Not having used petrol/oil mixtures since my Bantam days in the early fifties when the mixture used to be 16 to 1 using Castrol XXL, What ratio do people use in their Scotts and what oil do they use? Also, I’ve acquired an engine that has been fitted with grease nipples to lubricate the main bearings instead of oil from the Pilgrim pump. Has anyone had experience of this system? How often would one have to grease the bearings if I retain this system?
Thanks for your replies guys. The engine I have is a very late Shipley engine modified possibly by Ian Pearce. So no speedway engine! The guy I got the engine from, bought it from someone’s estate at auction and couldn’t give me any info. regarding it’s history other that it hadn’t been fitted to a bike or run.
Hi Dave I know that Tony K my nearest SOC member has an engine converted by Ian Pearce, I am sure that he told me he greases his engine every 300 miles maybe if he sees this he can comment, regarding petroil, as you know I run mine on petroil and would never have a Pilgrim pump anywhere near a two stroke engine, I would always use the best synthetic two stroke oil available regardless of cost, after all none of us do that many miles on a Scott to worry about oil costs. I use 25/1 mix because I use mine hard, and a normal Scott big end is not really designed for petroil, it`s not designed for direct oiling either! my big ends are different.Alan Noakes. email@example.com
I run my old nail on 50to 1petroil in the tank and a pair of drippers to the mains I have used this setup since 1972 on varicose Scotts using Saab oil when available and then Stihl oil with 50 monograde for the drippers . This works for me and as has been said PilGRIM not for me.Regards to all. DF.
A chap I helped a few years ago had an engine rebuilt by Ian Pearce and fitted with grease nipples on the main bearings. I have lost contact now but I am sure if you give Ian a call he will advise on how often to grease.
