Wow that 635 has some aggressive Mid range valve opening and closings.
The 640 is better suited for me. Iím for All out that pulls hard to the end. I take the bike to the track now and then.

.640s will scream with more compression! 635s more suited for me.

I didn't do it with mine , but a little more compression will really make it shine they say. 640s at 10.8 still run hard , That's my opinion. Plenty of steam and not twitchy.

Yes! I've heard many great reviews on the 640 cams especially at 11.5 cr.

It's alive! Fired it up yesterday and running some heat cycles. They're going to put about 50 miles on the dyno and install a break in tune. Should be picking it up next week.
