I recently purchased a 92 gsxr 750 that had been sitting for the last 2 years. The previous owner pretty much ran the bike at the track. It has high lift cams, a ported and polished head, stage 3 jets and a vance and hines supersport exhaust. when I bought the bike it was not running, so I rebuilt the carburetors and it fired right up. The only problem was that the bike would not idle with the choke all the way in. I took the carburetors back off and re-cleaned the pilot jets and now the bike will not start. What I thought was the carburetors seems to be an ignition problem. I checked the coils and the signal generator and both of those checked out fine. I still am not getting much spark at the plug. What would be the next thing that I should check in the ignition sytem???
