A65 competition rocker arms

[Mark Parker]

The std rockers work well with mushroom headed adjusters. I made an alloy block for my A65 and made C/molly pushrods. I had trouble with the std adjusters digging holes in hardened lash caps, even running virtually no clearance. The mushroom headed adjusters prevented that. With offset rocker buttons it has .410 lift from the std cam profile.

What it sounds like.

Hi,

I have been running my long stroke 750 with the above featured rockers for about 3500 miles.  The engine goes well and pulls strongly two up and pulling a loaded trailer.  It has a single 30mm Mikuni and is on std primary with a 21T gearbox sprocket.
I do not know what the max valve lift can be but with as rough measurement I reckon I have about 10.5mm on the exhaust. 
I do not have the means to do it but it would be interesting to alter the lift by adding material and re-profiling the rockers.

Dave.
