'" '" '" " 0. C. - U SILENT SPARK ARRESTER J&R now makes a spark arrester/silencer combination that is so small and light it can fit most any machine. Besides being forest Service approved, it cuts ~oise appreciably. It's lIY," long by 2" diameter and weighs but 20 oz. The spark arrester part is the successful Krizman design and mated behind it is J&R's own .famous straigh t-through silencer. The silencer part can be rebuilt with a $2.50 kit should it ever become necessary. Cycle News dyno tests have shown little power di.fference between this unit and an open expansion chamber. Generally there was a slight loss at extreme high RPMs but a marked increase in mid-range horsepower. It is available from any dealer or direct. For additional information write: J&R Mfg., 6001 N.
