1983 ATC200X basket case resto-mod

Yes 100% correct, just reverse the bracket, it sticks out a bit so I presume it was like this to make it more compact for storage etc, I put pictures these up as I thought it gave a clear image of the tank scoop mounts look like.

No that's a kx112 Eric gorr motor. It's not a friendly swap, and 1st gen 200xs are pointless to do any 2 stroke swap in...no a blaster motor won't fit. I own blasters too. The frame design does not lend to 2 strokes with center pipe swaps nice....let alone linking airboxes to carbs. I built that one from spares also.

With enough time and money you can make anything work. With that said, the more you chop up the frame and modify these bikes the more you lose what makes the 200X so much fun. Solid reliable, lightweight, balanced and great handling. I’ve cut frames in half to swap street bike engines into dual sport frames and that didn’t bother me a bit because the frames are plentiful and easy to come by, plus the bike was as turd out of the box (400lbs and 37hp is not an exhilarating ride). I can’t bring myself to hack this 200X up. Some basic, minor improvements to keep it going as a real rider for many more years is my goal. Having OEM parts availability is a huge plus too as far as the engine goes. With that said, when your Gorr built Kawi/Honda hybrid hits the power and I bet it’s a load of fun. ��

Yes it ran....it was a pit the gearing it. Tha'ts your main problem when doing dirt-bike swaps. Things are engineered for a reason. I hated that machine. I road it 2 or 3 times and traded it on a 660 raptor. Let a 200x alone, you need more buy a 250r or a 350x

Looking forward to getting this tank sorted out, are there any petcock rebuild kits available? I see all balls makes a kit for the other 200cc ATC’s, but not the 200X. I’m thinking about buying the basic ATC200 kit and using the pillow out of it in my stock petcock.

any tank used stock petcocks which every Chinese guy remakes now days for a few bucks. You are way over thinking the petcock issue which is no issue. Run an inline fuel filter and call it a day. Just not a paper one. Ethanol will eat the paper in 2-3 years.

I’ve seen the Chinese options, I will stick with my Honda casting. I’ll probably gut a Chinese one and rebuild mine. I just don’t want it to leak fuel!

I have been through this petcock issue so many time. Honda ,suzuki, yamaha it does not matter. All of the petcocks fail after 5 to 12 years. Just get the cheap ($15) ebay petcock and go ride. I usually keep a new spare because the same one will fit so many models. It is much easier to get right than the weird petcock set up that is on the ATC 70, 110, & 125M. i am completely fed up with trying to get those to not leak.

[oldskool83]

Honda didnt make their own castings lol...there is nothing wrong with a chineese petcock. I use them on everything. 20 years ago maybe they were total garbage but stuff has been getting better. I've had no issues with any of mine. Waste you money in other areas such as suspension OR real foot pegs

[1stGEN110]

Sounds like the verdict is in! Chinese petcock it is!

Been away from the forums for awhile, my first child was born Wednesday! As I am laying low around the house for the most part tending to her and my wife, I’ve been researching carb options. As a fallback, I have my stock 200X carb to use which I’m sure would make good torque down low on the 230 motor. I’m debating trying to fit a TM28 pumper or even a Yoshimura MJN28 carb on it. Easiest would be the 200X 24mm Kiehin, but what’s the fun in that?! I’ll need to get the motor in the frame along with a manifold and see what kind of clearance I have. Most, if not all, flatslide carbs have wide bodies.

Congrats on your baby!

Congrats on your baby!

Thank you sir! She’s our first, momma was admitted to the hospital last night with a severe kidney infection so it’s going to be me and the little one for awhile. My life has been a series of “trials by fire” basically a single Dad less than a week after delivery, it could be worse!

After doing some additional research (as you know I have plenty of idle time on my hands) it looks like I might pickup a couple MPH top speed with the bigger carb but since I’m aiming for a trail rider with plenty of grunt I think I’ll stick with the stock 200X carb for now, if I good deal pops up I may swing for an XR200 26mm carb, that should meet in the middle!

In my opinion, the 200X carb would probably be the best for a trail rider. When swapped the 200X carb out for a XR200 carb on my AutoX, I lost a little bit on the bottom end and gained a little bit on the top end. It does rev out better now, but most people probably couldn't tell the difference. For me anyway, I want better bottom end power for a trail rider.

Got access to the tools to measure the runout on my original axle today. She’s got over 3/16” of runout!!! Wow! I’ll be contacting DURABLUE tomorrow for a replacement axle. I also found that my forks have a very slight amount of bend to them, a straightedge from the top of the chrome to the fork seal area shows less than a 1/16” gap in the middle of the span. I’ll run them for now to get it going but definitely plan to explore other options down the road.

I just watched a video of a guy who has used modern dual sports to make trike conversions that are street legal… man that has me thinking hard about plating this bike. No aspirations to take trips or go on the interstate but it would be awesome to cruise through town on a 230X!!! Pull up to Dairy Queen on a Friday night on my three wheeler… decisions
