I have already checked the wires to the coils and they look fine, maybe it all else fails when the carbs/jets and reeds have been checked and the power jets have the correct x and y pieces have been sourced, then I will run another wired to the coils..just to be sure. Compression on front cylinder has also been tested and is fine - I cant check the top cylinder as the frame gets in the way of the compression tester .
Does anyone have any spare x and y pieces (if they have fitted HRC kit they must have some just laying around

Alternatively does anyone know if the ones from my MC28 will fit? Maybe I could take them out and try them.
