Door hinge for frame seat hinge mount CB750- neat fix !
« on: October 28, 2017, 02:53:26 PM »
 Maybe this repair may help another soul. Quick backstory is I bought this 1975 750 4 years ago or so on the day before Christmas to help out a dad who needed to buy kids presents etc. The bike came to me in pieces and the engine had suffered a cam failure from a blocked oil jet. Pretty epic damage on the can and holder  ;) Anyways fixed her all up this past winter with an F model cam and holders etc. etc. and it has ran well with no problems. BUT the dude cut off the seat hinge mount on the frame to fit a 'custom' seat. CRAP !. I showed it to a friend this summer while we were doing a ride together who is an ace mechanic,restorer,fabricator etc and all around nice guy. His red K5 you see in the pictures won bike of the month here in the past. He called me up and said bring it out as he had an idea.
  Looking at his 750 bike he found a couple of steel door hinges he had laying around and proceeded to start cutting trimming and reaming and welding and whipped this solution up for me. The end result came out very nice with a minimal amount of hassle on his part. Nice to have a seat that won't fall off and feel lucky to have talented friends to help me out. Thanks RL !!  Of course it had to rain while hauling it. Another CRAP !  :D :D

  Here is another little project he is fabbing up that he is getting close to finishing. Its a cb350 I sold him on the cheap a couple years ago. He's already had offers to buy it and its not even done yet   :D  He does not do these to resell though. This picture on his shop wall is his wife's mother that he had blown up,guess she was kind of a wild girl back in the day  :o Picture was taken in Vicksburg Michigan. I also like this one of these 3 kids riding on some type of a possible carnival ride. He thinks it may be a European scene.

Looks good Eric! I googled that pic, it must be pretty famous, it came up right away! ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

 I was watching some kids faces this fall when I went to a county fair where they had an old beat up motorcycle kiddie ride. My wife and I got a kick out of watching their excitement when the 'Harley's' would wheelie and take the jump. I'm still glad though I was a kid in the 60's and 70's  where you could easily still ride a real dirt bike in oh so many places and raise a little hell !!

Ha ha, I'm looking at a Honda QA50 on ebay in remarkably good condition Eric, nowadays I way probably twice as much as a QA50, but when I was 10 or 11 (1970/71) I swapped my bicycle for one, and would really like to have another one, just to re-live those memories........... ;D
