My GRiSO 8vSE rides roughly, especially the forks. I've set compression and rebound damping as low as possible, but no joy.
Here's the question. If I were to pull the forks and take them to a quality suspension shop, can they remove the springs, compress the fork legs, and measure the factory installed fork oil level? The quality of my Triumph T100 ride was dramatically affected by fork oil level. I would measure the level using (of all things) a turkey baster that I'd marked with hash marks every 10mm to accurately remove fork oil. I'd start at stock level, remove 10mm, reinstall forks, ride, and repeat if necessary. Of course, those were cheap damper rod forks, easy to remove the innards. I think I'd need special tools to work on the Showa forks on the GRiSO, and would have to use a shop to disassemble and reassemble.
Anyway, I'd like to try adjusting Guzzi fork oil level to see if I could arrive at a level that would result in a more controlled and compliant ride. I'm not into throwing $1200-1500 into the front end of this bike.
