Re: What did you do to or for or with your Laverda today?

let it all dry out, plugs back in, float bowls back on, hit the start button and it burst into life for about 2 seconds then died again. Turned it over for about 30 seconds not a sausage. Checked the bowls, they were full of fuel again so it's not a fuel supply problem. Went over the wiring and couldn't see anything obvious, took the spark plug caps off and stuck plugs in them and they are sparking just fine. Very strange!! Might just set fire to it and claim the insurance.... >:D
 
Have you checked the air filter and/or the induction system, seems you've checked everything else.
 
Is it using fuel in the float bowls and then cutting out? i.e. blockage in filling the bowls?
But you say the plugs are wet when you check, suggests loss of spark.
 
Flushed through the brake fluid on the front of the SF2 to renew it.
Probably hadn't been done in 3, more probably 4 years on a machine that sees regular use.
It's a 1/2 hour job, start on bleed nipple furthest from master cylinder and pump until fluid comes through clear.
Then progressively flush nearer and nearer master cylinder. My machine has the twin nipple calipers making it a bit longer.
Probably about 20 to 30 cc in the whole system.

The brake was needing 2 applications to bite. Trip into Belgium tomorrow for a beer and snack. We'll see how it feels.

Oh fuck, fuck fuckity fuck fuck fuck fuck. Back and forthing with Red for a few hours, checking everything, and no problems found, was about to head off to the pub to drown my sorrows... thought I'd drain the oil as it was due anyway, out comes about 7 litres of petrol. I know I left the fuel taps on for a few days but that's never happened before when I've left the taps open! I think I've broken it......

Will take it over to Lav HQ next weekend to see how broken it is.

FFF

Time to put the Beemer back together and put Lav stickers on it for the rally, no one will notice I'm sure.....
 
I don't reckon you'd have done any harm Drikko. Roller and ball bearings are pretty forgiving. You would have had about a 2:1 mix in there. 2-strokes bearings get sufficient lube on 25:1 or leaner.

You must have had oily petrol getting past the rings making it way too rich to run.

Just fill it up with new oil see how it goes.

PS: More years ago that I care to remember, I noticed that my Honda 750 (K1) oil light was coming on at low revs. It was during a period of hot weather, so I just thought it was higher than normal engine temperature making the oil a bit thinner. I kept commuting on it every day for a couple of weeks before I got a chance to check it out. When I did eventually drain the oil, it was half petrol like yours - very thin and runny. I put fresh oil in and it was just as good as it had ever been. Oil light went back to normal. And that's a plain (shell) bearing engine!
 
I might just leave that till I sober up next week sometime :)

Rocket Rod (Alpino) just rang with similar advice to flush it out then fill again and give it a go.

I asked Jimmy if there was any untoward smoke while he was following me (not the usual order) last weekend and there wasn't. Hopefully all good!


 
Well with the encouraging words I forsake the pub trip for a bit, went and put fresh oil in and a new new set of sparklers and it burst into life! Still feels like it's running rough though although it always does when it's cold. Got that Subaru brap brap brap offbeat sound. Will change the oil again when I sober up and take it for a spin. Forgot how fucking loud it is in the garage without a helmet on!!!

Now I'm definitely off to the pub, although much happier :)

Thanks Red, Rod and Cam for the help, you folks are all awesome!!

Cheers
 
Yeah 7 litres of fuel in the crankcase is nothing to worry about. Levo leaves that much oil behind on the road every time he takes it out.....
 
All fixed! Going like a 180 8).. Made a few changes to the ignition set up.  Even the GEN light is now working !!!    :o
 
I spent a bit more time and energy on my 81 Jota that I bought new that is now passing 230,000ks a new set of billet cam blocks (they are the ducks guts and the answer to a whole range of issues) and a set of nology coils and sync'd the mikunis whoa she has some mumbo that old girl.
:D :D :D
 
Had enough time this morning to ride down to a nearby Show & Shine. Didn't have enough time to stay and enter the Lav but would have stood out like a sore thumb. Even where I parked someone was telling the owner of a nearby Hardly how shiny his bike looked...........
Anyway, mainly old cars but certainly size seemed to matter...........
Do all Boss Hogs come with their own transport:-

And this certainly looked the part:-

Didn't have time to wait for a clear shot, I think he was phoning a client........

 
Went for an afternoon meander on the SF2 through belgian flanders. Nieuwkerke, Loker then on to Ypres. Stop for a beer. Lovely weather. Lots of foreigners about on WW1 tourism.
After Ypres, stopped off at Kemmel for another beer and some bread and ham.
Brakes a lot better. Still wooden. Brake fluid definitely needed changing though.
The whole system would need overhauling from master cylinder down. Maybe change the 41 year old brake hoses as well.

When I got home, I reassembled the cleaned dynamo with new bearings.
Had to do it twice. First time, one of the long through screws ripped out the felt pad. Start again. All's fine, only, with the new bearings, the drive side of the shaft still moves lateraly by 3 or 4 mm. Something I haven't understood there.

your timing was perfect for quick replies, I was on the computer yesterday for 8 hours straight writing out Blab's invoice for his Jota  :o

:D
 
It will be a shame to see Blabs bike gone.... it was a great dumping spot for miscellaneous costs.... :-* :LOL:
