jaylael Posted January 10, 2007 Report Share Posted January 10, 2007 It's on the side of a baby bottle. Since I don't have one handy, I looked it up on internet. 1 us oz. = 29.57 cc so 6 X 29.57 = 177.42 Does that sound right? Maybe just get a baby bottle.

old trials fanatic Posted January 10, 2007 Report Share Posted January 10, 2007 I run 170cc 5W in mine with 45mm preload. Then again i am 1) a fat ******* 2) they are fitted to a B40 which is possibly a bit heavier than an OSSA However http://hem.passagen.se/ossa/ is a site that might be of help? 170cc works in my 199B also and they are Betor forks just the same as the OSSA but whatever.

woody Posted January 10, 2007 Report Share Posted January 10, 2007 The Bulto forks take a bit less oil than the Ossa (maybe due to the shorter legs?) Book recommends 200cc I think in MK1 or MK2 Ossa forks (as per bike pictured) I use 180cc generally with 10W as this gives a relatively soft action but as with most things it is all down to personal preference so you could use that as a starting point. The MK3 and onwards had longer forks so usually 200cc as a starting point for them. Quote Link to comment Share on other sites More sharing options...
