Hi guys, I recently bought an 07 ltr 450 and it ran perfectly fine. Then I proceeded to upgrade a lot. I put a full dasa exhaust, pc 6, fuel customs intake. Then now it doesn’t start and if it does it bogs down and cuts out. I have done the swirl delete, changed the fuel injector, drained the tank and cleaned it out, changed the spark plug, checked the tip over sensor. Nothing seems to help and the red FI light is blinking. Any input on what’s next?
thank you!

based on what you just explained I am thinking you have to check your valve clearances seems like that your issue. if valve clearances are in spec then you're next go to is the decompression mechanism on the exhaust camshaft I am having the same issue at the moment and looking for a new decompression mechanism or a way around it. I'll let you know once i get it figured out.
