I assumed you had removed the sleeve. This should drive straight out either way. They can seize if not greased up. Again heat should assist if it is seized. You need to make sure the bush is against something solid but not blocking the end of the sleeve then drive it through from the other end.

I assume you have tried heating the swinging arm? If they are that stuck I would suggest to cut a slot across the end with a hacksaw. Then carefully extend the slot inside as far as you can with a hacksaw blade and a dremel. This will weaken the pressure off the bush and allow to to knock them out.

The details of primary chain wear are in the manual. When installed there should be no more than 32mm play. You need to inspect the upper and lower chain guides for wear and function. One of those is spring loaded at that one has been known to fail.

New Primary chains are almost none existent so if yours has gone replacement I could only help…[Read more]

Cheers for letting me know Jon

Are these for a B2? I have found the B1 stripes at Diablo but they work out quite expensive. There is a place down Leicester way if I remember correctly. They said they will do them but they need samples to copy. I haven’t had the chance to follow this up yet.

Whereabouts are you?

Is that one of the front middle two? They are open to the elements and always cause problems for removing the barrels. I would seriously look at replacing those 2 at least as that is where the head gasket usually fails.

That is bad. I also notice it has a copper washer. That should be an O ring. Will add that too.

Yes I will also add a front tensioner and PM you with details again.

Hi Karl

I have gone through your list and can so far supply everything you asked for. I have added an oil filter and oil filter O ring plus the 2 seals in the sprocket housing for the gear selector shaft.

Most parts I have here but some I will need to order in.

The total cost for everything (inc extra bits suggested) is £237. I am guessing…[Read more]

Do you mean the O ring one shaped like a No 8?

Hi Karl

Please see below

Full gasket set – I only have top end gasket sets at the moment. They covering everything from the large ‘O’ ring on the bottom of the barrels up except for the valve guide seals. I have got Clutch cover, Points cover, Generator cover, Transmission cover, Clutch adjuster cover and Oil pump gaskets separately and can add…[Read more]

It’s amazing what a wash can do. Still a lot of work to be done though.

Spoke to Phil at Zpower and he doesn’t think he has the valves but will check Monday and let me know. If you’ve seen valves I’m guessing the will be for a 4 pot but’s let’s see.

If you send me a definitive list of what you want I will put a price together. I definitely have…[Read more]

Hi Rob

They don’t need the rings. Another option you have is a firm in Manchester called NRP. You send them your slides and they fit the diaphrams for you. It does cost more, think it’s around £45 each.

Like the picture. What’s it like riding with those tyres on?

I’ve sent a PM about the rubbers.

Cheers

My God Karl you’ve got your work cut out with that one but full respect for taking it on. Think I remember seeing it on ebay? For your information the engine is a 1976/1977 B1 or B2.

If I have read your post right you have managed to get all you need except for rings. That I am impressed with but I am surprised you say Zpower have valves. I am…[Read more]

Hi Rob

These are the diaphrams you need Diaphrams

I have some good used carb to head rubbers if you are interested. I can also supply NEW airbox to carb rubbers if you need those too.

Cheers

Hi Rob great to have you on board.

It’s good to see your getting use of your twin and now making her better than she was. Hopefully this site can help you get there.

Please check out the shop for any parts you need. The stock shown is by far not everything I can supply so if you don’t see it please just ask.

Would be nice to see some pictures…[Read more]

Blimey Karl that is a very sorry state engine.

As you suggest much of it is recoverable but it raises suspicion with the whole motor. The sludge is definitely a mixture of oil and water and the main question is what other bits has it damaged. Looking at the oil filter gauze there appear to be shards of metal which you need to determine where they…[Read more]

Hi Karl and welcome to the forum.

I have moved your post to the forum so people can see it. The forum is the place for these discussions.

The situation you describe are not any normal thing I have ever come across and I think you are lucky if there is no permanent damage done to the engine. You should NOT run the engine without fitting the…[Read more]
