Thanks Chuck,
Yep the Sonic springs are a straight rate spring, if memory serves me they are the 1.2 not 1.5 I'll have to check my files. 15 weight for oil is correct. You will need to get more pvc pipe for spacers because Sonic does not send enough, I used thick wall water well pvc pipe. My fork tubes are slid up in the tree 3/4".
When I rebuilt mine I replaced all the fork bushings and seals, may as well do it all with the amount of work it takes I didn't want to do it twice.
The ride is a little firmer but not harsh by any means. It makes the handling much more precise, no more fading to the outside in long sweeping turns, also turns in better in tight twisties.
I am running a 130 tire up front and a dark side BF Goodrich TA Radial rear. 0 PSI in the forks, 20 PSI in the rear unless towing then I max out the rear air.
I'll post a few pics when I get to my pc.
