Help! all of a sudden i seem to have loss 50% of my hp on my 2003 honda VTX1300 S. the pipe that leads to my back cylinder is luke warm which allows me to hold my hand at the end of it as long as i want, where as my pip that leads to my front cylinder is hot to where i cant hold my hand just like it should be. the bike still runs but seem to have half the horse power...any intel on this problem would be greatly appreciated...thanks
