Oil cooler thermostat

[Pykie]

Hello all,

my ride to work is a fairly slow 7-8 miles, and this time of year my 1100gs only gets up to full temp as i ride through the yard gate. I fancy the fuel economy seems to be worse of late, and this can't help. It would be handy if I could get it to warm up quicker.

I can't do a lot about the cooling to the pots as they hang about in the wind, but I could put a cover over the oil cooler rad, if it makes any difference.

Mr Haynes here claims that 'on r1100s and all 1150 models there is a thermostatic valve ...... in the crankcase under the [oil cooler] union on the right side of the block - it controls oil flow through the cooling circuit'

This would put it next to the oil temp sender, and i guess that this is the supply side to the cooler, with the return to sump down on the left.

My query is, is it possible to fit one of these thermostat doodads into an 1100gs block? (I guess an r1100s motor uses the same cases?) will it make any difference? how expensive would it be? Should I bother?

Thanks,

Olly

Not sure, but I think the later 1100s had a stat in there, I use a piece of plastic oil bottle to blank off about threequarters of the oil cooler grille and that gets me up to five bars in a reasonable time.

IIRC the thermostat controlled bikes had different hoses as well which makes it a bit more of a job. Also, the later types had a bigger cooler hence more need for a stat.

The warm-up on my '96 1100GS improved noticeably when I changed the oil to a 10/50 synthetic (Q8 I think).

Failing that, just blank off half the cooler.

ps This is definititely NOT an oil thread

According to Clymer the 1100RT had a thermostat. Dunno whether or not it would fit on a GS. The fuel consumption records I have kept for all my vehicles show that consumption rises in the winter, thermostat or not.

The 1100RT also has 2 plates that block the air trough the cooler. I shut those and I get to 5 bars on the RID in notime, almost like in summer

Thanks for the replies.

It seems that Stewart H might be right, and there is actually a thermostat in there already. Now that Ive started to pay attention its obvious the cooler doesn't even start to get warm until the engine temp reaches five bars.

Never mind. I'll just ignore it then. FYI the bike is a '98 Gs1100 german import.
