It's pretty quiet, revs up nice but doesnt scream like a gsxr nor does it have a deep rumble like other 1k+ bikes. Not sure how stock it is, just bought it like this. Whatcha think i should do?

Looks like she wants to go out for a night on the town.

Hey everyone,
I’m looking for some troubleshooting help with my 2006 Yamaha FZ1N. I bought the bike recently and have put about 900kms on it since purchasing; it currently has around 28,000 total kms on the clock.
Lately, the bike has been struggling with an erratic idle and some noticeable stuttering at low RPMs. I’ve attached a short clip showing how the needle is bouncing around while idling. It doesn’t seem to stall completely, but it’s definitely not holding steady, and the stuttering makes city riding or starting from a stop a bit frustrating. The bike is fitted with a full Mivv exhaust system, but I am not sure if it was ever remapped or tuned to account for it.
Any advice on what to check first or if this is a known issue with this setup would be greatly appreciated!

Does anyone know where to buy front rotors for this ?

Fortnine is all sold out ?

And can't see to find them a available anywhere 🤔.

Canadian buyer, but also have an aunt in America if anyone knows of any spots to check out ?

AI is trying to tell me most suppliers no longer stock the parts for these ? Help me prove to Ai it's dumb and help me get my bike back up and running please 🤔🤔😎

That's all.

I’m going to describe the failure in detail for any riders who have experienced the symptoms and are looking for the diagnosis, and for those who have not yet done the RMStator swap. This will happen if you have original Rotor/Magnets in your bike at some point and the failure symptoms can vary a ton, this is just mine.

Was starting from a stop in traffic yesterday, when coming up through 2nd gear around 3600rpm I felt a jolt through the bike and it started vibrating heavily while producing a whining sound.

Both the vibration and whine followed the engine RPM while riding in gear and revving freely. I was around the corner from the gas station so I stopped to fill up as intended. After pulling out of the gas station the vibration was lessened, but it “jolted” again and the vibration was worse now.

Took the bike straight home, only a couple kilometres away, and shut it down. No misfires, no smoke, no dash lights or errors, no leaks and seemingly no power loss, but I wasn’t hard on the throttle or in high rpm’s trying to get it home to test that fully.

As you can see in the photos, the infamous rotor magnet failure is the culprit, roughing up my stator and its wiring pretty good in the process and ejecting 60% of its now powdered magnet shards into my engines bottom end. Parts are on order and I’ll be tearing into the clutch side and oil pan to manually clean as much magnet material as possible out, before flushing the motor multiple times to clear out debris.

Like many before me learned the hard way, don’t wait to do the swap. It took me 30 mins to take the old parts out with hand tools, so it’s easy to do! Gonna take a lot more time to clean out all the crevices in that engine with hope it’s good to go for the future.

TLDR:

Do the rmstator swap now if you have no records of it being done. It will fail, and you’ll have hours of cleaning and assembly as a result, if you’re lucky. Or a ruined motor that’s now a paperweight if you’re not.

i’ve been trying to fix this bike issue where it turns on but dies after accelerating it’ll stay on idling forever but once i accelerate it dies, i have it at the mechanic shop currently, i’ve replaced the fuel pump the ecu computer cleaned out the carbs checked the fuses and nothing has worked anything else it could be? it feels like I can’t do anything to fix it

Was wondering if anyone on here has the v35 side racks for the gen 2 mounted WITHOUT the topcase rack. I wanna see how the side racks are mounted with the "plx359kit" and see if its possible to take my bike there mount it and ride it home. Ive tried look online for pictures cant seem to find any useful ones. Thanks.

Can one/some/all of the mods ask whoever is the Head Mod if we can get pics in the replies? I'm trying to help someone with an issue where them providing pics would be extraordinarily helpful but they can't without making a whole new post because this sub doesn't have reply pics enabled. It'd be very, VERY helpful if the question asker could post pics after being requested to by a question answerer.

61,000 miles and still a blast

Hello all!

I am looking for simple modification for my 2007 Fz1. I’ve seen some post about r1 parts being swapped. I’m enjoying my back. Also, anyone got a recommended rear brake rotor?

