I bought a 2006 Triumph America new from the dealer this past September. I followed the break in reccomendations of keeping speed slow and changing RPM a lot.
At 1000 miles, I tried opening it up and was really dissapointed to find that the top speed I could get to was 90mph. I am now over 2000 and haven't felt much of an increase in power or speed. I called the dealer and they said that this was about normal for a bike this size. They said I could expect maybe another 10% with mods, but that was about it.
I am at about 7000ft elevation, so the air is pretty thin, but I have taken it down to 5000 on some rides with friends and haven't seen much improvement. Also, bottom end seems to improve on cold mornings (denser air), but top end is still 90.
Is this all I can expect from this bike? If not, any suggestions on how to improve performance and how much of an improvement I can expect?
Thanks
Matt
