When I got my Warrior, in May '08, it had a Baron's BAK, a crappy map on the PC3, AIS block off, and Samson Street Sweepers with no baffles. I had it Dynoed at 82 hp and 98 torque. The air/fuel ratio was completely screwed up (super lean to super rich and gradually back up to lean by the rev limiter.)
I've done alot to the bike since then. I added a VBAK, and 2-1 speedstar headers with a resonated tip, AIS block off, Amsoil full synthetic oil, a much better map, PC3 perfect install, and a 31T front pulley. I just had it dynoed again, and my new numbers are 67 hp and 93 torque. The air/fuel ratio stays within the 12-13.5:1 area thoughout the rev band.
I live at 3,000 ft elevation, so I don't get the same kind of dyno numbers you guys at sea-level see.
When I put the VBAK and the Speedstar headers (open pipe) on the bike, I say noticeable gains on the butt dyno. Since I have added the resonated tip and the 31T pulley, I am seeing these losses in power.
I have some ideas as to why I'm experiencing this loss, in the face of performance upgrades.
1) I had my front right spark plug wire pull free of the boot. I fixed it (I think). It's not loose anymore. How can I be sure it's getting a spark?Could this be affecting my power if it's not getting a spark to the jug?
2)The resonated tip on my pipes. I had more power and torquewhen the pipes were open. Could this resonated tip be hindering me that much? I thought a baffled pipe would create more backpressure (Torque).
3) The 31T Front Pulley. Has this pulley changed my timing, and there by messed up my power? If so, what have you guys that have installed the 31T pulley had to do in addition to the pulley?
I really need some seasoned help here. Before I go and do anything drastic, I was hoping that one of you vets could help me make sense of things.
Thanks!!!
