Did nothing to any Laverda except for putting the RGS mongrel up on the bike lift for a couple of little jobs before it gets it's newly painted bodywork fitted.
Main focus in the shed today was to get the Ducati MHR Mille running and take it for a roadworthy test so I can register it. It's been unregistered for a few years, but is now 30 years old so I can get it on cheap historic rego.
Put a battery in it and cranked it over for the first time since Easter 2014 when I had it on the track at Broadford. To my surprise it started on the first touch of the button with the old fuel that was in the tank, but it was running as rough as guts on about one and a half cylinders, backfiring, wouldn't idle, etc.
Carbies off, blew out all the jets with compressed air (one pilot jet was completely blocked with crud and needed poking with a thin wire) balanced the carbs which were miles out and re-adjusted idle speed and idle mixtures which were also miles out. How can carbies get so far out of whack while just sitting there doing nothing for a couple of years?
Took it for a ride, still not right, and the vacuum operated fuel tap wasn't working, which gave me a bit of an "aha" moment. Had a look at it, and sure enough, I hadn't re-connected the vacuum hose to the manifold - duh! So it was sucking air through the open vacuum port. No wonder I couldn't get the mixture right.
Re-connected the vacuum hose, re-tuned the idle and mixture screws, now running as sweet as ever. Lovely bike to ride. Looking forward to a ride on Sunday.
