Another question. Ive rebuilt one set of forks using the stock springs etc. The second set of forks will be rebuilt with the heavier springs I took out of the track/race bike. since there are more coils in the track/race springs and the spring is longer, I assume I need less fork oil. The Factory Shop Manual calls for 430/450 CC of oil in the forks (Right/left), there is also supposed to be 180mm of air space with the spring OUT (not installed). So how do I decide what the correct amount of fork oil is with the longer heavier springs ? id rather not have to install a stock spring and take a measurement with the spring "In" and then drain the fork again and get the same measurement with the heavier spring, but I cant think of any other way.
