Bar levers clamp via pinch bolt on the lever perch. I think 10mm socket cap on bottom or top.
Just look. You'll see.
Alright. Thank you!

Any updates???
Hi, I've been lurking for a while and thought I'd get out of the shadows and say hello! I was a bit frustrated with the vibes and hard seat of my FZ6, and tried selling it at a bike shop in the city, but it didn't sell. So I'm thinking maybe I'm just meant to keep the bike.
The engine vibes have concerned me for a while now, and are noticeable more on hot days. Not sure if it's just the frame expanding, but I've torqued all the engine/frame bolts down to the correct torque. After spotting the spark plug cap thread I tried it, as well as a full service- oil/filter, coolant and brake fluid, and also I remoulded and added more foam to the seat.
I tried taking off #4 spark plug cap off the ht lead but found it a real pain. I checked the other leads and they all felt tight. I'm tempted to try again by taking out the battery and airbox. The new spark plugs have made a difference low down but it still vibey up high (7k upwards).
I still love the Fazer even though it's been 9 years since I bought it. It'd be nice to be able to nail the engine vibes. I'm pretty sure it's the leads and not the chain or wheel alignment. Has anyone modded the early model to have a coil over sparkplug design like the later r6s?
Anyway thanks to everyone esp FinalImpact, for all the informative threads! Cheers
WHAT OIL are you using and when was it changed last? I wouldn't bring this up but I dumped $30 USD of oil out after 1600 miles as the bike had weird vibrations, shifted notchy/clunky and may have been running warmer than usual. It was Mobil1 bike oil. 3 others have reported the same and dumped it also.
Try something DIFFERENT if that Oil resides in your engine. I have Zero complaints against Amsoil... Been running it since the mobil1 was dumped.
^^ It may explain your warm weather vibes!
I'd throw some cleaner in there. It wont hurt it, but you have to ride it for it to work...
Abstract but; in Au i think the CO values are directly accessible at gauge cluster. Take a peak and see what the offsets are. If there is huge desparity like >10 between the values. Pair them to the highest number and go for a spin. Report back....
Hint; C1 & C2 on mine are 0/0 but others have -15/+7 and other vales...
A compression test is not a bad idea either as it could indicate if a valve adjustment is due.
And this is 100% engine related and not chassis or speed related? Engine buzz would be all gears most/all speeds. Drive train or chassis would be speed dependent. I.e. tires, wheels, chain etc...
Have you done a TB synch?
A lot of my vibration disappeared after doing it. Still vibry but that's because I have no bar ends. I ride it for about 1.30 h before my hands go numb
Yep done several TB synchs over the years, with a Morgan Carbtune and before that I had a home made manometer, and they did seem to help a bit. Even trying the synch at idle and at about 4grand on the tacho.
I'll spend some time in the shed today and give everything a check over
The CO values did seem to help with the vibes. Standard values were like -18 and -3, it felt worse when they were 0/0 so I went back to standard. I tried higher values but still with that same offset and it seemed to help, so I'll go back and try some different combinations.
There's a really smooth part of road near where I live, speeds are about 90km/h along this section, and I've pulled the clutch and let the revs drop to idle, and it's smooth as silk. I've revved the engine in the shed and the vibes come back, felt through the tank, bars and footpegs. So I'm pretty sure it's down to the engine.
One thing I've avoided checking is compressions, just to see what state the valves are in. I've always been pretty particular about regular oil and filter changes, but often changed oil brands, generally getting semi synth from Castrol, Belray and Shell.
I've always been a bit worried about a valve job, because it's a big job, but that might be what's needed...
Anyway I'll go over a few things again and try a bit of seafoam.
Thanks for your help :cheer:
I saw you mentioned sea foam. I've used it twice on my bike before storing it and just after I bought it to clean the internals. I didn't really notice a difference post use.
Make sure all important nuts are torqed to spec, handlebars, axle nuts, engine mounts, drive train etc. You've probably already done this but I thought it's worth a mention.
Does it get vibry at certain RPMs or does it being at a certain RPM and stay through the range?
Do you have bar ends?
How is your idle?
In terms of fuel trims, the creator likely entered those -18/-3 values but dang, that just seems screwy to fuel 1&4 so differently than 2&3. In my mind I have a hard time thinking it could ever run smooth. That is a fair amount of difference. Snip
Yeah I'm not sure why there's such a disparity between the two CO values.
You'd think they'd be close, and I'm not sure how Yamaha would have tested it. Whether they rigged the engine up with a different exhaust header with O2 sensors in each of the 4 pipes and then tuned to suit CO emissions? But it's still weird having cyls 1-4 paired and 2-3.
I'll try again bringing the values back to 0,0, then maybe bring them up +5 at a time and do a throttle sync after. This is one thing I haven't done, I hadn't imagined they'd be linked but after thinking about it that could be the reason why zeroing the values didn't seem to help.
Next weekend I'll have a shot at synching the TBs and see if that helps.
I checked the resistance of the spark plug gaps earlier and they were all good, around 9 0r 10kOhms, but I didn't check the coil resistance. The sparkplugs are a new set of NGK CR9EIA plugs which I carefully gapped to 0.6mm, and made sure they were all firmly locked down on the spark plugs.
Anyway I better go for now. A huge Thankyou to you and everyone for all your help! PS- My daughters love your avatar of the pig in boots!
You have covered a lot of bases. All the Obvious stuff.
^^^ Thread title is a solid connection to your issues. I'd say you're on OK!
Good to know the bike was OK once. Snippity Snip
