Here's another one of those probably anoying questions. I did a search and couldnt really find anything?
I run a otherwis stock 09 M8 153." the dealer set it up with 68 gram weights in the primary with the stock spring. I ride from 10'000-12'500ish.
Is there anything to be gained from changing out just the primary spring? My understanding is that a heavier spring, helps keep the RPM at altitude ?
If so what spring ?
Thanks
