Replacement exhaust manifold and now my bike vibrates!

[Sneldog]

As the title says, my GS1250 has had a new fuel pump and replacement exhaust manifold fitted under warranty after a series of error codes and trips back to the dealer.

Now I have the bike back, it vibrates so much through the pegs and seat at around 5500 rpm. It’s pretty uncomfortable and very noticeable. It absolutely has not been there for the past 4500 miles!

I’m a bit of a mechanical Luddite so any suggestion why this may have happened are most welcome as it is back into the dealers for the sixth time this Friday to ascertain what the latest problem is. Am getting a bit fed up of it.

Thanks.

Guess its rubber hung like the 1200. can't see them getting it that far out is touching on anything unless the bash plate is on it? make sure the manifould to silencer clamp is done up.... and indeed the silencer bolt itself...

My bike been bike to the dealer and has had the exhaust removed and refitted. The vibrations are still there at 5500rpm and it is uncomfortable with a tingling through the seat and pegs.

I have gone back to them and said this is not okay but am starting to feel that this bike is never going to be right. It is there ex-demonstrator so one of the earliest 1250's and it has had to go back for five faults since December.

Am not happy.

are you sure the cause is the exhaust?

if you turn off all electronics and carefully run it on the stand does it do it also?

I would put a fiver on badly flashed software, and as it takes them 3 hours to do it, it immobilises their computer, get them to do a complete software upgrade, I bet it sorts it out.

I am wondering if they have not screwed up a O2 Oxygen sensor when installing the new manifold, reason for my thinking is, I installed AF-XIEDs on my bike and had the exact same symptom as yourself, a few days ago, riding at between 4.5 and 5000 rpm at 100 km/h in 4 th gear, as soon as I changed to 5 th gear all was good, so I am certainly thinking it is about fuelling.
