Hi, replying to Capt Bob re: bike config.
Captain, I'm running 100% stock. It is a 2007 classic, so I do have a windscreen and bags. The bike has 5k on it now.
I finshed the trip back from PA yesterday, and re-calculated the mgp. I was down to 37, though that's probably because I rode through the mountains to Gettysburg on Friday..........lots of twisties.
I fully admit I was enjoying the views and the beautiful PA country side.......in fact, I'm really impressed with central PA!!! What a great place. Therefore, I was not killing it on speed. Plus, there was a LOT of sand and debris on the curves from the winter, so I approached each curve with caution to manouver away from sand.
Some other commentary..........what a bike man! Though the Alleghenies are not huge mountains, the Rocket flattened them out. I only had to shift to 4th on the tight turns (the ones that said 20 or 30 mph), otherwise could practically stay in 5th! Believe me, I probably used half of its capability. I actually have ridden to 18,380 feet in the Himalayas (was in the mountains for 7 days) so I have expereienced extreme heights. I think the Rocket would laugh at them too, though it's probably too heavy for some of the trails we were on, fording streams, etc.
Anyway, I seem to be getting great performance and good miliage considering these other posts. I wish I could tell you more, but I have done nothing to the bike, though I'm sure I am not the most aggressive rider on this site, which will improve mileage.
That said, I have to agree with the advice that if you're getting in the low 20's, that's so far off the mark that it's worth checking out.
