Hi all, been struggling to solve a fuelling issue this last week, hoping someone can help, I’ll put below what’s happened to date (2012 1200gsa)
1. Fuel low, filled up on way to work, on way home, surging, erratic idle, bike cuts out at lights. Restarts after 30s with a bit of throttle and on the 20 min ride home, bike settles down
2. The next few days, no issues then the same happens again, difficult to start , bike surging as soon as I throttle on or decelerate and then catches itself . Lots of bang and pop though
3, started to think bad fuel, so ran tank down. Also checked visually all fuelling connections, cleared breather hoses, checked the tip over valve. Left side breather may have had a restriction as wd40 didn’t flow immediately through
4. Took out for s ride yesterday, all fine, ran tank down to 60 miles. Fuelled up with premium unleaded from no. Set off and weirdly, the fuel gauge is very slow to register the extra fuel. It should have gone to about 150 but by the time I got home it was showing 100 (should have been about 135). Bike running perfectly though
5. Come to this morning, difficult to start and after a couple of miles, bike cuts out completely (dash is on). I coast to a halt, open filler cap, restart engine first time and it runs sweet all the way in
Sparks and coils replaced 6 weeks ago along with air filter. Seems odd it started straight after a full fill up of tank - I was thinking that maybe it’s the last of the crap to go through but this weird fuel gauge issue and the opening of the filler is making me wonder whether it’s something else
Any help really appreciated as ever
