under the tank-hose question
 

the smaller diameter hose that is going right up the gas tank, the one that has a hole in it, i believe is the breather hose. correct me if im wrong. is there a reliable way to repair this, or do i have to replace the hose?

Your right, You could just cut that part off...My breather hose is about 3 feet long, and it goes to the front of the bike, is this correct for you?

Yeah it's the breather tube. That close you could just cut it south of the hole and stick it back on, or replacing it couldn't cost more than a couple of dollars.

Duct tape....but like said above, vacuum hose is cheap.

i thought thats what it was. im not entirely sure where it goes on my bike. ill have to check, i just got done changing my spark plugs and i didnt want to get distracted buy anything else. ive definitely got some more work to do on the bike, so ill find out where it goes tomorrow probably.

sounds good to me. im sure replacing it wouldn't be very difficult.

i like this solution. haha. ill probably just cut it if i can get away with it.

one more question. where the hose fits onto the bottom of the tank, should there be a clamp of some sorts? ive got plenty of extra clamps, so i it would be a problem tossing one on there, but is it necessary?

No clamp required. It doesn't carry liquid fuel unless you overfill.

cool. makes sense. thanks
