Exhaust fitting

Bike has failed MOT - all with things that were exactly the same last MOT ? For instance light is European and kicks up to the offside. The exhaust is blowing where the cross pipe meets the left hand side - this due to a slash in the side of the crosspiece - to help with fitting I presume. I cannot move the cross pipe to get the slash to completely go over the s tub on the main pipe as it seems welded solid to the other side - one solution that is possible is can the exhaust mounts be a attached on the inside of the frame loop on one side to push the exhaust further across or will this interfere with the action of t he swing arm?

Mounting plates inside, outside, even one side inside and one side outside. I've seen them all to make an exhaust fit!
The silencers are going to make a lot of the difference for clearance.
Can you position one of the balance pipe clamps to cover the slot?

My MOT man says a European right dipping light is ok as long as there is blanking piece on the headlight lens to prevent the light actually pointing that way.
Unless, of course, the rules have changed?

As Paul said you could get a wide clamp to cover the gap. Also worth finding an MOT shop that is used to working with older bikes, some are only used to working with modern stuff, there are various rules that don't apply to pre 86 (I think!) bikes but some places don't take them into account, although the light isn't one of them but blanking will do the trick. I use Maitland Racing who also do restorations on 70s/80s Jap bikes and are sympathetic to the rules for older bikes, are real bikers and will suggest what needs looking at.
I'm sure with a few tweaks you should be fine.

With the exhaust mounted on the inside of the hanger on the near side it just about covers the gap - can't move the other side as the exhaust interferes with the wheel spindle. - a clamp won't do the job as it is elevated above the gap by the balance pipe and the slit then allows the air to escape sideways. I'm sure i have managed to set them up before without this issue - nevermind a new set of down pipes will be on the list to buy at some stage but despite looking rusty/tatty and a bit mangled by previous owners the current set refuse to die and just about fulfill their purpose. Took it back after blanking the light and a few other small jobs and it passed fine - same firm have mot'd it the past 4 years with no issues and to be honest we are not exactly spoilt for choice out here in west Cumbria - thanks Duncan
