Can I make my bike run a cooler temp

I like the way my bike runs when its cooler seems to kinda act up when its warmer. Was wodnering if theres a different thermostat I can get to keep it at a lower temp, I dont know what the operating temp is because its just a hot or cold gauge.

Re: Can I make my bike run a cooler temp

The thermostat is set to open and start flowing coolant when the engine is "warm".
The reason it gets hot is due to little or no airflow through the radiator at low speeds. The electric fan does not turn on until the engine gets warmer, and is designed to keep the engine from running hot. At normal riding speeds, the fan does not run.

Perhaps you could set the fan to turn on at a slightly lower temp?
I recommend that you do NOT install a lower temperature thermostat. This would cause the engine to run cold under normal riding conditions.

FYI - the temp gauge is not linear.

Get some good coolant, and some trublu oil stableizer..

Mine runs 10 deg c cooler with trublu!

Re: Can I make my bike run a cooler temp

You can also use a fluid called Water Wetter, that would help maintain a cooler temperature.

What actually happens when it is cooler? (I.e. power, running, idling etc)

If you mean the bike runs better before it reaches normal operating temp and then runs poorly there's something wrong with your mixture.
Instead of forcing the engine to operate below its designed optimum temperature you should sort your jetting out.

If you mean that it is running above the normal temp then you can try wrapping the headers as that gave me the single biggest drop in temperature I've ever had. I don't run a fan or coolant in my racebike so it tends to gain temperature very quickly when stationary.

Re: Can I make my bike run a cooler temp

I say add a toggle switch to where you can turn the fan off or on. The fan will come on when it is supposed to, but u can toggle it to where it can be turned on without reaching temp for it to do so on those hot days.

Re: Can I make my bike run a cooler temp

Im with bladeracer - if its not actually running over-hot, just running bad when hot, then you need to fix the running problem, not just reduce the temp.

Re: Can I make my bike run a cooler temp

It doesent run bad when Its at operating temp but I drag race it and its quicker when its cooler I dont know why. The only difference I can tell is that its hotter when at operating temp

Cooler/denser air?

There is a thread or two about a RAM-air intake. This might get around the hot air coming off the engine.

That's normal.
Cooler air is denser.
Have you shielded your airbox, float bowls and fuel tank from engine heat?

Re: Can I make my bike run a cooler temp

Yea I do after every run, I think I might put the fan on a toggle switch

I mean, have you fitted heat shields to keep engine heat away?
Hot fuel and air make less power.
