Owenwil, yup, I have a simlar setup - stock vmods, K&N, but I run with my top on. When I first got the PCIIIr and stock v-mods, I noticed a significant decrease in my gas mileage, like down to 35-38 mpg. After I had my 10k service, my DH noticed I was belching black smoke out of my pipes on hard acceleration and I noticed a big increase in the "eau d'vrod." I don't know what the shop did in the10k service that made a difference, however.
I talked to our mentors here and called ChopperSteve at Mainstreet Motorcycles, who said the original 020 map was created on a bike running topless, which would account for the rich condition. So, after some angst, I ended up taking the bike in for a dyno tune and had the tech focus on increasing my gas mileage in the custom map. My custom map is SIGNIFICANTLY leaner than the 020 map, but I ended up with a satisfactory increase in power and much, much better gas mileage - still with the top on. My map would be too lean to run topless.
I don't remember if Chad is running with his top on or off, which we should know before you try out his map. And, if you try mine, you definitely need to keep your top on.
Both before and after I had my pipes v-modded, the bike would NOT run at idle. I took the ERC and doing all those low-speed maneuvers on the v-rod was QUITE a challenge trying to keep it from stalling out. It was idling just fine once I had the custom map done. However, I'm having some trouble getting my bike to start without a big hunk of throttle now, after my excessive bike clean-up job earlier in the week. I'll be asking for input on that in another thread here soon.
I have started wearing earplugs this season, only in part because of the deafening roar of the stock v-mods -- which I love. Mostly it's because I wear a half-helmet in warm weather and my ears don't like the wind all that well.
If I were in your shoes, I'd give Chad's map a try, as long as he's also running topless. If you want more gas mileage, you could put the top back on and use mine.
