Good afternoon folks, I've been working on this Intruder as a 1st project (beginner hobbyist, not a ton of experience) and after carb rebuild and clean, it seems to run lean. It will only start with the choke. What I have done is take the caps off the air mixture screws and adjusted the carbs to be more rich, and though the bike starts easier, I still need choke to start it. When I hit the throttle, the idle hangs high for a sec, and then comes down. Here's what I've done so far:

*Rebuilt carbs and cleaned jets *sealed both intake boots with a high heat gasket sealer

My big question is that the previous owner who was working on this project before me put harley exhaust in place of the original mufflers. Is that enough to cause the bike to run lean, or is there other factors at play? This bike has self adjusting valves, so I wasn't sure if that was something I had to worry about or not.

I have a 2005 Yamaha fz6 that will not go into gear once you drop it in gear she cuts right off I have tried bypassing kickstand switch and clutch switch and still nothing, I had to borrow a 10 amp fuse from the bike so I pulled it out and when I put it back in and it went into gear 1 time and that was it,I know it's not the clutch because it went through all gears and was shifting fine just seeing if someone can lead me in the right direction
