Video on Youtube CB750 rebuild
« on: September 13, 2015, 08:41:17 AM »
 Watched this video series on Youtube.

Interesting way of putting the pistons on rods and then clamping to the crank afterwards. What do you think? I remember that with the 400F there was a generous lead-in on the liners and it all went together pretty well the conventional way.

Yeah, Dino is a member on this forum.  He does an excellent job with all of his Hackaweek videos.

+1 on the Dino videos.  His 750 project is sweet as is is Saber project he finished previously.

Must agree .. I found them really informative in the run up to assembling my '69 750K0 diecast motor. It's a brave man who puts himself forward as there are so many 'experts ' gonna shoot you down. Definitely going to make a donation to his efforts. Didn't realize he is a member here.

Very interesting stuff! He does get a helper when putting the engine in then frame...
I like the text caveats when he's made a "mistake", he doesn't reshoot the sequences but he does tell you about the problems that have likely been commented on.
I do hope he went back and put the O-rings in for the 1-2 cam tower oil passages... they're missing when he puts it on in the video.

He did! THat was the next video. He took it all back apart to do the o-rings and metering jets.

I watched his Clutch several times, made me smile seeing he made same mistake as I did - installing the clutch release 120 degrees off.

Something you find out when trying to hook up the cable, LOL.

Happened with my K2 assembly as well, and I'd somehow missed his clutch vid. My fav is the shifter assembly step by step  8)
