Re: I need help

Graham,

I might be able to help. As I'm going to be visiting your shop on Tuesday for some rotary spares and if you happen to be around perhaps we could discuss this then in a bit more detail?

Re: Isle of Man TT 2020 with Rotary

Holger, I attend the IoM TT every other year always riding my Commander and have yet to see another Norton Rotary during my stay on the island, it would be good though to meet up with other Rotarian's. Riding a rotary provides the opportunity to meet lots of people not just from the UK but overseas,...

John,

I would like to attend but Devon is such a long way from Aberdeen for a one off event, I am going to be down south 12th May on my way to Portugal, so I could swing by?

Re: Commander rear brake disc

Paul, I fitted a new rear disc to my Commander some time ago, see attached photo of the box the new disc came in and the disc as currently fitted. I cover many thousands of miles, usually two up, on my Commander with no issues with the rear brake, FYI I use sintered pads. The Yamaha XJ900F OEM parts...

Re: spark plugs

John,

"Cold running" I don't think applies to my old girl,she runs at just under 100c

There is a difference between cooling water temperature and exhaust gas temperature, anyway let us know how you get on with the new plugs.

Re: spark plugs

John, I use NGK C8E and CR8E My Commander NS (left hand side) plug oils up if I'm stuck in slow moving traffic for a long time, reason is that the NS side sucks oil from the plenum chamber and the centre plate, when running at normal speeds I do not have a problem with plugs.

Re: Boyer ignition

David,

I agree, however I feel the Boyer gives a more even tick over, I have been told that the Boyer and Mini Mag use a different retard setting, that said the Mini Mag is good system.

All I have to do now is save up for a new one to carry as a spare.

Re: Commander will not idle when hot

Dean, If you do not have a manual let me know, if you do; follow the instructions for setting the idle. Air leaks between carbs and engine result in uncontrollable high idle, leaking cold start enrichment O Rings cause a very rich mixture. The SU carbs are a simple device but can cause issues if you...

I do not have any experience with the air cooled classics, just the water cooled Commanders, you should try to contact to Richard Negus.

Re: Carb adjustment

Mick,

High idle speed for me has always been due to air leaks between the card(s) and the rotor housings, any leaks here will increase speed.

Should read "the CARBS(s) and the rotor housings"

Zed, JB is correct in that your idle speed is a bit on the low side, 13 volts at motorway speed is OK. If you do not want to increase your idle speed its OK but I would suggest it is not a good idea to leave it idling for to long.
