i've thought about putting synthetic in my 70 bsa 650 lightning. i run 20/50 dino or 40 wt dino?
i also thought about putting synthetic gear oil in my tranny. any suggestions?
the bike has high miles for an old bsa: 40,000 or so. it does tend to run a bit hot on any weight dino oil, so that's my reason for switching to synthetic.
there is a sludge trap on the crank and I've heard this sludge will break down and get into the oil pump if i used snthetic.
ever heard of this?
