Hey BW

      You made this old mans day with the video..  I feel like going out and dragging some knee. What sticky tires

do you like for the 535s ?      What gas in UK ??       Some good valve springs in that 350 !!  And The Sound at 10.

Thanks BW

I can save you some time.
All Enfield 500/535 models have flow curves that flatten-off at .350" lift. They don't back up at higher lifts, but flow doesn't increase more than a few cfm above that lift.
So, you can lift it more, but it really only extends the area under the flow curve up to 350", for all practical purposes.

To get more, it needs porting.
