Yes, you have to remove the faux tank which means removing the lower fairings to get to the 2 bolts to get the tank off!!! Also the seat has to be removed which means MORE bolt removel !!! Really is a pain just to check or add more coolant!!
I too have found it a PITA to get to the radiator cap. On the Aspy, the faux tank is not so easy to remove without disconnecting the compressor hoses. I remove the seat ( I used to remove the saddle bags until someone on this site pointed out that the screws were accessible by pulling the rubber seal up a bit) remove the fairing lowers and remove the two screws holding the faux tank.
I can then lift the tank with the compressor hoses untouched and **** the tanksideways enough to get access to remove the filler cap. I have a funnel with a long stem that I use to top it up.
If you have blown the head gasket, I think you will find that the only thing that will fix it is a new head gasket. I went through that a couple of months ago on my Aspy.
If the head gasket is blown, you may find that you are getting oil blown back into the coolant and into the header tank.
I suspected that I had blown a head gasket and confirmed it by removing the plugs and stuffing a strip of clean white cloth into each cyclider on the suspected side. I left it there for a few minutes and could clearly see green flourescent coolant on the cloth when I pulled it out. Perhaps a bit unconventional but it worked for me.
Come on back if you need help with the head gasket. Maybe you could put your location into your profile. Someone might be local to you and willing to help out if needed.
Yep.I've found the Goldwing is like an MM Peanut. Gotta go through the hard candy coat, next the tasty chocolate coating and then the crunchy peanut.hahahahahaha Its a real PIA on just about anything you do on these things. If the bike wasn't such a pleasure to ride, I'd go back to a Shadow.
