Installed a PC III this morning... man it's amazing to see those displays turn when you turn the throttle My two gadgets were talking and it was great :P
loaded the standard map for scorpion exhaust. Seemed to make the engine smoother and take out the low-rpm reluctance. Overall good fun on a morning ride

Then changed the oil & filter this evening, lubed the chain... gear shifts are again like butter.Washed the bike clean with cleaner and hosed it with water.

But later took it out for a 20 miles ride or so and it started having these pulsations in the exhaust instead of a smooth rumble... Right when I changed from engine braking to slight acceleration -
while trying to keep constant speed on uneven terrain, at a certain power point while changing between soft acceleration and deceleration.

The puttering/sputtering goes away when I take it to higher rpms (>5k), but if I try to speed up when it's sputtering it seems to really bog down for a second. Once I almost felt the engine shake due to uneven firing.

Could this be the PC III messing things up? I've had some mileage problems and then slight low end power-shortage problems for a while now so I'm inclined to think that the PC III is only precipitating something thats already a problem.
My exhaust also strongly smells of gas while starting the bike... along with some white smoke... this is before and after PC III

Sorry for the long post. I could have probably just said something like 'A cylinder is not firing' but I wanted to give more symptoms...

What to do?

 

Oh and the bike is at 15k, I've done the 12k service myself including changing plugs, air filter. I checked valve springs recently (or thought I did - basically opened the airbox, turned the throttle and tried to put pressure on each of the butterflies to see how it opens/closes... seemed as it should be for all)

Thanks guys

 

PC's are known to cause some problems to people for some reason. try unplugging the PC and ride the bike around for a while. If problem's gone, yeah it's the PC. e-mail the makers about it, maybe faulty. If problem doesn't go away when you unplug it, then you may be in for a huge bill. You could be having much bigger problems than a faulty PC. Let's hope it's simply the PC.

update us when you find out what happens.

 

I'd blame the PCIII or you getting something wet. The Honda stuff works, the Honda Stuff always works, that is why I love Honda's. I'd blame the aftermarket stuff or you messing with something Honda did.

edit:
Are you losing coolant? White smoke can be a water/coolant thing. Was your oil 'milky' before you changed it? White smoke is never good.

 

Coolant level is same as it was months ago. Oil was darkened brown. Although 3.5 quarts came out and 4 went in

 

Just try a different map...the slip ons are all pretty much the same.

If that doesn't work it sounds like you may have some engine probs beginning.

If it's an F4i I can send you a kick-*** map. Flip me your email.

What??? I know a LOT of people that run one, including me and not one person is having a problem with it. Do you have one? What do you base this statement on?

Make sure you have it connected properly and have a GOOD map in it. That means getting it tuned by someone that knows what they're doing. The wrong map will make it run BAD.

 

You probably have the wrong map for your bike. That is what is causing your bike to run like crap.

 

I have a scorpion slip on so that's the map I downloaded... dyno-tuning will be more $$$