Pretty sure it was unnecessary! Bike has 8500km on it, was hard starting a bit. Mostly took the carb stack out to drill out the covers for the adjustment screws. Figured I'd give them a good clean. I've gotten new carbs that weren't this clean. Well... Back to rubber on the Rd.

Hello all

What would you recommend as the best battery for the fz1? If it the Yuasa one, how would you get it into the battery holder? I tried it but the seat would not latch.

Edit: I’ve added photos with the new battery upright and laid down. Please advise.

Hey, are there any taller riders out there? I’ve had an FZ-1 for a while now, and there are two things that are giving me a bit of trouble.

I’m 185 cm tall, and after a little over an hour of riding, I start to feel pain behind my knees. The second issue is the wind hitting my helmet head-on, which makes it noisier than on a naked bike.

Has anyone lowered their footpegs, or can

recommend a wind deflector?

I have replaced tires on my 2015 FZ1 with a new set of Michelin Road 5, but I am stuck with the front wheel not spinning freely.

I cant figure out what am I doing wrong. When I torque the front axle at the required 72 ft-lb the wheel drags....

Any suggestions for me!?

Thanks , happy and safe riding to you all!

Hey all,

I unfortunately have been needing to park my bike on the street. I have noticed after heavy rain that there has been moisture on the wrong side of the fuel cap seal, essentially at the tank opening. With this my bike behaves badly until I push through any water in the fuel. I ride it daily and putting a cover on and off is a pain. What I can't find is a replacement seal, only complete cap assemblies which I don't need. Anyone found and changed theirs that could lead me in the right direction?

Hi everyone 👋🏻 Hope you're all doing well.

I have a Yamaha FZ1SA (2007) and could use some advice.

​

​

A while ago, I decided to repaint the bike myself, so I removed all the fairings and also disconnected the battery. Before sending the parts for paint, I wanted to see if the bike would still power up. Unfortunately, when reconnecting the battery, I accidentally reversed the terminals (positive to negative and vice versa). This immediately blew the 50A main fuse.

​

​

I got pretty discouraged after that and ended up having the paint work done professionally. When I went to pick the bike up, the painter had temporarily bypassed the blown 50A fuse with a thin wire, thinking it would melt before causing any further damage.

​

​

About 200 meters down the road, the wire melted and the bike shut off. I tried bump-starting it while rolling downhill, but it wouldn't start—just made a few gurgling noises. Since I was around 140 km from home and it was getting late, I called the painter, and we bypassed it again so I could try to get home.

​

​

Once I got onto the highway, I noticed the dashboard intermittently turning on and off, which made me suspect that the fuse holder or wiring had been damaged. I continued riding and even reached highway speeds without issues for a while, but about 20 km from home the bike shut off again while riding at low speed and hasn't run since.

​

​

At this point, I'm not sure what to do. Has anyone experienced something similar after accidentally reversing the battery terminals? Is there anything specific I should check first? Should I start troubleshooting it myself, or is this likely something that requires a professional electrician/mechanic?

​

​

Any advice would be greatly appreciated. Thanks!

To follow on from my last post...

Throttle bodies lifted up and end cover (over the linkage) off.

They don't move and reset on ignition on like they used to.

Should I be able to move them by hand? I can't.

Is the easiest option just to remove the flies?

What would be the downside? (Running original end can)

Or do I need to strip down and grease the linkage, or replace the servo motor?

08 FZ1

Now I have a few rides in, I can say I love this bike. It’s fast, comfortable, and good looking.

Still working on throttle control as my last bike was a Z400.

Lol I have to focus super hard to stay around the speed limit.

Asking price: 8k

Odo:3.5k miles.

​

Do you think it's a good deal? If so, what all should I get checked before buying. The seller says it belonged to his Gramps and he maintained it like an adult.

​

I appreciate all the insights.

Hi, I recently got my first 2009 FZ1-S and I'm very happy. The only problem is that the previous owner hit it from behind (damaged the rear wheel and tail), I've been looking everywhere for the tail piece and the side handles. If anyone knows where I can get them or can sell them to me, I would be very grateful. Thank you so much.
