I just got my first 250r. It is a bone stock 86 trx 250r. Except for fmf pipe and silencer & k&n filter.
What are the first things i should do to make it faster? Wich item's would produce the most power?

Please help me!!!!!!!!!

 

Get a hold of Eddie Sanders Racing.I have a 370PV Motor from them and am extremelly happy.

late,zubbeyboy ESR WEBSITE

 

I would go with

-reeds - I have V-force and love them
-carb - 38 mm AS
-pipe - My choice is ESR on pipes, but its your quad
-port/polish - mine was done by Trinity, came with quad when I bought it......seems to work great for me
-cr head gasket - ups compression

Im planning an ESR top end in the future......leaning toward 330pv as I am planning on 75% sand riding, and want reliability

It also depends on what riding you will be doing.

tune it and rip.......

My suggestion is, before you go all hog wild on making the motor faster, spend the money and time now on the suspension. A fast motor does you no good if you dont have the suspension to help you out. Trust me, I made this mistake and regret it. Get some shocks and maybe a-arms. Then sink money in the motor - reed cage, bigger carb, port and polished head.

 

I agree totally with untamedracer25!!!

LOL

 

Get that spelling right and you will be alright.

 

Here is a quick rundown of things to do to your quad in order from first to last:

1. nerf bars
2. kill switch
3. 18" rear tires, preferably on 8" wheels with bead locks
4. 19" front tires on offset wheels
5. extended rear axle
6. steering stabilizer
7. rear shock, PEP ZPS
8. front shocks, PEP ZPS
9. aluminum handle bars, Renthals, pick a bend you like. dont get the motorcycle bend, which is too low and forward for a quad.
10. Engine - pipe & silencer, larger carburetor then porting.

Take care of the handling first, then when you get the motor done you we be alot faster.

 

he is asking about power, not how to hook it up.

If your looking for more power, and on a budget you can shave your head for a little more torque, port the motor, put some decent reeds in it, get yourself a pipe, and you just picked yourself up 15-20horse.

Now do your tire and suspension mods [img]i/expressions/face-icon-small-smile.gif[/img]

 

I think we replied correctly [img]i/expressions/face-icon-small-happy.gif[/img]

I just purchased a bone stock 86 motor. It's got plenty of power. It's my suspention that makes it fast. PEP's [img]i/expressions/face-icon-small-wink.gif[/img]
As this dude's riding skills equall to the stock 250R's performance, he then will find the need for more power.
Please don't get me wrong, I love the high revs of my CGR 250cc cyl. And really love the awsome grunt of my CGR 310cc cyl. [img]i/expressions/face-icon-small-wink.gif[/img]
I rode and raced, all on the stock shocks. The good motors did virtually nothing for me, cept help me get beat-up.I finally got myself shocks. Biggest speed improvement that I've made.I can ride harder and longer now.

The turtle has PEP shocks~~ The rabbit a big fast motor...LOL

 

He may not have been asking about suspension, but we thought we would save him some time and physical torture and recommend the suspension first. The fastest motor does nothing if it wont hook up. We are just speaking from experience, and what we wish we would have done.
