    My evap upgrade should be on the way! I was excited to hear about that remedy / upgrade. Also, I've made sure to adjust my riding style a bit (read that as higher rpms / more throttle / slightly more aggressive riding). I've only had one stall since I made the correction, and I suspect the bike just wasn't warmed up yet. I also let the clutch out just a bit as it seems to increase the idle rpms without actually engaging. It's a pain because of how heavy the clutch is, but I got the Oberon Slave Cylinder to remedy that. Just waiting on decent weather to install it. I'll be sure to check the intake boot as well. Thanks for the input!

    I haven't done anything under the air box cover. The only real modifications I've done are moving up to a 43t sprocket, and getting the Dean Adams Tips / ECM upgrade. I have the Oberon Slave Cylinder just haven't put it on yet. Anything else I've done is cosmetic (bar end mirrors / tail tidy). I've read a lot about the solenoid delete, but my understanding is that with a "race" ecm it's deactivated so there's no reason to take it out other than to save weight. I've heard its pretty hefty (just over 3lbs), but I don't ride fast enough for it to make a difference. I've also heard about zip tying something together on the throttle bodies so they don't get out of sync, but I figured that since I'm not riding it super hard (literally fastest I've been is 105 mph on the interstate) I didn't need to worry too much about it. What else is there that may help?

    Are you lugging it? are you RPM phobic? lol but a lot of people are

    IMO cruising at 4500-6k rpm is a normal and safe riding range. Its where the engine just starts making power, It's well before the power peak, but solidly in the torque curve. Anything lower is just too low in the RPM/ignition advance range to be smooth.

    If you are riding around in the ultra-low sub-4k rpm range you are risking chattering the bearings and the dramatically high cylinder pressures you're causing aren't helping anything either. Its a V-twin, but not a diesel (lol) and can safely operate for extended times at 11,400RPM according to the boffins who engineered and built it.

    Where do you cruise at?

    Hi Cooter,

    I was barely keeping it over 4k. Definitely RPM phobic at first. I was used to chugging along at 2k on my XB9s. But after lots of great advice and input, specifically from here, I've upped my general cruising rpms to the exact range you mentioned, usually staying around 5k. If they dip, I downshift. I do a lot more passing as well so I don't have to slow down, lol.

    When I was in the break in period I accidentally hit 6k rpm. I wasn't watching the guage, but I felt the bike just start pulling away from me. When I looked down it was just over 6k so I backed off quick. After break in I've had it up to about 8k....It's literally too fast for street riding at that point, at least here in Knoxville. "They've gone plaid!!" LOL
