issues with my yamaha YT125 .. Ok here is whats bugging me about this trike , it will start (when it wants to) but will die after a few seconds sometimes i can ride it for about a minute before it starts bogging down and die .. Every time the this happens the plug is wet , I checked it for leaks on the seals but nothing ,, the compression is just over 90psi and running 40 to 1 on premix (removed the oil pump system ) .. Now the carburetor seems to be adjusted right but sometimes runs great and sometimes it sucks ..lots of smoke out of the exhaust , lots .. scratching my head here :wondering:wondering
