I have an 05 RG with an 04 engine, stroked to a 96", set of woods geared cams, heads p&p with new conical valve springs and over sized intake valves, VH 2 into 1 pro-pipe, an Arlen Ness big sucker air cleaner, and a t-max with an auto tuner. Yea I know its a Frankenstein with approx 180k miles, but until last Sunday, it would run like a BOOH. Know that you know what I have, here is my problem. It started all of a sudden, parked the bike Friday night, ran fine. Fired it up Sunday, and problem begins. Its starts and revs to about 2000 rpms' for about 20 seconds and then starts to die. I roll on and off the throttle and that keeps it going for a little while longer, but eventually dies. I changed the fuel-filter because it was restricted. The air is not restricted. I don't have a fuel pressure tester to test the pressure (if anyone knows of a good inexpensive one, let me know). Has anyone ever experienced something like this? I have not recently changed anything or adjust anything on the bike. Any help would be greatly appreciated.
