I can tell you the busa t-stat begins to open at 179.6 and is fully open at 203. Maybe the 600 is the same but ask Rowyco - Tim will know.

I as gene have a bung in the rad, tho mine is on the hot side of the rad. my rad flows up and down and is a 2 pass....so it goes in 1/2, then down and over and back up the other half and out to the water pump...


so my question, is it ok on the hot side?

I'd rather have mine on the hot side, although the stock is on the cool side. If the engine is running at all warm, the fan will be on all the time, unless it cools the liquid enough to where the thermostat just opens.

Bug on my second build I have the switch on the radiator inlet and it works fine. *It is that way on purpose. *I tried it on the outlet and on the inlet. *When I first built the buggy I mounted it on the outlet. * *Because of the firewall there isn't much natural air flow to the radiator on that buggy. *The radiator is fairly large (in comparison to the stock bike radiator). *With the switch on the outlet side the fan would kick on and pull enough air through that it would then kick right back off again after 20-30 seconds or so. *Then it would kick right back on. *It would just cycle on-off-on-off over and over and over all day long. *When I tried monting it on the inlet side it kicks on and stays on for quite a while, then shuts off for several minutes. *The engine temp stays nice and stable with the switch on the inlet too. *So for that particular set up the "feed forward" type of arrangement works best. *On my first build the radiator is smaller, it is mounted such that it gets plenty of natural air flow and the fan is small (stock bike fan). *On that one it works fine with the switch on the outlet side -- stable engine temps and "normal" fan operation. *Mounting the switch on the outlet is ore typical but either can work.

Cool, thanks for that info, i will try it on the inlet side then.I think it will work rather well....

Bug, for what it is worth:

My Honda CBR600 runs between 177 to 200 deg. F on cool days (75-80 deg. ambients) while keeping a minimum speed of 10-20mph. *If I stay idle for 5 min. or more, the fan kicks in at 220 deg everytime, faithfully (original radiator & fan assembly).

I noticed on days averaging 85+F, the fan cycles on and off a bit sooner, while in idle mode or low speed.
Keep the speed above 10-20mph and the fan remains off.

Gotta beleive the Gixxer comes close, and I know your running a bigger rad.

Bug the 01-03 GSXR 600 manual says that the stock thermostat begins to open at 180 F and should be fully open (full open = 0.31" lift) at 203 F. *It says that the stock fan switch kicks the fan on at 221 F and turns it back off at 212 F. *Tim

Just curious if the temperature switch location on the outlet/inlet worked best for you. I have a CBR600 with a civic radiator and was wondering which side might be best. I can always just try it on both sides but thought I would ask first. Thanks!

So the fan is running continuously? I heard they should run up at a certain temperature...

Not the same engine but the sensor on mine is installed on water pump inlet that signals a dash gauge. When connected to the harness auto off/on plus a dash switch will allow manual or automatic control.

The engine has a normal operating range as stated by Tim. That's where it should run - so a continuously running fan would be less efficient according to that rule.

Cooler seems good.
