I have a Fazer that runs great, minus tuning the carbs a little. I have been slowly replacing things on this bike. It ran when I bought it so of course I took it apart and rebuilt what I was comfortable with... Carbs, forks, brakes, lights, full tune up. I recently replaced the ignition and all of a sudden it shuts off as I'm riding down the road. I put the old ignition back on and its still doing it. It runs fine as long as I'm gentle, as soon as I give it some gas it wants to die. It starts back up no problem but I can't figure out what's causing the issue. HELP

Check your battery terminals, etc. Probably have a lose connection somewhere that disconnects when you accelerate hard.

My first thought would be a bad connection in the ignition wiring. Does all the power shut off, lights, instruments, etc?

It could also be a fuel issue unrelated to the ignition system.

I still have power. I thought it was the ignition so I put the old one back on but had same issue. I'll check the wiring and pull the carbs. Will update

Does it also do the same thing in neutral when your parked

No, it runs fine. If I go easy around the block It doesn't stall. Only when I get on it and shift quick does it stall, usually in 3rd or fourth gear

Maybe the bikes vibration/road bumps are causing it to shut off or you could have something out of whack on the carb . Make sure you cleaned the carb well and got it back together correctly. Bad gas? You didn't change any Jets when rebuilding the carb?
