What he said. <g>

The Tupperware Dragon rode perfectly until I took it into the shop for the 24K
service. After I got it back, it started being REALLY hard to start, and would
occasionally just die at speed.

I had to take it back to the mechanic for them to finish a few last redos (I now
have an auxiliary plug in the glove box and some metal under the plastic tank
? need more, but it semi keeps my tank bag on) and I mentioned it to them.

Just after getting it back, I headed for Raton, NM, and it did it again. So,
knowing there is a Honda shop here, I rolled in, described the problem and the
mechanic said it sounded like a fuel venting problem. He walked outside to the
bike, had me open the cap, and "whoosh!"

Now, being that PCs are unusual in NM, and probably even more so in Raton, he
started looking for a crimped hose. After reading the manual, he said the fuel
cap is supposed to be self-venting, and he designed a bypass since it didn't
seem to be working.

My questions are:

Is the cap self-venting, and do they just go out or is there something else I
should look at? (I haven't ridden the Dragon since it was fixed except to get to
a friend's house. I'm hoping to head out tomorrow for the HIghway of Legends.)

I now know I can make it back to Roswell by just opening the cap, but if I need
to buy a new cap, I will do that.
