My colleague has an XJ900. It started loosing power and running rough. The fault was down to air leaks in the carb inlet rubbers.

Apparently these are of composite construction with the engine block portion being aluminium and the carburettor portion being

rubber. The rubber portion being moulded onto the aluminium portion. Genuine OE part replacement is around £100 ....4 being £400

obviously. Quite a kick. For £23 a set of four rubbers for a Honda CBR600F can do the job. They are 42mm Mikuni side and 40mm the other.

The alloy inlet needs cleaning up to accept the short staight rubbers and eight suitable jubilee clips obtained. I have a good photo of these

but have not been able to work the 'Imgur thingy' and I'm not allowed to paste it here.
