the bike is a '00 750, but this would apply to all bikes id think.

Over in the Busa world there are a couple ways this is done. One strategy is to move the stock sensor from the cool side of the radiator over to the hot intake line coming off the engine. Its about half way down this page. http://www.rccturbos.com/product-cat...&category_id=3
Another option on the Busa (and I have to assume that there are parallels for other bikes , This appears to work in all of the Suzukis) is to use the fan temp sensor from a Honda Accord which triggers the fan at 185 instead of 205 I think. (it is a direct swap) Also a well used option is switching to a Muzzy or comparable fan the Muzzy is Aluminum so unlike the stock Suzuki fans they don't flex when they get hot. Muzzy also seems to have better Geometry so it appears to move more air.
I actually did all three but the fan ran constantly so I switched back to the the stock sensor in a new location.
An option for gen 1 busas I haven't done but may is to add a second fan from Jeggs or Snitz (they are $50) so you are moving even more air when the fans run.
