Just got a Aprilia SR50 DiTech, already named it "The Crazy Ape" ;D! Im pretty excited, i never thought i would get the chance to get one. I got really lucky and got a good deal on this one. Its kinda rough around the edges with some hard miles but with some TLC i will get it back in sweet order  . Here are some pics of it just how i picked it up today.      |

I'm so jealous. Fuel injected and water cooled. That is one sweet ride.

Thanks guys ;D. Its wanna those once in a lifetime deals for me. Shifty, i traded my 86 Polaris Indy400 snowmobile that i had been trying to sell for 2 years now  . In fact if it werent for friend saying "tell me you contacted them about that", I might have totally missed the deal. I never really thought the guy would trade for my sled, but after a little push i figured what the hell, never hurts to ask. long story short, it worked out great! The Aprilia wont even start and im still stoked  . Gonna look into it tomorrow |

No kiddin, i cant even find a spark plug lol. It keeps soaking the plug. I can pull it out and it fires good, but as soon as it fires, it floods. Im thinking the crank case has got allot of fuel in it from trying to start it while flooded (who knows how much it was cranked on)? I unplugged the injector and it started and ran for a few seconds. Plugged the injector back in and it flooded again. I felt like i was waisting time with this plug so i went o the hunt for a new one with no luck. Thats as far as i have gotten. I need to read up on these things  |

Thanks Brent  . I have been reading about this thing and common problems with the Morini DiTechs fro about two hours. Found some interesting stuff... Injector problems, air pump problems, both of those seem to need attention weather its the problem or not. Seems moisture from the air pumps causes trouble. And people have reported faulty injectors and injector seals. All these can cause starting problems. Now i have a place to start but dont feel like, or have the room to work on it right now. Gonna get a game boy tuner and diagnostic set-up first and go from there....All i really want to do for now is get it running smooth so i can ride it instead of Skeedr for awhile. Im not really worried about mods....Yet |

Found some time to work on the Ape today. I started off by running a self diagnostic scan on the ecu. To do this on the year i have you just hold the throttle at the WOT position with the (motor) key off and the kill switch in the run position. With the throttle wide open turn the ignition on, the fuel injector light should come on for two seconds while the fuel pump primes, then the light should go off then come right back on. As soon as the fuel injector light comes back on you release the throttle and if all went right you should see the injector light start to flash if there are any error codes in the ecu. Mine had 14 error codes stored in the ecu . Most were probably chain reactions from me and maybe others unplugging the injector and starting it. Other codes seem to need attention. Like water in the air line and error in air injector codes. This seems to be a big problem with ditechs, and is most likely the reason mine wont run. I will be taking the air pump off and cleaning the injector and all the components tomorrow. All take pics  . The good news is the ecu is working proper and all the codes cleared. You do this by simply letting the codes cycle themselves four times. I just ended up taking a break while they cleared themselves up. The biggest thing is making sure to clear all codes after fixing any problems, they dont clear themselves. These error codes could have been stored for years as far as i know . Thats were the gameboy is gonna come in handy. I will know the whole history of the motor then . Hopefully this little factory code access trick will help anybody looking at used ditechs |

A dealer friend of mine was telling me about the water that accumulates in the air line. His solution was to use a (not sure what to call it) water catch made of some sort of filter. Similar he said to the ones that you use on your air compressor just smaller.
Very good research your officially the first guy to get into the fuel injection stuff that I know of around these parts.

Thanks Jeremy. From what i have read so far the moisture in the air pump seems to be one of the biggest problems with these. There are a few ways to solve this problem, one being(most common) a in line dryer, or moisture trap. Like you said, same theory as we use on our air compressors. I guess some Aprilia dealers even put them in for you to avoid problems. To bad they didnt figure that out at the factory before they shipped em out  . Makes total sense, the heat from the motor combined with cold moist air is bound to cause condensation and get water in the injection system. Mine is totally stock w/out any type of air dryer so im sure its nasty in there  . Oh, another thing i noticed was that my speedo cable was unhooked  . It hard telling how many miles are on this thing? Good thing is the cable was fine so i plugged it back in . O,well i knew this thing was hiding 8 years of bad ownership and "ride hard, put away wet" type of abuse . No big deal to me, im just glad someone like me got it. Now it will get a second chance to be a nice ride with a proud owner. Not just another "moped" like most people see any scooter out there |

Good info. Just curious, will the Aprilia do key on engine running diagnostics as well or only the method you described? It's a shame they didn't just make it an OBD II setup so you could buy a scanner or take it to Autozone and make them plug it in for free. This is kinda like OBD I, and I was never a fan of sitting in the car counting flashes and pauses on a check engine light then digging up what these codes mean. Then again, it beats what my scooter tells me when it has trouble... nothing.  |

I pretty sure this is the only diagnostics you can do w/out any tools. I too am not too fond of the ole count the flashes fifteen hundred times. I let all 14 codes cycle twice to make sure i had them right, then i walked into the house for a break while they cleared themselves. With a gameboy on the other hand, you can do allot more. Running diagnostics, engine hours, and so on. My biggest WOW about these things is that they are capable of 120 miles out of a gallon of gas with the injection. Now i can defiantly get used to that on a 2T. Even 100 or 80 miles to a gallon with the power of a 2T is the bees knees in my book . |
