Engine Backfires and quits

I have a 2010 FE570 with about 30 hours. The bike, after it has been run for a while, starts to backfire and eventually quits. It will turn over but won't start until it has cooled down. When it does start it runs completely normal. The problem is getting worse as time goes on. What should I replace or check?

Do the obvious stuff:
Check Battery Terminals are tight.
Change Spark Plug
Check you have not oiled the Air filter too much.
Check not too much oil in the engine


Then check this post:
viewtopic.php?f=7&t=12991
Check the fuel tank for gunk
Long shot but check valves
Then a trip to the dealer

Re: Engine Backfires and quits

Hello bcbush
My 2010 450 had similar symptoms and I have just found out the fuel pump is faulty. Still under warranty which is good because a new one is around $650 aussie. It is easy to check the pressure, which should be around 3 - 3.5 bar but hard to access a gauge. My pressure was 1 bar and getting worse quickly.

PROBLEM - bike quits


FAN WORKS
TEMP SWITCH WORKS
is it fuel? is it vapor lock, is it heat, water pump into the engine

2010 570, 50 hours, well taken care of, fan, wrapped akrapovic pipe,


anyone put insulated foil tape under tank to keep heat away from fuel pump???


right side tank turns different color, frame gets really hot, frame touches tank

I'm trying to track down a similar problem on my '10 570 with 8 hours. Check out this thread about Fuel pump heat and also some tidbits towards the end of the thread about electrical connections at the injector:

Re: Engine Backfires and quits

Something else to ponder. I like this idea due to the "backfire" issue.

Don't forget to check those pesky spark plugs and spark plug caps.

Re: Engine Backfires and quits

I ran into a similar issue, and when I checked the plug, it was not gapped from the factory as per the recommended specs. the gap was so narrow that I can only conclude that once it became heat-soaked the gap closed off and shorted, causing the bike to die until the plug cooled off. I re-gapped to recommended spec and have never had another issue in the last 32 hours... Except for a tankful of watery, sludgey fuel, but that's another story...
