Hi Folks...a question..I'm kind of a "C+" mechanic...can do the basics...oil change, chain tightening, air filter...etc. My '11 KLR was "cutting out" or running poorly recently, kind of like it was running out of gas. My friend (an "A+" mechanic) took the carburetor apart and cleaned it...with me cleaning the air filter and all of that good stuff. It really seemed to fix it. However, when we put it all back together, I noticed that I no longer had the clear reservoir tube that comes out of the bottom of the bike. I think I see where it hooks on...but am not sure... It looks like there may be a small opening underneath that would be hard to get to. I suppose the thing could have fallen off on the trail, I'm not sure. Any pics or anything of where it hooks on? Thanks for your help...I don't know it it's "necessary" ...but am fairly sure it should be there....Thanks, J.
