What's the preferred secondary spring in a 600 with say a 46-42full progressive.
Generally have used 140-200, thinking of 140-220. Wondering if it will hurt topend mph.
 
a little!! i gain 8-10 km/h between a 140-220 and now a 140-200 (but lose 100-150 rpm)
 
After the spring swap it only turn 7900-8000rpm , i grind 1 gram off my modded 66’ and gain back my 8100-8200! I’m doin 170km/h gps now on 2-3 inch flufy snow!.
