I'm still on all my 25 year old cables. I have fitted a grease nipple to the clutch arm. And every second or third oil change I lube all the cables with a PTFE lubricant called Triflo. Do not lubricate your cables with WD40 or it's like as this can accelerate the break down of the liner. Triflo can be bought from bicycle shops. It is also important to check that your levers are not catching on the cable causing it to fret.

I'm now learning that you should lube the pieces that hold the ends since they pivot in the lever and arm respectively. That's probably what did me in.

I forgot to say lube the ends. Lube is cheap compared to replacing parts.

Clutch cable snapped at the handle the other day. Got home and ordered a new cable, only to realize when it got here that there's a stupid brass bushing/holder that sits in the lever in such a way that when the cable breaks, it just falls out onto the road!!

(Could they really have not put a little lip or it so that it wouldn't just fall out? Geez...)
I’m lucky I saved my old throttle cable when I ordered a new one. It has the adjuster trapped inside a rubber boot that you might not think to remove before you pitch the old cable. You’d think not having these fittings on the replacement cables would make them cheaper. Yeah right.

New clutch cable installed on lunch break on Friday made for a nice Saturday of riding out at the Gap.

I went with a Venhill replacement cable. Couple observations: The accordion boot on the clutch arm end is smaller, and slips right through the cutout on the trans. That's nice.

The Venhill cable that supposedly fits 1985 K100RSes is ever so slightly shorter than the OEM cable. It works just fine, but you have to readjust some of the routing. Once you do that, it adjusts and works as normal.

Anyhow, here's a couple snaps from the weekend.





Next month, Dad and I are setting off on a decent little trip. I'll be on the K, he'll be on his 2100 Vulcan. Guess I should mount my top case before then.

Thanks. There's still a lot of potential in the bike I haven't tapped yet...still a little worried about dropping it again. It really does handle well for what it is. I've outrun a couple late-model 600s on some local roads, but I'll need another month or three to learn the bike before I'm really comfortable pushing it.


I need to put my fork brace back on as well, and maybe look at an improved rear shock.

Well, I shoved this bike back in the corner of the shop where I couldn't see the damage. After having it sit up a couple months, I got a wild hair the other day and decided to start fixing it.


I sourced all the bodywork I needed awhile back, so I disassembled the bike and took the parts that needed repair to the paint shop. Should be somewhere in the $400 ballpark to fix and paint those. Not too bad.


I also have a blown fork seal, so I ordered some replacements up. I'll deal with that here soon.


The exhaust is scratched, but you can't see it with bags on. I think I'll just hit it with some silver hi-temp paint and forget about it.


I did manage to find a NOS left Series III tragkorb, so that'll go on nicely. I'll also use this opportunity to recover the seat.


The rear master always leaked, so I did order a replacement. I'll be converting to the ebay universal master cylinder.


Anyhow, if I can find some time, It'll be back on the road within a month.


My porch ornament came with an extra exhaust; if it's in good unscratched condition, it's yours for shipping.  It would look better on your bike, anyway.

Nailhead/propav8r, if either of you wind up with an exhaust you don't need, in scratched or unscratched condition, I'd be happy to take it off your hands and give it a good home.  Brunhilda came with a Supertrapp that I'm not too fond of and I'd like to try a stock exhaust...


Thanks!

Jim,
Want to sell your supertrapp? What don’t you like about it?

I’m looking for a Remus or Supertrapp to replace my Luftmeister.

It's a bit loud, but that's not a big issue.  It's short and dumps the exhaust on the back tire and on the left bag.  Not really interested in selling unless I can find a cheap stock exhaust to replace it first.  It's my daily ride...

I totally understand that. Keep me in mind if you find a replacement. I’see cheap stock exhausts on eBay pretty regularly.

Cable guy, I have a dinged up K100 exhaust that you can have for postage.  It's off of Moby Brick which was the victim of vehicular assault by a KIA last Fall.  It will probably need a bit of work to get it to fit, but it is intact.  I don't need it, and really don't want to take anyone's money for it.

