Was taking my old exhaust off today and noticed i had no fan for the radiators. Bikes been running fine without it for past few years, is it really important? Its a track bike now anyway. Thanks

If you've had no problems mate then i should think it will be fine. I'm no expert though!

i agree. on the track, your going fast enough for the air to cool rads down.

if your sticking it back on the road, i would put a fan on it. ever little bit helps for annoying traffic jams overheating engine

The bike will cool much better on the track with no fan.

my track bike has no fan :),just make shore the fins are stright and clean (use a fine bit of wire and take it really really easy) its a timly process but worth it and she'll be right mate :)
cheers Tim

Nice advice tim, Thanks for the replys

as soon as the bike is in motion a fan will not make any effect it only is for when the bike is static. pointless on a track bike
