CB750KZ 1980 - I had the infamous spinning starter clutch scenario so I duly replaced the springs etc, threadlocked the 3 bolts and put back together. Now after a couple of normal starts the spinning has started again, could it be the unit where the springs etc are housed could be worn? Has...

Thanks for all your help guys along the way.

Heres my CB750KZ - as bought and almost there.....

Hi - I've just restored a KZ, great bike. I did a full strip of the engine so if you need any advice let me know.

Good advice amc49, thanks for that. I did notice there wasn't much thread. No doubt the head of the bolt will be lurking somewhere down in the engine, i'll need to find that too when its stripped.

Venting some frustration here guys. I've finished rebuilding my CB750KZ - started last week and it ran a treat. Started it again yesterday and heard a fairly loud crack and then nothing. Took the cam cover off and saw that the sprockets on the cam where leaning slightly, then noticed one of the...

I'm about to fit a Marving 4-2 exhaust to my CB750KZ - the copper exhaust gaskets just seem a tiny bit too big in that they dont fit flush against the head in the ports. The port has been cleaned and the gaskets are 45mm which i think is the right size and they pair up nicely to the downpipes...

Count me in

After much head scratching i replaced the rectifier and hey presto - all is now ok! There was obviously an internal fault in the unit.

My restoration of a CB750KZ progresses well, however after fitting a new battery i turn the ignition key and the main 30A fuse blows. Obviously a short but everything looks ok to me, i've disconnected all i can, ie left and right handlebar switches, all the lights, starter motor, rectifier etc...

Hi - good to see another UK entry on here, not many of us about. I think you will be ok with no changes to the jetting, i did the same on a 1980 KZ and it was fine.

Hi - did you get rid of the pipes?

Count me in too

Count me in too!

Count me in too.

Just beware that your tire doesnt wear through any loose brake lines, happened to a friend of mine who discovered it just in time!

Dont forget me "over the pond"

Looks good, you should be fine, watch out for engine rattles but i'm guessing you will be ok. I'm just restoring one that had almost 40k miles on the clock, the internals were great apart from a broken ring, they are great bikes.

Nice one greyhound ! - A Birth Year Bike - what a great idea - now i just need to find something from 1958 !!! All the best.

I can still spend it - even from the UK!

Hi all - i'm after a new chrome rear fender (mudguard) for my cb750kz - rare as hens teeth here in the UK - can you guys tell me if they are available in the USA? Aftermarket part would be ok.

Having just rebuilt a 750KZ '80 i will need to adjust the cam chains soon. My trusty Haynes says to do it while the engine is running yet i was always taught otherwise. Has anyone any tips or views on whether the engine should be running or not?

Yep - me too. Half rebuilt engine and months of work ahead. Keep focussed and as grepper says take plenty of photos and label everything up in bags, I even do sketches in a notebook for some things. It easy to think you'll remember wher it all goes, believe me you wont. Good luck!

Thats great - thanks for the info. I'm going to try that method. Getting it out of the frame was hard enough with the Jack method so i wasnt looking forward to putting it back in - your method looks easier, thanks again.

I'm currently restoring a CB750KZ - frame is bare and powder coated and the engine is almost ready to go back in after a complete strip down. Has anyone any experience on the best way to get the engine back in? Previous restores i've jacked the engine into the frame but i'm seeing people who...
