The way my Flash exhausts are so not evenly spaced when viewed from the rear, this is due to two factors
1. looking from the rear the left hand silencer is too close, this due to having to tuck it in to avoid the kick start, problem is with the kicksart lever , it's a pattern one with the crank in the wrong place, a better one would cost me £50 or more though - still if it annoys me enough I might go that way ( I'm not that easily annoyed though)
2, the right hand pipe is miles out the other way due to having to avoid the footrest. however there is some hope for a cure, my friend was here today and said he had cured his by putting a spacer in between the front exhaust pipe bracket and the boss on the frame front down tube, this forces the rear of the silencer in towards the wheel.
Will try this tomorrow.
Got the Flash out on the road yesterday after retiming the magneto, think it must have been out a bit previously as it went so well.
Also think carb might be set a bit rich for starting as it seems to start better without choke, although it has been quite warm here of late.
One or two things to do before it's MOT, but it's looking good despite some of the paintwork crazing.
All the best - Bill
