200x forks on 250sx

[Bo0YaA]

Ok so i have been thinking about putting the 200x forks on my sx and I was wondering, would I use the whole triple tree and just bolt it on? Or would i just use the 250sx triple and push the 200x shocks through? If its easier to use the 200x triple and everything will the 250sx light still work or will I have to buy the 200x light?

Just wondering lol

thanks guys

That will be dictated by which front tire you use. Right now I'm fitting my SX with a 350X front end and so far everything looks as if it's going to work just fine. The only consideration is if the 200X uses the same width tire and rim as the 250SX. Personally, I'm don' know but it's something to look in to.

You can simply slide the 200X legs in the SX triples and gain better suspension and run a disc brake. But you won't have the extra bolts holding the legs in and the aluminum lower triple that the 200X triples offer.

Or you can use an entire front end from a 200X,250R or 350X as long as you use the triples. BUT, each one of these will require the cutting of the stock 250SX steering stop boss on the frame and the fabrication or addition of the stock mating steering stop to whatever model front end you use. This requires decent fab and welding skills and takes a few hours.

Last is the headlight.... ANY one of those headlights will run off of the stock SX plug. You have to modify the plug on the light with 1/4" spade wireless connectors, rubber straps get spun around or the stock SX light holder gets scrapped. One way or another, they all work on the SX with ease.

[Bo0YaA]

So would I be able to use the smaller tire if I just use the 200x legs on the 250sx tree.

[FlyingW]

I already delt with those issues on my SX. As a matter of fact, I bought a wire feed welder yesterday and welded a stop on the neck of the frame as the 350X has and I simply cut the plug off the SX light assy and installed it on the 350X light assembly.

As for the front end, I put the entire 350X front end on - triples, forks, wheel assy, and brake. I just had to slide the fork tube up in to the trees about 1.5". I'll fine tune it when when I get it back on its wheels.

Bo0, remember, the SX has a wide tire assy so the triples are wide to accomodate that so if you put the 200X forks in the SX trees you still have to deal with the wide spread of the forks. What I don't know is, does the 200X have a wide front tire assy as the 250SX? I've never owned a 200X. One thing I'm sure of is my SX should handle better with the narrow front tire on it plus the handle bars are raked back just a bit but it's going to be a cruiser so no big.

Hey FW, Looking good!! Whatdgya get for a welder? I have a Lincoln SP175PLUS with gas and it works awesome...

BOO - Anyhow, you can also run ANY tire, wheel and hub combo but they are all different...

The axle spaces may have to be changed or swapped. I think it's 3/8 black pipe that can enhance your spacer. And the caliper bracket may require 3 washers and a longer bolt but they all can be used.

This is why it's best to buy a whole front end complete and not nickel and dime yourself to death.

I like the skinny tires much better, the SX is a new machine with the different front end.......

[FlyingW]

I bought a Schumacher gas/gasless 90amp for 198.00 at one of the local discount tool stores. I agree with you in that Bo0 should do the entire front end to eliminate screwing around with spacers and brackets. Mine bolted right up. No fuss, no muss.

[Bo0YaA]

Forgive my noobness, I have no idea what the steering stop boss is lol. Perhaps I should just sell the sx and get a 350x lol other then I really like the reverse and electric start.

[Bo0YaA]

BTW FlyingW,

Thats what I was hoping to do to mine, Looks awesome

[FlyingW]

Here's the stop boss. It's nothing more than a 1" x 1/2" piece of 1/4" mild steel. I can cut you one out and mail it to you. All you have to do is find someone to weld it on. The SX is a great all around machine. I put an electric starter on my 350 but I wish it had reverse. I'd keep the SX.

[FlyingW]

You are correct in that the 350X front end bolt right up. The stop boss is the only thing to add to keep your forks from bashing in the tank when the forks go hard over. As I said before, the 350X forks have to be slid up the trees about 1.5-2" to get the front end ride height right.

[Bo0YaA]

Ok, so let me get this straight. There is a stop boss on the sx already that will have to be removed in-order for the 350x or 200x forks just to bolt on. Then I will need to reattach a new stop boss as to keep the forks out of my tank....Right? lol

I appreciate all the effort you are putting forth in explaining this to me....Much more helpful then some of the other forums I have been to in the past.

[FlyingW]

Well, on my 86SX I didn't have to remove the old stop boss because the SX uses the frame just behind the neck as the stop boss but the 350X has the boss on the neck so all I did was weld the new boss on, nothing to remove on the old boss. As you can see in the pics above, the 350X has the stop blocks that stick up on the lower tree. The 250X uses a different configuration which does not interfer with the 350X front end. Weld on the new boss in the center of the neck about 3/8" above the lower tree and your done.

[Bo0YaA]

Thanks a ton man, you have gone out of your way to explain this and I really appreciate it.

I think i can actually handle it now seeing what you have shown me.

[FlyingW]

You're welcome my friend. That's why we're here. If I can do anything else to help just let me know.

Jim

[wild200x]

great job FlyingW! this is an exelent example of why we are here for each other.
and i will be doing this mod myself to our sx. this post has helped me through it in advance. thank you!

[FlyingW]

You guys are too kind. I do believe in tapping available resources and this forum is the best for 3 wheeler info. I have gotten tons of useful info off this site since I signed up. You all are a good bunch of guys and girls and I appreciate all of you who post.

