Always wanted to give the little girl a bit more jump in the rump but I'm worried that the net gain will be negligible. If I add a PC-3 and maybe open up the airbox will it be worth it in terms of more power or am I just going to muck up a bike that runs perfectly right now? FYI the bike has Boom Tubes exhaust and I've already swapped out my front sprocket for a 14T. Anyone do this on a 620?
My $0.02:
I have had the Dobeck and PC3, both were on my M620 w/open airbox and hi mount Termis.
Dobeck[didn't adjust factory settings]: easier running and starting . . . ran cooler, not much, during spirited rides, easiness of installation; higher fuel consumption >>> http://www.dobeckperformance.com/viewproduct.asp?vehicleid=465 (http://www.dobeckperformance.com/viewproduct.asp?vehicleid=465) [I had the TFI Gen2]
PC3: same as above :-\
I'd recommend, to have an exhaust gas analyzer if you would like to make any adjustments since, adjusting idle will affect other areas or pay to have it dyno tuned . . .
If you're comfortable spending on a PC3 and Dyno work, yes, do it [thumbsup]
Smoother, stronger, better economy, easier on the engine.
Open air box would help in the search for another few bhp, maybe a lighter flywheel to make it feel more eager...
It won't be that much faster, but a fun project [Dolph]
Agreed with if you can afford it, do it!
No 620 experience but added PC 5 and dyno tune for my 1100. It only added a few HP, but smoothed out the engine, starts easier, runs cooler but mileage went way down.
Lighter flywheel was best part of my 696 upgrade, that and electraeon quick throttle cam. Adding the pc v, exhaust, free flow filter and more open box top.. its a fun little bike. I even went back to 15t front since it was so smooth and pulled quickly up rev range.

those on my M620 plus the G2 throttle tamer made a ton of difference . . .
I will correct my first post, with the Dobeck & PC3 fuel consumption was almost as OEM maybe a little better, on longer rides, in city riding, was as I stated, worst
