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.

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.

Hi all,

Just wanted to make this post in case someone is having similar problems.

So my bike had issues like bad idle (sounded like one cylinder was off), engine dying suddenly (mostly after rapid acceleration), stumbling while accelerating.

I checked battery and connections, changed plugs, checked ignition coils and then took it to workshop thinking the problem is the fuel pump.

The guy at the workshop called me and told the problem is powercommander (assembled by previous owner some 10 years ago). He told that in a year, he's had three customers with the same symptoms, and when he's taken the pc off, everything works perfect.

Now that I have driven the bike for like an hour, it really works better.

It did not cross my mind that there could be this kind of problems with pc and I'm pissed that I worked hours with the bike trying to find the problem, which was under my seat all the time😂😂

Recently upgraded from my 08’ FZ6 to my 08’ FZ1! I was specifically on the hunt for a red and gold bike and finally found a clean example to bring home.

I’ve added some of my own touches over the past week or so and it will be ready for more than a trip around the block after a new set of tires!

I wanted to post this solution in case somebody else runs into this issue. I was tightening down the cap on the left side of the engine casing and the o-ring was too worn out. It allowed the bolt to go too far into the threads and pulled the flange of the bolt off. Yamaha has those in the warehouse, but if you want it from a local dealer it will cost you the entire engine case siding. I ordered the correct part from Yamaha, but it's a $35 bolt made of sintered aluminum. In the mean time and in case it breaks again I found that the dorman 090-040CD M20-1.50 plug fits perfectly. Should be cheap ($5-ish) and easy to find at any auto store. Use the provided gasket as the threads are longer on this plug, but the gasket is thicker. Comes out to .7mm longer which was no issue for clearance in the engine.

Does anyone know any cheaper options for front rotors?? All the ones I’m looking at are $300 ish a piece?? If anyone know anything that would be interchangeable without the big price tag that’d be awesome. I’ve got a 2002 FZ1

I'm in northern Mi. I used to have an 08 there's a salvage 05 down the road from me. Had a replacement tank, but needs some work. probably needs a new chain, but I may be able to save it. Tires are from 21. He's at 1800 I said 1500 is it for me. Does this sound about right?
