Glad the wonder is still there and you are still learning/enjoying the experience.I'm equally sure that mastering those improvements will be well worth it as the smiles per mile are way in excess of anything-else I've built (so far). Anyone with ideas in their head should get them out of there and into steel.
I'm of a similar mind. For me , a big part is in the "fun of tilting". I bought my first motorcycle in 1961 (a used 250cc BSA) and I have always loved the feeling of tilting in corners at higher speeds.Depends how you measure it. In distance, probably small. In enjoyment, it's probably most of it.
