [img]i/expressions/face-icon-small-smile.gif[/img]



Alltoys: Do you run an aftermarket pipe? I'm just curious if so, which one, and how much louder is it over stock. I'm thinking the v-twin should be fairly quiet. I have heard a Raptor with that single cylinder 660, and a pipe about a mile away!

 

Wires,
I have my muffler drilled out with 12 1/2inch holes down through the baffles and the spark arestor burned out. it has a 2 inch hole in the end cap where it used to be around an inch opening very restrictive. I looked at the AC 650 it is very restricted with regards to the exhaust, it has a little piece of pipe coming out of the muffler. You can gain considerable by opening up the intake and exhaust. Your exhaust on the AC is different than what is on the Kawi, check to see what size the pipe maybe, on my P700 it is 1 1/4 in. I do not think there would be an aftermarket muffler for the AC as of yet but you can modd it to get better performance it will be louder not as loud as a FMF Pipe though.

 

Alltoys,

Thanks for the tip. I think I'll try the muffler trick.

I did look at it, and the muffler is fed with 2 - 1.125" header pipes, and leaves with a 1.125" opening.

A buddy of mine wants to set up a group of guys to dyno bikes, so I'd like to do the exhaust mod, and then see what kind of power she'll produce. I'm thinking much more than stock!

Considering they neuter in the intake by 21%, and the exhaust by 50%!
