I just got a FZ1 yesterday and the bike is in (almost perfect condition). When the bike is cold I can rev the engine just fine and have no issues. When the bike has warmed up to regular temp, I try to rev the bike and it dies immediately. From 1st gear it shutters a tiny bit too when warmed up. I just got this bike and know nothing yet of how it works and how Yamahas are as a whole. Can anyone help me find a solution to this?

I just bought a 2014 fz1. I have the manual but I can't find what type of coolant I need to buy. What should I buy, I'm at the low line on the coolant reservoir.

I just got an 02 53k miles, K&N filter, yoshi rs3 slip on, "properly jetted tuned carbs" according to the ad.

Below 4/4.5k rpm, particularly in 1st gear its stuttering / surging / and just running rough and weak with weird vibrations happening that can be felt through the handlebars. Once it gets above that rpm range, it becomes smooth and the power kicks on all of the sudden.

What could be the issue here? Coils? Battery? Spark plugs?

My rotor exploded like usual for this bike and I’m cleaning the bottom of the engine and oil pan I ordered a gasket but this little star looking bit came with and I’m not sure where it goes.

I have an 01 with 50k miles on it. Ive owned it since 28k miles. Unsure if the fork seals have ever been done. Got an appointment with a place to tear down both front forks and replace seals and bushings and put in new oil. $625 for both. Unsure if I am being taken for labor time, but at this point owning the bike for so long with no issues besides regular maintenance I dont really care. Wonderful bike and happy to keep it on the road.

Fun that I noticed when front braking was less than usual as it leaked right onto the caliper.

Anyone else have other long term bigger jobs they have had done?

Had my 02 for all of 3 days and already got pulled over for 101mph in a 55 when overtaking a car. Holy FUCK this bike is so powerful and fun. Couldn't imagine having a cooler motorcycle. WOOHOO!!!

Every now and then the red oil light turns on. It used to come on when I'm in higher 100'skmph And now sometimes, momentarily, turns on while it's idling. I've checked oil level and it's topped up. Is this a sign of a failing oil pump? Bike has 54k.

I ordered the gadget and was gonna check once it came but I got unlucky and it blew right before it came. Bikes got 31k miles and I think there’s magnets in my engine now any advice? I’m thinking of taking the exhaust off and the oil pan and trying to flush it with oil and do my best to get all bits out but any help will be appreciated

My 2006 fz1 is set up the same way Ivan did when he made the Ivan’s Eve flash, it has a full system yoshimaru and is tuned with the dyno jet. I just added the healtech quickshifter and I’m curious if this could cause any damage,( my rotor blew right after I installed the quickshifter lol) I believe my engine is ok and I caught it pretty quickly but it’s gonna take awhile to take the oil pan off and clean the debry of metal before replacing the rotor and stator and anything else that might have broken

I have a 2008 fz1 with about 85k kms on it. Located on Alberta. I have givi side cases (not pictured) and rear top case along with tank bag. I still have original windshield and seat. I'm thinking $4700 to $5000 would be good selling price. Any and all suggestions welcome.

I lifted the tank to check for a kink in the fuel line (found it) and while fiddling with the line, the nipple it was attached to snapped off the fuel pump assembly. I can't find a part number for just this bottom piece. Do I have to buy the entire fuel pump assembly to fix this? Anyone know of alternative fixes? I rely on my bike for daily transportation and cannot afford a full new fuel pump assembly right now (~$500 on Partzilla).

I have a 2002 Yamaha fz1 with a swapped 2005 engine the 02 engine blew up the first week of me buying it so I truthfully don’t know if this happened on both engines. On 1st and second gear it is full power all the way through, on 3rd-6th gear it has strong full power until about 8500 rpm then bottle necks and doesn’t have any power increase like it hit its limit, but I know for certain it didn’t, this limits the bike to maybe around 120mph. Any thoughts? Bike idles and starts perfect. I have new ngk spark plugs, new magneto, new battery, carbs cleaned. Exup doesn’t appear to be stuck. I have a new ecu because I thought maybe it’s the coils which I haven’t ruled out, when I tried to replace it with new coils it ran but then burned out my ecu so I put the old ones back. Fuel tank is clean with new lines, but haven’t changed the filter in my possession.

What you guys running got a 02 Do you use any additives?

Hi can somebody tell me if this is the water pump?

Hi, I have a 2004 FZ1 and those T shaped valve things seem to have crumbled and broken in my bike. Can't seem to find them anywhere online and mechanic says I need to order the entire set of carbs. Is there any other way to replace them? Thanks

I've got an '01, had it for 17 years, never a single problem, aside from the occasional dead battery or stiff EXUP valve. I had to store the bike for 10 months, and got it back around Memorial Day. Now I have an issue where the bike sputters like it's fuel starved. It happens randomly, and I thought it was because we're in a much warmer climate. It seems to clear up after a few miles, but the issue keeps returning.The fuel filter was ancient, so I changed it. No improvement, unfortunately. My next idea is to check the tank filter, and the spark situation. Anyone else had this issue? Not sure if I should focus on spark or fuelling. Thanks!

I saw a recommendation for the MoTech bags, but they are out of stock. Any other recommendations?

Is there a quick fix to this maybe some rubber seals between the fairings and screws ? Would it be the sides or windoshield fairings?

My mechanic had a fz1 told me got mad one day and ripped his off lol 😂

FZ1 N 2011 Spark plugs? These are my current spark plugs and for some crap reason I cant find the exact replacement in the UK! Any suggestions please? My bike is in India so taking the plugs with me. I looked up the non iridium ones and they have shorter heads with less threads?! Bizarre! Any leads would be highly appreciated! Cheerios

Not fully on like less then half did I fuck up to bad What can I do now ?

Hi guys, does anyone have or know where I cab get a workshop manual for a 2009 FZ1 at all please?
