RCG, Glad you're ok....speed wobbles are my least favorite "fruit-of-the-loom-mandatory change" moments.

Just curious....have you checked your suspension sag...static and loaded?  Fork Preload CAN be changed by swapping  top of spring spacers in the forks....some use PVC, but  I've found the Chrome plated brass 12 inch long 1 1/4" Bathroom sink drain Tailpiece  pipe (at Lowes/Home Depot/Ace hardware etc...) to be almost an exact diameter to the original and you can cut it to size to give you the sag you need.

I'm 200 lbs w/o gear and the standard 10mm of preload was too soft....bottoming occasionally.... I ended up with 25 mm of preload and am happy with that/any more and I'd be going to a heavier front fork spring--also using the BMW 10w fork oil at the recommended volume for my type fork (Showa), which is 410cc drain/fill and 420cc diassembled......then turn your attention to the rear shock preload and adjust as well for sag.......

There's some helpful info here:    http://www.ibmwr.org/ktech/fork-oil.shtml

(not today, but yesterday)


Replaced the original rear shock with a RAM Shock.  That was fun, exciting and oh, so easy.  Removed the right fork, disassembled, removed and discarded the plastic spacer and original spring, cleaned everything, installed new RAM Gold Line progressive spring, put fork back on bike. Repeat for left fork. Have not progressed beyond this, because I ran out of daylight and had a hankering for a margarita.


It occurs to me that the forks need to be aligned. Square, plumb and true, so to speak.  I have the tops of the forks set at as close to the same height (relative to the top tree) as is humanly possible.  Visually, it appears to me that the tops of the lower tubes, all the mountings bosses, and the lower knuckle all line up from left to right. I test fit the axle without the wheel in place and when I slide it in from the right fork, the left end of the axle appears to be just about dead center on the opening of the left fork axle bore (thought it takes a tiny bit of persuasion from a rubber mallet to get the bigger right side of the axle in to the right fork...maybe I'll throw some moly grease on it so I'm not dry fitting when I reassemble). But what I was left pondering over (one too many) margaritas last night is, "Is there an easy way to ensure everything is lined up properly and not out of kilter?"

MI B, get a piece of glass from an old picture frame...make sure it's wide enough to lay flat against both fork tubes horizontally and that it fits just above the fork wiper to a few inches  under the bottom triple tree.  Insure that the fork tubes are equidistant in the top fork yoke, and that visually everything appears inline.   


Any discrepancies will show up when placing the glass flat against the front or back side of the tubes by the glass plate not fitting "flush' against both tubes.

Not proud of that today but thankful I'm sufficiently acrobatic to walk away with only rash....all armor installed for this ride daily...
It might be instructive to tell us the gear you were wearing on this occasion that enabled you to get off lightly.

Thanks to John Lang and gone_ape for the suggestions.  Today I filled each fork with 400 ml of Bel-Ray 10w, did the quick alignment method from that Delboy video and went for a spin. 63 miles at an average 44 mph, max 85 mph and all seems mostly well.


The rear shock is a little to much like a trampoline. I'll need to screw with the pre-load and rebound adjustments, I guess, to get it more in line with the forks.  On my bike, the Realm Gold Line progressives and 10w fork oil took the front end from cushy/wallowy/marshmallow to firm but not harsh, although on a sweeping, washboard lefthander I ride a lot, it got kind of...skippy.  Front end dive under moderate braking is gone (though it will still dive a bit on emergency braking).  The new fork seals are not leaking either, which makes me happy happy.

Firstly, i was just plain lucky...off 20 feet sooner and I would have collided with a culvert...end of story..im still kinda numbplussed I'm  not worse..

I Was wearing a GP sport armor clad jacket I just bought for my son off Craigslist. $60 well spent!!!.. Too big for him I adopted it thank the Lord..., my gloves have hard plastic knuckle guards I bought used off feebay, full face helmet didn't seem to take a hit other than popping the face shield loose on one side... Gander jeans were shreaded, back pocket on side nearly worn off. Cross training running shoes pinky toe bruised but no pain.  Stupid choice.   My only rash was below the waist ...both knees have baseball size rash.  My glutes and lower back are severely bruised black...interestingly my knock off GoPro mounted to my chin was un touched and recorded my tumble. My Trump card though is a lifetime of trampolining, skiing, gymnastics and of late- karate that driil into ones head to tuck and roll. My hand would otherwise have shattered. 

Armored pants are a must for me in future. I'll post the video someday...

The bike is disassembled tonight...lots more damage than I originally estimated. All but one fiberon fairing component are damaged.  I may have to walk away from it.  A cause for mourning. There's a nice 91 on eBay for what I'll get from the insurance.  Gnight. Pics of shreaded elbow armor tomorrow.  Thanks fir asking Laitch- therapeudic...

I'll buy the bike from you for $600.  Judging from your photos the fairing damage can all be repaired in a week for under $200 bucks in materials.  With clearcoat done at a pro shop the bike will look better than before the crash.  All that you need to buy is the turn lens and a windshield. 

tragkorbs look like the hinges let go.  About $12 for hinges. 

As I mentioned earlier, these K bike fairings are very repairable.  I wouldn't walk away.

