Spent some time trying to get the new injectors in. Got that all done today new bigger throttle body’s. Changed my injector size in ecotrons to 240 g/per tried to dial my higher end fuel down a bit in the fuel map. Found the manual for the 300 and it lists 2 1/2 turns for the air screws so I set them both to that. Problem now is it won’t start. Almost started got about 7 revolutions then quit. Let it sit tried again got a pretty bad backfire/ out the exhaust bang. Kinda worried to keep trying. Any suggestions I tried to take a bit more fuel. So I put in 250 g/per in the injector spec and still not starting. Running out of ideas? I did hook up the map to both banks of the throttle bodies but I’m almost suspicious about those air mixture screws my old ninja 250 throttle bodies were barely open. One at 1/4 turn one at 1/3? Getting frustrated gonna take a break until later.
