Tom in Virginia

My bike's in same situation, she's tired of takedown/reassembly and wants some ride time. Now, coils due Tuesday from MGG Cycle so tanks coming off off again. Still gonna be there, just may have to bring a backup ride so I'm not left watching

I cleared the 2 faults indicated. Last night I changed out TPS with a new one and set it as close to157mV as possible. I'll inform after completing another decent tuneup process. (note the black line that shows gaps as I throttle upwards and back down. Appears that is where the bike is stumbling and popping/surging. Hope new tuneup process resolves these holes)

Yup, kinda hijacking this thread but here it is anyway....checking TPS now to see if its smooth transition up/down. Seems to be but I may change TPS to a new one anyway. Also CO Fuel Trim. GD shows "0" on the +/_ screen with START button but then click START and GD gives me what I'd call an error screen that says "Active diagnostics could not be started". Tried multiple ways to get by this running, ignition on, off running, motor cold/hot and hot >60C.. No help.

OK, kinda dumb lazy question here, should my 2003 LM have an O2 sensor installed? I just yesterday removed the PCIII, replugged the ECU wiring back into the 15M ECU. Going to "try" to run the GuzziDiag and see if I can work thru/get system at least up/running to check a few parameters. Not going to make any changes though. Bike ran very well 4k to redline. Coughs, spits, stutters surges below 4K when off throttle or transitioning up/down. Idles fine. (Valves in spec, TB s balanced, air bleed screws cleaned, new plugs, new NGK plug wires, new OMRON relays (all 5), fuel filter and pump appear ok, clean K&N air filter properly oiled, intake box cleaned of smudge, intake boots appear OK)

Wikipedia: "The report's conclusion was that the probable cause of the accident was explosion of flammable fuel vapors in the center fuel tank. Although it could not be determined with certainty, the likely ignition source was a short circuit.[1]:xvi Problems with the aircraft's wiring were found, including evidence of arcing in the Fuel Quantity Indication System (FQIS) wiring that enters the tank. The FQIS on Flight 800 is known to have been malfunctioning; the captain remarked on what he called "crazy" readings from the system approximately two minutes and thirty seconds before the aircraft exploded. As a result of the investigation, new requirements were developed for aircraft to prevent future fuel tank explosions.[9]" Lesson learned: If your fuel gauge starts giving you crazy readings, BAIL OUT!!!

That's the same center but somewhere there is one that includes the falcon in the black background. As you said,

Wait now, you are speaking of a Kentucky garage, right? Makes sense though, they were essentially purging the tank with carbon monoxide and various other gases.

https://www.mgcycle.com/index.php?main_page=product_info&cPath=30&products_id=5389 The MG Cycle fuel pump is supplied with a pigtail, but if the old wiring/connector is in good shape and the fuel pump connector is compatible then I may not have to make any "connections" other than plug and play. That avoids incurring any wiring challenges. Another concern was having to mess with the wiring penetration at the base of the fuel pump foundation where all 4 wires penetrate the rubber tank grommet and exit the tank to the external plug in connectors. The fuel pump is not all that expensive so that'll be in hand, as well as the hose clamps and crimping tool, and added to my winter tear down work list when I take the tank off again. Yes, I guess once the tank is closed, then there may be gas fumes in the void above the liquid fuel but not per se "oxygen". I certainly hope so Phil, the "pig tail" in the MG Cycle link kinda made me think I need to do something more than just plug in.

Anyone have any idea who might stock the tank decal identified in picture. Once the tank bag was removed, noted that the decal underneath has several large bubbles. Not a big deal, if I can't source one then will just leave as is. Internet searches have been fruitless. Thanks in advance.

