ok i no a little about 4 wheeler but not how to make them fast i got a 85 lt 230 all i have done so fare is got new black back rims, new hole shot tires, all new black plastic, all new barings and bushings , and a hmf pipe i had made for it, with a uni filter, for what it is i would say it moves but i am looking to go alot faster with out gitting a new 4 wheeler and i have been told there good bike but i dont no i have only had it for 2 weeks and i dont no alot about making power if any 1 can help me out on it i road a 450r and i no mine well not hang but if posable to get it close to the same speed thats my goal haha not posabel probley but i am going to try

 

 

If you have at least 2 to 3 years before you turn say...17 or so, weigh less than 165lbs, and do not have lots of skill and riding hours, then I say you have a great quad to fix up and 'get with it'. Your quad is old but there are lots of parts and 'hop ups' still out there for it. A 450r is a 60+ mph quad making roughly 50hp, yours will never match his performance and top speed. However, yours could match him in tight trails, tight tracks and very technical terrain.
I've ridden a LT230 before and after engine modification. More power was definitely made, but it wasn't magic. More power is only as useful as all other systems on the quad. More power with out good suspension, clutch, shift pawls, brakes and steering....sucks. A 450r is newer and therefore all systems work well.
Now that you have all new rubber, a pipe and a filter...
-adjust, lube or replace the cables - clutch, brake, compression release and throttle
-if clutching and shifting isn't solid and smooth, work on new clutch and pawls
-brakes should just plain work well from easy does it to panic stops
-the steering shouldn't bind or drag from full left to full right
-the suspension, there's a reason big money is spent here. The difference between suffering through various terrain and riding through various terrain is supension.
-finally, skill, that's where you come in. More riding time usually translates to more skill.

 

if you are looking for more speed go to a smaller rear sprocket and a larger front sprocket. I run a 14 tooth front and a 39 rear. You will lose a little torque for hill climbing but if yours is as strong as mine it won't matter with the granny gear in these things ( first gear).

 

You have to be the biggest dumbass i have ever seen in my life!A 450r doesnt even make 40 hp stock, and there is no way in hell the 230 is going to beat a 450 on the track trails or anywhere!!!!It will never happen unless it has an engine transplant or if it running a 300 stroker kit on alchohol or methane!!!!!!!The 230 is a super outdated quad that wont ever stand a chance with a 450 let alone a z400!Dont ever give false info to rookies like that you freakin retard!

 

i no it well never beat 1 i would like to stay kinda with it i am just look to get all the power i can out of it not trying to start no fights i need help full info like boring ect any 1 mess with the 230 that can tell me

 

Why dont you first try to write properly. I hate reading posts like yours that are one long sentence without using proper writing skills. At least make an attempt to at the very least.

Thanks,

Joe

Have you considered recalibrating the carb? With the new pipe and filter you may be runing to lean. It wont go far with a seized piston.
If your serious about "fast" the first thing I would do is be shure the suspension is up to the task. You cant be fast if your fighting your quad in every turn or whoop.
Then you can tackle the engine mods.

A pipe and filter are a good start, with the right carb jeting of course.
Wiseco sells a piston kit with a higher compression ratio than the stock. The kits can go all the way out to 2mm over.
I like to say, theres no replacement for displacement but compression is a good substitute.[img]i/expressions/face-icon-small-smile.gif[/img]

Web Cams may still offer a stage 1, 2 or 3 reweld, but im not shure. You may need new, stiffer, valve springs for the stage 2 or 3 grinds.

And there are a few companies that still offer the big bore kits. They take your stock cylinder, bore it out to accept a sleeve able to support a larger piston. madmanengineering is one example.

Glad to see you trying.
And dont mind some of the remarks you may get in these fourms, ive noticed some of these guys can be a little "overzealous" at times.

Good luck on the project and "keepemalive".

 

I agree with BigMc, get your suspension working good first. Nothing will get you thru the woods quicker & more comfortably.

If you really want to spend the $$, you can still get the big bore kit at http://madmanengineering.com and go to thumpertalk.coms store and you can still order a cam for it. You will need the Hp valve springs too.
