Hi Vlad...
Man...Sounds like you have no own CagivaClub in Serbia

Wooow... We are slowly becoming kind of international Club...aaaawwweeesome

It is pleasure for us as well... As you might know, Cagiva´s motorbikes have a lot of problems with their engines. There are plenty of issues where you can got to know where is the problem in, but for your pitty almost every issue is in Czech. Our languages are maybe a little bit similar, but only in a few cases. As you said before, it´s a big problem coz someone who can talk a lot about the problems can not speak english or whatever foering language. Some of our "Older" members as I think could speak russian, so maybe they can help you. My skills are not so suitable for your problem, but what I think is, you should check the mix of petrol and air in carburation system. Sometimes that is the main problem, coz if there is too much of petrol in the mixture, the engine is not able to fire it all and the same with the opossite way othervise you can small the petrol everywhere. The head of the engine might be smelled of petrol in the first couse. Yepp...Check this first out and then pay your attention to another parts. And also Vlad, I do not know if you have a good spark. Sometimes is that happening when you chose a wrong type of the spark. Check it up as well.
Now Im gonna translate your post for my czech non-english speaking mates...
Hele lidi, Vlado tady píše, že mu Canyon nejde nastartovat, když po denním ježdění chcípne motor. Já osobně si myslim, že má bud špatnou svíčku a nebo má špatně nastavenou směs v karburátoru. Tak nevim... Když tak sem něco napište a já bych mu to předatloval do angličtiny...
Díkes...
Vlad...Hope our mates will be so kind to write here something helpfull...
have a fun with your bike man...
Godzi...
