What Did You Did To Your Motobrick Today ?

For $50 I'll stick with the wheelbarrow handle rig I am using now.  A little clumsy, but it gets the job done and doesn't hurt the wheel.

Action photo, please. Are you using the rocker panel of an SUV for a fulcrum?

Yippee Yi Yo! Rode the Beartooth Hwy (212) out of Red Lodge since the gates opened for this season. Such a nice day, scooted around Laurel and the Rim, back to Billings. Montana Life at it's best, tragkorbs are perfect for the grocery, chicken feed, Sharkbite's, and ammo run to Shipley-R's. No altitude plug needed.

Was there much traffic up there?

Motor coaches are just beginning to show up. Before the gate got opened, we rode bicycles to the plateau and bombed the return using the entire roadway. * Great Garmin pic

[The Mighty Gryphon]

Thanks!  I like the 70mph speed limit on 212 through the switchbacks coming down from the pass.  I bet they don't write too many speeding tickets there.

After many trials and tribulations, I discovered that the wiring in my fuel sender unit was faulty and causing a no-start issue. Pump works when given 12v, and I am getting 12v at the female end of the 4-pin connector.

There is no continuity between the yellow/white? lead to the fuel pump and the green wire on the male end of the 4-pin connector. The 4-pin itself is also (surprislingly) ok. All of this tells me that there is a fault in the wiring somewhere in the inside of the watertight sender connection.

Not being able or willing to dismantle this 90 degree, sealed, plastic fitting that goes from outside of the tank to inside (where I think the fault in the wiring is), I ordered a new sender unit. It's not cheap. Fingers crossed that it will be here in a few days.

Some of my good friends in Georgia and North Carolina planned a group camp to replace the cancelled British rally this weekend. I packed up the Beemer and headed out on Thursday. Beautiful weather, though a bit too warm for my good riding pants. Toodling along on highway 68, almost to Tellico Plains, when GRRR. I coasted to a stop beside the road. After checking the lug nuts I tried to get going again. It goes into gear, but when the clutch is let out it grinds and goes nowhere. I can only guess that the rear U-joint is toast.
After a few very hot minutes by the roadside another rider showed up. He rode to a motorcycle shop which I had just passed but they had no way to tow the bike, so he rode off to the nearest wrecker service.
Before he returned a sheriff's deputy showed up and let me sit in his air-conditioned cruiser. He was worried that I might be dehydrated, but I was coherent though sweaty.
After a while my savior returned with some guys with a trailer to load up the disabled bike and haul it down the road to the place he was camping.
Hunt's Lodge is a nice little motorcycle campground. I spent the night there in a cabin and met some nice riders from Florida. The owner of the campground is a very nice lady with two friendly dogs and a pet duck who likes to nibble on bare toes. I had always wanted to spend a weekend at that place, just not this weekend.
Today I rented a Uhaul to bring the bike home. It took four of us to get it up the ramp, and I spent way too much on some tiedowns at NAPA.
Home now, but it might be quite some time before I even bother to remove the rear wheel to inspect the damage.

[The Mighty Gryphon]

Have you been careful about phasing the u-joints?  Very important to prevent failure.

If it is the drive shaft, I have one here in good shape that I can let you have for $300+shipping. 

[BlitzenGruv]

I won't know exactly what's broken until I get the wheel off. Could be the final drive.
I had the drive off when I replaced the tire last year. I only greased the rear splines and whatever I could get to without further disassembly.
I'm not really clear on what is meant by phasing the u-joints. My only similar experience is with a large Ford van, which has two u-joints in its drive shaft. This whole assembly is balanced at the factory and must be reassembled according to the marks provided.
Now at home on the center stand in neutral, the rear wheel does not spin smoothly.

[BlitzenGruv]

Thank you for the explanation. I did not disassemble to that point when I changed the tire. I only removed the final drive and greased what I could get to inside the swing arm. Unless someone else has had the shaft out I assume that the joints are 'in phase.'
I suspect the final drive my be the problem.

So my parts finally came from Max's BMW. Thought it would be easy to change a few hoses and finally the fan would work. Nope, motorad strikes again.

Took all day and the fan still doesn't work on it's own. The tests show the relay getting power but the damn thing just doesn't work. When I ground it the light turns on AND the fan kicks. The temp sensor was bad and just replaced. I'm so frustrated I want to set it on fire!!!! UUUGGGHHHH!!!

Did you clean the threads of the stub pipe before you installed the sensor? Did you install it without thread tape?

[Idonthaveaclue]

I did clean the threads, they weren't too bad. Also when I check the temp sensor after warming the bike it's reading less resistance (480 Ohms).

Any other things I'm missing? I don't want to believe the computer is the culprit with only 31k miles on it.

Thanks Laitch!

Have you cleaned the pins and sockets of the Jetronic plug with DeoxIT—especially pin 10—and checked that when it's plugged in that the connection is firm? You'll want to do the cleaning with the battery ground strap disconnected from the transmission.

[Idonthaveaclue]

I cleaned the plug not the computer itself with automotive electric contact cleaner. Plug ten is which position?

The first thing I did was clean all the grounds, the one under the tank and transmission.

Cleaning the computer is not part of the picture. If you cleaned all the pins and sockets, then you cleaned pin 10. You need to be reviewing the troubleshooting guide. Download the link to the guide at the bottom of this post in Repair Guidance to do that.

I thought that was only no start, awesome. I'll take another look. When I did the idle test I let it sit for 10 min (its 100 degrees here), I wonder if it had an air bubble or that wasn't long enough......

The hi/low light switch is fried. Ï opened up the the left switch assembly and it looks pretty complicated and probably expensive to replace. All other things work, so Ï went down a few inches and cut the wires(just for lights) and connected just the low. It’s working. So Ï got a switch to wire in and mount somewhere. Input is either hi or low to output to the power for light. Gonna also power to the dash bright indicator. Someday i’ll probably replace the unit, but it does look to be a bit of work. Just needed to have a hi/low. Just don’t need any extra attention while, if ever, Ï do a bit of riding. Pulled the Supertrapp off and mounted original exhaust. It’s quite a bit heavier, but much quieter. Supertrapp mounts to its own single exit header, so now Ï can remount the big belly cowl. Might get a 4 to 1 someday to remount Supertrapp cone. I’ve probably knocked maybe 50 lbs off this thing over the years.

Describe what your fried switch looks like. Those switches are repairable by someone who is patient. Guidance to repair them is in threads on the Web.

yesterday i searched every craigslist nationwide to see if someone was trying to sell my stolen bike. Today i'm calling every pawn shop within 200 miles....

Yesterday I found out the bike has probably never had the gearbox removed at 59K (ouch)
Through spending hours removing the swing arm pivot plate
After banging away at it with the slide hammer, the only way it would budge was with a pipe wrench to turn it
The plate now looks like an ABS brake disc ring!

Let the battle commence to work around the ABS to get the gearbox off!
