Update from Suzuki on ticking noise at startup:

Subject: Ticking noise - JS1EK12D4N7100021

Hello ****: As to the ticking noise inquiry, Suzuki Motor USA, LLC. does encourage you to have the dealer take a look or listen to it.

This motorcycle does use an oil pressure fed cam chain tensioner adjuster. It is kind of like a shock absorber for the cam chain. Sometimes it can take a few seconds for it to “pump up” and find the proper tension for the cam chain. When it does this, it can make a tick sound, and this is normal. As the cam chain wears and stretches over the life of the engine, this sound can get a little quieter, or louder, depending on where the tensioner adjuster is in its range. Engine temperature, and oil temperature upon start up can affect this too.

We hope this information is helpful.
Lol. What they are describing is something that would occur during cold start. The gt doesn’t do that…what’s concerning is that it only does it on hot starts…

I told them it only happens on hot starts........ which is puzzling. Had a direct conversation with them. I think Debbie at Suzuki USA was just trying to be non-committal about it in her response from the tech guys. They know about it. I don't think they have a real clue, just guessing at this point because no one has had a warranty claim for an issue caused by the noise.
As a final note, One of my red plastic reflectors came off of one of the side bags, and they are sending a new one n/c under warranty to the dealer who they want to install it. I am going to put some locktite on that tiny little bolt before I go out again with the bags. Problem is, their bag supplier is shipping the box with the 2 bags in it with everything loose and the dealer has to assemble the painted to the non-painted parts, the lock holders, and the reflectors. In a separate box, they are sending the lower bracket that braces the bags. And in a 3rd box they send the locks which have to be installed and keyed by the dealer to the ignition key. The blue and the black painted pieces are interchangeable. They also said the reflectors on the fender extension are the same ones as the ones on the bags as a backup. Personally, I bought 2 sets of embossed stickons that have the suzuki S, one set in black and silver and the other in red and black to put in over the screw hole from ebay. They are only $10 a set, come from China so I bought to check them out.

I am experiencing the same issue, Although I think mine is almost a knock. I'm right at 4000 miles. I have sent Suzuki Several Video's of the noise. Waiting to see what comes of it. Being that I'm the Service manager I hope to get a quick response. When I started hearing the noise I looked up the tensioner and saw only 2 left in the USA then they go on back order, so I quickly ordered one for the bike. I have it, But I do not think that it will solve the issue. I'm betting its either the Counter balancer or Crankshaft. Love the bike. I hope this can be solved quickly for all of us...

as much as I enjoyed the GSXS …. I can see a SF replacement sooner then later

I like my GT but this knocking is driving me crazy....I don't think I'll keep the bike long...and the buzzyness through the bars, seat and pegs is not fun either.....****, my 40 year old Suzuki's are better. Plus the "Myspin" is a joke
I thought I had knocking but I don’t. Pretty quiet.
Sorry to hear that... I have not noticed the knocking yet and got around 3000 kms. Am I supposed to rev it up to a certain rpm before I can hear the knocking? So far I've only listened for it at idle.

I am liking my bike a lot, don't notice any buziness and I even like Myspin lol. The only thing I'm upset about is how long it took me to get the bike, and the side cases took even longer, suzuki ruined my summer plans. But as for the bike itself I got no complaints.
Over 5k now. Seems like the tick is less noticeable.
4900 miles and mine is no where near as loud as it was back in warmer weather days. I have it apart now putting on the Suzuki over kill heated grip package. Started it yesterday and about 3 hours they're on and left bar grip curing over night that is where I stopped yesterday. I need to fire it up and turn them on this afternoon and make sure they are working before wrestling that 10 acres of plastics and 100 push pins and over lapping fairing pieces back on. What a pain in the butt to have to check the air filter. If they'd just made it so that inner upper fairing piece didn't have to come loose to get at the front tank shroud bolts you could lift the tank like the old bikes. You do not have to remove the gas tank to install the heated grips as the instructions tell you to. Just use a prop bar that comes with a GSXR or used to come with them and prop it up on the neck stem hole.

You could have used this heated grip, it installs in 1 minute!

lol guess I could have. I like the smaller oem heated grip and the somewhat clean looking install. Few nit picky things with the suzuki kit but I’ll spare **** the ocd details. They do heat up quickly, don’t like that level 3 is the first level on. Seems kind of backwards to me. Switch is a little cheap feeling for $450 entry price. Time will tell I’ll use them. Also hooked up my gerbing heated gear plug and re-ran my gps and valentine1 radar power wire both I hastily ran without removing bodywork when bike was new. New Bridgestone T32s mounted up. She’s good for a few more miles. New tires were a huge upgrade!

Trevor - knocking on hot start up (putting all the info we have heard so far together) is the sound of the tensioner. It does it when hot, as the viscosity of the oil when hot, allows the tensioner oil to drain.

It's a peculiarity of this bike and I would suggest, it's of no concern - just like the cam shaft knock on your 40 year old Suzis.

As for the vibration, I agree it's very annoying. I can only assume that the new camshafts have been installed without recourse to altering other internal engine components, to match the new rotating mass.

I have 90% over come this issue with slight fuel map mods, adding extra fuel over the vibration zone (4,600 - 5,600 rpm) on the IAS and TPS maps (as per dark blue areas on the pics). Also turning off the O2 sensor (which is constantly trying the lean out the bike).

At some stage, I might even try backing off the ignition advance in these areas, to help reduce the ragged feel.

It's a 10 minute job to do this with the Woolich Racing tuning software. Find someone with the kit. You will have to pay about $100 to Woolich to install the tune on your bike.

I can't help you with the seat issue, other than to try using some cycling shorts that have extra padding. My solution is to follow my Dad's example, when he toured to US on a 1983 Suzuki GS1100G - a nice soft sheepskin.

Wow....that was very helpful! Thanks....as for the seat, I have no issues with the comfort as I have done 23,000kms since May on it....lots of long days in the saddle and no issues....I do have the GT optional seat...not that I hear there are any differences from stock.....my bum is pretty hard....lol
Cheers
Olá a todos, tenho uma gsx s 1000 gt, acabei de percorrer 1.300 milhas, rodei a moto de acordo com o manual, mas quando a ligo, ouço um som de batida do motor, alguém mais teve isso, como acontece quando está quente ou frio.
[/CITAR]
Tenho uma 1000gsx GT de 05/2023. Neste momento tem 7400 kms e já levou outro motor pois queixei- me do barulho infernal que fazia. Com o novo motor fiz mais 1100 kms, no entanto logo após os 400 kms iniciais o barulho voltou. Reclamei junto do concessionário onde comprei e devolvi a mota com muita pena pois acho a extraordinária.
