Noticed my bike just does not feel like it has the power it once had. Thought it was me just getting used to it but now I'm not so sure. When I first got it, it would pull like crazy above 3500rpm sliding you back on the seat and the front would start to lift but now you can hammer it and no pull until 6000rpm+ and even then it's no where near what it once was. Any idea what could cause this loss of power. The bike has a Ti-Force full exhaust, BMC air filter, Power Commander and TRE all of which was on the bike when I bought it. I have put about 2000 miles on the bike so far. The only glitch I have noticed was one time the shift indicator showed it was in 1st for about 3 miles and then went back to 6th like normal with the TRE. It hasn't done that since.
