My bike cut out quite often when new...it got better after 300 miles...

It still cuts out occasionally now...on overrun....BUT i have modified some bits, and haven't got the fuelling perfect yet....

Remember tho, it is only a single cylinder, not a smooth as a four cylinder, so it will benefit from just trying to give it a few more revs when pulling away.

i think when you are de-cellerating, and it cuts out, it is a problem with the ECU, BUT A CURE FOR IT IS COMING SOON!!!
