02 Shadow 750 Ace troubleshooting help

[u/Familiar_Scheme5768]

Hi, as title states I could use some help troubleshooting my shadow 750. I got the thing in really rough shape, the last owner was an ape of a mechanic, stripped screw heads and spray paint everywhere. He had oil filled all the way to the threads of the dipstick!

I’ve replaced just about everything you possibly can on the bike. New radiator, brand new carb, new fuel cutoff, new rectifier, new fuel pump, new ignition coils+ plugs, new oil+filter, new short shot eBay exhaust (dude literally sawzalled Vance hinds pipes and I needed to get them off the bike asap).

So, with that in mind. My issue is that if I rip the throttle quick the bike will stall and shut off, if I ease into it it’ll go max rmp no issue, even in gear. It was doing this before replacing the carb as well.

Initially I had thought it was a lean issue, maybe not a big enough jet or a stuck float needle. So I went up a jet size and the bike would flood after a few minutes of riding.

I’ve read something before that maybe the shorter exhaust isn’t allowing enough back pressure to the carb for the initial rip on the throttle, but I’ve also read that that’s a myth and a non issue with these bikes.

Any insight is appreciated and I’m genuinely sorry if my writing style is horrible!
