Guzzi Le Mans 2 questions

The bike has been laid up for three years and I'm about to fire her up again.

I have a couple of questions to the learned:

Although this has been in dry storage, I have read that a shot of oil in each cylinder and hand crank to lube the bores/rings before starting is recommended?

And I can't remember which way the battery goes in. Seems to fit only one way (longitudinally with terminals to front and rear) but I don't know whether +ve is to front or rear..

Thanks

I can't remember which way my battery goes in, but yes, it definitely goes in longitudinally. I think neg in front, but it really doesn't matter. Just put it in so that the cables reach the best.

I little squirt of oil in each spark plug hole is a good idea, and be glad your Guzzi doesn't have chrome bores like the earlier ones do.

Keep your fingers crossed!

Nice bike. Follow the battery leads, the one that connects to the frame somewhere(probably below the battery tray) is the -ve earth.

it is easy to check in which way the batterie goes in, just take a look at the
cables.
one side has a thick large cable, aka ground, that should be minus then.

the other side has a thick red cable to it, that is plus as it goes to the starter
solenoid.


what I would do prior to start: get the sparkplugs out, spray is some little oil,
and have the starter turn the engine then 'til the oil pressure light turns off.
get the sparks back in, start the bike.

if you want to be more cautious, you could get the rockers covers off and
have some oil put down the pushroads so they lube the camshaft a little
prior to turning the engine. Not sure though, if this is necessary after
a three year stand still. I'd say yes.


all the best with the bike, I had one of these, buddy has one, they are great.

Thanks all. Negative strap to front once I pulled the side panels so I could see something.

Squirted some light oil in both bores and span it once on the starter with the plugs out, repeated then plugs in and she fired up first touch. Sounds sweet.

Those Lafranconis sound like nothing else


Got another question for the wise. All the electrics seem OK (indicators, brake lights, and idiot lights apart from the headlight. No dip, main or any dip or main indicator lights on the panel?

Fuse? Unplug any connector blocks around the headlamp area and make sure connectors are clean. Give them a wiggle to see if any lights give a flicker.

This was a Mk2 converted to a Mock 1. The guy that did it fitted replacement clocks, headlamp bars etc. I'm assuming he rewired/replaced the switchgear too.

It's been in storage for three years. I've only just got round to getting it on the road.

I assume the off / on rocker on the right hand bar is for the lights?

Looked at the fuses, all seem OK. Pulled the nose fairing and tried waggling the headlight around but nothing. I'm OK with engines but novice status with electrics. Looks like I'm about to learn

I assume I start by testing that juice is getting to the headlamp?

if 1 + 1 equals 2 where you are at, it sounds like a good idea.

Sorted.

Some odd wiring on this bike. The engine kill switch is wired backwards (off is on) and so is the light rocker. The light problem was the fuse block, some corrosion in the fuse bayonets.

Looks like I am about to get inducted in the mysteries of Guzzi wiring. I think this bike could do with a new loom and the electrical system bringing up to date.

you are starting at the deep end , troubleshooting electrics has its own learning curve , this bike has been modified , so you've got the previous owners work added to complicate things.
personally i would convert it back to original , but i am one of the few fans of the original styling....

Another stupid question:

Tires:

The bike has the original LM2 alloy wheels and is fitted with 100/90/H18 front and 120/90/H18 rear Avon Roadrunners, probably tubed.

From reading a few posts on Wildguzzi I think these alloys were meant for tubed tires and Avon Roadrunners or Bridgestone BT45's same size fitted with tubes are OK?

Any of you run tubeless on these alloys?

hi there.

Bridgestone BT45 are the best tires I had on an 18" rim so far,
but I haven't tried any Avon yet.
those rims can be used tubeless I guess, it should be a matter
of a correct valve and not much else I believe, since these are
no spoke wheels.
there is a Le Mans III discussed on the Wild Guzzi board currently
of which has got a tubeless "conversion" to it.

I would skip that "new wiring loom" idea for not to get into too
much trouble but to ride that thing at first.
A good wiring loom is a lot of work and needs some brain stor-
ming at first if you haven't got too much experience with that
kind of work yet.

cheers.

Cheers Rumba. I'll ride it until something breaks

What a bike this is. Way better than I imagined. I wrote his earlier today on FB:

'This was a big day for me. I bought this bike 3 years ago to scratch a 30+ year itch. It's travelled farther in the back of a van than I have ridden it in that time, due to my working overseas.

Today I took it to the test centre to get the MOT certificate. The sound of those Lafranconis on full song is incredible. People nearby called for the priest. Some called for two priests, just to be on the safe side. Cows gave birth to stillborn donkeys. The sky parted and Will Smith descended on a sunbeam surrounded by a squadron of black swans. The moon exploded.

It failed the test. Perished tires. Back on Thursday.

I've never ridden a bike as visceral as this. It's like a jockeys position, which kills the hips but I'll take asprin before the next ride. The thing sways and shakes at idle like an angry bull. Open the throttle and it takes off like a stampeding hippo, singing baritone and setting off car alarms as it goes'



I can see why guys love Guzzis.

If you're going to go tubeless, check that your rims have raised lips adjacent to the wheel well just inside where the tire bead would sit. Idea is that if you get a flat, this keeps the tire more or less on the rim. Tube-type rims don't have this.

You may be fine without that lip, but it's good to know there is a difference.

I have never heard about that, thanks for bringing it up.

that sums it up pretty well.

I call them the trumpets of Jerico, two times around the block and
everything is in pieces.
