I would suspect the aggressive valve timing, and glow plug ign.
Ran the 200Ti with CDI on
METHANOL today. Engine ran pretty hot and throttle response wasn't spectacular. Still tried to drop cylinders intermittently.Very sensitive on the lsn, more so than on glow ignition. The timing is set to 31 with no propensity to detonate, even when overly leaned. Seems to need more timing advance. I saw a solid 200 increase in peak rpm over glow ignition and the fuel economy is not only better but shockingly so.
BTW, Saito did make an odd fire twin with a single carb, the FA80T MKl. The MK2 of that engine had dual carbs.
