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.

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 roughish Honda rancher TRX350TM3 and I am having trouble locating the vin number - I would like know year and specs as is it rough , it runs but has multiple little issues ( choke cable seems frozen , carb has sticky or ill adjusted float and leaks gas from bottom of carb , shut off valve needs new o-ring to stop leaking , ect)  just age and lack of maintenance issues , but I need to know what it is to get correct specs … I was told there would be a tag on front end of frame but I don't see one . Any help would be greatly appreciated .

      Hi, Guys. 
      Sorry for my English, I live in Ukrane, Kharkiv. 
      I have Can Am Renegede 800, 2007, g1, mileage is 430 hours. Happened issue with chain in first cylinder. Mechanic opened engine and found problems with piston, rings, cylinder, etc. So engine need full rebuild. 
      I found rebuild kit on ebay. https://www.ebay.com/itm/06-10-Can-Am-Outlander-800-800R-Stock-Cylinder-Crank-Complete-Engine-Rebuild-Kit/253868930525?fits=Make%3ACan-Am&hash=item3b1bc475dd:g:NdMAAOSwew5a-bY9
      Price is really good. For example original crankshaft costs $929.99. Here full kit costs $999. This kit made by BP Racing ATV Company. Here is their website https://bpracingatv.com/
      But I can’t find reviews to their products. My mechanics didn’t used parts from BP Racing ATV before. And their parts not very popular in Ukraine. I’m afraid that I will spent money for this kit + delivery + pay to mechanic for a work and will need new engine rebuild after 100 hours.
      What is the quality of parts from BP Racing ATV?
      Is it have sence to buy this kit, or pay more and buy original parts?
      Maybe someone used this kits for rebuild engine. And have expirence of using this parts. What will your mind about quality of parts from BP Racing?  
      Thanks for your answers.

      I bought a used 2017 Outty 1000r and have been hearing about folks melting plastics due to excessive heat near the pipe.
      It's winter here & I've been plowing my drive for a couple months without heat issues. I'd like any input if this will be a problem come summer?!?
      TIA

      I have a 2000 Arctic Cat 300 4 wheeler. I have been having some carburetor issues. So i bought a new carb. Now I'm having these issues. The unit will start and idle fine, when i go to accelerate it wants to cut off. So i checked to make sure it was getting gas and the fuel filter will be full of gas and then once the carb opens the filter drains down and will not refill quick enough to run. So i checked to make sure gas was flowing to the filter and it is flowing fine through the line. I remove the filter and run the gas line directly to the carb and the engine idle fine and then it will run good as i ride it for about 10 minutes then it will start with the same issues again i cannot accelerate enough to move the 4 wheeler. Every time i accelerate the unit will cut off. What is wrong with this thing. My 400 Arctic Cat is doing the same thing except it will backfire, I'm lost i have tried everything i know to do, what am i missing here. Thanks for your help

      I’m looking for new replacement shocks (front & rear.) on my 1997 Kawasaki Bayou 300 2x4. New OEM shocks are upwards of $400. I haven’t pulled the rims off to check the eyelet to eyelet length but I’m hoping an expert on this site does know( I called Kawasaki direct yesterday and they were of know help.) Any technical help would be appreciated. TY fellow members. Vic

      Hello, how are you'ns doing? I'm in the process of tearing my Kawasaki Bayou down to fix a rattling noise and an oil leak. I'll probably be asking questions about this project. My step-son has an Arctic Cat 300, he was riding yesterday and when he turned it off it was running fine, but it won't do anything. The lights come on but it won't turn over or anything. Does anyone have any ideas on what might be wrong? TIA
