Suzuki GSXR 1000 2017-2019 L7-L9 front EXCV / Headers valve rattle

Noticed a weird metal rattling noise on my bike only when the engine is in gear in low revs. It seems it's a common problem that the new front EXCV valve gets loose and requires adjusting from time to time. Just made this video for people to be aware how it sounds when it's loose. Check the service manual how to adjust it properly because it's tricky and it's not just one screw job which needs checking.

The cable developed some slack and you need to tighten it up, but don't do it like it says in the service manual and don't disconnect or loose the nuts on the cables for the back servo motor! Do these things:

1. Remove the left side front fairing to get access to the front EXUP valve

2. Spray some WD40 on the valve axle to break up the build up corrosion. That valve sticks when corrosion builds up. Move the valve by hand until there is no resistance and it moves nice and smooth.

3. Remove the EXUP valve cover near the catalyc convert.

4. Lift the bike on a rear paddock stand, start it up and put into first gear

5. Loose the nuts for the front cable only! Adjust the tension until the rattle is gone and that's it.

If you don't have a paddock stand you need someone else to hold the clutch engaged or put a ziptie on the lever.

I adjusted the exhaust valve rattle a while back. I feel I’m hearing a different noise now though. 16-17, 000 miles on bike.

Done a adjustment on the exhaust valve just down from my yoshi slip on and now after 13000 klms still sounds like junk heap when taking off and ridding it around town on lower revs

I have the same issue did you fixed it?

Mine sounds like a piece of junk and I'm over it
