Re: Fitting Allen screws to rocker box on B50.

If it is the same as a B44 then you only need to use a couple of Allen screws at the right rear, it is these two studs that prevent the rocker box being removed. The rest of of them can stay the same so the issue of the head steady fix doesn't arise. In aluminium I would use UNC which is what the th...

Re: B25T Rear Chain Oiler – Cap Off?

When you blank off the hole just make sure the screw doesn't protrude too far and foul the outer chaincase gasket surface and thus prevent it sitting properly - it will leak like hell if it doesn't! Loctite the bolt in place and forget it.

Re: B44 Inner Timing Cover Damage and Differences

There is another difference too with apparently suitable cases. The B44 crank nose is slightly shorter than a B25 one, so a B25 cover (with the circlip retaining the oil seal) will not do , as the b44 crank won't quite reach the oil seal...not good!

Re: WM3 19" Front Rim?

I think it will depend entirely on tyre choice. Road tyres? If so select your tyre and look up the manufacturers sizes to see how big it is when fitted. With a WM3 on the front you might find the steering is a bit slower

I have a WM2 on my B44VS with a chunky trials tyre and no issues there at all
