I am quite close to finishing the Navigator. I have wired it up and now need a battery. I have fitted a Boyer kit but not done the timing as yet. The handbook copy gives a figure of 24 degree BTDC. I am assuming it is just a matter of using a degree disc and lining up strews with holes ala all my other bikes.
Hello all--me again,
What is the story with the two breather pipes from the back of the oil tank? One is of a larger diameter than the other--one connects with the engine breather I am assuming--is it the larger one? Where does the other one go?
You won't have any real problems with timing. Use a degree disc as you say to get the engine running then experiment a bit with final timing. I know the info on the Navigator does say 24 degrees but this figure is a bit suspect and might have been a printing error; the Jubilee is 32 degrees and the Electra (I think) was quoted as 30. In practice I advance the Navigator timing to where the engine seems happiest; but don't overdo it.
The second pipe goes to the chaincase; a proper Norton chaincase has a hole in it at the front end for this very purpose- an FB chaincase looks otherwise identical but hasn't got the hole for the breather pipe. But it isn't critical where it goes.
I think I used a degree disc and lined it up with the screws initially to get it going then I used the disc with a strobe to set the timing accurately.
I did wonder about the 24 degrees as most British bikes are around 30 something. Ah--I see a chain oiler--I have one on one Triumph, not that it has ever worked. I do not as yet have a chaincase. Cheers
So the smaller pipe is the chain oiler?
All my machines at the moment are all covered up so I can't get to them easily. and I can't find my notes on the oil pipes. So from memory the standard oil tank has the two connections on the top/rear of the oil tank; the one slightly higher up and to the left hand rear is the one going to the chaincase. I thought the connectors were pretty much the same size. The De Luxe tank is completely different and has a long neck with a connection on it for the pipe to the chaincase.
You don't have to connect into the chaincase; you can loop it up somewhere neat and let it breathe to atmosphere. At least just for testing.
With regard to lightweight timing, you need a fixed pointer in the chaincase and of course a mark on the rotor to coinside (more crappulus spelling-no speely cheeker). I have drawn up a fixed pointer, this is on my web site aoservices.co.uk incase you have forgotten, click on the orange icon at the top and find the right pdf Norton lightweight Timing aid. MIght be some other info for lightweight there as well.