I was trying to get some "O" ring and filter service kits locally and wasn't having much luck. Supercheap put me onto an injector specialist in Brendale.  On the way there I thought I'd check out a place I'd used previously many years ago also in Brendale. The place was still going and specialized in fuel injection and European cars. New owner since 2004 was great, I told him what I wanted and he fronted with a big kit. He supplied me with the "O" rings, spacers, filters and a three sets of different pintle caps for $15.00 Au. He then asks how I was going to clean them, I said with an ultra sonic cleaner. He came back with Aldi and I said yes, apparently I'm not the only one to come up with using their jewelry cleaner to do this. He asked what sort of cleaner I was using and I said injector cleaner which I buy when it's on special, normally it's about $15.00 Au. He told me not to waste my money just use paint thinners a hell of a lot cheaper.  So I'll give him a plug Mick at BMTS Brendale (07) 3205 7711. There are still good guys out there.

I put new roundels on the petrol tank, one is the correct part, the other is a car part, can't really tell much difference.
I also added some molyD to the gearbox, shifting could always be better.
I know, "lube the splines." Don't know when this was last done. Only 33K on the odometer, and I've only put 1000 of those miles on it. Videos on the Splintology post never stop loading.
I also used some vinyl repair goo on a couple of small spots on my seat. Seems to be difficult to find a decent replacement without spending the bank. I might consider a new cover with a bit of extra padding.

Blitz see these sites for seat recover. When I did my JO seat I ended up having to buy a $40.00 air staple gun and paid $20.00 for a piece of left over stretchable vinyl from an Upholstery shop. I did chicken out and get a mate to do the cover but having now seen it done, I would do it next time. The You Tube Video is actually on a K seat. And I have used the staple gun a couple of times now once to staple a cupboard back on and another time to replace straps on a lounge. I thought I would never use it again.

Thanks Martin,
I've seen covers for about $40. It looks as if they attach with rivets.
I have recovered a couple of Triumph seats in past. A space heater helps to stretch the vinyl. The seat I have is a Corbin, but looks to be the same contour as a stock seat.

Originally they were attached with rivets, however most upholsterers now use air staple guns. I've kept the plastic strips that were on them originally that were used with the rivets. There used to be heaps of aftermarket covers on Ebay but they have disappeared except for the ones in the US and the UK.

Installed a new fuel sender unit, but first I carefully measured where the old float rested on my work table.  Then, measured the distance of the new float and saw it was slightly lower than my old unit--and stopped below the table top.  I then turned the gear wheel CCW one tooth, so the fuel sender unit would not come on so quickly.  (Owners Manual says the low fuel light comes on at 1.3 gallons.  That is too early for me.)  Full tank of fuel to run out to see what mileage when fuel light illuminates.  I know how many miles I can go before going into fear mode of running out of gas.  The reminder light is fine--as long as it gives me an accurate reading.

Replaced my Hall Effect Sensor.

First got symptoms when caught in stop-and-go traffic, stoplights, etc. on a warm day: First a rough idle, progressing to random combinations of refusing to idle (without throttle or "choke"), stalling, no acceleration, and refusing to restart until cooled off.

The engine angels really helped me out by (1) not letting this problem start on any of my long rides this summer, and (2) alerting me to it before I left on my annual ride to Vermont. The timing meant I had to drive to Vermont in a rented cage, but that sure beat getting stranded on the Merritt Parkway.

The Euromotoelectrics replacement is a great buy and a perfect fit, I highly recommend it:

http://www.euromotoelectrics.com/product-p/boignsen-k033edl.htm

PS: Just noticed that EME also sells the gasket for the T-shaped piece that covers the HES:

http://www.euromotoelectrics.com/product-p/tc-gasket307.htm

If you buy their HES, order this gasket too, because the one on your bike will be shriveled up and useless. (I used some gasket in a tube, which actually cost more than this gasket, which I didn't take time to look for.)

Rode to work today. Only ten miles on the parkway. Either the molyD did the trick or I'm learning how to shift this thing, no problems.
I do need to take out the GPS and ride just to see where my speedo is. Low-profile tires and it reads 80mph at 5000rpm in fifth.
This bike reminds me a lot of my old Triumph Trident. Doesn't handle nearly as well, though.

Good to hear it's running and shifting well now. 

80 mph at 5 grand sounds about right.  If I remember correctly, top speed at redline is about 154 mph

Go to Anton's gearing page and select the correct final drive ratio used on your K-bike.  It will produce a graph. Click on the "5000 RPM" link in the accompanying text to get a grid overlay showing the projected speed for different gears at 5000 RPM.  For example, if you had a 33/11 ratio FD, 5000 RPM in 5th with standard tires will give you 75MPH. You have low profile tires and possibly a different FD so 80MPH might be correct for your combination of driveline components.  A more accurate means to validate speeds would be to you to download and install K-diag.

Took the bike out for a lovely ride down the Natchez Trace, a nice limited-access two lane. Speed limit is only 50mph, didn't touch the brakes all day. Circled back through Columbia and up the interstate. About 200 miles, round trip.
Checked the speedo by timing myself between mile markers. 90 indicated times out to about 82mph.
Ended up at a bar throwing darts. Kinda strange switching to Coke after a couple of brews. But, good thinking. A cop followed me for a couple of miles after I left. No blue lights is a good thing!

I enjoy a bit of inebriation but too much is not very much,for me. :falldown:
Last time,years ago,I had the red n blues following me for about a mile I got done for not having a rear view mirror.The chase had two cars involved and when I did the life saver look over my shoulder,I  spotted it and slowed down to let it pass.It didn't pass.Then the other one screamed up from the other end of the road.I was on the Guzz so being loud couldn't hear too well and it also goes like you just stole it which was why they were actually interested in it and me.Very nice of them to be concerned for my property!
