Afraid things have got weird.Picked bike up from techy, 10 mile down road red ignition light and FP1 code flashing on top of dash, but engine runs great.Pulled over, swiched off and then restarted.All looked great then same again 15 mile down the road.Took bike back to the techy explained problem.He did a diagnostic, and their was no faults stored, and he's never heard of FP1.He is now going to contact the boffs at Suzuki.
As the bike was running great I zipped of home 40 mile detour wih no problems at all.
At home had lunch, 30 min later tried to start bike.
It started first time but ran like a bag of hammers,same has the original fault, revs had be kept high or cut out , and sounded like fuel starvation.Switched off.Tried again this time all correct ignition lights came on,fuel pump sequence sounded normal but no start from starter at all.Tried again no luck.Then third time lucky, started and ran like nothing was wrong.Took the bike out for another 40 miler with no problems at all.
Durrrrr! Gremlins.
Taking the bike back to techy on Monday.
