Motion Pro Restrictor Jets

Motion Pro replacement resistor jets are available for their SyncPro carb synchronize tuner. Ok, so do you remember when trying to synchro your carb's with vacuum gauges and the needles used to shake really bad? With Motion Pro's resistor jets, these little jewels will stabilize the vacuum 'pull', eliminating the shake, surge, and flutter you'd get. Put the resistor jets in the hookup line to the carb's—and voila! You'll get calm vacuum 'pull', allowing you to accurately adjust all the carburetors to each other. You may want to keep a spare set on hand, because your buddies are sure to want a set too!
