I actually rode the bike after installing the FI and before I put on the exhaust. I noticed a few things. More immediate starts, runs a lot richer, flatter torque curve. I am not planning to have it dyno'ed to prove it. I thought it would be a good idea for under 200 bones since I was changing out the exhaust. With the new exhaust I am only getting occasional mild backfiring on decel also.
