Well the heads are off tonight , courtesy of Rx bob. Looks like the pistons are 2-3 thou above deck height.
Is this normal ?
Would explain the extra comp as otherwise explained.
I just checked my 2013 motor and they are at 0 deck height with a straight edge (using PVC to snug the barrels). I haven't put a dial on them yet because I want to check run-out at the same time (and I got busy plowing F'n snow AGAIN :banghead:).
Well we are averaging around 35 deg C day in day out. Some days 40 + .
I would love some snow.
You win some ! You lose some !
The deck height is above zero. Unlike your temp.
So much for mass production.
Cam chest open! Crank run out is .006. I would have preferred less I just say.
Would be curious as to how much less that .006 would be on a stand at the crank bearing surfaces.
Yes me. Too, but. Not this time around.
Next year crank out and a 124 kit perhaps or maybe some GMR pistons.
Hey Pete, why not turn your 107" into a 124? Too hot to ride ATM!
That a great idea Dave! It's only $$.
Three motors - one bike.
I would need to machine the cases - who would you recommend!?
:pop:
Seriously! What's with the popcorn, dude?
.006 is not out of the "normal" range from what I have seen. Heck my 2012 TK is out .005 with 30K miles on it and it'll be another 30K before I look at it again. I figure if it's moved it's done moving.
The only reason i would be concerned is if it was beat on with launches and hard stopping.
Well the bike is home.
RXBob is the real deal. Enthusiastic, honest and reliable .
The 660 SM 's are really exciting. 266e's were great above
3500 rpm. But these 660s are fabulous.
Time to retune!
I like popcorn, the red kernels.
And I'm following to see were this goes. I could just hit the notify, but that's no fun.
Least ya didn't mention me frying the drive belt on the test ride :idunno:
Well there is only one way to fry a belt Bob. Lol!
Will you be sharing a dyno sheet on your combination when it gets its tune?
The new valve train is quieter than the original.
SS roller rockers, AVV springs, GMR lifters and SE taper P rods.
Dyno results in a few weeks.
:up: :pop:

Another Auto tune run today.
I can now validate the claims of TR, Ray and others.
660's in a 120r - very impressive.
A word of Caution - there is no cure!
The cure is "More Cowbell."
Joe...I've never heard of that cure before :soda:
Ray
[attach=0]
It. Does run much hotter than before. A bit of a concern.
Whats the cranking pressure at now ?
We expect 196 psi CCP.
It should run cooler once you have a good dyno tune put on it.
Ray
Yes Aray, I will remove the fullsac pipe and introduce the VH power dual. Just have to weld in the wide band ports.
