Hello everyone!
I've got a 1980 cb750k bobber project that I picked up on the cheap.
The previous owner decided to rattle can bomb the entire motor and carburetor. The carb is flaking paint off like glitter.. You touch it and you get a nice paint chip dust choosing I whatever it touches lol...
Cool deal. Thanks for the tips.
It runs with no noticeable leaks.. Yet. Lol.
Need to make a new thread though.
Can't seem to get her to idle.
Ugh.

Von Braun,
Thanks for all of the very informative posts!
Where to begin.. OK.
The gasket kit I purchased originally was an aftermarket NOS kit from 1971. Company logo on the packaging is "SCM". I myself have never heard of that gasket manufacturer but I figured it being older it should...
I'll definitely check the squeeze ring thickness in those two locations.
As far as the o-rings causing the torque to be uneven- I would it's not that considering the rings were also supplied in the top end gasket kit.
The only discrepancy that comes to mind about this particular gasket. The...
Well, I ended up getting a different set of piston rings to go in the motor. They were clearly marked this time.
Got the motor up and running to discover oil was puking from the head gasket seam.
Torque of 14.5lbs is on spec with the manual.
Decided to remove the head yet again. The gaskets...
Yea. I guess at this stage, I'll run the rings and see what happens.
What a bummer, I tried to purchase from a US source so I could bypass the 2 week shipping time from Thailand.
I guess some things are better sourced from across the pond.
On a side note.
I had 85 and 90psi compression on...
I pulled out a 30x loupe and inspected the rings. Both are identical.
The rings I removed had a definite profile difference.
I guess I'll know if I'm hosed when I start the motor. :/

Hello everyone,
Recently started a top end rebuild on my 1973 Honda CB175.
Purchased some new standard size ring sets for the pistons and noticed both the compression rings are the same profile.
Anyone ever experienced this with a CB175 ring set?
Thanks!

Hey everyone,
In the middle of doing a rebuild on a motor that needed the top end rebuilt.
I honed the cylinders for new rings, hand lapped the valves, and hand lapped the head gasket surfaces on a granite surface plate.
I'm ready to reassemble the top end.
My question is regarding using...
