I checked a few times for leakage at carb bowls, connection lines and all around under tank. No signs of liquid or residue with any smell to it, just the normal layer of oiliness.Is it possibly dripping from the bottom of one of the carbs? I have had two experiences with this.….float bowl screw fell off and tickler stuck open.
Hot weather and gas cap venting?Last little while been getting a whiff of petrol when idling at stop lights etc. Was thinking from surrounding cars but now think it's my bike. Seems mostly from left silencer end. All seems to be running well. Normal or adjustments needed?
Possibly. Not that hot here yet, 22 C or so.Hot weather and gas cap venting?
Yes could be. Had that happen some time ago on original amals, symptom was misfiring under open throttle, gradually getting more frequent over a few weeks. This seems different but may just be starting to happen. Will tear into carbs soon.One more thought…left carb main jet block unscrewing. This has happened on various Commandos more than once on club rides.
