    Hoses to nowhere?!?

    Hey all,

    I'm a newbie, and I feel kinda lost right now. I'm stripping down my 80g to get her running again and keep finding hoses that don't go anywhere. (ie. from the gas tank where the seat touches it to nothing) I'm snapping pictures before and after I remove something so that I keep track of everything, but when I find a loose hose, it gets to me.

    The air box was removed prior to my purchase and replaced with K&N pods. I've noticed there are some other hoses around that area that don't go anywhere...did the airbox have multiple hoses going to it?

    Also, are there supposed to be holes in the interior of the rear wheel other than the one for the air nozzle? I'm losing air through those.

    Thanks!

    Early 11s has tube-style rims, and there were two extra holes in the rims for rim lock devices. Take a close look at the rim; if the word Tubeless is not cast into one of the spokes or rim, you have an early rim.

    If that is the case I would look out for a newer tubless rim, either from someone on this group or through eBay. The rim design is a bit different between the two, and there is some controversy about running tubeless tires on a tube-type rim. I don't recommend it, myself.

      hoses

      My 79 has 3 hoses going to the airbox. 2 carb vents and 1 crankcase breather. Not sure about an 80.

        The hose off the rear of the tank is the drain from the gas cap area. It goes behind the engine and allows the water to drain to the ground, as well as any gas you may spill while filling.
        The 80 should have one hose, almost 1/2", from the back of the engine that went to the airbox. This is a breather for the engine. I would put a filter of some type on it, and leave it up near the air cleaners. You also have a smaller hose, about 1/4", that goes from the middle drive at the left rear of the engine up to under the gas tank. This hose is open, but MUST GO UP, NOT DOWN!! If it is run down to below the engine, you can pick up water and fry the bearings in the middle drive unit!

          Ahhh....

          Yes...it's all making sense now. I have a spare filter from my parts bike that will work on the 1/2" hose.

          On a completely different topic, but one I was thinking about tinkering with on my parts bike (since it runs). Has anybody tried to replace the carb boots or retrofit an end peice so prevent the lovely $40 replacement for each boot that cracks or breaks when cleaning the carbs?

          Both of the bikes have glue or epoxy coving the boots which is making the removal of the carbs EXTREMELY difficult since they don't stretch or flex anymore.

          I was thinking some type of clamp or pvc pipe to wrap around the boot, sliding radiator hose or some type of hose that fits and won't get all weird from the gas with a clamp to hold the carbs. Possibly a bracket screwed into the top and attached to the frame under the tank if the weight is too much at that length.

            How are you cleaning the carbs???
            I Pull the carbs OFF the engine and THEN clean them. after a little practice, it only takes about 20 minutes to pull them, and thats WITH the stock air box.

              Same way you guys do...

              I clean them the same way you guys do. Remove tank, hoses, throttle, open clamps and remove carbs.

              Maybe I just need to get new boots to start out with because both sets have that gunk on them like they were cracking and the previous owners didn't want to spend the dough to replace them.

              How long do the boots last for you guys typically? 5 yrs? 10?

                Hey Austin,

                My boots are 25 years old, and are still working fine. Yes, they are cracked on the outside, but that is merely cosmetic! They are dual walled! There has been recent threads with different ideas on how to make them more aesthetically appealing!

                One is to put electrical tape around them! I'm not in favor of that due to both the tape glue and tape itself withstanding fuel and heat!

                The black RTV coating technique you are apparently familiar with!

                I found some nifty plumbing pipe rubber sealant/insulating type of tape at Lowes a while back, and used it around the PVC pipes I put on my air filter side to mount my velocity stack/indy filter mod! I had used duct tape, but it didn't hold very well, the glue slid around and the filters started to slide OFF the PVC pipe! I put the rubber tape on, and they are staying put! YMMV!

                BTW, you can get a complete replacement set of 4 for about $90.00 from Ebay ....Georgefix seller name, or also Partsnmore.com, and other sources OTHER than the STEALERSHIP prices that you seem to have quoted!
