New 2006 idles at 4200 RPM's HELP!
OK, now that I have your attention, I have a severe problem with my new VN750 with 286 miles on it. I'll try to explain. I started it up for a long ride this morning, (42 degrees) & after a good warmup, I took off. It ran like a Swiss watch for about 25 miles. I came up to my first stop at a four way, & it died. I applied some throttle & took off again. I pulled into a Wesco fuel stop & it died again. I then smelled gas. I restarted & headed out again. I got to my destination, & I had to turn the idle up to keep it running & it didn't want to idle very good. It sat there for about a half hour at my friends home. I started for home & things really went south. At highway speeds at about 50--60 miles per hour, it purrs along great, but now when I come up to a traffic light, it wants to idle at 4000 to 4500 RPM's! Sometimes it will just sit there in neutral racing at 4000 + and then sometimes it will slowly idle down to 1000 rpm's.
I pulled it into the garage this afternoon.....pulled the fuel tank, checked the tank vent, made sure the vent hose in the right ear was not pushed in too far & checked all of the hoses & fittings that I could get to. Everything looked OK.
I took it back out for another spin, & no better. When I shift gears, when I close the throttle, it speeds up between shifts (to 4500 rpm's). I came back home, & when I came into the drive, it wouldn't come back down to under 4500 rpm's! I reached down & turned the throttle stop several turns out & it idled down & quit. I then turned it in until I got a nice 1100 rpm idle, blipped the throttle a few times, & it sat there & idled fine. Now here is the kicker.......I then twisted the throttle up to 6000 & it wouldn't come down past 4200 rpm's. While it was racing at 4200, I checked the throttle stop & it was back against the stop screw. The choke is also closed & has a small amount of free play. The throttle cables also have a bit of free play.
It just started doing this crap today. I know it is under warranty, but I would like to find the problem myself as it is a pain to take it back to my dealer which is 60 miles away.
It also stumbles & misses a bit when taking off when I can get it idled down. It then smoothes out after 2500 RPM's or so.
I know for a fact that it is getting too much fuel at low speed. Why, I don't know. It does blow out a small amount of dark smoke when I grab a handfull of throttle, & the exhaust pipes are blacker than a black cats hiney!
I already had to take this bike back to dealer at 91 miles for a rear trans seal replacement! This is my ninth bike & first KAW, & probably my last.
Sorry this post is so long, but I wanted to give all of the info I could.
