Does anyone know anything about the late seventies Yamaha XS1100s?

The father-in-law is apparently trying to one up me now that I've got my KZ650 in order and is looking to replace his Goldwing with a 1978 XS1100. The specs look good but I'm not sure on reliability, handling, etc.

That's a move down. The late 80's weren't Yamahas best days and the XS bikes had cooling problems. The inner cylinders tended to overheat, the 750's were worse but I have talked to a couple of riders who hated their XS1100's.

Arrgh. He bought it anyways. Looks like he's going to keep both. Its a low miles XS and is nearly perfect except for the tires. He got it for around $1000. I guess we'll see how it is when we tear into it.

Just be glad he didn't get a Virago, what with their infamous starter drives. I do seem to remember the 1100 XS's having some kind of transmission design flaw. The second gear always goes out or something like that.

I liked the Virago, and the starters can be fixed. They shouldn't have to be fixed, but that's the hand that Yammy dealt them.

Maybe I should clarify. I liked the pre-cruiser Virago, when I was more of a standard with a (for then) high-tech V twin. I've ridden a couple, they weren't bad for a bike of that vintage, and can be made into fabulous cafe bikes.

The second gear problem is practically endemic to Yamaha streetbikes. Google "undercut gears" for the fix.

Well the only saving grace is that aside from the occasional spirited takeoff he is pretty gentle with bikes, or at least he is with the wing. If there is overheating or gear issues hopefully he wont run into them.

Hes bringing it home tomorrow and then we get to tear into it. Coming right off the completion of my KZ650 I'm pretty happy to have another project bike in the fleet to keep the wrenches turning. Also as a side bonus the Yamaha dealer he bought it from is a new small dealer in the area and they seem like really nice guys. They're putting my tires on for $30 a pop as well.

Not enough clutch combined with no rev matching, mashing it into gear, not engaging it positively enough to get it to really mesh so it pops out. Stuff like that. Most of the time, it's idiots shifting by slamming on the lever rather than finessing the clutch, throttle, and lever to get it to go in smoothly. A little clunking is normal, the crash of gear on gear is not. Usually people who shift like that can be detected from the sidewalk.

It's also worth noting that second gear is the biggest jump gearwise, and on the kawasakis, there's a positive neutral finder that you have to shift through. So 2nd is particularly sensative to poor shifting technique. Plus people who are launching off the line will usually flog it flat into second with zero mechanical sympathy.

There are a handful of bikes over the years that have had really weak transmissions, and they've usually been revised within a year or 2. 2 bikes that I'm aware of legitimately potential transmission failure that's not the fault of the rider were the Kawasaki 93-94 (95?) ZX-6E had that problem and the 01-02? R6. Both of those bikes got revised transmissions within a model year or 2 with an additional dog on the transmission gears. T595 engined triumphs had glass transmissions for some engine #s as well, which was fixed by a revision later. The triumph could potentially frag any gear in that engine # range, usually on a normal shift.

Even so, I've seen plenty of early Es, R6s and T595s that were well cared for that have many, many miles on them and still have second gear. My zx6e, after me learning to clutchless shift on it, had toasted 3rd, 5th, and 6th, and wouldn't shift at over 13k RPM, but still had second.

When someone says their bike has a second gear issue after 5-15k, it's almost assured that they have no loving clue how to shift a motorcycle.

The problem is that you get people with limited experience or no desire to improve their shifting techniques flogging their bikes in the stoplight GP, or doing 2 gear burnouts. Normal shifting like you describe is fine. Clutchless shifting, done correctly is also fine. It's halfass shifting, or poor clutchless shifting that causes abuse. It's also a lot easier to learn to clutchless shift higher gears, as the difference in RPM from gear to gear is lower. First to second can be upwards of 6k+ RPM in change on an I4, and it requires a little more skill to pull cleanly than something like 4th to 5th, which is close to a 2-3k RPM change.

Hell, these days I even use the clutch on the track. The twin doesn't rev fast enough for me to really get comfortable with blips at high RPM on downshifts, so I use the clutch instead. Upshifts, I'll usually tap the clutch out of habit.

The gears on my 66' YDS are like butter and I can clutchless shift just by putting a little pressure on the lever and it will slide into the next gear when it wants to. The 77' KZ not so much so I stick to using the clutch.

The 75 CB200 that we use as a trainer...it's the sweetest shifting bike ever. Probably because it's crazy overbuilt. My track SV shifts pretty sweetly as well, probably due to the bearings in the shift arm. Seriously, if nothing else, upgrading to rearsets (or shift arms with bearings in them) is awesome for that.

