Hope you get it fixed min.
Good tips above that you could try.
I managed to flood my engine after fitting the bigger injectors so I had to remove/replace the plugs and it fired up 1st time after that. Was easy enough on my classic as all I had to remove was an intercooler pipe/water bottle and air filter. ABS makes it a lot harder to reach the plugs on drivers side but mine doesnt have ABS, yours will, PITA job. I don't think yours is flooded though, this is for info more than anything.
