Yes, my bike has a manual choke. Now that I have fitted the original exhaust, and I have run it with E5 98 and Liqui Moly Card for a few miles it is behaving much better. It did still cut out on deceleration when getting down to 1st gear once or twice, but it will now idle when hot. I still get bang-and-pop on over-run, but with the new (original) exhaust it doesn’t sound nearly so bad. I did get a new air filter at the start of this year (along with the £600 service!) and comparing the colour of the old and the new it could have been the first new air filter for a very long time. It is now SORN for 6 months so I’ll start it up and idle it every month till Spring and then I’ll be sure to check the timing. I also got a brand new radiator for it from Aliexpress (item-1005005776337812) for £60 (bargain) as the old one had a very slight leak and I asked the servicing garage to add some ‘leak-stop’ (which I now see the manual forbids). So it should be breathing very well and keeping cool.
