idle

I've got a 2004 FZ1 that it seems is running rich in one cylinder at idle. Above 2000RPM-2500RPM the bike runs great, no power issues. Initially the bike was running very rich, carbs have been gone through and thoroughly cleaned, float levels adjusted and spark plugs are all new. Even after all...

Hi folks, my name is Liam, new to the forum and new to the Yamaha fz1N after converting from a Suzuki gsf1250. Hope you’re all good?! I am after some help and advice if possible please....... I’ve made a school boy error last night, I was trying to adjust my idle speed as it was a little on...

Hey all, new here, not to motorcycles, I was an FZ6 guy years back and am looking at a FZ1 to keep the F800GS company in the garage. The issue I'm having is the one I am looking at has a stuttering off idle and no power below 3k. I'm thinking coils, is there something else I should be looking at?

Last Week: Stalling off idle is back. Dealer partially cleans my EFI (carbon buildup), turns up my idle and sells me Yamaha fuel cleaner. I put a measured amount in the next seven tanks. Hesitation off idle "gone." He tells me to ride the bike HARD once and awhile. After my 1200 mile trip to...

It seems my idle is not as steady as it should be. Synced the carbs, set the tps, and even ran seafoam thinking the pilot jets could be clogged. Tach needle seems to hold steady and then maybe fall by 100 rpms then goes back up but this is not a constant cycle. I have a two brothers slip on with...

Overheating?? EDIT: Thermowax issue hopefully solved, now need help with overheating. Check last post below for info. Okay guys well my FZ was not wanting to start very easy when cold, it would take a tiny bit of throttle to start up and idle would stay around 1200 then it would be...

I loaded the Jondaddy Stage3 map tonight from Duke's map pack, started it up and it smells pig rich, plus the idle is all lopy. Took it for a quick ride and the first time I pulled the clutch in it stalled, raised the idle a little and it stopped stalling. The thing backfires like a goddamn...

I recently became the proud owner of a clean 2005 FZ1 with 22k on the odometer. I have some questions about it though having now enjoyed the bike for a week or so. First during a cold start is it normal for the bike to Rev to 4k then come back the idle on its own when it first fires? I usually...

Hey guys, New to the forum,new to the Fz1. Picked up a left over 2012 with 38miles on it. Just about to roll over 600miles and I'm having a few problems. Bike is stock other than a two brothers slipon and the removal of the front fairing. Takes multiple cycles of the start button to get the...

Anyone ever had the Gen II running fine everyday, then the one day while it is idling or low throttle is has a hesitation? I rode to work and the gym last night. Bike running great, like always. It has not had ANY servicing other than I do oil changes and clean/lube chain. This morning...

Hello All, Recently I have noticed sudden and inconsistent fuel mileage drops from tank to tank. I just pegged 27k running a PC3 USB with out FCE or ECU re-cal. One week I can be averaging 32-35mpg mixed riding, then upon next fill up I can barely manage 25. I'm racking my brain as to...

So I got a 95 KLX 650 in for carb work. It would run then die. I got it running but it seems to be overfueling at idle. Fuel screw all the way in (tried all the way out to 3.5 turns) Cleaned all jets, replaced pilot with brand new #40 (stock) Needle and seat hold pressure Slide opens with...
