1974 Norton Commando 850 - Part 11 - timing check and carb sync 

He sure is 😁 😁

Many thanks, Martin! 👍

Hi Malcolm, apologies for the delay. The orange commando has a cheap battery in it that I would like to replace some time. This is the one that I have in the black commando and have been really happy with it. www.batterystuff.com/powersports-batteries/sYTX14AHL-BS.html Best wishes, Mike

@@TheMightyGarage thank you Mike, Im looking to 'upgrade my battery given the CNW electric start system albeit my Commando now starts very quickly and has the 3 phase alternator and modern rectifier/regulator etc.

😁😁! So true!

Yeah, looked awful cramped in there . Still , I suppose you've got to work with what you've got .

😁😁

Yes, thats why the JPN racers received flexible mountings, now THATS irony.

Well spotted Kevin, yes it's a 1952 AJS 18S. It's in a bit of a state and Geoff intentionally bought it as a long term project intended to slow himself down, otherwise it would be running by the weekend 😉

Yay! Got one! I'd love to see it when it's eventually done and off the lift. I'd say a video is in order in time. The American market longhorn handlebars intrigue me.

@@kevindaly5093 yes I will definitely take a vid. I’ve got a few clips already from when he bought it as a basket case. Cheers

Hi Simon, no problem at all. Yes, I'm sure that you can use a normal strobe from the store and it works just fine on our positive earth bikes. That's what we were using at Geoffs and I'm pretty sure that mine is also a regular gun/light from an auto-parts store. Geoff also hooks his up to the bike's battery, although I understand that some guys may prefer to use a separate battery if possible (to reduce electrical interference). Once you have set the timing or want to check your existing timing, you start the bike up and then rev it up to the desired RPM (revs can vary depending upon the ignition system you have and you can also check at different revs - for example at 3,000 or 5,000). Then point the strobe gun at the stator, which should have 3 slots/lines/grooves. When the bike is revving at the desired RPM, the big groove one in the middle should line up with the 29° mark on the indicator plate that is attached to the inside of the cover. If it's out of timing, then you can adjust the points or electronic ignition and then repeat until your timing is closer. Here's one of many articles on the AccessNorton forum. I hope this helps. Cheers, Mike www.accessnorton.com/NortonCommando/timing-mark-confirmation.6145/

I am using the tri-spark the same as you so that makes the job 100% easy for me cheers for your help

@@simonwootton-davies1179 No problemo. Good luck Simon. Cheers, Mike
