Just recieved new springs from Freddette Racing and am getting ready to do the installation shortly. What is the proper weight oil to use (just purchased BelRay 15w from dealer)- noticed on sheet from Freddette Racing about this and it recommended Spectro 125/150-whats this all about??? Also anyone know the oil level and how should I go about this (oil level gauge-no one carries them), checked owners manual and it recommends filling level by measuring in a measuring cup. Also no drain screw on bottom of fork legs- do I have to take off forks and turn upside down to drain? What about spacers(PVC was included with springs) how big and where do they go. Any special tools needed for the removal. I know these are alot of questions but I have never done this before and I just want it done correctly with no unpleasant surprises.
