I traded bikes last year for a 1984 RGS 1000 that I have always wanted.  It was a nonrunner from negletct for 10 years.  Carbs have been rebuilt, fuel tank cleaned and seased, bodywork repainted, electrics sorted, fluids changed and now running.  Rusty chain replaced.  Still needs sorting.  This is my first Italian bike.  I have wanted a Laverda since I was a poor young man and now have a fast, attention-getting exotic bike.  Quite different from the brit bikes I have usually ridden and worked on.  Nice to have electric start, disk brakes, electronic ignition to make it more practical than my older bikes.

Welcome Chris.
Sounds like you brought one back from the dead.
It's a pretty rare bike in the US, no?

Welcome Chris! Your RGS will satisfy you in any respect but most probably you'll have to replace your ignition (if original) to get a perfecly reliable bike and a smooth engine. Fast, easy and relatively cheap on this 120 engine. In the meantime, you can just shunt the ballast resistors to avoid most of the problems (mainly fooling the plugs at low rpm).

Thank you.   Laverdas are very rare in the US, but still legendary.  I traded an Indian m.c. for this bike.  It was originally purchased in Switzerland, then by a local man who was a Laverda dealer.  It is nearly all original, including the ignition system..  It has been fouling plugs, so I may try bypassing the ballast resistors.  The carbs were restored by Wolfgang Hertner.

These BTZ ignitions are simply weak, especially at low engine speed. Add to that that the advance curve doesn't really exist (more like a "step"), you won't recognize your engine since you'll fit a decent modern ignition!

Chris,
You choose the right Italian bike and you wont regret owning a Laverda. I am sure that you will experience a bigger grin riding any Laverda than you have on any other bike.

Nice example Chris! Interesting that you have the plugs on the headers for a CO2 analyzer.

Any idea how to hook up a CO2 analyzer to the headers?
Right now, the bike is halfway stripped down for sprucing up, checking valve clearances, replacing wheel and yoke bearings, rebuild brakes, clean up electrics, etc.  It should look and run better by spring.

You can simply use a Lambdatester or similar, just plugging the sensor into the headers the time to check the mixture ratio.

About the valve clearances, I suppose that you know already that the cylinder head torques as indicated in the factory manual are wrong. Any torque above 25 ft/lbs has a good chance to strip the threads in your crankcase... This is the correct torque figure:
