I have the same bike, but can't figure the hose you mentioned. May you explain more, please.
That must be the vacuum hose to the regulator?

Yes, vacuum hose to fuel pressure regulator. I have read it does very little, so doubt that's the cause.

Cleaned sediments and mesh.

To answer above from another poster, all vacuum hoses on the IACV are attached to correct nipples.

Thanks, Lee, for the details. Will look around the cables slack to judge how is the reasonable bars extension. Not to get it wider and then cut to original size  :cp

Just been out to the garage, the Renthals I have are 800mm. That compare with the 955i bars at approx 775mm and the 800xc bars at approx 815mm.

 Renthals do come in different widths, from 740mm up to around 850mm according to their website.

Have you thought about some 800xc bars? There's a couple on eBay at the moment for under £50. (note the Tiger 800 bars are narrower than the 800XC).

Just an idea.

Are these Renthals same widtgh as the original? Thinking of a bit wider handlebar when riding off road sections.

Yup I thought it might be, but according to other forums it does nothing because the pressure differential is basically zero. So I think it less likely. The surging seems odd if it's a pressure problem, would indicate pump ramping up and down...

Some standard things that I'm sure you've checked...make sure vacuum hoses are on the correct IACV nipple. One of those nipples is intentionally blocked. Also, the hose that goes from the air box back to the computer should be installed. Lastly, does your bike have an O2 sensor delete plug installed?

Possibly also worth saying no engine warning lights are on.

I sprayed a bit of wd40 around the IACV to see if there was a leak there because the housing at the screw is cracked. Seems OK though. I also sprayed around the throttle body, where I could reach and the hoses once I fitted the new ones to see if they had leaks.

I'd be surprised if it's a mapping issue because the map has not been deliberately changed since it was bought, and I trust the previous owner on that one.
