I recently purchased a 300ex and noticed its only air cooled and the things HOT. There are no performance upgrades to it other than a UNA filter. I see people are cutting into the oil line. But i cant seem to find this oil line. Im not sure if its overheating or not but i do ride it pretty hard. Any help would be great. Also i cant get the starter button to work. all ive been doing is jumping the solonoid to get it to fire. Its working but want to fix it.

My 250X is the same way....its hot too

Find out what the Running temp is and what it should be and go from there.

I have an oil cooler on my 250x and it still runs HOT.

Cut the line on the right crankcase cover that runs to the head. Its a steel tube, hook some rubber hose up to it and get a heat exchanger and mount it to the frame.

I use mobil 1 v-twin oil. Harley guys with temp sticks say it decreases engine temps about 10 degrees.

How do you know?

My 400ex runs hot

 

[mud99]

I used a infared thamomater

 

[tomgodd]

What temp does it run at? I thought my sons Dirtbike was running warm and I checked his and found it was a normal running temp.

 

[tomgodd]

Do you know what temp it should be running?

i dont like oil coolers and my friend blow his up when he ran one so i run my hard and faster you go the beeter it runs

 

[Redracer]

the oil cooler didn't blow it up, it was either installed wrong or he didn't put more oil in to compensate for the larger capacity.

 

[300ex power by monster]

it was instaled wrong but i pussh my bike hard and it say cool cuz it gets more air

 

[Redracer]

The air cooled engine is more reliable. Look at the 400EX. that engine has been the same since the XR400 came out.
