i ran ada on my 1200 gp no problems i have 1 on my gpr no problems

a buddy has riva so far 2 cracked domes and i believe the head was replaced 1 time also

What CC domes are you using on your GPR and what is the compression.

connects/links three individual cylinders together. An assumption must be made that all three cylinders are identical. Unfortunately this is not always true. Cylinders can have varying heights and deflections that can cause sealing problems with the head. If the head is strong enough, (ADA heads are stong!) they can over-stress the casted cylinders and fractures can result (when cylinder height differences are present). ADA is renowned for building high quality products, I do not believe you will find problems with their product, but the fact is that the OEM does not always match ADA's quality standards.

I agree with cylinder height variation. I seen 0.005' difference between cylinders. In that case don't meter which head you using, engine damage will happen sooner or later. GJG

Gotta Agree with George-.005 difference will cause a problem with any head.

Makes me wonder about the harmonics of an engine that has a central case and individually girdled cylinder's and heads.

That is the difference between people who think that they are engine builders because they can bolt parts together and actual 'engine builders'! Who was it that stated, 'God is in the details!'?
