Hi fella, I picked up a really handy tip off the forum when replacing the grease (muskrats or bsa bills idea I think ?) put the new grease in a Jiffy bag, put it in the freezer overnight and before your about to put the timing cover back on get the grease out of the freezer, snip the corner of the bag and pipe the grease in, that way the grease doesn't just run straight onto the floor and on your new gasket. I made up my own grease (slightly runny) by mixing straight 40 oil and grease. I think if you use standard grease (ie thick) the dynamo chain cuts a track thru it and doesn't lubricate the chain. All the best, Chicago.
