Beitrag oil leak and bad starting
hi i`m new in this forum.

my name is freddie smidt 42 years old and owner of a 2000 aprilia leonardo 150cc.

i think its a model 1 (96-98) because of the oldtype gasoline reservoire on the side of the frame.
i bought it while former owner did not use it very much and left it for 1,5 year.

cleaned the carb and oilflushed,new oil in it,new gasoline.

but it won`t start in the normal way.
it only will start if i start for about 30 sec. with throttle full open and then quickly shut it still pushing the startbutton.

another thing ,its leaking oil next to the oilfilter(i uploaded a picture)

plz help me out.

is the aprilia in general a bad scooter? because an seller of bikes told me so.

Hello Freddie,
my english is not the best (I use it too little), but I hope you'll understand what I want to say. :wink:

At first: The Aprilia Leonardo is not a bad scooter but sometimes a little diva. Some have no problems, some have them nearly every week. I think much of them are self made. There are some things to consider: regular inspection (oel, airbox, variator, cooling liquid, break fluid), maybe some small checks between the regular inspection and warm up the engine before starting "to race". But I think that's normal, also by other scooter manufacturer ... it's like every time ... some are better, some are totally garbage. Aprilia is (my point of view) in the first category.

Your starting problem sounds like a leak in the air supply. Take a look at the part number 16 --> http://www.easyparts-rollerteile.de/sho ... ilter.html A small leak at this part can be a reason for your problem. (Also the membrane in the carburettor).

And now I have a bad news for you ... maybe!? The hole, you have shown in your picture is a "leak hole". The oil you can see is a sign that one seal of the water pump is damaged. Is the liquid cooling liquid and not oil, then the seal on the other side is damaged. Both aren't good and should be repaired (as soon as possible).

Now you have to check:
- Do you have a Leo model built before 98 --> then you have to decompose the whole engine
- Do you have a Leo model built after 98 --> you can change the water pump without so much work

The repair parts are not so expensive, but the working time (for the Leo model <98). Maybe you are fit enough to repair it!? It's possible, but take some time (Leo model <98).

Best regards and I hope that helps a little bit
Hansejung

indeed part 16 was torn when i bought it,i ducktaped it so this will probably be the starting problem.
maybey toss the whole airfilter with a K&N filter(anyone tried this before?).
i find the airfilter is very complicated and restricted.

on paper it`s building year is 2000, but it has no fuelpump but a container like on easypart shown on the ealier models.
offcourse it can be switched by former users.

maybey in this forum i can find something which can tell me for sure whitch model it is.

thanks for swift reply.

Hello,
ducktape is not the best solution, but should work for a while. :D

I think a K&N filter will be without noticeable effect. Only some less money in your wallet.

To check your Leo typ, take a look into the following table:
http://aprilia-leonardo.de/html/fahrges ... erklaerung
or
--> at the Leo1 Mod. 98 I.M. D-E-F-G (Ident-Code) is the waterpump easy to repair

Best regard

Hello,
it does not matter. It is the same work and when you replace one seal, you also should / have to replace the second one.

With your starting problem:
Clean the carburettor and also the small air filter at the side of the carburettor. It is a small black rubber part.
The next point is, exchange the spark plug. Choose one like this one: http://www.louis.de/_30c6de326d5704eb20 ... r=10035100
The next you can try is this: http://www.louis.de/_30c6de326d5704eb20 ... r=10004878 a cleaner for the fuel system.

have a nice evening
Hansejung

Beitrag Re: oil leak and bad starting
thanks for all info.

i certantly will buy the iridium sparkplug,one told me when a sparkplug has been soaked in benzine you can put it in the trashcan, because the spark will never be good again.

i think i cleaned the carburator well, also used compressed air,i could see the little rubberaircleaner is little torn on ouside but looks its not leaking,but will excange it.

now the big part. "replace the seals".

if i keep refilling oil or close the hole prevent leaking will it damage the motor? it would be nice to repare it during winter,or will oil mix with coolingwater or visa versa.


i downloaded a manual, but not sure it is for a 1997 motor.

i read about a dvd with info about reparing the leonardo,is it downloadable ,i could donate using paypal.

I think that's not really correct.

Probably this is the wrong way. The leak hole should protect the engine against such situations. If you close the hole, the liquids could mix each other. And that's not good.

spend your money for other things and use this manual. If you have a question ask the people here in the forum.

Beitrag Re: oil leak and bad starting
old and new type ,i can see the seals are placed differant.

http://www.mijnalbum.nl/GroteFoto-HHDHV8IJ.jpg

in my case the seals were placed like in the new type crankcase,this must be a mistake and in this way it damaged the pumpblades.
can anyone confirm?

http://www.mijnalbum.nl/GroteFoto-M6PO4JR8.jpg

i think there`s less room if you place the seal in wrong place

Hello,
you have to put the seals with the "open" sides:
- to the pump wheel
- the other one you have to turn around 180°
Both seals have to be placed with the closed side to the leak hole.

have a nice day!
