[QUOTE="riptragle1953, post: 42087, member: 2328"] There's a bunch of people wanting specific details concerning why this bike goes fast...... removing lots of little losses can add up to one big gain. So now we know having the valves following the cams at 100% adds a bit of power. As far as that other set up goes you couldn't mean wearing deep grooves where grooves shouldn't be is a fine design feature? Maybe if you rode long enough the rocker would pop out of the top of the head! The only heads I've seen without rocker tunnel DAMAGE were new heads. My usual fix was sleeving the tunnel with bronze.... it is now true and round. Choosing a tight fitting bush and rocker lock nut and now the assembly can pass as a good repair I have yet to hear that flexing in the valve train was a good thing. Now if I get in the mood I may speak of the special Russian submarine developed titanium push rods and custom light weight adjusters [/QUOTE]
