Phil when you had the rad out you should of removed that air thing pipe and blanked it.:team[1]:

i was going too but i understand theres more to it than just taking it out??? you have to take the 02 sensor out???

DUMB QUESTION ALERT: once you fill a rad and expansion bottle with coolant you normally start the bike and run it for a bit to get any trapped air out...then normally top it up (which in my experience is normally just a little bit).

But on the Ten you have to take the take off to top it up?!?!

You can use a funnel with a hose/tube attached to top the rad up without removing the tank - same sort of setup you might use for giving an enema! :runaway:

I think if you got the rad full and sum in the expansion tank run it up switch off and re start unless there's any bleed nipple.Yes you have to fit a blanker plate to the head,or cut he pipe off the flange braze or weld over hole.

im sure theres more to it than that, if it was that easy why have most people just blocked the pipe? you have to do something with the 02 sensor i think or else you get any error code.

i removed the AIS off my Fazer, apart from tapping the ports that feed the cylinder heads it was easy.

heres the blanking plate for the Tenere

You can just block it at the header. I'll probably do that soon. At the moment I've just plugged it at the airbox end and left everything else in place.


The bit I'm not entirely sure about is that, having plugged it, whether you can entirely remove the system, or whether you might have to leave just the servo in place to avoid an error message - the same way that seems to happen with exhaust valves on sportsbikes.

I'll let you know when I try it.


The O2 sensor is an entirely different thing.

I am going to take mine off all together,but to cold in the garage just like the elephant rally.Been running my bike for about 4 months with the valve disconnected.this opens the valve so you have to plug the pipe to the air box.No error codes.:team[1]:

filled the rad up....filled the expansion tank up (ive used Yamaha coolant) and put the tank back on.

now then...........you are right, if i need to top the rad up (after running it to get rid of any trapped air) i can use an "enema funnel pipe". BUT....i cant actually SEE inside the rad, so if the level has dropped due to trapped air....how do i know??? :)

i reckon if i rock the tank back a bit (lift it up at the handle bar end) it should be enough to be able to peek into the rad.

The Tenere is the most awkward bike ive ever worked on :angry5:

If you top it up slowly with the "enema method" any excess will flow down the small expansion pipe and leak back into the expansion tank (provided you take the cap off the expansion tank while you fill the rad to let the air out, at that point it is full. Or alternatively top it up quickly until it pisses all down the side of the rad! :eusa_doh:
