Hi all,
Have a stock M600 carbed, from 2000.
After replacing the pickups with P8s and having the bike running again, I noticed backfiring when decelerating.. ???
I got the bike for less than a year and I haven't changed too much - I used it as the previous owner sold it. (I did replaced air cleaner, fuel filter, plugs, and oil)
Now I got the Ignitech unit and in one week I'll finally get to my bike -but this troubles me because I'm afraid I'll make it worse by installing the Ignitech.. :-\
Where should I look to identify the cause of backfiring? Carbs (I will check the mix) spark plugs? what else?
Thanks and any suggestion welcome! [thumbsup]
Popping on deceleration, many times is tied to a leak in the exhaust system. Like the join from the header to the slip-ons. Since they are nice and easy to deal with - loosen the connections and mounts work the cans to ensure that they are as well seated as possible.
Other stuff can cause that popping as well - but start simple first.
will check, thanks!
Or fuel/air setting is too rich/lean. You want the part of the plug that sparks to have a light brown color; ideally.
thanks guys, the exhaust is fine, I've checked it.. Not sure about the mix - any ways to find out (apart from checking the plugs and the exhaust) and set it properly?
I have re-set the mix, it was only 2 turns, I made it 3 and is very promising now - only sometimes would 'hesitate' when revving from idle..
cheers
