I am the owner of a new 2013 8 Ball, I bought it brand new last month from Hernleys in Elizabethtown PA. Ive been riding since I was 12, ( Ill be 24 soon). Raced motorcross, track days all over the east coast on sportbikes, you name it Ive probably been there, so I consider myself an experienced rider, as well as a Mechanic as that is my profession.
Id just like to get that out there so nobody thinks im new to this.
Within the first 50 miles of a brandnew bike, it shut off on me 4 or 5 times. All of them happen as soon as I pulled in the clutch to downshift. Just shut right off. I took the bike back to the dealer, waited around an hour and was told they found a loose nut on one of the circuits and hopefully it was fixed.
Around a week after that, it has shut off on me several more times, not even 150 miles on the bike yet. Again, each time it happened it was as soon as I pulled the clutch in to down shift. Back to Hernleys.
I took the bike back monday sept 30th. It took over 9 days to get my bike back, as I picked it up October 9th. They told me twice they didnt get a chance to get around to looking at it, and then we had to wait for a part.
I was told they replace the Idle Air Control valve and that, Duane, the owner wanted to talk to me. So we talked, and what he told me was this.
That they went ahead and replaced that part, but it was likely my fault the bike was stalling because;
I AM NOT SUPPOSED TO REV THE BIKE, AT ALL, AS IT CONFUSES THE FUEL INJECTION. DONT REV IT WHEN YOUR SITTING STILL, AND DONT REV IT TO DOWN SHIFT, JUST PULL IN THE CLUTCH AND SHIFT.
Seriously?! I cant rev my bike to down shift??? He said it as if it was a normal thing and no big deal.
Anyway I took the bike home, 15 miles later it has shut off twice, and it is now back firing a good bit, random pops, poor bottom end, as well as throttle responce.
Oddly yesterday while riding I ran into another Vic owner. Bought his bike from the same place, was having similar issues, and got the same story, DONT REV THE BIKE. I thought this was weird.
So today I called two other semi local dealers.
The first I called was not suprised to hear from me, in fact he seemed to know my story before I told it, and said they fixed 8 or 9 bikes, all that were bought from Hernleys within the past few months due to bad service and a rude owner.
He was familiar with my issue and told me that they had seen several fuel injector issues, poor seating of the injector, or bad orings on them. But he said there is no reason at all why I should not be able to rev the engine for down shifts, as we all know thats what you do with any manual gear box.
Also while my bike was at Hernleys the 2nd time it got a nice scratch on the side cover, probably from someones boot as they went to get off the bike. The owner "buffed it out", well guess what, the scratch is still there and he could care less.
So thats my story.
A brand new bike that runs like crap, serveral people from the same dealer with similiar problems and no help from the origial dealer, and were all being told, NOT TO REV THE ENGINE, like its a normal thing for these bikes.
Sorry for the long read, but has anyone had these issues or is aware of a fuel injection issue? This is a real low blow for me as I have a brand new bike that seems to be getting worse and worse with each mile.
My bike would stutter all most stall and at times stall if I blipped the throttle at idle.
I always blip the throttle on a down shift. It makes for a clunk less silent shift.
But if I let the rpm get close to idle then blip for the down **** it would at times stall.
I am surprised that if they replaced the idle control valve that it still stalls.
What I tracked mine down to was a lean condition for a split second during the blip. In other words you twist the throttle and lots of air is introduced but there is a lag getting a response from the EFI. So the engine stumbles or stalls....
I blamed the idle air control valve. This thing is an electric motor that opens an air valve to lean the air mixture while cruising. And to lean or richen the air fuel mixture to control idle speed.
I installed the Lloydz air valve http://www.lloydz.com/store/item_view.asp?estore_itemid=1000078
This stops or decreases the leanness caused by the Vic idle air control valve.
My bike has a much crisper throttle response. It doesn't stall any more. But I have herd it sound like it was going to stall. Sort of like a stutter or miss when blipped at adle.
I also added the Lloydz timing wheel and these 2 parts has given me a snappy throttle response and great low end torque.
The funny thing is when I talked to the dealer about this they said there were a few complaints of stalling and throttle hesitation just of idle. And they had good success by installing the stage 1 flash.
My dealer has a demo bike same as mine with the stage 1 flash. So I started it up and blipped the throttle. It didn't stall but was it soft and slow to rev. My bike with Lloydz air valve is much snappier. So I am glad I didn't wast my time with the stage 1 flash.
I know you shouldn't have to add aftermarket parts to get a new bike to run proper. But like you I never herd of such BS not to blip the throttle ....but my dealer told me not to blip the throttle also.... They are hiding a problem.......
The truth is the FI is too slow to compensate for fast throttle movements .
On my last bike a Suzuki c90 - they added a second set of butterflies in the throttle bodies. These butterflies would partially close at low RPMs so when you blipped the throttle the air would be limited until the EFI could catch up and dump fuel. Then they would open up and let full air flow.
Harley has cured this issue by using a ride by wire. The ride by wire opens the throttle slower than you would with a cable. That way they control how fast air enters the engine. This eliminates the big blast of air and the FI dumping fuel in a split second later..
