Re: R50 rocker bearing shaft replacement

Thank you for taking a moment to reply, James! I plan to have a careful look at them today. I suppose checking for play is done exactly as in /5 machines. Is there a different type (not flat) of feeler gauge, or another method of measuring clearance between the shafts and rockers? Again I always app...

R50 rocker bearing shaft replacement

I have not done this before. Now that my heads are complete, as is my bottom end, I want to do what I can with the rockers prior to installation. Years ago I bought a set of NOS rocker bearing shafts. My shop advises that I dismantle the rocker assemblies and check for wear marks, etc. I have done a...

Re: Early R50 pushrod tubes

Salis does not even include pushrod tubes in this diagram. I first looked at Max BMW, because measurements are oiften shown, but had no such luck! I will try looking at the new Bench Mark Works catalogue to see if measurements are given.

Early R50 pushrod tubes

I have a set of used (slightly scored on the 'lip' side) which look ike they can be cleaned up and polished. I want to know the correct length for mine, as I may have the slightkly longer R60/2 ones.

This forum is a great go-to for info one cannot find in regular searches.

Re: Early R50 blade-type brake/clutch perches

Thank you Vech, James and Tommy!

I switched the levers around and everything fit just fine, just like you said, James!

What was thinking?

Re: Early R50 blade-type brake/clutch perches

Thank you Tommy and James! Regarding the fit of the handles to the perches: I tried each 'spear' on the other perch first. The clutch one has a much thicker mount, and will not go in the throttle side perch. Also the holes for the retaining screw do not line up. As for the throttle side, the contour...

Early R50 blade-type brake/clutch perches

I have an original set of Magura clutch/brake levers that I thought would work with my perches. Today I tried putting them in place. Obviously my perches are incorrect (see attached photos). Can anyone help me end up with the correct perches without having to pay 'an arm and a leg?' This is the best...
