Eric would get that rear cyl exhaust closer to .000 Grin

You could replace the half rings and get there, but after a few revolutions you'd be in the same place.

I had it closer to zero on both (rear cyl-) and I had drag on the cam. Went .0005 at a time until it went away.

Here we are.

Chasing tenths out of this system requires a pile of shims and bucket of patience.

Problem is we can't measure the position of the actual working surface where the half-ring sits in a closer shim.
We can measure nearby but we're talking tenths not horseshoes.
Swarf and burrs and brand new halfrings aren't quite as flat as used ones.
And used valves don't seat eeeexactly the same every time.

Hypothetical scenario here...

What if some of the half rings were installed upside down? In other words opposite of the way they were originally oriented.

Theoretically, the new surface will wear in and the clearance will increase a bit quicker.

Theoretically, these would all be on the front cylinder. So they would, theoretically, be very easy to get to.

You're talking about .0005-.001.

If you wear in both sides on all of them, it won't matter anymore. Grin

Symmetry is good sometimes.

If you ride that thing like your KTM the half rings won't last long enough to matter which side is up. Evil

My first job, we actually had our own electron microscope.
I was amazed then and probably would be even now.

The running joke was if you couldn't find something wrong using normal inspection then the eScope could find a huge(1) _____ somewhere and that _____ was obviously the problem.

(1) Size being relative after all.

---------------------------------

Ideally, one would flip the half rings every 1k miles a few times then every 6k would be fine after that.
I mean people rotate their tires so it should be no issue.

This is of course the proper time to mention you could've fitted MBP collets and avoided a lot of these dilemmas.
But no worries you would have had other substitute dilemmas (We'd have seen to that).

Seriously the MBP bits are heaps easier to handle and cannot be installed upside down and on 7mm stuff that's even more awesome.

----------------------------------

Symmetry is theoretical, there's just varying degrees of closeness.

This thread is not for people that don't own Supersports to antagonize people that do  Kiss

None of you are wrong.

Unfortunately I do not own one of the handsome tanks so I've just got a bunch of SuperSport bits really.

DP did touch on a truth, all of the clearances seem to stay nicer longer if you don't rev the snot out of it.
Peak torque at 5k and peak power at 7k you can braap around all day long 3k to 6k with big lines and it's great.

I tend to run engines low. I cruise where it feels best. Generally right before the torque curve ramps up.

That lets me do a lot of acceleration/deceleration with just throttle without shifting
