Hi All,

Today, I spent £50 on this non-runner, in the hopes that I'll get it going and still have some money left for a few tasteful mods!
I joined this forum recently, knowing that I was buying this.. and so I'll be looking for help, advice and opinions!

I'll show the different stages on this topic feed for those who are interested, and also for me to look back on smile

index.php?t=getfile&id=21160&private=0
Since taking the photo, I've removed all of the rusted chrome leg guard things, the front mud guard and the plastic covers on the side.. just to tidy it all up a bit!

Not sure what I plan on doing to it yet.. perhaps flat-tracker style.
Please let me know what you all think!

Thanks,
Luke

I'd start off by becoming really friendly with your local polisher, he'll get his second holiday this year after all. Thumbs Up

It'll make a change to have an actual Honda being worked on. Laugh



That is going to need a full strip, depends of course on your full intentions, I guess it's been standing for a while?

There probably won't be much that doesn't need a degree of work, but ultimately you should at least strip it as it gives you an idea of the condition and integrity of the whole bike, every inch.
Just riding something like that in that state is kind of an unknown and liable to bite you in the arse fairly quickly, other than that the world is your oyster rodders!


Post as many pics as you like fella, folk won't always respond but many will be nosey.

Keep it standard if possible as all the right bits are there. Need to pull it apart to see the degree of work needed. Decide now if you are just going to tidy and use or a full pull apart and go from there.
Engines were always very good and reliable as long as the oil and filters changed regularly. What is the milage on the clock?
Youy will not make money on it if you restore it as the cost will outweigh the value, but as a project, it could bring you a lot of satisfaction/frustration. Thumbs Up
I hope you have a lot opf tools and patience.Good luck and keep the posts coming

Quick update..

Here's a pic of her, tidied up a little bit! The mufflers were rusted out where the kickstand and kick-start had bashed them.. so I cut them off.
index.php?t=getfile&id=21166&private=0

.. and here she is with no engine.
index.php?t=getfile&id=21167&private=0
(Not looking forward to putting it all back in!)

Also.. there's half a spark plug wedged in the cylinder head. Wall
I bought some 'screw extractors' to remove it but no luck. It's in there good.

Nothing is ever straight forward.
Oh well. Onwards and upwards!

Remove the head and take it to a machine shop. You are going to open the engine anyway to inspect/replace bearings so it should not a big issue. You may also have them fit a new threaded insert while you are at it.

That's it fella, get stuck in.

There will be a number of issues you'll come across with a bike of that age so expect them and you wont get too disappointed, everything can be fixed.


It''l keep you busy and empty your pockets. Thumbs Up

Anyone know how to remove this kind of chain link..?? This is part of the cam shaft in the head.
I'm pretty stumped!

index.php?t=getfile&id=21173&private=0

I need to remove it so I can free the chain and pull the blocks of engine apart. Confused
Cheers!

That is commonly known as a rivet/soft link.

Unless you think the cam chain is goosed you wouldn't want to remove the link. There should be a cam camchain tensioner which would allow you to get some slack on the chain itself, it may not be enough to remove the chain from the sprocket entirely, you should also slacken off the tappets unless the early CB engine were pushrod (can't remember myself) loosen the cam cap bolts, that'll give you some movement of the cam, all of the above should allow you to remove the cam without cutting/splitting the chain.

Unless I totally misunderstood your question. Wink

As above, but undo the two bolts that hold the sprocket onto the cam. That will allow you to pull the cam out through the sprocket. Don't forget to hook a bit of wire or something through the cam chain to stop it from falling into the tunnel

Thanks for all your help, team! I need to remove this chain as it's the only thing left that's holding the cylinder head down.
It's definitely spring loaded. I think I need to buy another tool for that!

And referring to the snapped off spark plug.. I'm going to machine it myself. I've drilled it out and will use a heli-coil or whatever to make a new thread.
I understand that I will have drilled a load of crap and filings into the engine.. but it's all going to be cleaned out anyway!
Things are starting to look a little positive!
(Jumping in at the deep end with this project! Now I understand why you all wished me luck!)

Also, my Haynes manual turned up today so I'd better get reading.
Thanks again!

No tool needed. Have a look in the manual and you will see how it comes apart. Simple case of removing camshaft and chain drops through tunnel

The manual's saying it's a standard spring clip that holds the link in place.. but that's not the case for me. (If only it were!)
Some blogs are saying I need to file the end of the rivet off to free it. Not too sure about that!

Trouble is, to remove the cylinder head, I NEED to unlink this chain! (Even to remove the sprocket!)
But not to worry. I'm sure I'll figure it out!
Thanks again!

Also.. Here she is, all stripped down and cleaned up!
index.php?t=getfile&id=21176&private=0

Baby steps!

Go to my post above and download the manual. Page 14 has a stepwise instruction on how to remove the cam without splitting the chain.

Hi everyone. I hope you all had a nice Christmas!

My buddy managed to get the engine apart, so I've spent some Christmas money on a new cylinder head and a cam chain with a PROPER split link! Cool
So it'll be a happy new year, indeed!
