So… After 6 months of trial error I give up and turn to the people in this forum, I hope you can help me.. I love to drive my CPI, especially in the summer. Last year it destroyed my complete variomatics because of a loose screw. I just changed them then, roller still doesn’t start (had already started problems before). Then I changed the spark plug, again nothing. I changed the carburettor. After all the wrong attempts it also cost me the battery, so here also a new one built in (which is meanwhile also at the end of their days). Finally I checked whether because of the long duration maybe something is to be done in the petrol tap. so have sucked in the vacuum hose and it came without problems gasoline, heaven be thanks! I cleaned the air filter also once and sprayed the whole way again with brake cleaner. Funnyly he has by the brake cleaner which went into the carburettor at least as if it were ignite (for me the spark plugs and variomatik actually excludes) I am slowly with my Latin at the end. I guess it could lie on the newly installed carburettor. because after the installation two electric cranks hang loose and the carburettor mixes the oil itself, but what I already do in the tank. Also it could lie on the vacuum hose, which does not suck and therefore no petrol comes into the carburettor. But from here b I don’t really know a piece with scooters and have experienced and tried it all for a long time. If you have any questions about the parts just ask. Please help me!!!
