Question 1: 1982 CB900c Muke inside of the intake track. Stuck Gas lock and some much needed help on sealing a tank.

Answer: From the images it appears that gas has been sitting inside of the intake and possible cylinders. You need to do a compression/Leakdown test. Getting your lock undone depends on how stuck it is but you will likely need to drill it out and open it from the outside in.

Question 2: Previous question feedback from Episode 2 1985 VT twin 500? 700?
Having low rpm throttle issues in all gears, but found an issue with the carb bodies.

Answer: Solve the carb body issue that hinders you from performing a proper carb sync and let us know how it goes!

Question 3: 1982 Kawasaki KZ750 LTD H3 harness issue. Possibly with a short to ground?

Answer: Pull all fuses out of the bike and start testing one by one. A possible short to ground on wires leaving the ignition switch could be your issue.

Question 4: Honda CB750 1981 excessive engine noise from upper to middle lower part of the engine.

Answer: Sounds like a lot of cam chain noise, could be some piston slap as well. Pull the valve cover off and check some things over. Might be a good idea to invest in a cheap borescope and look for any wear on the cylinder walls. Compression test on a cold motor will also show some results. We also did not know how many miles were on the bike.
