I do not understand how to remove the rotor

My feelings weren't hurt, and there are different views from different people how to do things.
One isn't always better or worse then another one. You asked for help, got a few methods, picked the method that suits you best, and the next thing is believing that's the right way because Steve says so ?

I learned a lot in the past, one thing I learned that using brute forces / impact destroys things in the long run.

Did you noticed that Steve has to rebuild his engine because it's making more and more noise ?
That this happened while he was riding on it and did the maintenance? Did you noticed his rear tire (thanks davo) ?

Do you own a classic bike ? and did you put many miles on it ? enough to see how good you restored it ? (or not). Not many people here on the forum do restore a bike and ride it long distances.

I only take these people serious and listen very careful when they say something, because these people know, the rest has to be proven yet,

Oi, mush! Why have you singled me out? ☺

My motor's covered about 33,000 miles (x1.61 for km); the little ends have been rattling since purchase of this particular project; and it drops oil like an old Triumph. And the crankcases need stripping back -- they've been painted in the past; and the side casings need painting -- they're naked! And it's all part of the fun plan.

You're glazing over!

Correct me if I'm wrong, but weren't you the one who did rebuild the charing system with modern components ? Remember the test I did measuring the relative magnetic strength from different rotor's I had ? And that the new ones are always have a stronger magnetic field ?

Is this caused by a combination of heat and the impact of the engine on the rotor itself ?(according to Bill Silver), or is this because many people give it a blow with a hammer ? (or a mix of both).

Since the temperature of the magnets in the rotor not likely hit the curie point, it is said that the influence of heat is questioned by me. (please read this: http://en.wikipedia.org/wiki/Curie_temperature)

The magnetic field strength of a given magnet isn't chancing due to time that fast, but from influences from outside mostly.

So, what was the question ?

Hi Steve,

The experience of one man only doesn't make it necessarily the truth or right.
Any wise words on the magnets loosing their magnetic field other then to heat ?

btw, small ends always have a little play, the trick is to keep it as small as possible.

I seem to recall, from my GCE physics, that magnets can become demagnetized by hammering or dropping them when the poles of the magnet are at a certain, distinct attitude to the earth's polar regions. I've had my rotor off at least a dozen times in the past two years; each time (apart from the first, when the bolt was so tight and I was forced to develop my patented 'roll it off the centrestand' method -- don't try this at home, kids!) I've 'palmed-smacked' the spaniard to undo the bolt and used my own, home-made, low-impact rotor removal tool. And I really don't hit it with a hammer, J-man. I just call it nasty names in a stern voice; that's as violent as my method gets.... Really. No, really. Honestly. Yes, honestly.

Mine sound like they have a teensy-weensy little more than I'd mike them to! Akin to a worn Black & Decker percussion hammer drill!

Hi Steve,

Another 3 pages to go before this thread brakes the record of the thread about the question of what oil can I use ?

btw, what oil did you use to make that small end noise a little louder ? (Just kidding),

Sorry, 'like', not 'mike' Need new specs!
