2000 honda trx90 fourtrax upgrades

[Aj Hurtibise]

Hey guys I'm new to the Forum I just got a 2000 Honda trx90 looking to make it go a little bit quicker I don't know much about four wheelers but I am a technician at a dealership so I know my way around a motor.

I have no affiliation or experience with these people but they have tons of go fast parts for the TRX90. http://www.mx-performance.com/id126.html

All depends on what kind of money your wanting to spend really. Exhaust and re jet will wake it up some.

@Lance Workman what kind of exhaust should i put on an what jets should I put on it. What other mods can i do. I want to keep it more for my self i am 20 an a smaller framed guy about 140ish. Probably look at spending 3-500 at the moment an continuing to upgrade over the summer an winter.

I have no personal experience with the trx90. But the Big Gun Evo is fairly priced not sure on jetting, I have had good luck with 6 sigma kits for other bikes and atvs.

TRX90 is about like most of the little honda motors.  Slip on exhaust, Rick's CDI, polish the head.  You can twist a little more power and a little more rev out of them but it's not going to be night and day.  It'll perk up a bit with a good tune up including carb clean and new NGK plug and slip on exhaust like Big Gun, FMF, etc.  You can also look into a size smaller rear tires to drop the gearing just a bit so you can pop the front up a little more.  They'll never really fly but they're fun anyway.  There is a whole market for the ATC70 as a toy like the TRX90.  Just fun to play with little bikes.

Really depends on how much money you want to spend.  There's even a 106CC big bore kit....

@MarkinAR ok what should i go for on the sprocket for the rear an front if u have a link that would help an same with the 106cc kit an other mods

[MarkinAR]

You'll just have google what you're looking for and read some reviews.  In ATV parts there are chinese junk parts, chinese decent parts, OEM, japanese aftermarket.  Quite a few options, just have to do a bit of legwork.  If it looks really cheap (like $60 for a cylinder, rings, piston and gaskets) stay away from it.  Same with consumable parts like chains and sprockets; there's a reason the pretty red chain is only $16.

I'm not that familiar with the 90 motors so I'd just Google and find a good performance site and do some reading.
