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!

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.
