I'm still subscribed! Just got the performance head I got from Ed on my 1085 S yesterday Bruce. Ported, megacycle cams, oversized valves, 34mm flats. Making just a tick more power :dancing:

Joe I'll bring it up next time I'm your way so you can test it out yourself :)

I was going to ask you about those cams. Any idea on the lift? Are you running shim under buckets? Did you degree them in? If so, at what degrees?

OH, and of course, this thread will still be for "the beast", just with different frame and body work. :D

.400" lift. Not running shim under bucket and did not degree them in.
 
I acquired some Andrews S2 cams, 390 lift. So should be perfect for what I want. Waiting on those and a few gaskets, and I should be ready to button up the motor.

You get the matching springs Bruce? My first S had a bunch of broken valve springs along with hipo cams when I got it, and I'm pretty sure the PO installed the cams with stock springs which proceeded to self destruct. Also, Megacycle calls for .006/.008" clearance for their cams, so I suspect other hi-lift GS cams are similar. This is significantly more clearance than stock and something to be aware of. If you already know all this please dismiss.

Although Andrews says that stock springs ore ok, I'll be putting in some fresh aftermarket springs. They are showing a .004-.006 lash.

Here's their spec sheet. I thought it was cool that they show what the stock numbers are...I always wondered....

BTW here is the Andrews Cams installation instructions with some relevant information. Check out Page 3 (orange sheet) at the bottom of the page. Andrews recommends setting lobe C/L 1/16" below the the cylinder head surface to achieve a 108/110 timing. So last time I degreed my Andrews S1's I found the casting marks in both cams; the raised casting mark is actually pretty fat. I used their method and measured the 1/16'" down with a Mitutyo digital caliper. I then checked the timing with the wheel and was quite suprised their method repeatedly measured 106 to 108.

I think this technique will get you in the ballpark real quick :).

Thanks for the info!
 
The beast I built and ran on the street back in the early 80`s had a 4S Andrews intake and a 3S Andrews exhaust cam. Coupled with 33 smoothbore carbs and an 1175 MTC kit. The piston kit was listed in the catalog as being like 10.5/1 but just looking at them I would have guessed them to be around 12/1 ......They also had oversized valve pockets....I ran a mix of premium fuel and av-gas in it. 3rd gear roll on wheelies were seamless and almost undetectable until the horizon told you otherwise.....The downside was overheating in traffic and keeping the charging system rotor on the crankshaft....It was as fast as a modern day Busa, but the reliability factor was poor....It quickly became a track only bike...Billy
 
I got my HD springs from WebCams and they also inspected my Andrews cams and checked the specs on them @ .050

Andrews S-2 Cams


Specs @ .050 per WebCams

Duration: 261 in/ex Lift: 390

@.020 Duration: 290/292

Also, these cams are not hard welded, they are billet.

Thanks to Dan Ruddock for getting me the springs and the inspection done from WebCam. :clap:

I hope to find some time this afternoon to put springs in and cams on, and this motor will be ready to install!
