Hi all,
Just a weird thought ..
Has anyone (in cooler climes) tried running a 14 without the radiator?
In days gone by bikes rarely had radiators..
Just think of how much easier the cleaning would be.
??
Cooler climes? T24 cooler?
I guess you'd have to assess when & how long the valve opens to the rad to allow oil cooling prior to undertaking such a thing. Reckon this could be achieved by adding some sort of flow meter in the line somehow, to show when it's open & when it's closed & for how long, then do a temp 'blockage' (tap) in the line & see how it goes prior to taking it out of the circuit.
Easier to just clean it though isn't it?
or is this a wind up like Vlads shaft drive 14?
"In days gone by" bikes were designed to be air cooled, any oil coolers were an extra.
The 14 was designed to be oil cooled.

There is no valve there Col. It's a mod I am thinking about doing (the valve, not the taking off the rad :doh:)
Where is the valve that stops the oil cooler draining when you do an oil / filter change ?

There is an oil control plunger (#22) in this pic: (https://gsx1400owners.org/forum/gallery/0/736-090618213501-6061851.png)

I don't think it hinders the draining of the rad. It's purpose is to allow a way for the oil, if there is a blockage on the way into the rad (example: thermostat mod), to flow into the filter.
Why does the rad not drain then? On the output side it has to overcome the height difference to the location of the filter. Can't flow back towards the input as the oil pressure relief valve (#21 in 1st pic) resist.
The relief valve and the control plunger are pressure (not temp) influenced.
Oil and filter change is less than a full rebuild or fitting a new or empty rad.
I was under the impression the rad didn't drain back out.
EDIT: The manual lists...
Oil Change... 4.2ltr
With filter..... 4.8ltr
Full overhaul...... 5.7ltr.
That is also my impression (still) Tony.
It can't drain completely as the 2 paths are resisting it. First the height towards where the filter is mounted and second the resistance of the pressure relief valve. The rad can only drain as much as it has enough power to overcome the height to the filter position. I doubt it can completely drain (partially - yes). I am not taking the rad oil hoses off just for kicks :happy1: Has to wait till I do the thermostat mod - then I know for sure?
P.S. There are also other places in the engine/gearbox where the oil "pools". Only a full overhaul will get rid of it.
There is still plenty of oil in the cooler when the bike is not running as I found out in Germany a few years ago when I blew a cooler and had to remove it to try and get if fixed .wasn't fixable so was replaced £££ .
:doh:
OK
The Rad stays..
I actually did have my fan cut in twice when I had my 14, first time when queuing on a hot day to get into Brightona, second time queuing to get into Brands on a hot day.
So they do cut in and are put there for a reason. Given the 14 was built on a budget by Suzuki in the first place clearly they thought they needed them.
Personally I would not have removed the fan, as there may be a day it needs to cut in and can't therefore. But that's me.
I don't remember my fan coming on.
Then again, I haven't claimed on my insurance but that doesn't mean I'm going to remove it!
Get the nugget out Speedy - those brown spots will be gone in no time.
My fan has come on several times during the winter :happy1:
Happened when letting her run in the garage for 30+ minutes at about 5° ambient. Screw in temp gauge showed about 100°. Since fan is supposed to kick in at 120°, there is a difference of 20°.
Without a fan I would pay attention to the temp gauge. If it hits 100°, turn engine off. :smoke:
I have had my bike for over 7 years now and in that time the fan has come on twice, both times commuting across london on a hot day.
On a long run my bike doesn't really get above 100
I have had my fan on only in dyno, never in real riding. Maximum oil temp I have seen on the road is 90°C
