Hi, i am new here, I was wondering if you can answer some of my questions:
1. How many pounds of pressure do i put in the tires front/rear(PSI)
2. I am looking to get an exhaust for my ATV, and I've heard you have to re-jet the carb, and something else. What will happen if i don't?
3. If anyone of you guys/girls, have any aftermarket parts for my ATV let me know.

Thankyou!

 

There is a plaque on the fender, that gives the recommended pressure if you are running the stock tires. Also can be found in the owner's manual. If you have aftermarket tires, you might start at around 4 psi and then go up and down a little and see what you like best.

A rejet changes the amount of fuel delivered in the carburator. The air/fuel ratio has to be kept at an ideal level. If there is to much fuel for the amount of air, the engine will run bad and dirty ("rich"), but you won't permanently damage the engine. If the amount of fuel is to little, the engine will run hot ("lean"), and you can literally melt your piston! So, when you add more air going in (opening up the airbox) or going out (performance muffler), you will be lean and requiring a rejet.

I would recommend an FMF PowerCore 4 muffler, and a few UNI 1" round vents in the airbox lid (if you don't run in the wet a lot)....and of course that rejet.

Jetting is as much art as it is science. If you aren't up to it, have it done by an experienced pro. http://www.dansmc.com/carbs2.htm

 

Thanks so much, youve been very helpful, reconranger, and what if i just a put a slip on exhaust on there. do i still have to re-jet the carb? If so, how much do you think the unit and re-jeting the carb in total will cost. Thanks

 

hi again reconranger. i am also looking to buy Trail Tech Vapor Speedometer Tachometer Computer Honda TRX 250EX TRX250EX 01-06. is that hard to instal? i want to take it to a ATV place. i just dont know how much dough its going to cost.

 

You will still need to rejet with the slip-on for the same reasons Recon mentioned above. Also, get a better air filter. UNI makes a good one.

Typically you will be looking at $60 to $75 an hour for a shop mechanic to do anything, and I will bet money it won't be under 3 hours for a dealer to install it for you (hope I'm wrong)

 

and how much $ do you think it will be to instal a Trail Tech Vapor Speedometer Tachometer Computer Honda TRX 250EX 2001-2006?

 

Your best bet is to call the dealership to find out
