its getting a bit a like two stroke versus four stroke dirt bikes debate,there both good,and both have different ways of doing the same thing,754,i set up points static as well and make sure its all good,then i shine the timing light and sure enough,they are both out a little so i "finalize"them,jonesy is spot on with older parts not sold so not made as much and up goes the price,ihwillys,my boyer ignition has the advance built into the black box and is supossed to replicate the factory curve,as far as it topping out at the full advance mark thats what it does,you cant tinker with it though!and petes1983,,get a proper sync done or do it,,an accurate bench sync is enough to get you running, and doesnt cater for actual vacuum,(which is being synced)that changes between cylinders as the engine heats up,,youll hear and feel the bike running much better,,,out of interest i replaced the points in my 308 cubic inch holden v8 years ago 92 i think,with a hall effect ,these have a bosch dissy standard and a bosch hall effect conversion was available,,the rotor has metal windows and a finned alloy box triggers the coil,,i kept the old points and condesor setup up in the boot for fear of all the above mentioned hassles and they are still there,i drive this car everyday its my only car,,and while not a honda bike it runs so much better ,,and the timing stays the same!murphys law,,if i throw them out the car will stop late at night ,raining with a flat cell phone,no coins,dressed like a bum so cant flag down help ,no torch(flashlight),in a bad neighbourhood.
