April 9, 200917 yr The 30year old manual suggests using 10/30 fork oil and 126cc in each leg. Does anybody use 5wt oil or any other weight ? Only asking as I use 5wt in my Beta and it would save me a lot of money if I use the same in both. Does anybody use the 120mm air gap principal (spring out) rather than measuring 126cc of oil. Regards Gareth
April 9, 200917 yr Yes I use the 125mm oil height method 5WT for oil is too light for those forks (they are not cartridge forks) 15WT or 20WT is more likely to be what you want
April 10, 200917 yr Yes 5wt is too light, my bike just kept topping out all the time over rough ground, very annoying, as the front end gets skitterish. I prefer the 10wt to slow the damping rate up now.
April 10, 200917 yr Author Thanks guys. Just bought some 10/30 oil. Feels pretty good but the forks arent on he bike yet. I am doing a full restoration of the bike from the front end bacwards and the forks were first. Gareth
April 10, 200917 yr hi, the book says sae30. (not multi grade). I got a ltr of sae 30 from a lawn mower shop and it works very well.
April 11, 200917 yr Author Sorry, meant SAE 10w/30. Works fab. Can't wait to get the rest of the bike rebuilt now.
