300EX need to be cooled!

[LdiBiTi300EX]

Hi guys I got a problem on my 300EX

Only after 2 minutes of riding my head cylinder come very like VERY hot and i dont trust that...I do the basic maintenance : change the oil and oil filter , cleaned the air filter. I got some old oil on my head cylinder and i know that will not help the engine to stay cold.

Do u guys know a good product to clean this stupid oil?

ThX!

I ran Motul 15w50 (I think) in mine & that made it run MUCH cooler!! But once I put my new piston in it started to run a little cooler too, the Motul is croch rocket oil & it is GOOD!!! BTW use a good degreaser on it & wash it up good!

Do a plug check too, if your lean it's going to run hot, and eventually cause damage, and im pretty sure you don't want that... If jetting isnt it look into some air scoops, huge difference in temps

Now my cylinder is clean and my quad is a little bit cooler

Sorry but whats lean means?
Need info about a plug check

Plug Check

Leaness is refering to your fuel mixture which you can find out by lookin around on the site, otherwise try running higher octane fuel, it would do the same thing as having richer jetting
