re: the riding at night thing. I agree with you in principle. But I also use the bike to run my wife down to the barn to check on her horse a coupla times a day. Just a bit more time for us to be together (I travel a lot). And, it's kind of peaceful to hang out and watch the horses eat. Something about a barn at night...
So when I'm home we trek the 2 miles or so each evening, and there are about a gazillion deer around here. I don't go faster than 30mph, 'cause I just KNOW they're in ambush, waiting to kill us (wife has hit two deer in the past 10 days with her car). And under these circumstances, I would really like to have better illumination out to the sides.
re: the foam -- I considered this but thought it would "insulate" the underside of the engine. Any issues with heat?
And thanks for the exhaust/suspension info. I'm going to check into having the revalving done.
