Derbi Atlantis 2002 : Yasuni C16

[oldgeek]

I found it on local CL and picked it up today. I did some research prior to the purchase, and I believe this one has the Piaggio motor. Only 375 miles on it, I paid $450. I had to borrow the money to get it, but it should be easy to make money selling this one, If I do not decide to keep it for myself.

Oh yes that's the Piggy motor alright. Nice score! I really like those Debi Atlantis'. careful not to fall in love haha!

Derbi's with the Piaggio motors are 2003 and newer just so's ya know.

1999-2002 have the Derbi/Morini motor
2003-2012 have the Piaggio motor

 That bad boy has the Piggy hanging off of it! The Spanish motor ones looked more like this:

Some 2002s have the Piaggo. I seem to remember reading that after around May 2002 the change over happened in the U. S. An identical model branded Piaggio was sold under the model name Deisis in the European market.

Be careful with the fragile cylinder studs. They are only 5mm in dia. 8 ft lb. max. I buggered one of mine and retapped all four for 6mm studs. I now have to drill out any new cylinder kits for the 6mm studs.

Also body plastic is somewhat aggravating. The brakes are pretty good. Hope you got the bigger PHVA 17.5 Dello. The PHVAs have vertically elongated slide valve openings for a more linear throttle action.

Looks like a great find to me.

Anyone who is familiar with these, know what's interchangeable with the front brake? A friend of mine has one and his front brake seals are going. He has not been able to track down the brake parts. Rather worrisome as its a 60+ mph bike.

Thanks for the heads up on the cylinder studs. I think I will keep it stock for now anyway.

I knew from my research there was a motor changeover at some point so I started looking at pictures of them and I decided the motor on this one LOOKED like a piggy. I decided to roll the dice. The owner had some hack work on it. Drywall screws holding most of the body panels on, the grab bar and the access cover in the seat box is missing. The autocock is gone and a brass fitting was jammed into the plastic tank outlet. The carb is not adjusted right there is a flat spot around 3/4 throttle and the airbox has been messed with. I think all minor stuff though. Pretty clean for a 14 year old scooter.

Easyparts.nl and oemmotorparts.com are good places for Derbi parts. If you you/he can't find parts then I have a caliper.

I did some more comparison and going by the exhaust flange on the cylinder it is definitely a piggy. There is an amazing selection of cylinders available in for this motor!

The Malossi iron cylinder 70cc kit is the one Mark runs in his.

Here's my Piggy Derbi Atlantis flip scoot. It shows the restriction I found in the carb. I also couldn't get the stock airbox to work out. I had to switch to a Minarelli airbox and upjet and it ran great after that!

Thanks for the reminder! I forgot about that one. Did you find any other restrictions besides that disc in the carb?

It cleaned up real well today, I got the carb acting a little better.

Not really. I think the stock exhaust is a restriction itself. I stole the huge Piggy rear pulley out of it and replaced it with a pre-bug/mina rear pulley and different belt so I don't even really know how fast a stock Atlantis can go. That one went pretty darned good for stock with a smaller pulley in it!
