August 31, 200520 yr Hi Can anyone advise on the level and grade of the oil for best performance on Betor forks taken from an early Sherpa. As they are in long Triumph bottoms, the quoted volume doesn't help. Should the oil cover the top of the damper rod on full extension? Trouble with this is that oil sprays out of the breather caps during events. The anti-splash pieces on the spring bottoms are in place. On full compression, the oil is about 4 inch from the top of the stanchion. Any ideas? What grade would be best for the UK climate? Cheers
