Re: coils & condencers

John, I have always used NGK C8E or CR8E both work OK for me, the left hand rotor occasionally oils up, the last time it happened was queuing to join the Newcastle to Ijmuiden ferry, I limped on with quite a few back fires and just one rotor amazingly it got us up the ramp onto the mezzanine deck wi...

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...

Re: Carb adjustment

Mick,

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"

Google "General charging information for AGM and GEL batteries" in doing so you will find all the information you need regarding charging and general care and maintenance.

Re: more amps

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. I test my charging system as follows: With a good volt meter/multi me...

Re: rotation

John, I see what you mean.
