Trying to replace the Rad fluid ,antifreeze in my 83 GL650i,found the drain for the rad,but that's it,is there something I'm missing as in another plug in the block/cylinders.........



Not sure of the condition of the fluid and it gets cold here I do not want thinks freezing and breaking.



Did a couple different searches and read several posts but I could not find what I was looking for.

If you want to drain the cylinders, there are two bolts (one on each cylinder) behind the radiator. You need to pull the radiator to access them IIRC.

Awe....#$#@#.........I was hoping for something simpler..looks like I should just re-fill with clean new fluid and run things to mix it together.........





I was trying to store it until next spring when it's warmer and really get into things,inspect and replace.....



Thanks for the reference ..... good pic..

LOL... or you could just disconnect the lower coolant hose like the pictured motor.

That'll get most of it out, but if you really want to drain it those bolts are the way to go.

He's talking about storing it for the season... regardless of how I drained it. I would be sure to blow dry it as well. I doubt if you could ever get ALL of the water out of the thermo housing without removing it. then again I also think you can remove only one cylinder bolt, tip the engine and the water will all go to that side...( that's how I did it on my 82cx) It's really not that hard to get to, and it never hurts to see the drain plug area, fins , fan etc. I removed a perfectly good fan from a 78cx motor the other day. On close inspection, it had developed splits in the back side radiating outward from the hub. Other than seeing it, the next indication of failure would have been fan disintegration...



someone chime in here. Is it ok to store a used motor "Dry"



Personally, I'd keep it wet: both coolant and oil, due to 30 year old seals , chance of corrosion etc.



Off Topic: See topics RE: ethanol in gasoline fuel ... if you're going to put it up with ethanol in the tank, be sure to run that crap out of the petcock, carbs and motor. shoot a little lite weight After run oil into the chambers. If I had stored my bike with e fuel. I'd drain the tank before starting it. even if I put in some Marine Sta bil or other fixer.

The two drain bolts are there for a reason.



You can't win really.If the coolant is drained aluminium oxide will form in the dry coolant passages.If it's left in and not disturbed minute crystalline deposits will form.These won't be much for say a 3/4 month period but over the years they will build up unless the cooling system is flushed properly.

The best option is to put some REdX/Seafoam type stuff in the fuel and start the bike once a month and let it get to Thermostat opening temps.Some will say this will cause more engine wear but if that were true then every time the bike is stopped in traffic it would be under the same conditions.

Having left my bikes idling for well over 30/40 mins at a time whilst testing my electric fan conversions and checking the oil I've found no evidence of extra wear by metal particles in the oil.

Keep it wet! If you fill and drain the system twice and then drain, add atifreze coolant. Ride the bike to mix, ready for storage. I use the 50/50 mix from the auto store.

Just my thoughts.

I just bought this piece of.............machinery,and have not had much chance to do anything to it,I checked with my hydrometer today and the antifreeze/coolant would not stand up to the below freezing temps we get here so I wanted to replace the coolant/anti with fresh stuff to save the engine/rad/hoses,and get at least one job done.

Are those "metric" minutes?




After reading this I think i might... put E alchohol in my coolant syst for the winter... a liter of TAAKA ought to do it.
