Topic: Megacycle no longer selling billet cams for old Hondas

  I'll let you know in a few months Gordon. Replacing my "65" with a "75" using same carbs and only 14cc bump(850 instead of 836). Once I get that together I'm going to put the "65" cam in my other bike and take out the "63a". Both bikes will have damn near the same set-up for a decent side by side comparison(Once I get another rack of CR's ).

Jay,
if you know of a machine that will index and cut the tooth, over 20 times in 10 seconds, can you share the make and model?

..off to count the teeth..



I counted.. looks like 13 teeth.. I was thinking that they machine journals, sprocket shoulder, tach gear, before they sell the blanks to the grinders.. and if it made a significant difference in price it may make it more viable..  but it sounds like supply is in place again..

I know this is not related, but I just wonder who has ran the 125-65 versus the 125-75 in exactly the same set-up.

When deciding which components to buy/match/use, I asked my head porter for recommendations. Since I'd established that I wanted a "great" street bike. Not a 1/4 mile burner, but one I could pull off of corners with and still have pull at 8,000 rpm (stock rods at the time). What came out was a 125-65 because it would pull strong from 3,000 rpm up to well past the redline with his porting work. He hit the nail on the head.

I do have to wonder though how much I'd have lost on the bottom and gained on the top with the selection of the 125-75. His point to me was that I'd spend less than 2% of my time up at the redline and above, but 98% of my time everywhere below that.

I'd still like to know.

Gordon,

As you know, I am running the 125-75 cam.  From what I can tell, the 75 is still very streetable.  The power is great in the mid-range - where you will be riding most of the time.  But, the 75 has the added bonus of getting better up top.  I pondered the 65, but the 75 seemed like the better choice at the time.  I am happy to say, it was.  Besides, these engines love to sing fast.

For my personal riding style, I prefer better power on the bottom end (I'm used to thew torque of a V-Twin).
