"is there any reason that you can think of why we shouldn't run it like that?"
Cos the neighbours might come round & clout you with a lump of 2 by 4 for waking 'em up every morning with yer unsilenced bike? Mind you, looking at the size of the back garden you've photographed it in, maybe they won't hear it.
I used to run tapered "Shotgun" silencers, (cheap Harley Sportster copies), on my XS650 chop & it was still bloomin' loud.
Looks fabulous mate. I'm so glad the billet barge look seems to be giving way to back-to-basics, hotrod/bobber/flat tracker/board racer styled bikes. Probably cos no-one can afford the billet anymore.
Something very British looking about that, even with the motor from the Land of the rising mushroom cloud.
Purely personally, if it were mine, the only changes I'd make would be a set of similar Shotgun pipes, which would finish somewhere near the end of the little black teardrop toolbox, if only to keep the local boys in blue & the MOT man a litle happier & to keep the paintwork that lovely baby blue rather than sooty black. I'd also have fitted a Sportster tank, but that's just me -sorry, I just like 'em, (yes, my new trike
has got one), & a slightly curvier Paughco style solo saddle, (yes, my trike's got one of those too).
Tis a lovely lookin' little machine though Pie. I hope you'll grace our Motors section with a write-up before PantherShaun poaches you for Brit Chopper?!
