Changing my coolant - any tips

[darrsi]

My thinking is that they are reducing the flow of air (even with the holes) so that when you come to the stand still that (non cover people also have) yours comes on and not theirs.
But as you say it comes on and it dose its job so no worries, although it does run off the battery dosent it - so if you have any battery issues ---maybe
I did not know that it draws air rather than blowing air though ---is that the same for cars. I spose that if it were blowing then it would be drawing hot air from the direction of the engine

You certainly are the pessimist aren't you..........stop thinking so much, it's really not doing you any good.  :lol
If you have battery issues, then, get your battery issues fixed or replace the battery?
How d'ya think air cooled only bikes survive?
At least we have coolant circulating and a fan to cool down the engine when the bike's not moving, so we're actually rather spoiled, and as i said earlier if the system is unblocked and fully functioning as it always should be then you won't have any problems.
You must remember that radiator grills aren't just added to look poncey, they are there to protect your radiator from stone damage, and they work 100% well in doing so.
You wouldn't wait in a queue jogging on the spot because it won't take very long before you're gonna overheat, so if you think the bike's ever gonna be sitting still for more than 10 minutes at a time, especially during hot weather, then the simple solution is to just turn the engine off (or stand still)........sorted!
