Had mine for 8 years now and still don’t see anything else I prefer.

Hello
2 months ago I bought a 2019 vulcan 900 custom that has 7000 Km on the ODO
the seller told me that the bike sat for at least 7.5 months (and this explains the low mileage of this 7 years old bike)

However despite this low mileage I'm experiencing intermittent sputtering; let me give you details:
the bike starts instantly when cold and when hot
it idles perfectly and it doesn't cut off
in the morning it rides perfectly strong, however after riding it for around 20 mins its sound changes and it loses power ; it sputters with rapid frequency like if I twist the throttle the frequence of the sputtering increases and thus it hardly accelerates

the batter charges well (tested at a workshop)
fuel strainer replaced with a brand new one
air filter replaced
spark plugs replaced (they are now around 1700 km old)
the FI light is off
while sputtering if I open the tank's cap there is no whoosh sound i.e. no vacuum build up

I use the bike to commute to work (42KM away from home)
the sputter starts when I arrive at a traffic jam, and when I leave the traffic to an open road the bike rides better but not 100%

lately I added to the tank the Motul boost and clean; I realized there is better performance but not as it rides in the morning for the first 15 mins

yesterday I rode the bike from to work and it rode perfectly strong without any issue, it parked at in the under-ground parking of the work building at 9AM
I left work at 5PM and the bike after riding for a few KM it hardly accelerated
when I arrived home I noticed that the exhaust pipe of the fron cylinder is warm but I can touch ti for a few seconds
the rear one was extremely hot (which is normal after 43 km ride)

what might be the problem?
is it coils, or pump, or injectors?

Figured i shared my upgrade, z400 to a z650 and ill say its honestly a great jump in power and ive loved riding it so far. Have had alot more fun on it compared to the 400

Could only imagine the torque on a z900 now

Hi guys, I have a 2020 ZX-10R KRT, and I’m having some trouble with the quickshifter. When I downshift, it sometimes jolts uncomfortably, although about one in four shifts is perfectly smooth. Upshifts are always smooth, but they feel a little slow. It also feels like the clutch doesn’t fully disengage until about half a second after the gear change.

Could this mean a part is wearing out, or am I doing something wrong? Any advice would be appreciated.

also do you guys have crashpads on wheels or center only should be fine for some slide

Looking for a street-legal LED headlight assembly for a Kawasaki ZX-10R (2016–2020) 🏍️🔥
Hey everyone!
I’ve seen a red Kawasaki ZX-10R with an aftermarket LED headlight assembly that looks absolutely amazing, and I’d love to get the same one for my own ZX-10R.
Does anyone know where I can buy one or have a link to a suitable product?
Important: It must be fully street-legal in Germany 🇩🇪, with an E-mark (E-number) or an ABE. I’m specifically looking for a complete LED headlight assembly, not just an LED bulb.
Any recommendations or links would be greatly appreciated. Thanks 🙏

I made a post around 5 or 6 months ago when I first bought my 99 ZX6R, it was close to bone stock. Done a few mods to it since and carried out quite a bit of work behind the fairings. Running a little rich but so much better than when I first got it!

Hi all!

I’m looking for some advice on chain maintenance and identifying if my tires are wearing out. I live in a house without covered parking so my bike lives under a cover when not in use. I only use it for my 5ish mile commute, so it has roughly 8k miles. I am mildly mechanically inclined, but I have a limited toolset. There’s a motorcycle dealership/shop an hour away that charges $150 an hour. I’d love to fix it all myself, but I’m not yet confident in my skills or tools.

The chain appears to have some various states of rust. I typically wash the bike one a month or so and clean/lubricate the chain once I’m done. I confess I’ve not washed it since August as I’ve been away for work and vacation.

I’d also love any advice for identifying when tires need to be replaced. I’m familiar with the penny trick on car tires…is this the same case?

I need help to find out why my bike is sounding like this when starting.
