Ive often thought that a rad cover would reduce the air to the rad (I dont have one)

I've got one, never had any issues.

Not an issue but

I've heard mine come on a few times

By the way not trying to have a dig ---thank you for your help and wisdom
I would have a guess that the only people to have had the fan come on while riding are those with a rad cover ??

No not at all, because it makes no difference whatsoever when the bike is sitting still?
They have holes in anyway.
Fans are there to draw away the heat, it wouldn't bother me if mine came on frequently, hence the reason i've hot wired my laptop cooling fan to be permanently on, because they do a good job!

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!

Yeh you are right about me thinking so much. Im gonna let it go  thank you.
NOW where is that thread about aftermarket rad covers because I want one ! 

[His Dudeness]

You should start up the engine and rev it up a bit or better yet go for a spin to get the air to the top of the system. Then check the coolant level again at the cap. Let the bike cool down before you take the cap off or you'll get a face full of boiling coolant

Just been out today and will have another look sometime soon

[fazersharp]

Had another look today and got another 20ml in it (rad neck) and thats it now.
All the shaking bouncing rocking and running on the spot that you do is no comparison to going out for a proper ride to get those air bubbles to the top

Bump for you

Bump for you

Many thanks

When I changed mine I couldn't find the drain bolts on the engine block (???) or something. I forget what Hayne's said, but I did the bottom bolt, and found the reservoir, but couldn't find the other thing it said to drain.


If anyone has some info (and a handy pic) on this I'd appreciate it for next time.

[Dave48]

It wont flow out the drain hole UNTIL you remove the rad filler cap under tank!! :lol

[thunderpantz]

That said, I remove the drain bolt prior to removing the filler cap. If there are any leaks the fluid should trickle out. If the fluid doesn't budge then the system is air tight

[His Dudeness]

Just take the lowest hose off and sorted. You'll get a bit more out too because the hose is lower than the the drain bolt.

[andybesy]

I think its only the yzf which has drain on cylinder

[darrsi]

How many blokes does it take to undo a bolt?  :lol

[fazersharp]

No need to take off the hose and there is no engine drain bolts just 1 bolt on the pump thats it.
cap on blolt out, bucket under- cap off ---take a pissing photo - kick bucket closer to bike as pressure drops. 

[His Dudeness]

Or just punch a hole in the rad with a flathead screwdriver it'll soon drain out. better yet kick the rad off then you don't even need the screwdriver :lol

Which will explain why I spent 30 minutes looking for something that wasn't there.....
