there is a little hose by the water pump hose coming out of the engine where does this hose go to and what is it ive built this thing from the ground up i cant seem to locate anything about it in the manual any ideas?

I think it is a vent that runs to the rear of the motor and blows by the back of the case.

it's a vent tuve that plugs in behind the water pump cover. 3 screws---> plug it backk in :thumbsup:

ya no big deal I bought a cover that it was plugged off so its not a big deal I would vent it since that is what they did from the factory

I just left mine about 6 inches long. But It should tee off another vent hose near the rear of the engine up by the rear mount. the 2 are supposed to tee together and vent up near the radiator/handlebars. I think thats how its installed by Yamaha. I built mine from ground up too, so mine was never hooked up.

you are correct it does tee off and tie into the other vent lines. i just have heard of guys wanting to silicone the hole closed. Imo thats not a good plan.
