    I think there is one bushing that gives trouble - but mainly to the Europeans because they actually ride their GTS's in the rain. If you keep it lubed it's not a problem - and the bearings are cheap anyway.

    The guy I bought this one off said people had called and lowballed him, using the cost of a new front rotor ($800) as an excuse. This one is barely worn and most owners don't seem to ride much anyway so that's hardly a good reason. Also, compared to an exhaust system or other major component for just about any modern superbike, $800 ain't too bad. Besides, it's not as if that wouldn't be the same concern for EVERY GTS and factored into the price/value from the start.

    Biggest "problem" to me is difficulty of access to the engine and ancilliary bits. Now that I've removed most parts of the fairing (cowlings in Yamaha-speak) and realized it's not quite the chore I had feared, that concern seems to be receeding.

    It seems that there is a Macadam 90 in the front, those were known to cup badly... There was only one thing you could do to avoid cupping, park the bike and forget about it :huh Michelin came out with the Macadam 100 shortly after that...

    You've got good eyes!

    The 13-year-old Macadam has gone, replaced by a 120 section Pilot Road 2. Noticeably quicker turn-in and generally lighter steering. It certainly inspires more confidence but the 80+ vibe is still there. I'm also noticing a very slight shimmy in the bars if I take my hands off at about 40mph.

    While having the front tire fitted, I had the shop check balance on the bare wheel. The wheel was about 1oz off and had a slight deviation at the rim (I'd estimate about 5 or 6 mm) but no runout or damage discernible. We checked several times to be sure, reseating the wheel on the balancer between each. It took 0.5oz to balance the wheel with the tire fitted.

    I'm going to pull the back wheel (which has an unworn 5-year-old Macadam on it) and check the balance on it before I start getting concerned. The vibe is very slight and I could certainly live with it but the bike is so smooth otherwise, I might be looking for a replacement front wheel if the back checks out ok.

    I've owned two of these in the past.
    They are a great bike.
    Loathed by the press when introduced, and a sales disaster for Yamaha but now a sought after rare classic.
    The problem in the early days was it's high price tag, and the fact that as a sports tourer, it wasn't a significant improvement over it's already ageing stablemate, the FJ1200.
    The fact that the engine was toned down to 100bhp from the original Exups (same engine) didn't help it's cause either.
    Just one thing to bear in mind.
    Most cosumables are still available off the shelf. but that front brake is unique to the GTS and not shared with any other model.
    The single front disc, is actually two discs welded together and the front brake caliper was borrowed by Yamaha from a car manufacturer and adaped to fit the bike.
    I know this because I was in the GTS club of Japan and spoke to one of the people involved in the project.
    Yamaha no longer produce the discs.
    Also don't crash it as the panels are also no longer produced

    Everybody talks about this unobtainable (or ridiculously expensive) front disc yet it doesn't seem to be a high-wear item. In the US I'm not sure most people are putting enough miles on their GTS's for it to matter much.

    Regardless, I am going to switch to kevlar brake pads as I understand they are much gentler on brake disks (rotors).

    Off to get the rear wheel balanced - See if that might be the source of the irritating high speed vibe.

    Unique ride.
    My 92 FZR1000 made it to 30,000 miles before one of center intake valves recessed so far that I couldn't get a thin enough shim to set it right. I checked it every 6,000 miles.

    The exhausts never changed in that mileage but the intakes and particularly the center ones kept getting tighter.

    Make no mistake, the front disc will need to be replaced at some point because as with any other vehicle, it is a consumable.
    I know someone who currently has his GTS laid up as it's failed it's annual road worthiness inspection, (MOT) on a worn front disc and he cannot source another as Yamaha now have none in stock.
    It's an issue but I'm taking nothing away from the GTS as a great bike.
    I've owned two of them over the years, and covered about 50,000 trouble free GTS miles.
    Well nearly trouble free.
    My water pump failed in France on a touring holiday but that could happen to any bike.

    Time tot ake the stocke rotor off the carrier, and have a machine shop emulate it, and save the CAD files. They could then become the only retailer of replacement rotors for the GTS.

    If I remember right, Shamu was raced by Brian Catterson of Motorcyclist magazine. It seems like he wadded it up at Road America during a Team Extreme event, but I could be wrong. Been a long time ago...:gerg

    It was also raced by Steve Lindsell at the Isle of Man TT.
    He came in 6th in the formula one main race in 1995.
    That year I took a trip to his motorcycle shop to see the bike, and it bore no real resemblence to the factory bike.
    For a start the original engine had been junked in favour of the YZF750 lump, and the frame and front swing arm were specially made.
    In fact, virtually nothing of the original GTS was present.

    The rear wheel had a couple of ounces of weight on it at almost exactly 180 degrees from where it needed to be. I expect she will be even smoother now and hope the irritating vibration will be entirely gone.

    Ouch!

    Still, if the main frame is OK, that could easily be turned into something nice.

    For the first time in my long history of motorcycle ownership, I do find myself concerned about maintaining originality. I added flashing LEDs to supplement the brake lights and went to great lengths to add the wiring in a fully-reversible fashion rather than my usual cut, solder and drill holes approach. Decided against several GPS mounting options for the same reason.

    Regards that picture of the crashed GTS.
    Under that upper fairing, is a very elaborate soft metal subframe onto which the hideously complex wiring system is intertwined.
    That will have been severely bent out of shape, and is not replaceable.
    I know because that's what happened to mine after I dropped it in my driveway.
    It could be straightened, but that's going to be one hell of a job.
    The only hope for that bike is possibly some sort of streetfighter project etc.
    Or get another and use that one for spares.
    This is what we need to bear in mind when buying this sort of bike.
    Manufacturers are only legally required to offer spare parts for a bike for up to 10 years are it has been discontinued.
    After that, it's a question of luck.
    The exception to that are BMW.
    I doubt there will be anything left at Yamaha now for a bike which was produced in a very small number.

    Nice little 75-mile afternoon jaunt round the back roads... The high speed vibe has indeed vanished.

    This bike is smooth with a capital Smoo! Loving it!

    Got another IBR plate in yesterday. Need to order an ADV sticker for that big hugger.

    Nice day out by the (super high) Mississippi river back in June

    She is now out of commission while I rebuild the seized ABS unit. Almost all stripped and cleaned but currently stuck trying to work the pistons out of the pump units. Scratching my head figuring out what to try next.
