Don't we all! Not much progress made unfortunately as work mostly keeps me in Bristol while the bike as in High Wycombe, plus I've recently ruptured my ACL and am laid up while that heals after surgery!

Aching to get back to working on (and who knows, perhaps even riding...) the bike though :D

Happy to report that fitting a new concentric has fixed the lean-to-the-side-and-the-idle-changes issue I was having with the monobloc!

Currently using a 170 main jet. Recommendations for going from the 200 in the monobloc into a concentric seem to change from 10-20% reduction in main jet size so I've gone for 15% as a starting point...

Idles almost perfectly now. Slight hanging idle after revving which could be down to either an air leak or my setting the pilot air screw too lean, I believe?

Knee is not yet quite fixed enough to ride down to the MOT station but surgeon cleared me to drive a car without my brace today. Motorcycling soon!
