I went to see a mate today and whilst on the way I felt a little change in the way the Mighty Midget was running followed by a lot more backfiring on the overrun. Long story short for those who haven't guessed; silencer had cracked at the pipe joint, frame bracket for silencer had broken and pipe Y-piece had cracked through! Bugger.
On the bright side: with a bit of judicial wiring on the MM got me the 30 miles home ok, and it is an opportunity to convert it to two separate pipes with a silencer each. Might not be ideal, but at least the MM lives again! Hurrah.
Just out of interest what, if any, carb adjustments might be necessary going from a 2 into 1 to a 2 into 2? Judging by how it ran on the way home with everything broken and hanging off, not many. I already don't run an air filter so maybe it will all balance up? Any thoughts welcomed.
Spartacian the noisy.
