Navigator side stand?

Submitted by nicholas_clarke on Wed, 03/06/2020

I am thinking of fitting one of the side stands advertised in the NOC shop to my Navigator.  However, from experience on other bikes I have a healthy suspicion of how secure bolt on stands are, how well they hold the bike up, whether they foul the exhaust etc, are obtrusive when folded up and limit ground clearance in left hand corners.   Finally is the NOC side stand value for money?   Any feed back form those who have fitted them / owned a Lightweight with one fitted would be gratefully received!   Cheers  Nick        

Jubilee engine parts

HI, picked up a jubilee in boxes at the weekend and i am trying to workout what is missing for the engine. I have assembled the engine to what i can see and make out in the manual but missing a few components for gearbox(later type). In the photos i have attached below,  image 1594, is that the index plunger for gear box (item number 24 in parts list) and that i am missing the parts marked with the red arrows.  image 1597 what is this part?

image 1593 shows where i have set the timing does this look correct?

Jubilee Strange Markings

Hi All - before “boxing up” the engine I noticed a “strange” stamping on the cylinder barrels.  There’s a “B” on the outer surface of both and a * on the front of only one cylinder (LH - see photo).  I thought these might have been identifying the pistons for correct clearance (they were originally rebored to +40 when I bought my box of bits) but there’s no corresponding marks on either piston.

Anyone got a idea what they’re for please?

Bruce

 

What is this part?

In my parts book (64 on Jubilee & Navigator) it lists a “Spray Baffle” part # 23652.  Part doesn’t seem to exist anywhere nor pictures of it.  Anyone got an idea what it is (& for) please - also, is it for the later Jubilee?  Picture of mine as it is right now - not far to go (hopefully)! Thanks - Bruce

Hello, my dad gave me this bike about 20 years ago and it was in pretty good running condition. I recently moved and exhumed it from the damp shed where it sat for 20 years gently rusting. I would like to find someone who could strip and check the engine before rebuilding it and upgrading the starter. I will do the other cosmetic work myself. Any suggestions gratefully received. Thanks

Good news and bad news:

Good: I found the reason for the leaking gearbox on my Navigator: the bottom screws were too long and bottomed out withouth tightening the gearbox cover. Shorter screws solved the problem.

Bad News: Another seized piston! This time the left one. I was doing 60mph when the engine sounded stressed and I pulled the clutch.

hi , I'm having trouble getting a early type sprocket nut 041271  for my  navigator , they are not listed in noc  so ordered one from rgm but its the right part number but it's too large so must be for the later type . does anybody know the size or if a nut from another machine will fit .
