Thanks for having me.

Hello
New member to the site. Long time reader though. I bought my first trike this summer and have picked up a new winter project. I'm in the process of tearing down an old 83 200x basket case. The motor won't be salvageable so I'm going to make an auto x. This is primarily my reason for joining.
I've read it's best to use a larger rear sprocket. 45 teeth as opposed to the stock 40 tooth rear.
I'm having a lot of trouble trying to track anything down. All stores I find only have a 40 tooth rear.
The 83 200x has a 5 bolt rear sprocket, are there any sprockets from other atv's/bikes that will bolt up?
Any help would be greatly appreciated.
Thanks a lot

found this place makes larger sprockets for 200x here is a link to the page

hopefully someone who has an autox can shed light on the sprocket selection

That shop has great sprockets, good choice

Check with JMOOZY27 he is a member here, has a auto X and is a heck off a nice guy.

Use the 40 tooth on the rear and just install an 11 tooth on the front , same difference :lol:

Got the frame and swingarm blasted and primed this weekend. Rebuild the brake calipers. The front is good but the rear is a little messed up.

Hope that works. I guess the guy I bought it from who told me "the rear brake is air locked or something" didn't mention that he was using the piston as a brake.
My fault for not looking at it more closely. I couldn't find any spec. for the actual hight of the rear piston. I ground it down smooth and I believe it's now at 23mm. I'm using the ebrake adjuster bolt to stop the piston from moving in too far past the seal. I won't have my bike back together for a while so I'll have to wait and see if this will work...

The chain slider mounting bolts on the swing arm were stripped out so I drilled them out and welded two new nuts into their positions. Also plugged the two holes the guy left when he used machine screws to attach it.

Next days off I'm going to see what the temperature is like. May be able to get it painted...
Going to rebuild the forks with new wipers and seals. Figured I'd toss in some 3/4 inch lengths of PVC for some preload on the old springs.
Also I need to find some new blue fork boots.
Any suggestions/comments or help would be greatly appreciated as this is my first rebuild/resurrection.
Thanks guys

Well... She's ugly as hell. But she's done. And hopefully I can get a season out of her.
I didn't start this build as a restoration. More of a resurrection, when I bought this thing it was fried. Absolute trash ready for the scrap bin. I bought it to rebuild and ride and learn about the bike.
So, here's what's been done.
New fork seals and wipers.
New fork boots and grips.
Rebuilt front brake caliper and new Master cylinder.
New front, rear, swingarm and steering stem bearings.
Rebuilt rear brake caliper.
The engine was toast. Leaking oil... I can't begin to describe how bad it was. But it was gone.
I got ripped off trying to buy a good 200s motor.
When I opened it up the cylinder wall was cracked. Rings burnt down to nothin. And the valves were so badly burned they wouldn't close.
So what I have now is a Frankenstien engine.
185s bottom end, 200x jug and piston, cam came off a 200m, and the head is off a 200s.
I lapped some valves off a one of the engines I had and swapped them over. Had 150psi compression so I was happy with that.
Rebuilt the carb 6 times before she started purring. I think I'm finally ready to go riding!
I know some of you would turn their nose up at it. Cause it sure as hell ain't pretty. No matter to me. My next project I'll try to make something special. 229486

Looks fine to me. I built a 200X to run TT tracks here local and when I got done obsessing over everything looking new and shiny I ended up pissed at myself for being afraid to get it dirty. I rode it hard one weekend and it was scratched to Hades and back. If you build it to ride it, it will never look as good as the day you finished it. No reason to get too carried away on a rider. That 200X will be loads of fun whether its shiny or not.
