"Horses for courses" they say. That's what seems to be at play here. I gather most folks who'd choose to get one of those nice new 650 twins would do so for more or less the same reason I'm perfectly content to nurse along an old Iron Barrel Bullet: they just want to have a pleasant ride on something balanced and lovely that looks like a motorcycle ought, albeit with perhaps fewer concessions to modernity than I face. Sure, a few sensible mods to clear out a correctable inefficiency here or loosen some mandated emissions chokehold there are par for the course for most owners. But if they'd prioritized the kind of torque and power that caused one's testicles to retract they would have (should have) got a Hayabusa or something. So asking this crowd to wind out and very possibly damage their engines, no matter what anyone claims, will likely elicit only either disinterest, like trying to sell an iPod at an antique radio collectors convention, or even a sense of disgust or mild horror, like someone peddling fur pelts at a PETA conference.
Raw performance is not really what these bikes are about for
most owners, certainly those on this Forum, but that's not to say that everyone necessarily feels that way, nor, for that matter,
should everyone. Yet such a cavalier attitude to longterm engine health takes deeper pockets and other goals than most owners here may have. Another Forum member has already made the very sensible suggestion of contacting the good folks at Harris Performance, who designed these 650s in the first place. Many will recall their
record-breaking runs in the 750 category at the Bonneville Speed Week in 2018. According to other reports they blew out several engines in the course of gaining that new Land Speed Record for the class, so clearly their concern was not with pampering their mills so that they'll carry on through the Malia Obama Administration or whenever. Running nitrous oxide they were interested only in squeezing every last droplet of "Oomph!" from those motors and consequences to them be damned. It sounds to me like our man, "dcolak" might do well to at least reach out to Harris for answers to his questions. The folks who did the Bonneville runs were their Special Projects Team at the Bruntingthorpe, Royal Enfield Technical Centre, but general enquiries to Harris Peformance can be made at
https://www.harris-performance.com/contact-us/ . My guess is they'll have answers to all his questions
In the meantime, I'm hoping our original poster might take a moment to either confirm or deny my earlier linguistic hunch that he is a Croatian-Chilean. Why not satisfy
my curiosity?...
