Evening James,
Thanks a lot for your explanation.
My problem is that from the beginning I could not insert this rubber sleeve inside the headlamp's bracket hole.
Understood, I second the "rubber hose" idea! :D :D

Re: Where to locate all the rubber parts of the headlight support brackets?

I second the rubber hose! What I do is the following: 1) I put the "tube" #17 through the headlight mounting ear without an 8mm bolt in it. I have had a few that I needed to use WD40 on to get it through the headlight mounting ear. 2) I then put the two flat rubbers #16 and #18 over top of the #17 "...

Dumb question... Are you sure the gas cap is venting? ....
That is NOT a dumb question. Fuel flow is a possible cause, either non-venting cap or clogged filters, but I am fairly sure he checked the filters already.

Re: '63 r60 losing power after warmed up

I am going to take the advance off tomorrow and inspect. While it is still on the bike are there any simple diagnostics I could do to determine its general condition? And, once off, will overly worn lobes be obvious? The way that I found to be the best to check it is as follows: 1) take the condens...

Re: '63 r60 losing power after warmed up

New to forum. Power loss consistent after bike warms up - 12 to 15 miles of riding. Recently cleaned magneto, installed new coil, points, condenser (from Vech, who has been great.) Properly set gaps, timed ignition. Also changed rings on one cylinder with low compression. New plugs, good spark. Sta...

Re: '63 r60 losing power after warmed up

Losing power like stalls and dies or keeps running? Good carb gaskets at the head and the bolts holding the carbs to the head are tight? Warped carb flanges? Chrishea, typically warped flanges would make for a high idle when warm because it would be sucking air in the flange. I have had this proble...

Would a dirty petcock filter cause power loss after 10 miles? Will definitely check.
Yes, it would.

Re: '63 r60 losing power after warmed up

Do you have fuel filters in the fuel lines? If so get rid of them and retest.

Could also be dirty filter in the petcock. Anything slowing fuel flow.

Re: Correct routing of the N indication wire from the tranny?

Micha, After I sent those I remembered that you had an R51/3 that was a few serial numbers away from mine and that you might have been talking about that one. I went down and took pictures of that one as well. I cannot vouch if this was the way the factory did it because the harness was changed at s...