:hail: awesome attitude man!:hail:

[Bo0YaA]

Ok well I bought everything I needed tonight, got a whole 85 200x front end minus the fender. But i just have a couple more questions. I asked earlier about the light and what I ment was is the width of the upper forks such that the 250sx light will still mount up ok? and will the 350x light mount to the 200x forks? also, what about the dash mounting to the triple of the 200x?

[Rex Karz]

Word is that the lighter and higher front end makes handling go in the dumper. Seems to me that the trike becomes quite unbalanced. What say you?

Lol sounds like a trike! :hail:

[FlyingW]

200X can probably answer that question better than I can but I know the 250SX has a real wide spread to accomodate the wide tire so if the 200X has a narrow tire like the 350X then you can use the 200X or 350X light. You'll just have to clip the plug off the 250SX light and splice it on to whatever light you use. As for the dash, just use the 250SX handlebar clamps on the 200X upper triple tree as the dash mounts to the little ears on the handle bar clamps. The hole spacing on the clamps were pretty much the same across many years and models.

[Bo0YaA]

Word is that the lighter and higher front end makes handling go in the dumper. Seems to me that the trike becomes quite unbalanced. What say you? Well Ill let you know once im done with it. However, a 22x11x8 front tire isnt the greatest handling front tire so I dont see how it can get any worse.

[FlyingW]

Ya, that's why I'm redoing mine. What were they thinking????

Yes, they ALL mount... I forget which conversion it was but one of them I had to flip the rubber straps around so that they weren't so stretched out and although they were backwards, it worked great.

As for the dash, just use the top part of the clamps from your SX on the 200X top triple and you can run the key switch and R?N light.....

That 85 200X uses a whole differnt stop than FW's pics. You need to either grab a 200X neck and cut the stop off or make 2 custom side stops like I did. It's simple, just cut stuff out of cardboard fist, then make it from metal.

As for welding..... This is what worked for me and I've done 4 conversions now.... Knock out that lower race before welding, it is hardened and I don't like the idea of heating it up when welding. I have old used races that I knock in there, not fully seated. Just deep enough that it keeps the area round where your heat is concentrated when welding. I use a mig welder and weld it up. Then I let it cool and later I warm it all up with an oxy/acet to get everything happy and round again. I have gotten away without the torch but without that race in there you chance not being able to get the race back in there after welding, the neck does get distorted. Then I tap out my crap race and "pull" in the old one with a 1/2-13 threaded rod and some big washers. Paint it up and your done.

Sounds like more than it is, problem is I have seen guys crack races or beat the snot out of them to get them back in after welding and thats when I started using the above method and the last 3 I did were a piece of cake.....

Well, I spent $250.00 buying all the parts I needed and to be honest Im having 2nd thoughts lol. I read alot about how light it makes the front end and to be honest, with all the other mods Im getting ready to do, it makes me nervous. Im buying a fmf power core 4 pipe, I already bought the 350x carb and uni filter and thinking $120.00 isnt bad for a webcam (bolt in). I do alot of moutain type climbing up steep grades and I dont want this thing to flip over on me..... What if I put a smaller tire on the front like this one http://www.online-motorcycle-parts.com/atv_parts/atv_tire/goodyear_att902_22x9x8_tire/goodyear_att902_22x9x8_tire.shtml first of all would it fit?? and if it would I cant help but think that it would improve handling. UGGGGGG I dont know what to do lol its not like Im jumping alot so I dont really need the extra suspension but I really do like the looks.

Im so confused.........Help me Obi-Wan your my only hope

[FlyingW]

Awwww man, don't fold on us now. likestrikes has done this mod and he's the subject matter expert on this mod. Use his knowledge to your advantage. Come on man, get crackin.

Are you kidding?????

My SX has an aftermarket exhaust, no AB lid, High comp piston 2mm over, Webcam, racing valve springs, 350X carb, 200X front end, 350X headlight, 250R front fender, 250R gold all around and a couple I'm missing.

IT'S STILL A 250SX!!!!!! A lighter 200X with a pipe and open box will still beat it I'm sure. The SX is limited by the gearing!!

It rips when you want it to.... But at least it HAS the power to make it up a hill.....

More power means a different riding style or, lean forwards a bit more over the bars on steep inclines. But, you'll find that you CAN now climb steeper inclines.

It's a 4 stroke, it's not gonna rip you arms out of your socket. I'm very use to my 350X now and it' like throwing around a bicycle.... I gotta get a vid corder to show some action on my mX track........

[FlyingW]

Mine is basically stock and I only got to ride if a short distance before pullingit in to rip it apart. I'm anxious to see how it does with the 350 front end on it. The SX is more of a work horse than a sport trike so it needs to be ridden accordingly. They weren't designed for hot dogging but I know it's still going to be a good ride.

[madmax]

Boo, if you do it, you'll probably like it.
I did the 200X front on my SX and it worked fine. It was no more prone to wheelie than it was before the conversion. The handling is improved also... disc brake is a big plus.. will make you wish you had one on the rear axle.

[SYKOLINCOLN]

hey booya need a 200x front end? I have a complete one! forks,tripples, wheel,tire caliper,disc,hub, line (will need handle bars and front brake master cyl) and you will need a headlight setup and fender might I sugest a 85-86 250r headlight and fender, that would look sweet!! I'll do $125 shipped to your dore homie! pics of it in 3ww classified section.
