Hi Paul, Which ignition unit to you have ? The original Boyer unit on my Commander was prone to behaving like this, something I put down to the retard thermistor (mounted by the water temp sensor) cooling sufficiently to advance the ignition.The Norton motors digital unit, on some, but not all machi...

Thank you for the replies, Richard and Graham, I'll give you a ring Monday Graham. My plan is to build a comfortable Bonneville, with the brilliant Norton chaincase by the way. Should keep me out of mischief!Regards,Howell

Hello, I am after one for my current project. If you can help, please send price details etc.Regards,Howell

Hi Mick, 0.01 or 0.03 mA is so small a current, it may be discounted, I would not class this as a dischrgrge.If your battery is 14 Amp/hours, it would take 14/0.00003 hours to discharge - 466,000 hours!

Hi Mick,The test you have performed appears to show minimal drain when the bike is stopped. If you set your multimeter to "DC Volts", 20, and start the bike you should show between 13.5 to 14.5 Volts if you connect across the battery terminals. This shows if you are indeed charging the bat...

Hi Gripper,Could it be too rich, due to the cold start "O" rings leaking?Regards,Howell

Hi everybody,Joe, is it upside down then? oh dear! Actually, if anyone would like to help regenerate industry in the valleys, these can be had from www.weekswork.co.uk, in Brynmenyn S. Wales for a very reasonable price in the colour of your choice! ( no commission I promise) Well. Joe and John, I ha...

Thanks Richard,I have ordered both halves plus terminals, and would have had to change the instrument cluster half as well (as a last resort) - if you hadn't helped me out.Regards,Howell

No problem Joe, I think my problem is solved thanks to Richard. Thank you once again. I have attached a scanned image of a Rotary decal that may be useful to other members.Regards,Howell

Richard, Yes Please! It would really save the day. I just need the red one - Thanks very much indeed.Regards,Howell

Oh B*****! If you are having trouble sourcing these Richard, then this could be tricky. I thought the connectors currently on VWP's site look different. The femail terminals shown are only 2mm diam, as well Joe. I have ordered a couple of connectors with terminals to see if it will do the job if all...

Thanks for the info John, I will check these out and let you know if they are the same.Regards,Howell

Help! Does anyone have a 9 pin connector plug which connects the harness to the instrument cluster? (Femail sockets, the harness part.) I am one short of completing a re-wire, and would prefer a red one, but a white one will do. I would be very grateful to find one. Please contact me with price &...

Hello all,Thanks to Trevor and Evonne, and Joe for their kind comments regarding the Welsh contingent's efforts. It was a pleasure meeting up with such interesting, and good people, and to offer help when needed. The event was very well organised, and the whole trip a great experience. (The M25 comi...

Hi Joe,Myself and two other Norton owners from South Wales are going,That is : Howell Evans, Roger Needs, Brian Wetherill. We have booked into the Hotel Aquqmarin in Lubeck from Thursday 30th to Monday 3rd. Please advise of any costs incurred in attending, and we will be happy to oblige. We are look...

Happy New Year to all.Hi Richard,I think I had the last one of Andover Norton's stock, and was able to get a good used one from Graham at Startright's to make a pair. I am looking for a Classic aircleaner Right Hand cover if anyone has one.Regards,Howell

Thanks Richard, very interesting. One for the future I think. I look forward to the finished job.Ian, please see attached photos 001.JPG 002.JPG Richard had a big part in this, as he put one on the "Jam Sandwich", my solution though was to keep the stock alternator and modify the pump hous...

Richard,The thing is, the bloody thing can fail in different ways. The Regulating thyristors precede the rectifying stage, so overvoltage is just as likely as under voltage.The Commando used a Zener diode as a current dump AFTER the rectifier, (Even cruder) but often failed short circuit, so took th...

Pleased to help if I can. gripper, repairing a 20+ year old PCB is fraught with issues - throw it in the bin! It seems that Reg. failure is common in the motorcycle world, and has caused a lot of bad press for some time. (bearing in mind the potential for actually causing failure by jump starting et...

Hi Richard,No doubt you have experienced far more of these problems than I have, and I wouldn't contradict anything you have to say on any rotary related matter of course. However in 1996, my Interpol showed the same symptoms and was cured by replacing the, by then, toasted sparkright unit with a Bo...

Sorry, I should have said never jump start from a car.

The trouble is that most motorcycles have a permanent magnet alternator, and these are regulated by shorting thestator coils using thyristors controlled by output voltage. This is why the heat sinks are necessary. Good advice also, is never to jump start, or use a booster with such a system, as too ...

On the Interpol, the revcounter takes a pulse from one phase of the alternator - check for a good connection here,(a yellow wire I think) and check battery voltage with the bike running as this could also indicate a failing regulator.

I may be wrong, but this sounds like the cold start device "O" rings have perished. I would remove the carbs and check.

Morning all,I have collected a lot of stuff over the years that may be of use to somebody:Interpol 2 fairing, lowers & headlight frame.Interpol 2 single seat and glassfibre baseP52 Commander rear end, comprising seat, panniers and centre section, "boot lid" & frameSparkright igniti...

Hello,I have found some good quality stainless fasteners on the "Bike Devils" site, made by Pro-Bolt. They are not direct replacements however, as they require the original receptor plates to be replaced by riveted on ones. Judicious filing of the mounting plates at the rear, and the glass...

Hi Johny,It does seem that the 'box is not the best loved part of these machines! I have to say the front forks are not a patch on the IP2's either. My Commander is clunky as well as noisy. But- an old Brit bike that needs minimal maintenance and goes like hell, as well as being comfortable make it ...

Thanks JB,Looking forward to the Cruise!Howell

Hello,I thought I would share my experience of these clutch mechanisms/dragging/poor neutral selection.My Commander was awful in this respect, much worse than my interpol. I decided that the dog-leg lever was constraining lift, so I have fitted an interpol lever which imrproved the situation greatly...

Thanks Roger and Mr. Mod.Yes, my Commander also has a noisy 'box, but the interpol isn't bad by comparison. The stripdown and inspection will hopefully reveal the problem.The Santander ferry to the NOC anyone? See you there.Regards,Howell
