5/2020- I captured the crash discussed below on my chin mounted GoPro- took me nearly 4 years to face it/post it- If you have yet to learn about high speed wobble and weave or Tank Slappers, take a look at this thread. The Dunlop vid is VERY good Motobricker info: https://youtu.be/z3OQTU-kE2s
8/8/2017 I was very very lucky- pause and read the speedo 78mph!!! Here ya go: https://youtu.be/dPqCEXP1neI
So I was reckless yesterday and dumped my beloved brick Betz....My injuries are only rash but im off work so today I'll start the disassembly for restoration. (May 2020- the 87 75S is parted out and replaced by a 94.
Post Script: March 2020 I acquired a much more racey Honda VFR 750F
It's funny, I have no freaking business charging around like I was but, in truth, my work a day life is dull, my drives exhilarating and my pocketbook too thin to cover track time. Friends who have crashed sell the bike and take up ...I dunno golf. I truly wanna get back on and do that again- that fast again I mean... Not that bike, that stupid way..but again, soon.
Post by: johnny on August 10, 2017, 08:59:53 AM
you are ok... thats the best news...
violent wobble or tank slapper aints no fun... it goes against instinct... butts staying light on the grips and off the brakes is key for the moto to right itself...
sounds like deep in and leaned over at that speed ... you were gonna wipe out no matter what...
proally caused by contact patch inputs rejected by motogyroscopic effect... may never know what initiated it... luck was on your side... soft ditch compared to trees or worse...
hope you getts it fixt up so you can ride that road very soon...

From the photos, it appears to me that beyond the windshield and turn signal most of the damage is repairable to a high standard. One of the plus sides to those incredibly heavy fairing panels is that there is plenty of meat there to facilitate proper repairs that will make them as strong as new. Hope you're back on the road soon.

My neighbour had a large Hardly Ableson delivered to his door,last Saturday.By Sunday afternoon he was hospitalised in a coma with a missing leg,his missus a broken arm and the other guy dead by being the head on motorcyclist.He's still in a coma.It has reminded me of how enormously lucky I've been sliding down the road on my ownsome,hitting nothing so far,but it's been a while now...

that emoji suits me today!!!
I value your generous words. Thank you.
went back and walked the crash site this am. It was eerie to stand in the sun, only sore and realize how fortunate I am today.
I took calls today from the insurance company, their adjuster and concerned friends...
Agreed Brick value on my policy is $2500, with a $500 deductible. So if say the salvage value is as the adjuster estimated- at $500 I would net $1500 for restoration bits etc. ....do I fix it or upgrade???or both.
For now i am too sore and upset to do anything more than park on my man cave couch, back to my brick, surfing YouTube on my Roku..
So this wobble: the contact patch goes away, the bars gyrate...is the Fluidbloc there to fight that like a steering damper Ive seen on bigger bikes?
If my drive line was a chain would I be less likely to tank slap?
its discouraging, I have three inop cycles in my garage in mid August. Maybe I'll dig into the on closest to road-able first for encouragement. Its true I can get this road worthy without the detailed resto done..winter is 90 days away!!
Tonight I thought about taking a friend's counsel maybe switching to 4 wheels for awhile..Ive been scouting for a late model GTI applied for a loan...Im 54.. no f ing business driving as I was...blast!!!
PS , Laitch, I need remedial training on this edit interface..Im out of practice of late.. I end up backspacing and changing fonts inadvertently.

sand... in the chee im a left tior track ridor... took some getting used to cause i was a outside inside outside ridor for a long time... then late apexing was my thing... outside inside only...
outside inside late apexing is the way to ride on public roads for us... until we moved to the chee... that right tior track and the space between the right tior track and the fog line is generally littered with fine sand and of course rocks because farm implements and trailers pulling the shoulder debris onto the road...
now i seldom ride between the right tior track and the fog line... have slipped too many times in the sand and feel the rocks can cause a tior puncture...
so its the left edge of the right tior track to the left edge of the left tior track for me... i just ignore the center of the right tior track to the fog line as if it was not road at all...
it took some getting used to butts have reduced chance of wrecking by a signification amount staying away from the sand...
now letts talk poo spreaders... and chip seal without warning signs...

Post by: The Mighty Gryphon on August 11, 2017, 11:06:19 AM
The fluid block is something I wonder about. It appears the design depends on the damping properties of a heavy grease in the steering head. What does that grease look like after 25-30 years? I have never seen a service interval for the fluid block posted anywhere.
I don't know the details of your crash, but I had a very close call about a month ago that was somewhat similar. I went into an unfamiliar blind curve on a farm road a bit too hot with my RS, and about half way in found it went into a rather drastic off-camber decreasing radius. I made a huge mistake backing off the throttle and tapping the rear brake to get rid of some speed. The bike instantly stood up and tried to high-side snapping the bars toward the opposite side, somehow after a couple of slappers in about half a second the bike settled down and I was able to exit the turn. I have no idea how I didn't wind up in the trees lining the edge of the road.
The high center of gravity with the fairing and a full tank doesn't help with stability in those situations. IMO, if my bricks have a fault, it is that they do not tolerate any deceleration once I am in a turn. At my age(on the doorstep to 70) with my reflexes, I am finding the need to slow down with my riding to keep me and the bikes shiny. Sucks...
Post by: Martin on August 11, 2017, 05:19:18 PM
-----------------
Sorry to see your accident and I hope you can get her back on the road. I've ridden lots of bikes starting from the late sixties. And some were highly unstable a couple of Kawasaki's come to mind the H1 and H2 and the Z1. I've had my brick for twenty years and a couple of times when it should of thrown me and started to tank slap it has pulled out by it's self. In my opinion I believe the 75's to be a highly stable bike with no real vices. I've however replaced the grease in my fluid block damper with Dow corning High Vacuum grease. RBM found a interesting video on weave and wobble, produced by Dunlop he might post it. If you can't wait it could be possibly found on You Tube under the title Dunlop Wobble & Weave. And after thinking about it I believe the reason I've survived tank slappers in the past (mainly on Japanese bikes) is that I instinctively move my weight over the front of the bike when it starts to happen. The video suggests that you lie your chest down on the tank. I'm not sure if this has helped or I've just been lucky?
Regards Martin.

I removed most of the broken bits today the highlight being that -get this.. the front suspension was locked fully down. The bellows normally about a foot tall stood 6 inches- and on the center stand brakes applied the front suspension was locked and full down compression...wow. Case fairing off now I jacked on the sump, tapped the front strut with my foot and "kahhhfwoppp" (thats a chee tech term for the front struts springing to full extension).
I suspect the sliding slam into that ravine slammed it home? seems to transit normally.
Whatchu think?
internal damage? I've never swapped fork fluid but maybe I need to dig into the front forks. no bearing wobble, struts transit smoothly as pre- shunt.
So Ill post an extensive parts wanted in the other forum.
ps...with the throttle quadrant rotated back into place, I fired up the engine and it started normally.
so in sum several fiberglass repairs, blinkers, mirror inner fairing panel...handlebars OK. pretty cosmetic stuff.. Hizah!!
throttle cable is very sloppy, pulls a full inch outside the brake reservoir. I've read something about this problem. Help?
Shout out to JackGeiger for that terrific Cool Hand Luke quote. All brickdom would appreciate the wisdom of this great PL Newman classic.

1 I left pressures at max after a two up tour with my bride the previous weekend.
2 I had a loaded backpack far aft and loaded paniers.
3. I was upright and didn't know to lean forward over the tank
4. I was in the danger zone speed range above 70... I saw 78 on my gopro vid.
5. The un-weighting described in the forum post and staggered position of front and rear tire are very likely on the rising curve where I lost control traversing a big patch in the tarmac entering the rising corner...
6 my rear shock spring was dialed down tight, I'll soften that setting back to my normal one up setting.. too soft and my weaves in sweeping highway curves.