Can someone explain how an in-tank fuel pump with 6 different electrical wires/connections (see picture of pump) can be immersed in a tank filled with gasoline not cause the tank to explode or cause any kind of fire? I took my tank off and pulled the fuel pump unit. Plan was to replace the fuel filter but it back flowed onto a clean cloth with very little to no sediment and the filter is a metal one so assume it has been replaced at least once prior. Also did not have the proper hose clamps and crimper to reattach the filter to the hose. While I was in there planned to replace fuel pump as routine maintenance. Admittedly I am reluctant since I would have to cut wires and remake connections. With concerns for how to properly electrically connect wiring inside of a tank that holds highly flammable liquid, I decided it best just to reassemble the pump unit into the tank and put off until I have more knowledge on the subject/maintenance. Thus the lead in question. The metal foil tape covering the heat resistant cloth on the underside of the tank was showing its age and a bit knackered so I recovered it to give it some more life. Thanks in advance for the knowledge and suggestions.

Great pics Bill, looks like a really fun time. Sure the stories were a lot of laughs.

Wow, Matris has gotta be making a killing on a $400-$500 steering damper!

I like...

Anyone have any experience with this rear shock on an '03LM? I have the fork spring kit installed in front forks from what PO paperwork tells me. The rear shock remains stock and have had no problems with it, pretty satisfied overall but its getting up in age and may consider an affordable replacement. https://www.webshop-hyperpro.com/en/motorbike/moto-guzzi/v11-le-mans/v11-le-mans/2002-2005/suspension/rear-suspension/rear-shock/MG11-0AA

Tell us more! So my son sent me the DNA, kit, sent it in. Pretty cool but somewhat as I expected: 62% British Irish 32% (but specifically recognized Isle of Mann area!) 4% Swedish and surprisingly 1% Filipino and 1% American Indian.

By quick comparison between a '02 and '03 tank ring, measurements appear to be the same. However, I only measured with carpenters rule, did not micrometer. Note that the 2 most forward screws are inverted flat head machine screws installed from the bottom of the lower adapter ring and do not match the tank ring cap screw locations below them. This is how SWMotech adapts the upper lock ring on multiple different tank ring/bike configurations. So to answer the question, it appears the tank ring bolt config is the same between early and later models (at least between an '02 w/chin pad and '03 w/o chin pad).

It's past time to review all the tracks and make MotoGP races safer, as reflected by the 2 horrifying crashes last week. Unbelievable no one was killed in either incident. You will have to follow the links in order to view it on YouTube. (Admin: remove this post if it is unacceptable). Thanks, Tom

Note sure what you are speaking of as to chin pad bolt pattern. The chin pad sits forward of the tank ring. The 175 should work no problem. The challenge will be getting the bag to lock in to the ring as the chin pad "padding" will interfere on the 2002. As I noted above, probably the cleanest way to mount the tank ring/tank bag without having to take the chin pad off of a 2002 tank is purchase multiple mounting rings (Pc. 2, Part #TRT.00.640.014). If you can obtain the individual mounting rings (which really just a spacer ring) from SWMotech you can stack 2 or 3 mounting rings underneath the top latching ring." Or if you are so inclined you could fabricate a couple of rings out of hard plastic or aluminum using the Pc. 2 of the kit. Someone with a 3D printer or a CNC machine could undertake this no problem. You would need to adapt longer bolts than those supplied with the kit but it would then allow you to clear the chin pad thickness. With the 03 LeMans (w/ no chin pad) my large 15-21 Liter SWMotech bag has to be pushed down very slightly to lock in. Not the case when installed on the Norge as the tank ring sits very slightly higher.

OKay, sorry I wasn't quicker to find it and respond. Could have saved you a few clams.

I feel ya! 14 misc surgeries, need another 3 to get both my hands right and 2 more on my knees. Can't pick a box of milk outta the fridge but I CAN still twist the throttle!

Rode it from Idaho to Virginia in May 1980. 2200 miles in 3 days. Back then I was pretty tough. Now at 63, if I do 400 miles in a day then I'm done for a few days. Wouldn't trade my memories on this bike for anything.

2016 Norge, love it!

The line is long. I told my son's they could decide between them who gets it when I'm gone.