Took the bike on a little break-in trip this past weekend, down to Montgomery AL and back home. All in, it was just barely shy of 800 miles. The bike performed perfectly, and I had great weather the whole way.

Started out at about 5am, hit the Tennessee Valley Railroad Museum in Chattanooga at 9am, Barber Vintage Motorsports Museum at 1pm, and I was in Montgomery for dinner.

















I have hundreds more pictures, but I digress. If you've never been to the museum at Barber, you need to put it on your list. It's amazing.

On the way back I rode through the Talladega National Forest which forms the southern terminus of the Appalachian mountain range. I think I found one of a handful of relatively curvy Alabama roads.



Maybe all this is better put in a trip report...oh well.

Anyhow, I do have a couple of questions before I head out on a longer trip here in about two weeks. When I got home, I washed the grime off the bike before I unpacked. One of my Gen 3 cases has a water leak. Not terrible, but I also don't want my clothes getting wet if we hit a rainstorm. Can I get new gaskets for the cases or should I just bundle everything in garbage bags before I pack it?

Also, I have a Metzler Lazertec on the back now. I'm not sure how long it's going to last, and I might wind up needing a tire mid-trip. Is there any reason a 140/80-17 wouldn't fit and work just fine? That seems to be a much more common in-stock size than 130/90-17.

I used to wrap my laundry in plastic bags, but now have tragkorb liners.  They work well to keep stuff dry and make it easy to unload the tragkorbs and carry your stuff indoors. 

There's lots of them on eBay.

I would lose the lezertec, I only 4 days and 2500 mile out of a new one just a week or so ago on a trip out west. Started out with 39psi (day 1) then tried 36 psi (day 2) then 42 psi (day 3) and replaced it day 4.


I also think a 140 (wide) would rub on swing arm.

Try either replacing the tragkorb seals or packing out the existing ones. There are alternatives to the OEM seals, and somebody in your neck of the woods will probably chime in.

Yeah, I was thinking about some foam rubber insulation I saw on a roll at the hardware store the other day. It was like piping, and I think sized just about right.

I'm making the final preparations for the trip. I did an oil change and brake pads last night, got my odometer fixed this past Saturday, and I'm getting a pair of tires tomorrow. I don't really NEED tires right now, but they're worn enough that I'd rather not have to hassle with getting them replaced on the road. Going a little budget with some Kenda Challengers, but given that I won't be carving turns on the trip (dad is a much more conservative rider than I, and I don't want to dust him), they should do just fine, especially at $140 for a set.


I tried a few things and wasn't able to stop my top box and right tragkorb from leaking, so I just popped a couple drain holes in the bottom of the top box, and I'll pack my clothes in the left case and the camping gear in the right. Neither leak very bad, but it's enough to leave a small puddle in the bottom.


Anyway, I've also been dealing with a strange issue where one of my front wheel bearings loosens up in the bore of the wheel. It walks in the bore and on the shaft, and makes a disconcerting noise. The first time it happened, I removed the bearing, lightly peened the bore, and put the bearing back in. That held for a few weeks, but eventually loosened again during a trip to the Gap.


I disassembled it again, peened it much more thoroughly, and used Loctite bearing retainer to sorta glue the bearing in the bore. Obviously, the long-term fix is to source another wheel, but I didn't have time for that at the moment.


Anyhow, sans tires and packing I'm good to go. Should be about 2000 miles all in on the trip. I'm really looking forward to it.

With the bearing walking there is a Loctite product specifically made to counter this. I don't have the specific product number offhand but it should easy to locate.

There is more than one Loctite product that can be used. There are ones for small clearances and ones for larger clearances. Go to the Loctite web site it might help without having to replace your wheel.

I've had good luck with locktite "sleeve retainer" (green, got it a long time ago and have not seen it lately) and just the regular stuff as well. As for the kenda's watch out for wet roads!


Good luck and I hope you have a safe and fun trip with your pa.

To keep the stuff packed in my cases dry, I use dry bags left over from my sea kayaking days. They come in all sizes, help keep your stuff organized and when you stop for the night you need only bring in what you need.
