That's good to hear!
I wonder though if you enjoy the journey of making this bike special, as much as you do riding it? For some folks that journey is part of the enjoyment.
That's a good question. I definitely enjoy "farkling" my bike. I've always tended to view stock bikes as a blank canvas begging to be customized to suit my tastes. That in mind, I do what I like, but I'd also like to think I do things tastefully and go for a clean look and good purpose. I love riding as much, I ride instead of drive whenever possible. Driving a car is pretty much torture for me.
Since you're one of those people who made the N1k more sporty, did you consider taking, say a literbike Super Sport and just made it more comfortable? I do believe there is a huge return with very little $$ spent in simply fitting a liter SS with higher clip-on's and adjustable footpegs, bigger windscreen, heated connections, throttle lock, etc., because the performance gain is tremendous from an N1k platform to say a ZX10R platform. 30 more rwhp at least, 70 lbs. weight reduction, way better suspension and braking. That's a huge gain before any engine mods are even considered.
I think the closest I got to that was an '05 R1 with heli-bars. When I had my '15 R1, heli-bars didn't release their bars for that bike yet. Such a bike would be fine for most of the riding I do, but I don't think It would be as nice as the N1K for the few times a year I take a longer trip. Like when I rode up to Laguna Seca this Summer.
The Yamaha MT-10 is about 90% or so of the the current R1 is. Basically same chassis and engine. The only issue is that it's naked. If it had at least half fairing like my old '09 FZ1 had, I'd pull the trigger. I have seen some giant touring like fly screens available for that bike, but I just can't live with way that looks. Aesthetics still matter to me.
At this point, the only bike I'd replace my N1K with is the H2-SX. I normally keep my bikes at least 4-5 years if I don't total them like the last bike, and I usually wait until my wife has leased a new car so she can't say anything when I tell her I'm buying a new bike. Haha.
