Running again after rebuild, good to hear! Many ditech scooters stutter, it is not uncommon. If everything is good as new it shouldn't stutter, but slight unbalance in the crank can cause it and the higher the mileage the more it appears.

@knetterman I was a bit concerned at first that it sometimes dies/stutters for a brief moment, when accelerating, but all parts are in good condition, so I will probably leave it as is for now. It's running great otherwise. Thank you for your time and help.

@@EinarLerschen its very tricky. This is the second time I come across this. No fault codes were present, but injection did not work. Tested by hanging the injector loose on the bike to see the fuel spraying, after fitting a known working pump and injector from another scooter.

@@knetterman Okay, guess Ill have to look into the fuel pump, compressor and compression first for my problems. Mine starts instantly but dies after 1 second, this have to be done about 10 times to get it to idle. Sputters like hell around 5-7krpm but if one gets above that, it can be driven.

@@kees3056 wat Ali op die accus zet geloof ik niet. 10 km per Ali express accu, gok ik.

@@knetterman kom net terug van een ritje met een 100.000 mah accu en raad eens, 10,5 km totaal afgelegd en de laatste 1 km moest ik lopen dus omgerekend is het 100,- per 10 km op blauwe ali accu wat misschien klopt in een gemeten piek maar in realiteit behoorlijk misleidend uitvalt. Ik ga de mijne terugsturen en ze zoeken het maar uit daar. groet.

@@SEEvidz gaat Al paar duizend km goed met die scooter.💪💪💪

Hoe hard gaat ie van jou ​@@knetterman

@@SEEvidz Het is een bezorgscooter, gewoon 45.

Ho*

Don't own a fuel pressure gauge at the moment. Testing the fuel pressure can be done by checking if the injector sprays fuel when removing it and then crank the engine. This doesn't work if the regulator in the injector is bad. It regulates 2.5 bars. If fuel comes through I assume the pressure is higher than 2.5 bar. Also one could take a 2.5m fuel hose. Take the pump of scooter, put the pump on the floor and put the hang the hose 2.5 m up in the air and put 12 volts on it. If fuel comes out the top it should have 2.5 bar in theory.

@@knetterman That is some good reasoning, alltho I did purchases a fuel pressure gauge on mine already. Planning on putting the piaggio ditech sr on the road one day again. Mine has some serious cold starting issues. It starts always on the first crank and immediately dies after 1 second. I have to do this like 8 times and then it idles. Running is awful sputtering alltho it clears on certain rpm-range so one can squuese the acceleration atleast to some point but nowhere one could say it works.

Genau, kann immer besser!

@@sg_tuning You need Minarelli frame or make custom minarelli mounts, the morini mounts don't fit the minarelli. Minarelli engine Minarelli wiring loom You're better off finding a actual minarelli or try to fit a Piaggio engine, then you still need to cut off some of the frame to fit the subframe, and you need a Piaggio engine and wiring loom.

@@miha6917 hard to say from here, could be low compression.

@@knetterman is it possible that the winding is bad?

where can i contact you?

​@@miha6917 knettermantrades@gmail.com

@@knetterman i send you

I'd try 16*13, im not sure its either 16*13 or 15*12.

@@nicusecan7998 nope, only cleaning or swapping over components. There are one way valves in the housing that can leak and there is no way to repair this as I know of. It can cause low pressure because fuel can then circle inside the pump instead of pumping through. Also the small piston can wear or the seat of the crank rod can break. Can't find any new parts when that happens.....

@@knetterman Understood . And when you did the cleaning you make them function well again ? What solution do you use for cleaning them inside ? I Kno w that the acid winegar its good olso for carburetors cleaning

​@@nicusecan7998I use brake cleaner, or washing petrol. They don't always improve after cleaning, sometimes they are just worn.

@@knetterman I see. But another fuel pump from the cars it will run well? I never tryied this one

@@nicusecan7998 unlikely to work because it is designed especially for the injection system. Maybe with a pressure regulator from a car inline it could work, but still think the volume or pressure will be too low.

Is geen zip hè 😂😂😂😂😂

@@LucasLuisman-x3k neppe zip

Lastig, wat is je probleem??

@@knetterman als ik elektrische start doe gaat ie wel aan half maar hij start niet volledig waardoor ik niet kan rijden

De brandstofpomp is specifiek ontworpen voor het system, dat maakt het lastig. Weinig volume maar wel hoge druk, als ik het goed zeg. Heb eens een inline brandstofpomp van twee tientjes van een auto geprobeert, werkte niet ook al zou deze 2.5 bar kunnen leveren.

@@knetterman ik heb er nu eentje besteld die 3 bar moet kunnen doen,ik probeer het gewoon ff. De oude brandstofpomp doet het wel maar het plastic ringetje waar het asje in komt binnenin is afgeknapt helaas. Ik zie wel een pennetje zitten die je eruit kunt drukken maar dan moet er nog wat nieuws in komen,daar zijn vast geen onderdelen voor te vinden.

@@henrykreeft1208 Dat gat van het drijfstangetje van de pomp breekt makkelijk. Als je even een mailtje doet naar knettermantrades@gmail.com kan ik wel even kijken of ik nog een voor je heb. Kan wel even duren.

You may need to center the crank, use a center point on both ends and a hammer. Tap both sides and the crank should come loose.

I've never seen aftermarket cilinderkits that work for Ditech, it is always suitable for carb only even when it says Ditech. The Aftermarket cilinders can work, but the pistons don't. You need to make sure you have the original meteor 6131(could be 3161 I forget). 6 bars of air pressure is enough according to the manual(should be between 4-7 bar). It is important that the pressure stays/ doesn't drop, no leaks. Also CR8E never worked for me in the long run, try going back to CPR8E or Champion(I forget the number it's in a couple of videos)

​@@knettermanThank you for taking your time, I will definitely check the air compressor, the blue air injector with its seals and the teflon rings. Change the spark plug from CR8E to CPR8E, hopefully it will start.

I don't sell them unfortunately, they are hard to find. You'll have to get lucky. Sometimes they are on ebay marketplace.

Around 400.000 km.

It was clamped incorrectly, or there was a small crack in the line. I refitted the clamp, it wasn't fully on.

Volgende mij zat er weinig verschil tussen. Malossi trok iets sneller, en de Hebo had iets hogere top.

Zie het helaas vaak zat bij die 4t piaggio scooters. Distributie ketting is erg slap en verspringt vaak van tijd als die te slap word. Onderhoud is erg belangrijk.

@@ZipKroon als hij verspringt dat hoor je al.gewoon alles op tijd zetten en klaar.die kettingen kunnen wel wat aan zeker met 80 cc.vaak is dat nokkenas tandwiel die loskomt omdat die bout met ring onder niet goed gemonteerd en vast gezet.

Yes I have another video that shows it.

Morini has an DC ignition, Minarelli has an AC ignition. Different CDI, Different wiring loom. I used only the parts from a Minarelli, but the frame used to have a Morini subframe. I don't own this scooter anymore, but I'm restoring another SR50 with the Minarelli engine currently. I will upload more on that in a couple of weeks.

@@rensmekes4154 check bulb in cockpit

Ja, de juiste ECU startte hij wel weer mee.

Daar zijn ze voor heh. Het verbaast mij telkens weer dat hij maar blijft rijden.
