Twistgrip and throttle cables

Little can be said about twistgrips and throttle cables that has not already been said in the Maintenance section. Perhaps the major complaint with Laverda twistgrips, particularly the ones used with Nippon Denso switch gear, is that they are too slow. The earlier throttles used with pre-ND switches were made by Tommaselli and the complaint was not so serious. For those who worry about a slow throttle it is possible to remove just the ND throttle, retain the switch and fit a Tommaselli throttle next to it. Other throttles such as the Futura (for a Suzuki) should work too.

All Laverdas have used single throttle cables, except the 1973 SF with Lucas switch gear which used a two cable. The single cable always goes into a splitter on the Twins located under the tank. This then divides the action to two cables which go direct to the carburettors. The single Triple cable goes straight to the triple carburettor 'frame' except on 1973 1000s which goes to a splitter into three cables. On the two cable, one obviously went direct to each carburettor. Don't forget to lubricate the cables, use Vaseline or light grease in the twist grip body and don't fiddle with the splitter. It has a very strong spring fitted in it which is difficult to handle.

traditional fashion being fitted through the top yoke and down the steering head. An alloy knurled top nut adjusted them.

The relevant drawing shows the component parts and how they fit. The key to the whole thing is the clutch' plate or friction disc which sits just under the steering head. In time this could wear and reed replacing. Otherwise, the damper can be left alone and only removed if the top yoke needs to be removed. Other Laverdas were not fitted with a steering damper and for normal usage one is not necessary.
