Dealing with engine heat on a Honda TRX 300

Recommended Posts

Just recently purchased a Honda TRX 300 and love everything about it except for the tremendous amount of heat that comes from the engine. Is there anything I can do to make this more bearable? Thanks.

get some heat wrap for the header. but since these are air cooled they run pretty hot

What are the chance that the heat wrap will cause problems for the engine?

the heat rap is a good idea but rapping it around the header wont be good.. wat it does is keeps the heat from escaping so if u rap it around the header it will just stop the heat from escaping in turn prohibit from cooling down which wud cause ur engine problems.. ahh is their one side that is hotter then the other? my guess is that the exhaust is throwing off the most of the heat because its closer to ur legs so u cud use the heat wrap and put it around the part of the exhaust that is close to ur leg, o and put it on the exhaust shield though dont apply it directly on the exhaust pipe.

There isn't really too much that you can do about the heat coming from the engine. It is air cooled, letting the heat radiate away from the motor is the only thing that keeps the motor from over heating.

An oil cooler is always a good idea for an air-cooled motor, it will increase the life expectancy of your motor and help protect against over heating. I don't know how much it will reduce the heat coming off of the motor, but it could help.

I'm going to step in here and correct you.

Wrapping any type of exhaust piping is a crucial and important step when controlling exhaust temperatures and reducing radiant heat by up to 50%. Keeping exhaust gases hotter within the exhaust system helps in decreasing density and increasing the flow of exhaust gases. This improves exhaust scavenging which, in turn, reduces intake temperatures for increased horsepower gains. Also, limiting the radiant heat trapped inside the engine bay decreases heat absorption through your legs.

Thanks for clearing things up bot def makes a lot more seance to me now

i didnt experience a lot of heat until i replaced the wimpy exhaust, rejetted the carb, oh and added the k&n .. there is a guy on ebay (or atleast he was when i bought mine) who has oil coolers already setup for the 300ex, its pretty nice, and seems to work pretty well too. all you have to do is remove the oil tube the feeds the head and replace it with the supplied tubing and hoses, it took me longer to figure out were i wanted to place the cooler itself then it did to plumb it in. and i would agree on wrapping the header (as in yes do it) but im not sure if i would bother with it if you are still running the stock setup , but that's just me .

      I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
      Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
      Sorry for my english
      Thank you

      Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?
