Used my sb6 in a hot part of Australia for a while and used to get hot in traffic so I put a manual switch in the fan circuit fixed that problem

I use a Davis-Craig adjustable unit for controlling the electric water pump and radiator fan on my GT750 track bike.

You might be able to find a Muzzy fan. Its has metal fins with a bigger surface area

I have done the same on my Dieci. Wired a switch in parallel with the radiator temp switch. Otherwise the bike is very hot before the fan cuts in normally. Tend to use it if I know the temp will be getting high (ie, getting in to traffic)

All the best

EC,

Just in case it's the switch that's dodgy you might want to think about trying this...ÖÖ.. the temp switch on my SB6 didn't start the fan until the water temp was v high. I was advised to fit an Intermotor 50332 switch (Nissan Primera or Nissan Sunny) - M16 x 1.5 thread - as it was claimed to lower the temp at which the fan kicks in. Since the fix was dog cheap I tried it and, as a pleasant surprise, it worked! It's been fine for a number of years now.

When i looked at the switch earlier today i thought it was sligthly different to the Suzuki part and i think it might be one of these.
Good to know - thanks
