    The cap has coarse pitch screw inside that the wires core threads onto. When the wire is held and cap turned CW the cap should not spin freely on the wire. If it does, cut 10mm of wire, fan the strands 360 and thread the cap on...

    See sticky in Tech Section for details.... I'd start there, it doesn't cost anything....

    PS remove the two bolts securing the radiator to the chassis and let it rest on the hoses. It will allow room to work.
    Sorry to bother you with this again, just trying to sort this buzzyness out if that is possible as it really bothers the heck out of me to know that it can be better. Could the Frame Sliders installed on the bike be a cause for the vibrations traveled through the seat? Rear Wheel alignment and all engine bolts are at spec.

    General tune-up: Valve check due?, oil change, spark plugs, plug wires (trim back if loose on the SP cap, there's a whole topic on that)
    Exhaust header tight, not leaking?
    Throttle body sync

    After that I'm lost. My bike is a bit buzzy in that range as well, so I'm going to try to sync the throttle bodies today and see if that helps.
    Did the throttle body sync help with your vibes?

    Re: Buzzyness Observations...

    As the throttle plates open past 3k all the air is through the TB vs idle air plumbing so it would be unlikely tb sync helps.

    So this buzz is any gear, any speed, engine rpm related at or above about 5k?

    I did end up replacing the coils and wires on mine as I could not buy 7.5mm stranded solid core wire without buying a 100ft roll. In this case, the other end failed and it is glued and pressed into the coil.

    Anyway, it may not be the leads causing you issue but do not count it out as these bikes cam be smooth. It is not normal to buzz.

    Given the situation my next steps would be loosening the exhaust from the header collector on back.
    At the collector to frame, slip joints of the mid pipe, the mide pipe hanger, and the muffler section. Loosen all of it except the header flange bolts get it moving freely so it centers itself and does NOT move when the fasteners securing it to the frame are tightened. This can remove a layer of vibes. None of the mounts should be pulled off center or pulled into place by tightening. Basically wiggle everything so the hangers rest on the frame where they belong with Zero tension on them and tighten everything up. The goal is to allow the rubber mounted isolation components to do their job. If they are forced into place this induces exhaust vibes into the chassis. Make sense? To a lesser extent the same is true of the rear subframe, but Id be less suspicious of this unless the bike has been down. Has this bike ever been down?

    If no help, dump the oil and try a different brand. 4 of us here noticed increased vibes from Mobil 1 oil. Dumped it at 2000 mi and tried Amsoil. Very happy and no vibes throughout the whole season.

    The buzz starts at 5k and goes away at 5,5k no matter speed or gear. It seems to be running at its smoothest on anything less than 4k and anywhere between 6k and 8k. The heavy buzz under the seat and pegs seems to pick back up again after the 10k mark all the way to redline. I noticed yesterday that the mirrors shake a lot at the high buzz ranges mentioned above. Further, I can feel the same buzz when in neutral and just revving it at the same points while on the center stand. I will have to go in the garage, recheck all my work on the spark plug caps and re do the rear sub frame reset and retightening. If that dont work I will try messing with the exhaust. I will post results as soon as i accomplish these tasks.

    Thank you for the quick response and support through this endeavor.

    Re: Buzzyness Observations...

    Tackle the sub-frame and exhaust as one. One holds the other so moving the sub moves the exhaust.

    Has this bike been down to your knowledge?
    How old is the oil and what brand?

    Although a valve adjust and TB sync will help with the overall smoothness, they seem unlikely to resolve this issue with your narrow performance issues.

    I wouldn't hesitate to run some injector cleaner through it, even this seems like a stretch as an imbalance would not offer moments of wellness from 6k to 9k... this seems like harmonics vs an actual fault.

    I am happy to report that after re-setting and re-tightening the sub frame and after a short ride the vibes under the seat appear to have been greatly reduced if not all gone. It almost feels that now I have to hunt the vibes down in order to get the same feeling I was getting before even when just passing through the 5k rev range. Definite Improvement. They were minimal in 6th gear and nothing compared to before and I could only feel them now more pronounced when in 2nd or 3rd gear.

    According to the previous owner, a barn roof had collapsed on the bike while in storage a few years back, but supposedly it was all fixed under an insurance claim as he provided me with some work receipts from his local Yamaha Dealer.

    It started raining on me so I had to cut my test drive short. I will post an updated review of the repairs after a longer test ride.

    I am running Rotella T6 full synthetic currently and the oil is fresh on the bike. I intend of replacing it with 15W50 soon. I will work on the exhaust and see if that makes a difference next.

    In the meantime i feel that I owe some to you guys..Thank you

    Excellent and your welcome!

    I posted that earlier as I had the same issue after a 0 MPH tip over (engine not running-but a very hard hit to concrete)

    Enjoy!

    Re: Buzzyness Observations...

    Sorry for the stupid question but I am a noob. Which bolts are considered sub frame? After I got my exhaust install I was getting some vibrations which seem to have settled now but just in case they come back would like to know what to do. Thanks

    The lower bolts, for the RIGHT SIDE, just above the rear BRAKE MASTER CYLINDER (left side-same location),

    The top bolts, pull the seat. At / under the very front of where the seat would be (hidden with the seat ON) is another set of the SAME TORX bolts.

    Thanks Scott, for the detailed reply. So, I just loosen them up and then re torque them down to 40ft lbs?
