Hey, I am a 14 year old who has been watching your videos for a while and they have inspired me to do a similar build and just today I bought a Yamaha xs750 special That I am gonna build into a cafe racer I have built bikes before but nothing like this so it is going to be a learning experience but I love the video keep up the good work😀

If I ever get to interview apprentice candidates for heating/plumbing this would be one of my main questions...'have you ever rebuilt a bike/scooter engine'. Because to me if they have got an interest in this type of thing then that proves they have mechanical aptitude. I am not interested in Gcse's and phd's...its that aptitude that is the real gold. Nice video btw! :) bet they are good solid engines.

A few quick question: 1. What year is this Honda? 2.What was all replaced during the rebuild? 3. Were these parts readily available? 4. How much did the engine rebuild cost? 5. How many hours were out into the engine rebuild? Amazing work, and inspiring content. Thank you for being a teacher and not pretentious like other builders.

@@forthebold I just bought a 1980 CB750F that's spewing smoke and has very inconsistent power until it just gives up. The previous owner says it probably has a bad cylinder, or at least cylinder ring. Is this a doable job for me, an aspiring weekend motorcycle fiddler, or should I just use the bike as a parts back-up for my CB750K?

Did you have to fully install the camshaft holders to get the exhaust camshaft chain onto the sprocket? I'm rebuilding this same engine, trying to follow the service manual closely and am having some trouble getting the camshafts back in. Don't want to mess up my valve timing. Any help would be much appreciated, thx.

I did it all at the same time if that makes sense, got the teeth in place and then clamped the camshaft clamps down, there is a separate video of that part in the list.

3:06: Did you put the cam shaft brackets in a box without marking them? That would be a bad idea: Each one needs to go exactly in the same place again.

Each cam shaft bracket is stamped with a letter from the factory to be put in the correct position and in the correct sequence.

Not being a rider, I am curious about the trend in painting the engine....specifically the fins on the cases. Does the paint reduce the ability for the engine to cool off via air flow over the fins?

Doesn't alter anything, purely looks, some do polish the fins to possibly allow the ends to cool, but very minimal change

Reason for the rebuild is it never quite ran at 100%, carbs leaked at idle, but were fine under load, still having same issue after rebuild...
