Thanks for the advice,
I'll check the mixture, cause my temp seems a bit high still.
Yesterday I was riding to town again, it was raining during all the way and, the highest temp I noticed was 150° with slow speed, high speed averaged 110°.
City driving + using of clutch seems to make temp rise quickly.
To answer nishiki, I've had exactly the same problem as you with the stick melting,(I even posted a topic about it on here, but with no reply of anyone having had the same thing, so I thought my bike had some special kind of problem.)
Though now I think it has much to do with city driving&clutch + maybe something else ?!
Anyhow, my stick melted in Paris so it's of course related to traffic jams, still surprised me though cause I've never had the same thing on my previous ténérés and bikes.
You'll find the remainings of the stick on the little metal filter cage in oil tank + in bottom of tank.
Be sure to clean it, and carefull with the O rings sealing M6 bolts on conection while taking cage off, they tend to damage.
I think its impossible that any melted plastic has made its way thru engine, but check what you find in oil tank.
When you order new stick, don't forgett to order the seal, it comes sepately.
I think the best is to order it from South Africa or why not Europe, for example moto ward in UK.
Maybe you could use some kind of rubber and a little liquid gasket on the contact surface to make a temporar cover and fasten it tight with duct tape or something else.
I wonder if the overheat problem can have something to do with a compression leak in engine, making hot gas flow out around piston and heat oil up, it would be logic, but I doubt it cause my engine clock is only at 30 000 kms.
If you want to be sure, make a compression test as well.
Otherwise what first worried me was all the other plastic parts of the engine, why shouldn't they have malted as well?!
As the anti return oil valve etc..though later, I've seen no signs of other damage than the stick, so I made the conclusion its just the stick that is made of some cheap crappy plastic material..
I've heard rumors of wünderlich in Germany, selling metal sticks, so maybe it's a common problem after all..
Post here if you find anything new,
