i was riding my yb100 saw a ferrari and knocked it down a gear instead of up it made a horrible noise and started backfiring and lagging cant think of any word to describe it when i am going along it pulls back for less than a second the stops for another half sec then does it again.

left it for a bit not backfiring but at 40ish the bike does the lagging thing just wondered if you knew what it could be maybe

thanks webi

edit: i can actually physically feel it pulling back is this misfiring?

You should only use a Rizla for setting the "breaking" of the points !! Preferably a "blue" rizla paper as they are the thinest

Set the "gap" to the recommended setting with feeler gauges.

(the "old school" trick here was to use a "cigarette packet" to set the gap, same with the spark plug)

Good luck

Damn! a cigarette packet, thats one huge gap for a plug

OK, smart arse

Maybe I should have been a bit more specific

THE CARDBOARD FROM A CIGARETTE PACKET, which was about 15 thou

(Park Drive/Senior Service etc.)

Which should give a large enough gap to allow a spark to be generated,

THERE IS NO RELIABLE SUBSTITUTE FOR THE MANUFACTURERS RECOMMENDED SETTINGS, however as a "get you home" bodge, the aforementioned method will "usually" suffice

By the way, shouldn't this be in the "Workshop" forum

right guys thanks for your replies set the plug gap with feeler gauges was 0.014 inch i think but earlier i was going along it backfired (sounded like it was spitting from the exhaust a sort of splutter i guess) and died had to run and bump it 3 times to get it to clear think it flooded it then also did it when entering my village but didnt bog down and flood

i think it is flooding anyway not really sure what started this was i was doing 25-30 and instead of going into 3rd gear i knocked it down into 1st
