New to me CB750K4

(1/4) > >>

ColinHH:
Finally picked up my '74 K4 after it had been in storage in UK for 6 months after buying it in January. Now got it back to France and am tinkering with it. It's in immaculate condition so not much to do but have done valve clearances, timing and points, as well as a good clean and polish. Carbs cleaning is my next job. The thing I am really struggling with, is getting onto the centre stand! I also have a BMW1200GSA which is 260Kg wet and I. can get that onto the stand without any problems. Same with my '78 BMW R100. Technique for both of those is to stand on the centre stand tang and the bike is almost lifted onto the stand with very little need to apply any other effort. The stand acts as a lever. Standing on the K4 side stand doesn't seem to do anything and I have to lift and pull with all of my might to lift it onto the stand. I can't keep doing this as I will do my back in at some stage. I am putting a piece of wood under the rear wheel to make it easier but wonder if there is a problem with the centre stand lever? Anybody else experienced this and have a solution?

Not directly related as it was a Yamaha but that's why I parted with my XJ900F it was just too much of a pull to get it onto the centre stand after 14 years of ownership.
In my case it was a combination of old age plus I think newer bikes have set the fulcrum point better so they are easier to pull onto the centre stand.

In your case it might be the stand pivot points are semi-seized and in need of TLC.

I have no problems when lifting my 750K2, in fact it's easier than lifting my lighter 500K2. The 500 has a 4.00 section rear tyre instead of 3.50 and so this may alter the starting angle of the stand (as wheel just touches ground while on the main stand). Not sure if this is due entirely to the larger tyre or a combination of the tyre and some stand distortion. (Has new pivot tube and no apparent wear on the stand female pivot).
Has your bike got oversize tyre (and touching ground as per mine)
Just a thought, otherwise can only be pivot seizure or stand distortion

On my 750F1, I have to perform a sort of scissors move, push down on the stand and lift at the side, this works rather than lugging on the bars.

Cheers

Worth measuring the length of the rear shocks or showing us a pic - I've had issues with (shorter) aftermarket rear shocks making the center stand much more difficult to operate. Also look at tyre sizes.
