81 GS1100 squish measurment

[gsryder]

Stock cams
MTC 7.8:1 forged pistons
Cometic copper gaskets (at factory thicknesses)
The block had approx. .01 thou cleaned off (ten thousands or less)
Dont know what the pistons were when I put it together (below the deck)

I just want to double check that I do indeed have the clearance that I need.

I assume the standard method piece of .04 or .05 thou silver solder down through the spark plug hole parallel with the wrist pin up against the cylinder wall, slowly crank over engine by hand, remove solder, measure the squished part of solder......at least thats how I have done it on other engines (they were two strokes though)

If the deck height is correct the valve height should be correct.....right?

Oh. You building a turbo?

install like 4 or 6 spacers on the cyl. studs with the base gasket/cyl. installed.
roll pistons up to TDC and check with calipers over the wrist pin how far down in the hole your are..
check them all and get an average.
you will be able to see how close things will or won't be.
no silver solder car stuff needed.

Yes but, that should not make a difference on engine clearances.
It wont be running any higher RPM than a stock bike would run, but may run a little warmer until I can get a water/meth system hooked up.

engine don't care..
your not putting anything exotic together.

In hindsight this would have been a marvelous Idea......but I did not think that far ahead that day.

Its already all together. Here is the engine portion -

Correct I just dont want to smash all my new stuff....before I get to ride anyway.

i have thrown 1166 10.25.1 kit together with stock head and cams w/ ff40 turbo kit.
8.80's@150mph no bars w/ slick long WB.
oh,
HD basket w/ helical gear.
20psi boost.
simple simple to make 200hp...and safe with 28 degree's total advance and C16 fuel.

Why Terry, your new avatar is perfect! I nearly peed a little laughing.

With my set up and being a road bike with a trip or two to the strip planning around 10 psi (unless I hook up a water/meth system) I will be real happy if I end up anywhere over 170. I think I may have some limitations getting to 200, small turbo, small plenum.....but then again this is my first turbo build so I will be real happy if it just doesnt blow up!!
