Worth Replacing Head Bolts on '75 CB750?
« on: June 18, 2016, 10:45:10 AM »
Hello, I recently bought a set of stainless allen bolts for my '75 cb750 Super Sport.  I just changed the gasket on the alternator cover a few days ago, and when taking out the original bolts I noticed the previous owner had used lock-tite or some similar blue substance.  I have always heard it is better to use anti-seaze rather than lock-tite on aluminum.  I haven't installed the allens yet, but I did replace the bolts on the alternator cover with bolts that weren't stripped (like the originals were).  They seem to be sitting fine.  My question is... since the previous owner used lock-tite, is it possible that they did this because they didn't know the torque specs and possibly stripped the threads on the engine?  I am trying to avoid a situation where I replace the engine bolts and now the bike leaks from certain gaskets because now they are not holding as tight. 

Your input is appreciated!

You will never have problems getting allen head bolt out, unlike the original JIS head.

I wouldn't bother with either antiseaze or lock tite, not on covers anyway.