My biggest concern for you is the forks. You mentioned they were stuck. If the fork tubes are bent, it will expensive to replace. Then you have to wonder if the frame has bent, even a little.
Post by: Laitch on August 13, 2017, 05:03:31 AM
Have you decided for sure to restore the bike? I've also seen some posts you made about buying a different bike with the insurance proceeds. If I was in your position, I would buy another running K75s and strip the crashed one: keep some spare parts and sell others.+1
Post by: Rcgreaves on August 13, 2017, 02:41:48 PM
the price of used replacements paint and materials is more than the payout. I may walk away from all the fiberglass work u less the salvage quote is very low...the compressed forks suggest a disassembly roll on a flat table and reseal would be prudent with a pros assessment of the springs. Nobody commented how struts can lock down collapsed like that...worrisome

I wouldn't worry about them. If I had money enough to get a different bike, I'd get rid of them unless I wanted to build my mechanical and troubleshooting skill more than ride. Start negotiating with Gryph. He's been making room in his garage for just such an acquisition. :yes

Take a good panel to any auto paint dealer and have them match it. They will even be able to match any fade there may be in the original or have them match a shaded part for the original color.

I paid something like $60 for enough Mystic red base coat to do an entire RT fairing with enough left over to to do the rest of the bike. And they guarantee the match. Add in $15 for a quart of reducer and you're ready to go.
It's amazing what the paint guys can do these days. You don't have to let BMW or BASF screw you.

1) With the bike on the center stand, take off the rear wheel, final drive (being sure to support the swing arm so as not to tear the rubber boot) and swing arm and drive shaft (there's a bit more to it than that, but the steps will be obvious enough).
2) Take out the "brain" (computer) that lives under the saddle. Refer to your Haynes or Clymer to show you how to unplug the huge connector.
3) Put one sawhorse on either side of the bike, with the tops of the sawhorses parallel to the length of the bike.
4) Slip a 2x4 through the space in the frame where the brain was. Have someone help you place one end of the 2x4 on each sawhorse. In the process you will lift the center stand off the floor.
5) You are now free to remove the center stand and pull the transmission (especially if you put enough space between the sawhorses).

Both Android and iPhone have apps and automatic protocols to stabilize the orientation during uploading to websites, but they must be sought out and configured first by the user. I use the Gallery function here and am downloading images to a PC then uploading from it—never have image orientation problems in the process.

Please do include me. The twisting at Wildcat Mountain and the decent into metro Montreal WI is just about the best there is this side of NC or CH or the Rockies. The hollows of Lafayette Iowa and Grant counties are a treasure to behold.
Certainly consider zip 53554 as a waypoint for a coffee and or tools en route. Blessings

Mine was on a Honda 450. My femur was in several parts and I didn't ride for six years after that.
I've never experienced a wobble on the K. I had a mild one on my F and fixed it by leaning forward. Rechecking the tire pressures (rear was low) and it doesn't wobble any more.
Post by: Rcgreaves on January 17, 2021, 01:35:39 AM
I ride the same road often on the VFR and relive the whole scene in my head. For all the K's appeal, at 9/10s the VFR is stone-cold solid through this sweeper. Crashes leave a dent, this one, not so much.
I'm doing a lot of aviating of late and mindful that it's often a stack of oversights that lead a pilot into a place of danger: Met a fellow who succumbed to CO poisoning and lived to tell the tale. 8-10 ten solid indicators said his muffler was broken etc... on the K it was the lack of a "preflight" weight in those german named saddle bags I prefer to reference as french bread boxes...tire pressures all wrong.
Hard-won lessons worthy of revisiting. Greetings to all from the Chee where a COVID sale brought us a bargain GL1800. What a @#$%$#ing ride.
