What is this hose for?

I've got my replacement engine installed, and tying up some other loose ends, one of which was this hose that was on the other engine. The one running under the air filter going to the front cylinder. The other end simply ties to it's twin on the rear cylinder. What is this guy? I saw some pics of another 750 with an ear shave that has blanks where this hose is connected, should I have those as well? The hose looks hideous where it is, and I'd like to get rid of it.

The blanks that you mentioned are also called "coasters". That is part of the ear shave process to remove all of the emissions stuff from the engine. I believe the hose you are talking about is one of the fresh air hoses that connect to the reed valve, which is the part that you replace with a coaster during the ear shave procedure. If you want to go ahead to do the whole ear shave, check out the thread for it. Just search for ear shave and you should find it.

So can these be simply capped off as they stand (something like a vacuum cap and a hose clamp)? I guess I need to find out exactly what these ports are trying to accomplish.

Sorry man, I'm not that versed in the details of the ear shave. Never done it myself. But I'm sure someone will be along shortly to help out.

Garage
the Reed valves are there to purge air into the exhaust. yuo can cap off the ports (that is what we call Marbeling) or you can take off the read valves and put a plate over the hole (coastering)