What's all this I hear about new tires. Belt sander, scrubbing 'em, etc.


Go easy on them for 50-100 miles? I've just been taking it easy and doing S-turns and such when I'm in my neighborhood.

Back in the day they used to use some sort of greasy release agent when they made tires so something needed to be done to get it off. Hence sanding, burnouts, acetone, chants to the undergods.
These days there's no need but people still like to do it for some reason. I do what you do. Some slow S turns and a few moderate starts and stops and call it good.

The biggest thing is going from square old lovely tires to new round ones. I have almost steered my bike into the ground because I was used to wrenching the bars to get the drat thing to tip in.

Thank you for your email. We appreciate the opportunity to serve you.

Concerning your question, Michelin has a mold release agent on all
motorcycle tires
. This will cause the tire to be slippery in the first
few
miles, but that goes away after the tire is scrubbed in. This normally
occurs in the first 25-50 miles or so. Until then, the rider should use
caution in riding the tire at accelerated speeds. Michelin always
recommends
obeying the speed limits and using care whenever riding.

If your questions have not been answered to your satisfaction, please

Hello

Pirelli does not use mold release. Tires are shiny because the general buying public demands that visually a tire look cool, smooth, shiny, and new when they shop for tires in the rack at the dealer. We rely on the smoothness of the mold to get this appearance and to help the tire let go from the mold during production.

I like to say tires are like new shoes, MX boots, or a leather jacket as they need the proper break in time. Regarding getting heat into tires this follows the same idea, only time and friction will put the heat in. I have attached a copy of the brochure so you can read about break in suggestions in the technical area. Ride safe

Why would you rev the engine or attempt rev-matching while shifting up?

Sorry I wasn't clear. I meant rev as in turning the throttle normally until its time to shift up, nothing fancy. On downshifts I'll pull the clutch in, downshift, and blip the throttle before letting the clutch out.

Does anyone know of any good techniques for cleaning electrical contacts? I'm getting into the detail work on my KZ project and right now I'm just cleaning them with a small file and sandpaper. I feel like there should be a better way.

The bike has some old fashioned fuses that I'm planning on replacing with a modern ATC type fuse box, but this doesn't solve the problem of all the old bullet connectors.

Soap if fine. Whatever you do don't use any kind of lubricant that wont dry up.

A guy in our area died because a shop used some oil to put a tire on his Goldwing. He hit the brakes at high speed and the tire spun on the rim tearing the valve stem out. The tire deflated almost instantly, and he went down hard.

Wait...

That doesn't make any sense. I could see the tire rotating on the rim, which is bad, but how did it tear the valve stem out? The valve stem is usually mounted in the middle of the tire.

That's not to mention the loving :psypop: of a shop using OIL to mount a loving tire. :wtc:

Yes sorry, I should have mentioned that it was likely a tubed tire as it was an older Goldwing. I don't have a lot of details because this came from "old Tom" at our favorite bike shop.

The tube sticks pretty well to the inside of a hot tire so if it started rotating on the wheel it could easily tear away from the valve stem.

Seems like around 1k in fees is pretty standard. Depends on your area and the dealership.

On the tire biz...Yeah, ok...tubed tire, I could see it. But still, who the gently caress in their right mind thinks "oh no big deal, we'll just slap oil all over this tire!" It's...astounding.

It seems like the dealer markup varies location to location. I was looking at a 600RR a few weeks ago and they marked the drat thing up to over 11 grand with all of the fees. I think that's kind of silly. I can understand some doc fees but not much else. The prep is paid for by Honda same as the car dealer charges you for PDI when it's paid by the manufacturer. I guess they are just hoping someone walks in dumb as a post with pockets full of money (or at least a good credit rating).

Used, who knows. It depends on what the bike is and how rare and/or in demand it happens to be. They want to move it but they still want to make a profit.

Yeah, I looked at new bikes at two different dealerships. Both charged around $500-$700 for shipping and assembly, one dealer charged $200 for "administrative fees" and the other charged $350 for "documentation fee". Don't forget sales tax, which adds another $600 or so and a $9000 bike starts pushing $11000 easily.

I'm know a used bike won't have as many fees, but I'd like to know what's typical before I start haggling intelligently.

Honestly I have no idea. Old Tom thought they might have used WD40, thinking it was harmless, and sent the guy on his way. Maybe he took the bike out and crashed the same day while the WD40 was still really greasy.

There are some horrible shops around here with mechanics that are lovely even when they're sober. Likely the Goldwing guy went to the local "guy" in one of these shops and had the tire put on for a handshake and a tenner.
