I have posted on Chris's Rickman post, it was his generosity that pushed me to look for a bike of my own.
In the 70's and 80's I owned FHO45K, originally a 750 Commando, later converted to 850 with a great motor built by the late Fred Barlow of FBS spares Staffordshire.
I sold it in the early 90's as we had a house that needed new carpets :cry:

3 months ago I went to look at an 850Mk11a, fairly local to me. Was quite impressed, a top end rebuild helped matters and I decided I wanted the bike, against my instincts as I had not ridden it, turned up a couple of days later to collect with Dan, my son just to get his opinion.

The owner rode the bike down the lane, returned to find it popping and banging, took the points cover off to find oil in it, got the bike for quite a reduction in price as it stood.

Took the bike to France where we have a house, changed the oil seal, made no difference to running. Chris suggested a battery charge as the bike is fitted with Boyer ignition.

Now runs perfectly, ridden it 4 times now. Feels good, not as quick as I recall but that's not what I want it for. Not sure about the single 32mm Mk2 Amal conversion but it will stay at the moment.

Total cost to get it running £25 including new kick start and gear shift rubbers.

Glad to be back

Congrats on your new Norton. Bad running + easy fix = good karma. :wink:

Welcome back to Commandodoom. Do note if the Boyah trigger wires have not caught you out yet they will until upgraded with better wires and terminations. Btw oil does not affect boyah triggering nor regular points for some time till oil cooks up a crust. Might think about upgrading the crank ventilation to suck oil back in instead of out somewhere nasty. Btw the boyah curve is meant for less detonation tolerate Triumphs so takes some the response spunk out of Nortons and races modified them to get around that - until better ign curves came on line with other brands.

I think he means that eventually you will junk the Boyer Peter..... :wink:

I have a Maney Boyer with crank trigger, we will see how it goes...logic was it is simple to set up when starting out with the bike.....I may eventually look at a programmable system from Ignitech in the Czech Republic for about the same price....also crank triggered...

But there is more than enough talk on here of ignitions.....

Have you got a link to info on what shape the advance curve should be for various applications of a Commando motor ? I've always used fixed ignition advance and jetted to suit it. I believe there are two easy ways forward for me - programmable ignition advance is one, the other is by investigating the range of available tapers for the Mikuni needles that I use in my MK2 Amals.

Hobot, I got caught with my boyer sensor leads not being crimped properly, causing a broken wire. What is the mod that you do. So far I have only fitted new crimp terminal and re-crimped the ones that were not broken.

I got Greg Fauth's wire upgrade kit which has more finer flexable copper wires and uses posts and nuts to fasten to trigger plant and some nice skrink wrap back up. Don't double nut on back side of posts like I did against Greg's instruction sheet as caused serious coil triggering header glowing Loud back firing horror all those at '04 INOA Ohio rally will never forget. I found the Posi-lock small size fit under points cover so could undo w/o hurting wires to pass through cam cover when needed, ugh.
