Try sliding the monorail either up or down "depending where it is now".

Hmm, that's what i did and it seemed to have solved the issue. I've only had it happened once though, and when it happened, i searched for a thread and seen someone reply about moving the monorail. Maybe loosen up the screw that holds the ramp and move the ramp a lil bit. I notice the ball speed can very on the monorail, so maybe that just happens sometimes, but if it's happening often, then there's definitely an alignment issue somewhere.

That's funny because this has happened to some extent on probably every TSPP I have played on location.

Does it happen often, or is it random? I've had the pinball jump over my flippers a cpl times, the pinball can do funny things at times I love this machine.

My game also had this issue, although I've played plenty that didn't. I suspect there were different runs of wireforms done as there were different runs of the game made. I never found anyone locally who had one to compare the bends in the wireform before I eventually sold the game.

What helped some was adding washers on the top hex post where the top of the wireform mounts (below the ramp mounting point). Elevating the monorail ramp even slightly will slow the ball down. Also make sure the three thumbscrews holding down the upper playfield are real tight. Added height there will add speed on the monorail ramp.

I've never had this happen in a year of play. I get the rare airball landing on the monorail though, that's always cool . I just double checked what mine is like going down the monorail - I notice the ball goes nice and slow down the monorail but then speeds up pretty good it the big drop off in the wireform. Hard to tell from your video but it looks like the ball is going a lot faster when it leaves your monorail and gets in to the wireform.

Only easy fix I can think of is that maybe your game is set up too steep? Or maybe out of level sloping down to the right? The other suggestions already made sound good too.

exactly my thoughts, what is the pitch of the game?. My ball doesn't appear to move that fast across the monorail into the wireform.

I get the exact same problem, if its a slower ball its fine but any speed and bye bye ball!!

I did a slight bend and its quite a bit better, I am thinking of adding 'something' to the bend to stop this.

I also have had the problem. It seems to be more when you miss a shot from the top right flipper on the upper playfield so the ball travels down the monorail with more speed and spin.
My solution was to attach a small figure (about 2 inches tall) of Mr Burns on to the one way gate from the plunger. Not only did this mean that on the occasions when the ball did look like it was going to bounce off the rail it clipped the figure and stayed on the rail, it was also a mod fitting in with the rest of the table.

You need to bend up the right side so it doesn't jump off. I did this on the left ramp on LOTR. You unmount it and slightly bend the mounting areas so it won't lean to the right like it does right now.

I haven't done this, but by looking at the wire ramp, wouldn't bending the mount up make things worse? Seems like it would make it lean more to the right and also make the monorail more steep. I think it might need to be bent down, but I could be wrong since i haven't tried. Seems like that would push the wire ramp over to the right though, so the monorail might not line up properly, i dunno.

Up on one side is the same as down on the other. It depends on which was you bend it.

My monorail ball does not travel that fast---ever. Makes me think the angle of your playfield is too steep, or the monorail is.

Adjust/re-tighten the metal habitrail where it attaches to the post by Itchy & Scratchy. Try to push it "to the left" as much as possible so that when you tighten the screw, the metal "loop" between the washers is flush against it.

just bend it up

Turn the middle side topwise. Topwise!

you need to perfectly match the contours of the human verti-brains

one, two, better not sue!

I have aligned it better by loosening the screw that holds down the right side of the monorail and even have tried a small spacer and longer screw to lessen it's pitch. I hope this helps.

Gah! I've had this game for a week and as of yesterday every trip down the monorail jumps off into the right outlane. It's ridiculous!

Plenty of suggestions in this thread on how to fix this.

Very good

Hrmmm, maybe try adding a few washers under where the habitrail mounts over by itchy and scratchy so that the monorail is less "steep"

good luck!!

I cant believe that pinball is so awesome and funny at the same time. Do'H!!

A thick coat of Vaseline on the monorail oughta do the trick...
