Its been a while, but everything has been going so well. And now as usual I'm here when I need help.
During a great enthusiastic ride on Sunday over the Helmsley TT the bike running crisp and well.
Refuelled at Malton with Excellium (best I could find) within 10 miles bike occasionally had a power delay on opening throttle around 9k then after a change down we were off (mostly).
Did this quite a few times and seemed to be worse after a few moment on a closed throttle (for example coming upon a line of cars prior to overtake)
Called in at Sherburn and then noticed very rough running and it stopped, refusing to Idle and would not start. Had to drag the wife out with my van and rewinding my day put everything down to some crap in the fuelling.
Anyway carbs out and tank emptied plugs checked and found nothing, all seems well.
It will kick over and reluctantly start with the top cylinder running well. Getting PHUTT type backfires from the front cylinder and it will not idle. Front cylinder runs fine above 5k but seems to be nothing below but occasional backfires.
Done search for backfires on this site and now think I may have an electrical issue that developed on my ride.
I'm ashamed to say I haven't layed a spanner on it for 2 years, just ridden it.
