shercosteve Posted October 27, 2016 Report Share Posted October 27, 2016 Hello, I am looking to service my forks on my 1986 RTL 250. Any suggestions on oil capacity and what weight should be used? The front end seems very soft even with 10mm longer preload spacers, is there any aftermarket springs available? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
barfy Posted November 1, 2016 Report Share Posted November 1, 2016 Hello, I don't know about the aftermarket springs, but with regard to fork oil the manual says: Quantity: 258 +/- 2.5cc Level: 160mm from the top of pipe From experience it's better to use the measurement from the top of the pipe because it provides better results. You should move the fork up and down several times before measuring to remove any trapped air. I'm sure that I used 10 weight oil. The manual says to add extra air to the forks to adjust for the weight of the rider to a maximum of 1.5 kg/cm. Hope this give you a starting point to then make some finer adjustments. 1 Quote Link to comment Share on other sites More sharing options...
