My I have NEVER seen so many different opinions on what to
tork a head down too. There just does not seen to be a manual
of tork spec's any were I have looked.
I have a Fred head & he calls for 80 inch lb for his heads. There was
another after market head that they recommended the 85 inch lb.
But reading new & ole posts I see as high as 200 inch lbs.I can see
why lots of studs go pop. What,s up with all this, really? I realize that
many of these heads & cylinders are not flat, & need to be lapped in.
But in all my years of messing with engines big & small I have never
seen so many problems as with these china made engines. I know
many of you guys come from other forms of motor sports as me.
But unbalanced engines to this degree, miss a lined ports, ignition problems
& so on just drives me nuts. But some thing as simple as a tork spec
sheet is be own any thing I have ever seen.
I got my tachometer today. Great (wink) now I must make a mount
to mount it on my bike, (smile). Then I think, China is the same country
kicking the rest of the world in importing goods. What is it I,m missing here???
