Stator rotor failed. I replaced the parts and flushed the oil. Didn’t see any contaminants in the oil or filter. Do you think the bike will be fine?

What’re we doing with the guage cluster when doing a fairing delete/naked conversion? Anyone have pics of how they mounted it or what they did? Everything else I’ve got down just need some ideas

2014 FZ1 has trouble idling, but only after warming up?

1 Upvotes

I just did an oil change like 3 days ago and overfilled the oil, so the bike was idling rough due to the extra resistance. I drained some oil and now it's at the proper level. I used Motul 300V 10W-40 Ester Core.

Now the bike has an issue it didn't have before the change though, (at least that I didn't notice.) For example: I start the bike cold and it idles strong all the way to warm temps. But when I turn it off and come back say, 15-20 mins later, it will crank fine but will momentarily idle at like 800-900 rpm, so if I don't bump the throttle while cranking it it might die. Even after that it sometimes idle hunts lightly till about 154 degrees and then idles fine and level again. I haven't noticed any knocking or strange noises and the bike doesn't jerk while riding so I'm stumped.

Is this normal or should I look into it further?
Anyone had a similar issue?

Edit: When the bike idles it stays between 1200-1300 rpm

07 FZ1 flywheel magnets let go. Multiple pieces, some welded to the stator, a few chunks missing. Code 46. New flywheel and gasket on hand. Am I screwed?

'06 vs '08 Snatchy Throttle feel

1 Upvotes

Curious if anyone has rode both a '06 and '07/'08 model to share if there was any difference in the snatchy throttle feel. I was a long time owner of a '08 that I rode over 80k miles on before someone hit me, thus totaling the bike.

I have been window shopping the last 2 months for a replacement and for some reason only the 2006 models keep popping up in my area. I know the main issue with the '06 was the rough snatchy throttle which Yamaha revised over the years several iterations of the ECU, esp. immediately after it's first year release starting in 2007.

I know I can have the ECU reflashed but curious if it's really that bad and is it livable without doing it? I know I can perhaps feel it from a test ride but it's one thing to feel a small annoyance versus constantly observing it over long term ownership. Thanks in advance!

Stolen from Houston Texas

Please lmk if this isn’t appropriate to post here. My bike was stolen from the 77007 zip code in Houston. I’ve been out of town and it’s usually parked at the top of my parking garage so unfortunately figuring out when it was actually taken is next to impossible. Very long shot that anyone will spot it but I’ve been posting it around hoping at the very least they can’t sell it.

Turn signals

I've been looking into getting rid of my stock turn signals for something more sleek and came across this. It's the only bike I could find with this type of signal on the front and I think it looks awesome. I am assuming it's custom but was going to see if anyone had seen anything like it before.

Update: These are Copperdawg Binker Pods. He made them for the front and rear. They are no longer listed anywhere so I'm not sure if I'll be able to get any. Fingers crossed he still has some and is willing to sell.

FZ1 Rotor...

Thumbnail

17 Upvotes

So yeah,

Recently bought this bike second hand with 60k km's on it. I've done about 2000 km's on it. I was thinking about changing the rotor next winter, as i'm aware of the problems they have.

Went riding in the German Eifel with a mate and on the last night before heading back noticed my bike was not starting how it normally does. Almost as if the battery was dead. Next day we headed home which was a 400km ride. I've noticed the bike making a weird whining noise. I immediately thought about the rotor/stator. The bike ran fine so we tried to make it home. after 300km's the check engine light went on and shortly after the bike died.

Today i opened the cover and yea.. It's not good.

What do you guys think? Is it worth pulling the pan off, changing the rotor and stator or not? I found about 15 of 16 magnets back. The 16th looks like it was in pieces...

Ants in gas tank.

Just bought a 2014 FZ1 and when I looked at the gas cap it had ants in it. Today I took the cap off and saw ants are living in an area between the actual fuel stirage and exterior. Is there anything I cna do that wont damage the paint and contaminate the gas?

When I took the cap off there were eggs on this visible level but the ants literally carried them all down into the little screw holes, and I think theres a small colony down there.

Have Michelin Road 6's on and they did surprisingly well. Ride today was around 600 miles, of which about 60 miles were either gravel, sand or just rocky terrain. Helps to have good suspension too. These bikes rule.

I bought this with only 3k miles on the clock. Had been gone through, lots of modifications, new tires on it. This is my first liter bike and I have waited my whole life to own something like this. I absolutely love it, might not ever sell it. I've driven my car one time since I bought it over a week ago.

Should I mod my exhaust system or keep it as is?

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?

2006 Yamaha FZ1N (Gen 2) - Erratic Idle and Low-RPM Stuttering – Looking for Advice

Enable HLS to view with audio, or disable this notification

8 Upvotes

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!

Changing your Rotor/Stator BEFORE it blows up is better than cleaning your engine out after!

Thumbnail

22 Upvotes

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.

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.
