Another interesting update, this morning i started the bike with absolutely no trouble whatsoever!
One blip of the throttle and it ticked over happily, no choke needed at all.
About 90 seconds later i was off down the road expecting it to get throaty again for the first mile or so......but.....
nothing!Smooth as you like, no issues at all as if i'd been riding it all day!
It's fairly mild outside but was foggy, but i'm starting to think the alcohol i put in the tank on Wednesday has done it's job and helped burn off any water that may have been in the tank?
As i said earlier i'll still drain the bowls in the morning just so i can say it's been done but at the moment it appears to be back to normal
