[Manga]

Bike has been collected today with a list of defects - smoking from horizontal cylinder, clutch worn and noise from generator.

Roll on the return.

Hope they sort it for you
One point about the opening post, you refer to vertical and horizontal exhaust cans. On all the exhaust systems I have come across the intemediate pipe between the downpipes and the Silencers conatin a cross over that links the two pipes together, so that they are not independent of each other

Thanks for the help - wonder why the smoke only appears from one can then? Looking at the rear of the bike, it is the right hand pipe and the outlet is much sootier than the left.

If there is a link pipe then have you tried it with the can off to confirm which cylinder it is coming from. Great excuse to try it too. Had 3 and never had that problem.

Turns out the 'smoking' is unburnt fuel so all is good.

[skidlids]

And as the unburnt fuel isn't expanding like the hot exhaust gasses it tends to head straight down the pipe and out of the end can without expanding through the hole in the link pipe

unburnt fuel is ok? unburnt fuel = less power = less fun!
