Pazon timing

Find TDC, turn engine back to 24 BTDC, turn the Pazon cct board until the LED just comes on, then turn the board back until it just goes out. Job done.

I marked my rotor for TDC only. I cut a hole in the primary chaincase and marked that for (in my case, 650SS) TDC and also 28 BTDC to allow checking with a strobe. Hole is then plugged with a large grommet.

Good luck.

John, The ignition timing on the Jubilee is 32 BTDC not 24, Attached page from manual.

Thanks Kevin.

I dont think there is a LED on mine. Its a (product code) PA2L

Thanks

Ah, sorry about that! Mine is the PDMT1 SmartFire. I think the principle will be similar though.

When setting the timing, isn't it regarded as good practice to turn the engine back beyond the 24 (or 32) mark, then move it forward to the chosen mark so as to take up any slop in the gears?

Yes. I was always taught to do this on BMC A and B series engines. But these engines do have timing chains.

Could I suggest to John that he read the instructions from Pazon- if you set the timing to 32 degrees static does the Pazon then some how automatically retard the timing for starting ?. 32 degrees is full advance and too much advance could wreck an engine. Sounds odd to me but I am not familiar with aftermarket electronic ignitions.

Hi Patrick,

Yes, you do time the Pazon at fully advanced. This is when the LED comes on. When running, it sorts itself out.

Thanks Tony for that confirmation.

I looked up the Pazon website last night and I was genuinely impressed with the detailed technical information that it supplied. There is even a graph showing the spark advance which unquestionably shows that it does retard the timing for starting/slow running and advances the timing as required for higher engine speeds. It also gives some useful information on coils to use. All told the website does gave the impression of a well designed/researched quality item; quite surprising in fact for such a low volume machine.

Their website gives the same timing for the Jubilee/ Navigator/Electra -all at 32 degrees-which does make sense to me even though most traditional sources seem to quote 24 for the Navigator.

If you follow this website timing for the navigator as 32degrees and at a later date damage occurs, who you going to blame? I have set the timing on my navigator at 24` and tweeked it a little bit nudging up slightly the advance. I have recently been on a long sustained run up to speed limit (occassionally),no problem. On the way back (after150miles) I topped the tank with 10 ltrs of 98 unleaded from a supermarket service station and continued my journey,the bike then started to struggle.I got back and flushed my tank with the fuel I was using usually, and everything went fine again. My point is ,even if you set your timing to original manufactorers reccommendations modern fuels and inconsistances have an effect on ignition timing and I thought all fuels were the same??
