What good are 'serious horns' without serious hooves?

Nemo, That would be like telling you once and for all that there is no Santa. You're probably better off to marvel at the roar when you push the button. I became afflicted rather early on. Instead of studying Algebra in eighth grade I thought it better to crawl under the dash of my brother's Austin Healey and attempt to make the little switch work that said "OVERDRIVE." Never did get that overdrive to kick in ( I don't think it really had one, just the switch) but have been chasing ( chased by?) little electrical challenges ever since. As the old Airframe and Powerplant (aircraft) mechanic once told me: " The hardest thing is to get the smoke back in the wires."

Wouldn't you have to use 'ceramic coat' ( like Jet Hot) to withstand the heat of the exhaust?

Well, for sure the clutch switch is out in the funk and benefits from a periodic clean, dielectric grease and seal. Just from the wirng diagram, it routes power from the start button to the starter relay to engage the starter solenoid. There are three points of concern in the run circuit : 1) The power to the ECU/FI relays goes through a single connector located under the relay stack. While it is a weather tight AMP connector, it does sit just above the rear fender and will benefit from a clean, inspect, dielectric grease. afterall, all the power to run must go through it. 2) When in neutral, the power to the run switch is through the middle (neutral) relay referred to as the " safety relay for stand " in the manual. It is not activated by the side stand but by the neutral switch. The neutral switch is prone to sticking ( always park in gear) but will not interupt running, just that the neutral indicator light will stick on. 3) When in gear the power to the run switch is through the side stand switch situated on the leading end of the side stand. This switch is really down in the muck! And all the power to the run switch goes through it. Periodically inspect ( along with the wires which run along side the alternator cover), clean with a spray contact cleaner and force in dielectric grease. If power to the run switch is impeded through the side stand switch , shift into neutral to see if normal running is restored as the 'neutral relay' provides an alternate route for power to the run switch . Keep the smoke in the wires!

Where from? KB,Cymru KB, Check out these threads: broken shift spring transmission springs

mik, Your LeMans is a Rosso Corsa or a Nero Corsa? ((My turn signals went on the fritz yesterday. Darned bike must have caught wind of this thread. Rampant animism! ))

Heck, I thought the clutch switch runs current to the starter relay. Such that, if it gets mucked up the bike won't start reliably. I didn't think it would affect the motor after it's already running? ? ?

Has anyone ctually measured what the bike draws just to run with its lamps on ?

Mik, Do you have a turn signal flasher mounted any where else? Does your 'extra relay' click and cllick with the turn signals on?

I'll have to wait until the tank is off to photo the relays. I mounted them along side the right of the spine. The stock horn wires reach them without modification. The 12V hot comes from the junction block after the stack of terminals began to eat into my psyche.

Er, is that "the horn button provides 12V to the relay ?" Keep the smoke in the wires , guys.

The power for the tail light also powers the instrument lights and the small 'city light' in the headlamp shell. Current flows through Fuse 6 ( 5 amp) and the ignition switch. Certainly a good idea to keep an eye on the fuse. The bulbs on the stock circuit are 11.4 watts so only pull less than an amp but the 70 watts of auxiliary light pull 5.8 amps. Just for the peace of mind of the ignition switch, a dedicated hot to the relay would be good medicine. Check out the junction blocks: Relay failures ( junction blocks) Great looking lights!

That original thread isRelay Failures. Here is a photo of the relays with the stick on letters. The turn signal flasher was relocated to this spot to make room for the junction block. There is nothing intuitive about the wiring to the relays. A careful review of the wiring diagram is vital to understand how the current flows. S - starter L - lights N - neutral ( side stand) C - ECU F - injectors/ pump/ coils

I would think there are many, many of us whose gearboxes will soon be apart where the springs will be easily accessible. This is coming at a perfect time to upgrade the reliability of the shift mechanism. Any word from the supplier on the nature and quality of the original springs relative to the aftermarket units?

There is room inside the clip-on above the stock weight insert for about an ounce (28 grams) of shot. Definately makes a difference along with Superbike grips and bar-end mirrors.

Ah! Chemicals, universities and experimenting . . .life at its best !

jason, I'm pretty impressed you've gone all the way back to November to catch up on posts! Says something about winter in Iowa. All the bird shot is in the # 6 - #9 range. The largest is 'BB' which are .177". Teh #3 an #4 is buckshot and the balls are about 1/4".

Thanks, Emry.

First problem on the Sport ( leaky front gearbox seal munted the clutch) came at 4000 miles / 6400 km. Your LeMans is ,as yet, young and virginal. John, with that beautiful cafe round-fin of yours can you say that the LeMans is that much more fun to ride? How so?

Yes, bummer, sounds like the return spring. I know we were all hoping this went away with the early '02. (Any news on our 'custom set'. T.P.?)

"72", Not unlikely that it will all just 'loosen up' with the miles. Does the the shift lever stay down as well?

Like many , I switched to the 160/60-17 on the Sport (from 170/60-17). Next tire I think I'll go to the 160/70 just to get a little more weight to the front. Sure interested in how many miles you guys are gettinr out of the Diablos. And , like the Pirelli Dragon, are there "corse" as well as other cmpounds of Diablo?

Er, what's "PDI?"

The rear Sport 1100 carb size: 160/70-17? or 160/60-17?? (I thought "michelin" was French for 'yer-arse -on the-street'.) docc (allergic to Pilot Roads)

Andy york in Nashville just fitted one to his LeMans. Send him a pm through the board and see what he says about it.
