Well, I'm back with my breva stumbling problem. the replacement ECU and the new TPS didn't do the trick. I'm thinking I might try and find and replace the relay that controls fuel delivery. I remember reading somewhere that it might be the 12V30A relay second from the front under the seat. When I had the bike out the other day the relay seemed warm when I got back but I expect relays do that anyway. Is this the right relay to try and replace?
