If it is running great why would you want to do it? If ain't broken don't try to fix it.

I balanced mine and made it worse, so if its running OK leave well alone. I did do mine incorrectly with the adjustment screws and not the air bleed screws as it supposed to be done on this model though just to clarify.

Throttle sync is one where any deterioration will be very gradual so you may not notice any worsening. That said, running fine is a good indication they're at least in the ballpark.
Given you are at 28k, you should be due a valve clearance check in 2k. Presuming you have that done then get the throttle bodies done at the same time. It's a lot of the same tear down so will add very little to the bill and will want doing anyway if any valves are adjusted as valve wear is what throws the balance out most.

As I understand it, in order to check the throttle body synchronisation on the 2014 on models, the idle speed control valve has to be electronically locked with the Suzuki dealer tool, then with that any imbalance can be measured and adjusted out - can anyone confirm and advise on a 'home mechanic' workaround.

just done the valve clearances.do all the spannering myself but thought you needed the Suzuki diagnostic tool to ballance the throttle bodies or am I wrong

Rixington43 · « **Reply #6 on:** August 10, 2023, 15:32:27 »

Ah OK, it's possible the newer models require specialist equipment that the older ones don't.
If that's the case then I bow to those with greater knowledge of the newer bikes.
Did you have to change any shims?
If not then your throttle balance shouldn't have been altered, if yes then maybe it's worth getting them checked.

Dave the rave · « **Reply #7 on:** August 10, 2023, 15:34:10 »

yes 2 rear exhaust valve shims

so no one's had them done no one knows how often they should be done

Have you contacted Suzuki..?

Rixington43 · « **Reply #10 on:** August 10, 2023, 20:14:33 »

There's a workshop manual for an AL4 (which I believe is relevant as your gen should be 2014-2016), in the downloads section of this site. It confirms Suzuki recommendation is still check every 7.5k and you do need the diagnostic tool according to their method.

no havn't contacted Suzuki
was hoping to find some one who's had it done and thought they had done a good job
because I don't trust garages most of them are just after your money
that's why I do all my own spannering
so has no one had it done
no one

I was told by my local independent mechanic (used to work at the Suzuki dealership before it closed) that you need the special tool. She said she couldn't do it as she didn't have the tool.
I never bothered in the end and the bike runs fine.
(I think Appleyards or Padgetts is the nearest dealership)

OK thanks

Pete O Tube · « **Reply #16 on:** August 12, 2023, 12:46:56 »

Unless you've got something indicative of throttle body imbalance - lumpy or erratic idle - I'd leave well alone as it seems all to easy to screw it up (easy to check and adjust on the gen 1), there's quite a few with 2014 on, both here and over on the Facebook page, no one has complained of typical out of sync symptoms.

Dave the rave · « **Reply #17 on:** August 12, 2023, 15:23:51 »

I know what your saying but I do a lot of touring around europe
so was hoping some one on here had it done at a decent garage
would rather not leave it and get caught out some where in italy
I don't know enough about it to touch it myself
don't want to start ringing garages that I don't trust (and I don't trust many)
I will leave it for now see what turns up
cheers dave

Personally, you're worry over nothing.

Worst case, you'll have a slight fluctuation of your idle.

That's pretty much all balancing does ...

If it helps to provide reassure to what Kwackboy says, I changed my shims during one of the lockdowns c. 53,000 miles. I'm somewhere around 59,000 miles now and have had no issues with erratic idle or any other issues with the engine.
