if your idle jet is too rich youll blubber a lot on cruise around 35/40 miles per hour,itll be a pain to ride and foul plugs,,everyone thinks they need more rich on the slow jets and read too much into these "plug chops",,less can be more!its always more of every #$%*ing thing,,i need more air and more fuel etc,,you dont,,if your not porting the head right out and using a super cam and all the rest of the stuff the stock #$%* works fine,,the biggest thing is all these improvements to induction rarely include an ignition upgrade,so many run points with all this #$%*,you cant even buy decent points now anyway,,plus the lobes on the advancers will have to be worn by now,,#$%*,,check the camshaft lobe wear but not the advancer lobes and still swear by points?ive never seen any specs for the points cam,,ill bet more than a few have less lift than they should,,if you want to soup up and havent considered electronic?sort your ignition first,,i always stress this.
