Told PCV Not Recommended.....By Dealer

IF you remove the secondaries there is evidence to support removing the cross shaft as well. OR simply have the secondaries open.
I fly in the face of conventional wisdom and DO close the secondaries a bit at lower rpms - though NOT the Triumph numbers.

Well I spoke with my HD guy, not a dealer tech, and I totally trust him when it comes to my Harley. He does build hyabusa engines but sends them out for tuning. So he doesn't work on Triumphs but started talking more technical stuff about tuning etc. One thing that came up was removing the secondaries and he got into something that I've seen other say. That everyone want to totally eliminate them, not referencing specifically rockets but in general, and that's not always the best thing. So with out making this post more of a novel... I'm just thoroughly confused and frustrated and apparently will just keep the thing stock with the exception of the slip on exhaust that I bought. Although I've even had second thoughts about that now wondering if just a 12 tune will be enough. WTF!!??

some will argue that you should leave them partially working to smooth the bottom end but the tweaks I have put in to the tunes seems to have the same effect, at the end of he day the choice is yours, contact me when/if you decide what you actually want
