So glad health issues aren’t progressing and to be happy in a job...icing on the cake! We’re climbing out of our winter so may do away with the heated gear for a bit. I had some custom heating elements installed into a pair of my winter gloves and combined with my jacket liner and socks I was toasty warm even running at 0F temps. Something I’ve never experienced before.
Cyber hugs sent for you and the pups!!!
Thanks Paul. And it puts a huge smile on my face to know you are still riding regardless of the weather. Sorry to hear your body wants to slow down, I'm sure you'll find ways to keep on chewing through those miles with the wind in your face

I'm quite sure you'd love her! I would be surprised if a couple of hours were enough for you... I suspect you'd actually ride off into the sunset, never to be heard from again

Yes, first build I learned the hard way that HD factory spec tight on the pinion nut is NOT tight enough for this power and scuffed the cylinders. So a 0.10 overbore and the lighter XR crank later I have this incredibly enjoyable ride. I also just run with the 560 cams which has the power right where I want it for a spirited street ride.

when young I rode a carbed 88'' cubic inches 98 Sporty... I remember her had a velocity stack who was sucking butterflies inside itself when idling...

100 hp totally different from a 100 hp produced by a jap 4 cylinders dohc of that time

i'am very curious to feel 120 hp on a fuel injected 2007 Sporty... ponies right where they should be... it's worth... for such a similar bike... being equipped with top notch sport rims and sport tires...
