[QUOTE="joedrum, post: 17498, member: 98"] just to continue a thought dan .....it was obvious that theses cams from the 75 were running up and down on lumpy surface ....causing unequal pressure on the cams and rockers all the way to the valves ......when trued up the tension on the springs is smooth without ups and down over ridges causing ramping off the cams at high rpm which causes cam and rockers to crash into each other under different tension and causing uneven wear which creates even more lumpy wear .....and also causes loose tension on valve keepers and such setting up a failer machanicly.....on a smooth ride the cam and rocker just get smoother.....unless your testing the limits of the parts though drag racing and high rpm stupidity...... there seems to be no doubt that the 75 cams are right now smoother than the 1100 cams that were in it ......a smooth valve train is whorth some power and relibility in the pocket .....so in this respect the 75 cam job is an upgrade so far...... im looking out the window and its snowing .....i dont know if im going to be able to ride it today ....i still need to put stuff back together :mrgreen: [/QUOTE]
