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

Finally finished up on fitting some new fork seals to the Jota,have to say they were the easiest seals i have ever had the pleasure of removing,..... big thanks to Ducati Paddy for supplying me with spares. (bigthumb)

First time I have had the Marzocchi forks apart,found them fitted with two seals in each leg and lovely brown oil......and doesn't it smell!

another job done and experience banked.

 
No sooner am I home than the carby replacement begins.

Dellortos off, I discover oil leaking around the bottom of carb 1 and 2 inlet stubs, and a split in the gasket between stub 3 and the block.

Having thought ahead, I do have replacements.

Backing out the lower stud from cylinder 2 was easy enough using 2 nuts. But 1 and 3 wont shift. Any tips?

Removing the lower studs is necessary to install Red's angled stubs...

 
You could try:
1). Penetrating fluid (the proper stuff, not WD40), then try again.
2). Heat around the stud while trying to undo (there might be Loctite in there).
3). Shock load the stud with a smallish hammer on the end to break the bond, then rip into it.
4). Try a bit harder with double nuts.

Double nuts are just turning together and the technical tap didnt work.

Off to get a blow torch tomorrow...
 
Perfect weather, 69 and Sunny, here in Chicagoland so I took a break from rebuilding the triple's carbs (parts on order) and after some fiddling, including replacing these fouled plugs and rummaging through the points plate, a few turns here and there on the carbs and some necessary detailing took the 750 SF2 out for a spirited flogging. Wow, I wish I could duplicate todays weather, because everything seemed to be correct conditions wise and over the quick 93 mile journey the only complaint is I had to come home to help out around the yard. Midrange and up the throttle response is getting better, I still think there is more there so after the 3CL this bike is going to get a going over, too. Ride safe!

I weld a nut on to the stud when I find studs that are not keen to be liberated from their position

when installing the Mikuni's do not use the heat spacers, they are not needed as the rubber couplings do the same job

 
Blowtorch applied, stubs out, studs on. Mikunis were very easy to fit.

Started off the button without choke.

Took her for a spin down to Stonhenge and back. Massive improvement on throttle response.

Sadly found i had evolved a cam cover oil leak. Suspect its due to changing out one bolt to fit a new one that secures the bracket holding the carbs
 
When I fitted Mikunis to my Jota, It felt like it had better throttle response too. But putting it on the dyno revealed bugger-all difference in power from the Dellortos. The power curves were pretty much identical. I reckon the different feel was because of the lighter throttle. It was easier to twist it open so I was probably opening it further!

Mine needs choke to start and it coughs and splutters a bit until warmed up.

Fuel consumption is improved with the Mikunis.

Not many. I used a second-hand set of Mikunis that I got pretty cheaply. They were on a bike that had been left outside in a wrecker's yard, so they looked like shit. Also, one of the float bowls had burst open from being full of water and freezing in winter (hence the cheap price), but it wasn't the pumper bowl so I could discard it. There was a lot of crud on the inside too, but they had hardly any wear on them and cleaned up nicely. One of my cheapskate gambles that paid off.  :D

Come to think of it, the brand new Mikunis on my RGS mongrel were even cheaper. I got 3 right-hand carbs from Red for a very reasonable price.  The right-hand one is the carb he discards when converting the 4 carb setup to 3. There was a bit of work involved in converting them to a Left/Centre/Right set and turning the centre one into a pumper (and another gamble because I was unsure whether it was do-able) but it all worked OK.

Now that I know it's possible to use the left-over #4 carbs, I'd be keen to get a box full of them and make up some sets to sell. The only issue is that they don't come with all the shaft gubbins like springs, cable cranks, etc. (Red re-uses that stuff on his conversions). The issue being that some of those parts are no longer available separately from Mikuni, so I'd have to get them made. I was lucky to find some second-hand bits on ebay for my carbs. I did have a go at casting up a cable crank at home (the Mikuni ones are cast alloy) but it was an abject failure. I could make them from billet if I had a milling machine ... 
 
My Eagle has gotten some well deserved attention this week. A good cleaning and polished the shiny bits. Then adjusted the valves and timing. Timing was a bit retarded but now that it is corrected it feels much more crisp and cruises 70+mph easily! Not bad for a 50 year old lump.  Now I just need the seat back from the upholsterer and all?s done for now.
