RGS engine mounts

[murphus]

Are engine mounts for the RGS/RGA/SFC1000 available anywhere? I think mine on my '83 RGS are giving up the ghost; wouldn't surprise me, it is almost 40 years old. I'm finding the RGS is getting more and more vibratory with time and miles, of which it's now accumulated almost 75,000. Valves are in adjustment, timing good, carbs synched. Carbs are also displaying more unsocial behavior. Runs like the proverbial scalded cat on acceleration, bit lumpy at lower engine speeds and just doesn't like trundling along at small throttle openings. Give it the beans and it soars. Jets have all been replaced in the last few years, etc., Fires right up, no vacuum leaks that I can find anywhere, I wonder if the slides are starting to wear and assume that goes for the bore as well? Or maybe it's the reverse? Took a lovely 120-mile ride today with my son Charlie, he on my '88 Paso and me on the RGS. We swapped bikes mid-ride and the Paso was in comparison so much smoother it surprised me. Lovely ride, regardless. Perfect weather and miles of fabulous 2-lane backcountry roads.

Andy Wagner has them …https://www.laverda-paradies.de/article-52-65-en.html

have you checked that the mounts to the frame bolts are tight especially the lower rear ones … as they can work loose and then it feels kind of weird.. also if you have too much tension on the exhausts can affect…..another thing is that if the chain is too tight or out of alignment can also affect them…

Second that....lower rear ones often are loose.

Murphus, get yourself a set of Mikuni 36mm carbs with according 2 way throttle cables and put the Dell'ortos on the shelf. They were great carbs at their time but the design is almost 50 years old. Sure you can make them work again by replacing the sliders, adjusting them etc. etc., but they get out of sync the moment you start the engine due to their fragile connection design. I have even seen a set rising the sliders in different speed due to the complete setup being bent. How do you synchronize this...??

So - if you want to keep everything 100% original, send the carbs to a REAL Dell'Orto specialist and get them completely stripped, ultrasonic cleaned and everything fixed and renewed. Will cost you around 600 - 700 bugs I'd say. Or put them on the shelf, get a set of Mikunis set up to match and enjoy less fuel consumption with more torque and power and a more snappy throttle reaction with smoother running for about 1.000 bugs.

That said, make sure the valve clearance is adjusted, too, and your ignition setup is perfectly working (if you still have the pickups in place, check the cables! The insulation on those tend to brake and peal off of the cables, which results in bad/wrong timing and can also cause vibrations...).

Will check the mounts. Had the engine out a few years back and pretty sure I haven't checked since. And yes, carbs, I've been pondering switching to Mikunis. I've always had this thing about originality, but it can get in the way of actually riding and enjoying the machine. What/who is the best source for carbs and attendant cables, etc.?

pattern RGS engine mounts have been available for a while, one company even offered them in stainless steel as well as black painted steel, my impression of one set (black ones) was not good, the welding of the tube to the plates was very amateur and should never have made into mainstreem use, a crowbar was needed to make them fit (where they not central???) and I am sure the rubber was either in tension/compression or not the right stuff, because vibration was strong, fortunately a used set from a badly wrecked, ultra low mileage bike, became available (genuine stuff) and fitted wthout hassle and the bike then was back to normal, just a great whizz at 160KPH is one of them!
