Last weekend while cruising the Aprilia forum looking for info On my Beverly 250 I came across a guy in Charlottesville, VA. giving away a 150 Scarabeo. I dismissed it at first as a scam. But the guy posted more information so I decided to bite. Charlottesville is only 4 hours away and worst case I got a scoot to part out to ebay. He sent me pictures and the scoot looked to be in good shape. I did some research and found that these were built pre Piaggio's Aprilia buyout. The scoot has no limiters on it so you do need to watch the heat and not over rev them. They have a Rotax engine in them. They are said to be bullet proof. Parts are another thing., currently there is a 2001 parting out on ebay. They had all of the parts I need at the moment.
It has 5900 miles on it and the plastics looked good. I figured he would tell me if the left side was all missing or had road rash. He said that it had sat and he wanted it running again so he took it to the shop he bought it from to get it running. They did a complete fluid change and adjusted the valves (more on that later). He got it back and it wasn't as fast as it had been. He wanted them to fix that and they said they did all they could. meanwhile he had gotten a Burgman 400 and was happy with the power. So he gave up on the Scarabeo and just wanted it gone. It had a clean title and a new rear Dunlop K630 rear tire, new Gel battery and all new fluids and a few spider webs. I was so happy there were no bees because I hauled it home in my van.
I picked it up Thursday and got a beautiful preview of fall. I got it home and charged the battery. Its shoved up into the front and needs to be pulled out to get a cable on it:
I let the battery charge for a bit while I pulled some plastics from around the engine to get a look. The carb is shoved up under the air box and someone with a small hand can reach the idle screw. The A/F mixture is accessible but no treat. The gas smelled good and I figured the service would include a carb cleaning and if not it would be obvious. The battery had enough charge so I tried starting and nothing. The key is on, kill switch off, brake on, brake light on and starter button pressed and silence. Being the attentive person I am I then followed the steps and jumped the terminals on the relay and got sound. It was late and I was tired so I let the battery charge.
Last night I got the meter out and tested the starter switch, it was good. I then jumped the connector on the relay and nothing. I pulled the relay out and headed to Autozone. The guy there looked at it and pulled one from the back for a riding mower. It had all of the terminals and a relay is a relay off I go to put it in. I got it in and it started right up. The valves were making I slight clicking noise so they went on my list of things to check.
Today I pulled the plastics off of the back to clean it up a bit. I then pulled the under seat cover and the air box. two things these scoots are known for us damaged diaphragm's and carb slides that break off and head into the cylinders. I checked and both were good. Though you have access to the valve cover from a access port in the front you cant pull the cover without the air box being out of the way. The screws on the right side come in from the back of the scoot and the left side from the front. and none are easy to reach. I got the cover off and the valves were very tight. I didn't check to see what they were but set them to spec, .007 intake and .012 exhaust. With my limited 4 poke knowledge .007 and.012 seem big but its dead in the middle of Aprilias range. I think the shop didn't look at a manual but just did what you would do on any 150cc scoot. To get the scoot to TDC I pulled the CVT. It looked clean. Looking in the variator I did find it filled with grease:
This is the way they ship. The rollers are just starting to go flat so I'll replace them with sliders and clean the grease out. The variator is made by TGB and looks to be solid. The belt was in good shape but could be original so I'll replace that as well.
I got it back together enough to take a short trip up and down my street. This scoot handles nice but its acceleration is less than stellar. Tomorrow I'll get the rest together and ready for inspection on Monday.
I have worked on a few scooters from lots of manufactures and I will say this scoot is a big PITA. The starter relay is mounted behind the coolant bottle in the glove box. You have to take a lot off to get to the carb, no quick jet tuning there. Maybe as I work on it more I'll figure out short cuts but this is not a scooter for the newbie.
Here is a shot of the cleaned up back:
