Question Major tear down with lots to do and questions I'm sure...

Well I finally finished all but one of my licensing board exams and found a signed a 124 page residency contract this morning so I finally have time to tear into the bike. I was looking for an area with great motorcycle roads and skiing nearby as well. I matched with a program in southeast West Virginia so I think I nailed it.

First question. My fuel gauge didn't work after I repaired a torched wiring harness. There was voltage there but no signal up top. I took it apart tonight and the float moves freely up and down. I then checked the ohms and set at 200K I get 1.1 and it doesn't change when I move the float.

I further took the unit apart and notice that there used to be two very fine wires that resemble light weight fishing line or fiber optic cable or hair for that matter that ran from top to bottom through the unit. The float slides up and down on a shaft and the along both wires thus changing the resistance depending on where it is. I'm going to try and fix it using copper wires because I don't know where I would find wire like this.

Any idea if this will work. My guess is that it won't because the resistance won't be right with the wire change.

More to come I'm sure.

Thank you in advance!

Re: Major tear down with lots to do and questions I'm sure...

After pics

Resistance seems to be around 10 ohms when empty and 5 when full.

Now to hook it up...

Re: Major tear down with lots to do and questions I'm sure...

Well evidently the silver wire has a lot more resistance than the copper because the copper is measuring .04 full and .07 .08 empty or extended.... The gauge is registering full just fine but empty, it only deflects down to 8 or 9 10ths of a tank. If anyone knows what this wire is and where to get it, let me know...

Congrats on the life change! EBay was probably the right choice. The resistance element doesn't sound like the typical radio shack item. Probably ni-chrome or some other specialty wire.

That's what I was thinking but it was worth a shot and a nice little late night diversion.

Re: Major tear down with lots to do and questions I'm sure...

The wire is most likely NiChrome. Not easy to find in small quantities, and the size has to be right. McMaster has small sizes in 1/8 pound spools, but cost just about as much as you found a used unit for.

Re: Major tear down with lots to do and questions I'm sure...

Got the speedo back in and installed the higher watt low beam HID and the 55W High beam as well....

I'm not sure if anyone has ever written anything on the high beam install, but it doesn't fit. I had to splice the wire to get it through the goofy mount... and then it was too long so I glued it in LOL.....

Start of my fuel filter re-route.
Special submersible ss covered fuel line and my favorite hose clamps. Gators by Comp Cams. I have enough of the special fuel line for two more bikes if anyone wants to do this let me know. I'm using regular ss covered line outside.

Re: Major tear down with lots to do and questions I'm sure...

Finished my fuel filter re-route (pics included) today and also installed the peg lowering kit I bought over a year ago LOL For what they charge for two chunks of aluminum you would think you wouldn't have to hammer the pins in.....

I after I do the oil, the final drive and the brake fluid etc. I want to put as much of the bike back together and still have access to the fuel sending unit which means I need that side panel and the stingray off I believe.

Can I put everything back on but those two parts? I forget.

Nice post. Good pics. I assume you did the fuel line mod to have access to an external fuel filter. Do you leave the original filter in place? Can you describe/identify the ss tubing you are using?

Also, how did your bike get "torched" (in reference to the wiring harness...)? ie, is there something we need to look out for on our LT's?

Hope you get the WV posting, sounds like motorcycle riding heaven, close to Blue Ridge Mts, Smokey Mts, etc!

I did the HID upgrade (high and low) just after I purchased two years ago...high beam was a beeatch, as you stated...had to drill out the hole where the bulb goes in, then had to secure the bulb holder somehow (don't remeber exactly what I did)...has not moved in over 16,000 miles since I did it.

I also did the brake fluid flush this year, it was a slight pita, but once I got the "hang of it" it goes quickly.. I used the opportunity to replace pads and install speedbleeders, I think one of your recent posts showed you purchased them as well. The speedbleeder waste bag and hose was indispensible. In fact, if you place the bag "upstream" (that is, higher) from the bleeder you don't really even need the speed bleeders. I still like them. Makes me feel good! What a huge difference the new fluid made in the brake "feel"-brakes seem to engage immediately, and the feedback to the lever is great! Also changed the clutch fluid and lubed the shift linkages...AWESOME! Shifting seems less clunky.

Lastly, what does your screen name (atrovarious) mean?
Oh, and the youtube link (what i am thinking right now) is not working.

The LT will run without those 2 parts. And I believe the turn flasher bulbs also operate, although they aren't very visible if you'll be cruising down the street.

Re: Major tear down with lots to do and questions I'm sure...

Thank you. Here are your answers.

I assume you did the fuel line mod to have access to an external fuel filter.

Yes

Do you leave the original filter in place?

No, I bypassed it with a submersible line inside the tank.

Can you describe/identify the ss tubing you are using?

Spectre 29310 - SSteel-Flex; Fuel Line; 5/16 in. ID; L-10 ft.; 1 US$24.95

Spectre 5964 - Canister Fuel Filter; 5/16 in. Fuel Line; Chrome Plated Steel Housing; 2 US$6.62

Aeroquip FCA0603 - AQP Racing Hose; 3ft. Hose; -06AN Dash; 0.34in. I.D.; 0.55in. O.D.; 1000/750 PSI; 2.5in. Min. Bend Radius; 0.16 lbs. Per Foot; 21in. Per HG; 1 US$16.95
(SUBMERSIBLE LINE)


Also, how did your bike get "torched" (in reference to the wiring harness...)? ie, is there something we need to look out for on our LT's?


In my case, the HID system overheated the headlight power wire (not fused) back at the bike main computer in the main wiring harness. As a result the entire harness was damaged resulting in further shorts and damage away from the main harness. It took me about 20 hours or so to fix and 10 buck in parts....


Hope you get the WV posting, sounds like motorcycle riding heaven, close to Blue Ridge Mts, Smokey Mts, etc!

It's a done deal! Just signed the 125 page contract.

I also did the brake fluid flush this year, it was a slight pita, but once I got the "hang of it" it goes quickly.. I used the opportunity to replace pads and install speedbleeders, I think one of your recent posts showed you purchased them as well. The speedbleeder waste bag and hose was indispensable. In fact, if you place the bag "upstream" (that is, higher) from the bleeder you don't really even need the speed bleeders. I still like them. Makes me feel good! What a huge difference the new fluid made in the brake "feel"-brakes seem to engage immediately, and the feedback to the lever is great! Also changed the clutch fluid and lubed the shift linkages...AWESOME! Shifting seems less clunky.

I'm certain that when the shop put in my new transmission and clutch they put in new clutch fluid and lubed if not replaced the linkage....SURELY THEY DID?!?!


Lastly, what does your screen name (atrovarious) mean?

Just a word I made up a while back.atrovarious: adj. To possess a variety of talents.

Not to ride... I just want to know if I can put the most everything back on and leave the stingray and right side panel off or if I need to leave anything else off to have access and not have to remove something to put the stingray back on.

However my part that I ordered late Friday night came today

I also picked up some Royal Purple 15-40 for the engine and 75/140 for the rear drive along with some Wix filters. As I said the gear box has new BMW oil in it with the new transmission and clutch.
