Thanks for the kind words! Send me an email to alain@motomotto.ch (if you have with some images of the carb) and I'll mark on it what I know. A bit hard to explain using text 🤣 but drain is at the lowest part of the carb (little nipple facing straight down on main carb. The drain screw is horizontally mounted (accessible from left side of engine when loosening the oil cooler)

Salut, Just a question about how to do the synchro of the primary and secondary carb? I mean the second one open the valve at a certain point depending the opening percentage of the primary carb's valve, that synchro can be adjusted by a screw that adjusts the opening of the two boxes. Do you have guidance to achieve this process? Merci beaucoup et bravo

@@r_m_masson the manual (at least for the newer carbs) recommends to set the throttle valve 7mm open on idle. However I always crank the throttle shaft fully upen and make sure the throttle valve on the secondary carb is horizontal. That always worked out for me
