Hi Trevor, best to make up your own mind and be happy with your decision. My 1926 Scott, which I have been riding now for 13 years, has a pilgrim pump converted to drippers. I run Valvoline 2 stroke oil. I have set each one to 8 – 9 drops per minute and have had no trouble. I noticed on a hot day – here in Australia – the drip rate does increase. But it is never a problem, doesn’t oil plugs and the electric start we fitted 4 years ago still works well. I have just enjoyed a 3 day weekend riding my Scott around the Western District of Victoria in glorious spring weather.
I have had this problem in the past with my 2 speed, and it is easily fixed. Disconnect your oil feed, and was out with degreaser. We have found those pressure pack cans of degreaser work a treat. If you use a synthetic oil – it is too good, and will cause the clutch to slip. The only other thing, make sure you haven’t got the push pull rod too far out of adjustment. (Thats the rod that runs through the centre, the little washers inside control how far it travels, all this is written up else where by more technical people than me!) Hope this is of some help. Cheers for now. Catrina Sargent. (Australia)
