Pleased to report my Sportster has been out and running over the summer, including a lovely run recently through Cheddar Gorge and surrounding area:
Engine running superbly, cooling issues all sorted, brake pedal is sticking a bit (needs a better spring) and odometer not working but overall very pleased.
My other project is coming on nicely, although I have had to slow down recently due to a sciatica flare-up.
Best of luck with your engine swap, let us know how it goes.
Cheers
Tim
