Re: '72 Norton bogs down after less than 10 miles - need ide

Lots of good suggestions so far.
I'd take apart and clean the kill switch.
Maybe a poor connection that causes it to gradually overheat and open enough to run rough and once cool closes enough to act normal.

I don't know what a new coil costs, I expect not a sheep station, but one option for coil fault elimination is an inline coil tester. This is basically a HT lead connected to coil and plug with a plastic viewing tube that will show a streaming spark with a healthy coil. Checking the spark stream when your problem starts occurring will show a broken spark stream if it is the coil that's breaking down. Simple test to eliminate one component. Or just buy another coil and be done with it. You only have one coil to buy, not two. I guess if you had two your problem would be one cylinder only so easily resolved. Most unlikely two coils would chuck it simultaneously. But you don't have two. So why did I even say this?

Why do I say anything?
No one listens to me.
I want sympathy.
And $200 to give to Jerry.

PJ, I don't wish to sound negative or anything such, but, mechanical 'attention to detail' of that nature would make me want to go through the rest of the bike with a fine toothed comb!

Nevertheless, having said that, and I hasten to add that I am certainly NO coil expert, but the damage you show doesn't look significant to me, and IMHO isn't the root cause of your issues.

Eddie, mayby ,mayby not! My mates Rocket three started and ran great 12 months ago...it only stood and a coil went down! What the F*** happened to it? Never knew standing bugged coils :?: I hope he finds the reason and lets us now...Soon!!!!!

Well there's only ne way to find out John.. test it.

So come on PJ, stop messing about will you? We're all on the edge of our seats in anticipation here...!
 
Re: '72 Norton bogs down after less than 10 miles - need ide

Eddie - yes, I agree the coil mount wasn't the PO ' S best example of fabrication, but aside from that I have to say he did a pretty good job. I have to say I get the feeling this bike is going to going to need to be shown who's boss. Check out the latest- I put in the Power Arc all nice and neat and am just tightening up all the connections. It a beautiful day today and I can't wait to give her a test run to see if the issues have been resolved. I literally begin to tighten up the coil post nuts and.....well, you can see what happened!!!!!!! It had just begun to get snug - hadn't even starting applying any kind of torque. I was pretty ticked to say the least - but I have to give huge props to Fred at Old Britts (where I bought the EI system from). I sent him off an email, and within an hour he responded saying that he would send out another coil, and less than an hour after that email I got a notification that the part had been shipped. I've got my go to guys for Triumph parts, and based on Fred's response, it looks like I've found my Norton parts guy. It's becoming more rare these days to find a company that takes care of its customers, and fortunately Old Britts seems to do just that. So I hope the coil gets here Friday morning and I'm riding her before noon. Again, I'll keep you posted.

I've done business world wide to find most the big vintage vendors are very helpful for old parts, mods and new items. In the past a few installs of the PowerArch had a sloppy fit on cam shaft taper so a cone like adapter was made to keep the sparks stabler. Look in the Tech section photo instruction thread for a list of vendors worth supporting.

I think eddie you are referring to the dents in the coil yes?
Coil could be stuffed of course without external damage.
If it was me, I'd just buy a new coil and find out, real quick elimination one way or the other.

I might hold the record for most posts per time frame.
But your going to break the record for longest thread!
Some advice, give it a week then tell everyone the coil got lost in the mail.
This is going to be another Days Of Our Lives episode!

Re: '72 Norton bogs down after less than 10 miles - need ide

Phil - not to shabby, first thread and I'm heading for a record - I'll take it! I figure if you and the others on the forum are willing to take the time to offer your assistance, the least I can do is keep you abreast of what progress is being made to solve the issues. I hope this doesn't turn out to be a bestselling novel before we find the cure!

Of course we like to hear the progress PJ.
Folk in here are having sleepless nights wondering what the problem could be.
All I'm suggesting, if you want to hold this record forever, drip feed the info only.
Chinese torture style. Start talking about the paint job, then back to the problem.
That sort of thing.
It drives the masses into a frenzy!

Re: '72 Norton bogs down after less than 10 miles - need ide

We have liftoff! Got the new coil this afternoon, put it on, dialed it in and buttoned her back up. She fired up right away, and I took a very limited run (10 miles) with her because of angry weather heading my way. She ran and seemed to sound smoother than before, and after a few tweaks to the carb idles nicely. Of course, the true test will be when I have a chance to really take her for a good long ride to see if the issues have been resolved. Naturally, tomorrow's weather doesn't look very promising, so I'll be rebuilding a friends '69 Bonnie engine, but if there's an opening I'll put the spanners down and take it. Results of the long ride test will follow.

I'm claiming an early victory. pete.v said I had it all wrong.
Lucky for him he didn't put his money where his mouth was.

I reckon I could better that DogT, but unfortunately my topics get hijacked by an angry vigilanty team looking for justification, and the topic gets locked. I've had a few attempts at your record, no luck yet. I'll give it another run. I think at present my exit speed off the ramp needs to be a good deal faster. Might have better luck on the new hot MkIII.

Metrics and lesser Commandos will never catch me.

Re: '72 Norton bogs down after less than 10 miles - need ide

Well done PJ. Please keep in mind that the EI unit you have now has much less draw on the battery.

My thoughts on what the problem may have been is one of many. We need to be open minded and cover all the base.

Whether I am right or wrong means little, the big picture is getting another Norton get back on the road.

The best part is that you did it. When you go down the road knowing that is when you feel "real" Commando Character.


Not this cheap ass shit coming from the biggest wanna be I have ever heard of.
I am sorry but the cancer still grows.
The sad part is that he makes it about him and tries to steal the respect that you deserve, for these are the things that he would have others do. Others successes only serve to remind him of his short comings. Why do you think he writes so much. I t must be very painful and lonely for him.

There maybe many aspect to this so called Commando Character but there is one thing for sure PJ, You got it and this is YOUR thread. OUT!

Click to expand...

there is no "team" of forum members hijacking "your topics"

there is no conspiracy against you, Phil

what there are is a growing number of people who are tired of your compulsion to non stop post to every thread, to reply to every reply, your own hijacking of other people's threads ending up making them about you
and pubs and drinking, constantly crowing about how your Mark3 is just the best Commando, etc, etc, etc

by the way, the only person with authority to "lock a topic" is LES, and he stated only a couple of days ago that he will lock threads that turn into teenage personal social gushing and that have no Commando content

and make no mistake, you are the primary single reason for this yet is seems to go right over your head

Maybe you should spend more time on the unapproachable Commando than the keyboard.

I'll have to agree with others, I don't read Phil's posts much any more. Tends to be a wast of space on the forum to be blunt.

There's no glory in having the longest thread, just ask me, although the picture thread is longer. I think the Keith Headsteady did a long run too.

Once said is enough for me. Let's move on.

Re: '72 Norton bogs down after less than 10 miles - need ide

Nice one PJ, hopefully you can now enjoy.

I guess we'll never know if it was the coil or the ignition unit.

Actually I know it was the fuel taps... you fixed them in secret and aren't telling us!!
 
Re: '72 Norton bogs down after less than 10 miles - need ide

Eddie, No it was the bend in the fuel line that nips up [folds]when hot! He changed the pipe's shape with two 90 degree bends ... anyway
Glad he sorted it...now i have more brain space :lol:
