1934 Blue Star inlet valve guide lubrication hole

[David Samways]

Just pulling apart the engine on my '34 Blue Star and I find that the inlet guide has no hole for lubrication. It's an easy enough thing to drill a hole in it while it's in situ, but I don't want to go too big or small. Does anyone know what size the hole should be?

Many thanks

Just checked my 1934 350cc spare head hole is 5/32".

Thanks Mike. Is that the hole into the guide itself or the oilway in the head? My head oilway is 5/32"

Oilway in head David not valve guide hole but have just found the old inlet guide that come out of the head and the hole size is 1/8".
