i have a question about which springs are the hardest of malossi
http://www.malossi.com/Archivio_Files/MONTAGGIO/7311234.pdf
according to this table the black ones are the hardest ??
and if i have low rpm at the start and a little bit later it goes on very high rpm, so i should get black ones (hardest)
i got yellow spring right now, red big spring and 5g rollers
