    yes you can lap them in but they should really be cut in. IMO if you're running stock springs aftermarket valves are useless. Stock valves are perfectly fine in any stock spring scenario

    I'm thinking he is just worried about having the faulty valves like the 04-05 rxp valves. Of course you can run stock springs but those valves can handle much better springs and retainers which is totally worth to spin the motor up higher.

    [QUOTE = toxicgun; 2512512] [QUOTE = imp0ster; 2.512.508] Sì, è possibile li lap in ma in realtà dovrebbe essere tagliato in IMO, se si sta eseguendo magazzino Ammortizzatori valvole aftermarket sono inutili.. Le valvole di archivio sono perfettamente bene in qualsiasi scenario magazzino primavera [/ QUOTE]
    Sto pensando che è solo preoccupato di avere le valvole difettose come i 04-05 valvole RXP. Naturalmente è possibile eseguire le molle azionari ma queste valvole in grado di gestire le molle molto meglio e fermi che è totalmente la pena di girare il motore più in alto.
