Topic: Motor swap finally complete!! HURAHHAAA it riding time

[ElCheapo]

Finally got the motor swapped in the K5.  I scabbed the motor out of a 74' CB 750 chopper that just came in, that I rescued from a barn fire.  It was all good until I cleaned the dirty slut up. She had suffered a chain break at sometime as the was the normal case damage but was repaired well. Whats more is after I got it in place it found out via the front spocket it was a F motor. No biggie just swapped out the front sprocket and installed all the goodies. 6 hours round trip. Not bad I must say. Because I was like a kid in a candy store getting fatter by the minute, I had to start it before I got the HM300 pipes back on it. I expected super crazy loud. Instead I was greeted with silly other worldly boiling water sound. God these sound real dumb with no pipes  . Any way it started real easy. Like 1/2 a crank and it was running with no points tweaking.

At this point I have no oil or netrual light. Actually the oil light comes and goes. It does have a pressure gauge though. I am not even sure it is charging right now, BUT IT IS RUNNING!!! ANd it has 60 PSI for oil pressure.

A little more tweaking and it will be right. Then on to the fork seals.

BTW anyone who said the original failure was more, they were right. When I pulled the oil filter off, lets say the oil was glittery. I think I killed something big. Who knows.

good work!  Did the bike get burned in the barn fire?  Besides the awful noise, is running the engine without pipes in anyway damaging or harmful?  I've idled the engine for a moment or two without pipes on, I just couldn't take the racket.  Curious if this was in anway damaging.

My guess is you could bend a exhaust valve if you ran it too long. The danger comes with the possibility of cold air hitting a hot valve. This can happen when shutting the motor off. The chopper narrowly escaped the fire, just because of my timing. I think I drove 80-85 the whole way and had no idea why I was driving so fast, but found out why when I got there. I gave him a whopping $125 for the bike. I was able to pull the motor and use it in my bike. Then posted the remains with title on eBay and much to my surprise sold for just under $500! So the motor was a freebee! Plus when the guy shows up tommorow to pick it up there will be a chromed out 550 motor and a complete kz1000 motor worked into the trade. Sweet

Is 60lb of oil pressure normal? I'm looking for an oil pressure gauge and they have 60 or 100lb gauges. I guess I should get a 100lb one? I want to get a white faced one but I would like my tach and speedo to match. Anyone know of a place to get a white faced due south speedo and tach decal with a 9500 rpm red line?  I know I'm a chuckle head!

Pressure relief opens in the 55-65 psi range

Running any kinda motor "open port" is not the best thing in the world..
