radiator

[2kwacks]

noticed that my radiator is starting to gather dirt between the fins behind the rad gaurd. will removing the rad gaurd at the weekend and try to flush clean with "low pressure" hose pipe if that dose not work, will try to blow it out with my leaf blower, any other suggestions that won't damaged the fins?

Hose pipe will do it.  Get it wet then flush it from inside fairing if you can.  Give the rad guard a scrub too!

front wheel out and fender off , and get in there with some muck off and a scrubbing brush, just done mine like that and got enough dirt to re pot  some plants

Scrubbing brush on the radiator?!!

[viper]

wrongly described brush, my rad guard is fitted and i use a car wash brush with soft bristles, no damage to the fins but gets through the rad guard and lifts the dirt out

+1.. be gentle, fins can be damaged easily. soak the rad first to soften the dirt

Always clean the rad from the inside out.

 I,ve just cleaned the rad, it was not as bung up as first thought. had a quite a few bugs here and there and the normal gathering of dirt in between the fins. so removed the rad cover, did not fancy using a hard brush instead got the wifes "hoover" which as a very soft brush attachment, turn the hoover on and gentle brushed the rad and suck the out done the trick then washed it through with the normal free flowing hose pipe looks like new again just need to clean the brush attachment  for the hoover before the wife hoovers her curtains or I will be in the

The R1 always had the rad soaked before cleaning with a soft toothbrush. The GTRs fins look closer together and significantly bigger. How do you hose it from the inside- or am I being dense?

I found no problem hosing it down from the inside, I just removed the flow attachment from the hose.. "this way the hose is more flexible" you then can get the hose between the fairing fins on either side and pinch the end of the hose to create more water pressure. this seem to do the trick spot on! your can see the water flowing freely through the rad from the front
