Hi,
Wondering if anyone can help. Last ride out the bike was spot on. On Monday I entered an enduro and DNF'd in the first 1000 yards!!!
The bike warmed up on high idle and I then dropped it to normal tick over and everything was normal on the line. I revved it up and made left it sat on normal tickover and there was no evidence of a problem.
Got the flag and it kicked up first kick and set off fine.
About 500 yards later whilst riding along a forest track in 2nd gear it did a "cough stall" which I thought was odd but maybe it just wasn't warm enough yet. Still very odd as I'm running a rekluse in it. I wasn't on an obstacle just a forest track.
Started back up and this happened 3 more times in the next 500 yards until I could not get it to start at all.
I have since swapped the tank to see if it was the fuel pump but that made no difference.
It still starts and runs on high idle but cuts out as soon as you put it back on normal tick over. I have tried adjusting the idle speed and it makes no difference.
Can anyone suggest what to check next? I'm worried that it gets expensive swapping FI parts!!
