Aprilia Leonardo

Since this is my first post....Hi to you all! I am Andrej from Zagreb / Croatia and I own black 2000 Leo 150 with 12000 km.

Ihave one problem/question. I am having a problem with starting my Leo when it is "half warm". I must turn accerelator a little bit and if I let it go imediatley, motor turns off. So I must hold throtlle for a little bit after starting and then when i let it go , it`s idleing normaly.

The other problem is when i turn the throtlle, engine hesitates for a two-three seconds and then it goes. This is hapening allways, either cold or hot.

It seems to me like there is something wrong with carb and air/fuel distribution.

I am looking forward to see youre opinions.

Thanks!

Hi!

I don't know if i can help much, but...

Have you checked the air-tube coming before the air filter (the one with the wrinkles coming down from the air silencer beside the seat). When it's damaged, your Leo gets too much of air.

Perhaps the "throttle-closed-position" (running without gas) is too deep/small, so when its warm (no cold-engine auto choke), there's too little gas. Should run on about 1600 U/min. But this is only a guess...

Cheers to Zagreb

Ok, I`ll check

Thanks Mirko!
