Bill, glad to hear about your experience with the "S" cams. I just received my cams from BW as well. How did you go about checking for clearance? I have yet to turn my engine over as I'm waiting for my new pushrod adjusters to come in since I accidentally broke one during the install. Also, did you have to do any machining of your case or cover? I found that my cover would not fit with the "S" cams and I had to use a dremel with a grinding stone on the timing cover to get it to fit flush again. I probably removed around 3-4mm.
thanks for sharing Bill and BW. This is great stuff. I kick myself for not finding a way to get those cams when they were available. Bill, do you use any decomp at all? If so, what did you end up doing (Adrian's mod comes to mind)
Wow Bill, that is some noticeable power... really good to hear. Sounds like 70-75 mph in 5th will be a bit more relaxed. You went back to the stock ECU, correct?The Harris Scrambler looks good as always.
That TCI [CDI] might have been faulty, Bill. The performance CDI boxes as on the machine I tuned should give 4 degrees more retard at starting and low RPM's and 4 degrees more advance at high RPM's, for a bit more top end go. Certainly, any tendancies to kickback on this testbed machine were eliminated by the new CDI box. Back to the 'S' cams, there are a number of plain 'Iron' and some 'Asbo' iron engine Bullets now using these cams and showing improvements as a result, as well as the AVL types they were mainly intended for. B.W. P.S. - very important - if any interference is noted between the exhaust valve and piston, the timing for this valve should be ADVANCED [move cam anticlockwise] to close it sooner and make more room over the piston going over TDC on the 'overlap'. Please, do not retard this valve's timing by mistake, or damage will probably result as a consequence. Retarding the inlet timing by turning this cam anticlockwise opens this valve later and will increase the space between piston and valve going over TDC on the 'overlap'.
