So I have yet to buy the GT ….was planning on tomorrow but what is the talk about talk engine rattle? I really like the bike at first sight but I also don’t want this to be an impluse buy. I still have my 2021 V1K so I am not bike less
Any thought of the noise / concerns or just it just sound like crap??

thank you
Ray

It’s fine. I don’t really notice it for more than a few seconds on hot start

it’s a design change. People are positive it’s cam tensioner and low and hold it’s a new design change on our model.

woildnt worry about it. Many models do same thing. BMWs etc

So far it is just a start up noise and not all the time hot or cold. No failures reported to date. Even the naked bikes which were released in 2021 with same engine seem to be doing it as well.

my 2022 does.it sometimes for a few seconds on a hot startup. not in the least concerned.

sorry I double posted, on my computer it didnt show the picture, but now it does. but whatever. more the merrier

It always makes me wonder why...they update a part that has zero reliability issues, the k7 tensioner is foolproof....?

 

[FreePenguiny]

is it possible when they changed parts, that they needed to change the cam to accommodate?
maybe the cam didnt allow old tensioner to work

For what it’s worth, my 2020 Katana makes this noise as well. The cam chain noise happens for ~30s during startup and goes away later.

I wonder if the katana got the cam tensioner before the 2021 model did. just a silent update

The basic engine block hasnt changed, they have changed the camchain guides, that may require an updated tensioner, the camshaft itself wont affect the chain tensioner, well not untill running very high lift/duration cams which require very stiff valve springs, ( usually a manual tensioner is then use) it would be of interest to compare the mting flanges of this new one to the old, then it may be posdible to just revert to the older proven tensioner

I haven't had any noise from the cam chain at all - not even for a moment. I've only done 800km though so maybe it'll happen later.

As temporarykiwi has noted, the only differences I see between a 2018/2021 GSX-S1000 models are the cam chain guide and tensioner guide
Interestingly, 2020 Katana has the same guides as 2021 GSX-S1000

I don't think the noise is worrisome as historically Suzuki GSXR bikes always had timing chain noises during startup.

Mine doesnt make any camchain noise, the pre k7 tensioner had that fault

Mine suzuki gt 5500 km.started with this noise att 1000km .never sounds Cold. Or if l let it rest four an our it is silent. only att start up hot The noise vill be Therese four 10-15 sekunds

same here. I think I started noticing it around that time. but I dont typically do many hot starts so maybe it did it sooner I just was unaware

at least, if this ever becomes a recall, we will all have it repaired andit seems every bike has been impacted by this sine 2020 katana on.

Since this sounds like it has been going on a couple years has anyone spoke to a dealer about it ?
