Thanks again James!

Ken Cruise

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...

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...

I got the info from one of the /2 facebook group members: Ivar Westad:

Pushrod tubes R51/3. R50/2 R50S

Stainless steel, chamfered on Cylinder side
L: 94mm total
L1: 10mm from bottom tube to collar
D= 15.9 - 16.0 mm
D1: 23mm (collar)

Regards,

Ken Cruise

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.

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.

Thank you Vech, James and Tommy!

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

What was thinking?

Vech, I deeply appreciate your reply to my post!

I will print it off and go to my shop to do comparisons.

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...

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...
