Looks like that'll take some graft!

Look forward to seeing this happen.

Ore those bars original? They're very funky.

Well Al, it has two things going for it. It's Italian and it is red. Keep us posted! Love the idea of a 200.

Right on. Good luck. Here's the 2 Cagiva's I've built

The '83 (was sold in the US as 84's) can be tough because it doesn't share parts with the '85 and newer models. Luckily though they actually sold a decent amount of them and you can find parts. Let me know if you have any questions. If you're not already get on the Cagiva Facebook page....tons of guru's on there (mostly Italian) and lots of pictures and helpful info.

NIce Bikes! I'm finishing up a 1986 WMX125 now. I have a 1988 WMX125 I'll start soon.

I raced a 200 back in the day in cross country and hare scrambles, they would destroy anything else in it's class.

Few goodies I've picked up

Wow!

Cool stuff. Where did you get that pipe? Most of the 190 Cagiva pipes just looked like 125's with no turn out of the cylinder.

I built a cone pipe for my 125 but it's pretty crude...I'm still on the search for a good one or having one built.

I ran a WTB add over at the Swapmeet. A guy responded, he's had all of it in storage in his garage for 25+ years, everything but the frame. He said the pipe was a "Summers Racing Pipe". I blasted the pipe and my buddy ran a torch around the welds, then I clear coated. The engine is low hour.

Bunch more stuff on the way from Italy and Team Cagiva.

The only parts that will be a PITA are the spokes and the shock.

Yes sir!! The WMX200! And KTM thought they had an original idea with their 350. Cagiva beat them to it by about three decades!

Big Al...I was hoping you could help me out with a question. My WMX 125's cases were cracked and I got a set of NOS cases from Team Cagiva's Brian Catterson. I swapped everything over and it all went smooth......until I went to put the cylinder on and it didn't fit!!!

I'm wondering if I possibly got a set of 190 cases? The problem is that the cylinder stud spacing is different. The studs in the new cases are 95mm across and 84mm front to back. The old cases are 86mm across and 86mm front to back. The studs in the old cases are 37mm high(all four) and the new cases are 37mm high in front and 59mm in back.

I was hoping you could measure yours sometime and let me know what your dimensions are. I'm guessing I will be on the hunt for a 190 cylinder...which isn't a bad thing...but going to be more time and money.

Yep, you have 190 cases.

The 125 cases have the long rear stud. Did you rebuild the crank? I don't think 125 crank will work with 190 cylinder. Same rod but crank halves are different, plus pistons and rings for the 190 are unobtanium. I have several sets of NOS 190 cases.

Well im confused now. You say the 125 has the longer rear studs?

My stock 125 studs are all the same. On the new cases (that I suspect to be for a 190) the rear studs are higher. My 125 cylinder goes right on the old cases but will not on the new cases with the higher rear studs.

with my cheapy digital calipers i read center to center-

short studs - 95mm on rear, 90 mm on front, 85mm front to back

tall studs - 87mm rear, 90mm front, 85mm front to back

I could have flubbed a measurement though.

If you look at the picture of my 200 motor you can see the studs are all the same. A 200 base gasket will fit the short studded cases but not the long studded case. I googled some pics of the 83 WMX125 and it shows the long studs on the rear. I'll call by buddy and have him check his 83 WMX125 also.

Edit to add Info - 200 parts manual shows all the same numbers studs, 125 manual shows 2 different numbers.

Strange...I definitely have a 125 and my studs are all the same. So maybe there are 2 different cylinders that could of came on the 125?

How many cylinder studs for the head on yours?

Is the bike you're working on the one in the pic above?

when I zoom in on your pic above, it looks like the 125 has the taller studs on the rear?

never seen one or even a pic with the cylinder studs all the same size....?

Al,

You're absolutely right. I looked at pictures and looked up part numbers. The old cagiva mechanic who's working on my engine had the info crossed in his email.

I got nos 190 cases that were labeled with the 125 part number. Now I dont know what to do? I guess I need to find a set of usable 125 cases. You don't think I could use the 190 top end?

Wow.... What a project. I always wanted one of those back in the day.

How is it coming along? I imagine parts must be impossible to find.

Summers pipe? Would that be a 'Scott summers' pipe? I got to ride with Scott Summers in the 80's with a radical Ron turner 3 day lesson

That's what I was told. I guess they were sold as aftermarket? Also has a reed spacer.
