My wing developed a antifreeze smell every now and again last year. A month ago I was coming home from work and my temp ran up to the half way mark and three quarter sitting in traffic. Got it home and topped off the radiator. two days later the temp ran higher than normal and I had to add more coolant again. Today I decided to pull the radiators and inspect them.I didn't see anything wrong. My bypass hose was hard so I cut some 5/16 line and used new hose clamps. the other hoses looked fine too. Got it back together and started it up to check for leaks. After the temp got to a quarter which it normally runs I noticed dripping around what looked like between the radiators. It was wetting down my coils also. The whole time I checked the coolant tank and it seemed to stay full. The water in it had plenty of anti freeze so it was good and green. I filled the radiator with plain water initially and the leak is clear to maybe touched with a little color. I just can't see where the leak is I pulled the rediators twice thinking that my bypass was spraying coolant up to that area. I'm officially at a loss. Are there any other hoses that go to the coolant tank besides the one from the filler neck and the overflow?? Any ideas?? It didn't leak this bad before I started this project. Oh well the shift shaft seal went in easy enough. Maybe I'm tired and missing something.

There are coolant hoses running to the carbs. One supply, and one return, entering the carb "heat riser" at the bottom of carbs. Also, supposedly, a thermo valve somewhere in this line.
Right I inspected them this morning. A friend and I discussed this earlier. The leak is coming from someplace high in the frame. The leak drips on my coils and the right radiator (from the front of the bike). I can't see any holes in the radiator and they were clean and free of green indicating leaks. I have concerns with the bypass hose I tried to replace I had 5/16 hose and cut it to length. I used new hose clamps on it too. I wasn't sure if this is a purpose made hose or not. Honda fiche shows the hose in bulk. I suspect either the puke bottle or around the radiator filler neck. I'll know more when I start work later. Still a little sore from crawling around the bike for 11 hours yesterday.
Never mind I think I found it. The level tube that go's in the reserve tank from the filler neck has a rubber grommet surrounding it and a wire type clamp holding the elbow in it. Looks like it's been leaking back there for a while the black plastic is almost white in that area from the water flowing past and drying. It puffed a touch of steam last week and I think that was the seals last day. Servicing the cooling system yesterday just brought that problem to the front now that it's the weakest seal in the system. Wouldn't you know it the stealership is out of stock and has to order it. Oh well I guess I can put the radiators back in and double check everything else while it's down this far. Sucks that I'm gonna be stuck in a cage for work next week the only upside is I get a/c for the week.

Had that same prob, ended up doing some engineering of my own to get it going. Also changed the radiator cap, it wasn't holding pressure, and changed those lines by the carb, what a blast that was. went thru a box of hose clamps just on that.

You keep saying green. this raises alarms. If you are not using Honda coolant or at least a coolant that does not have silicon your bound to have water pump problems in the future.
