Hi Aaron. Your gess about the weather is right. And when I start riding again I like to have some numbers on the performance with the large carburettor.
The weight for the balancing is added and I noticed no different vibrations. I leave it like this. Reducing the weight brings no big advantage at low revs.
I used the time in this winter to make drawings for an upcoming change. Adjustable inlet valve timing. Adjustable during riding. Like Toyota Prius. Early inlet valve opening and closing for low rev torque. Late closing to get carburettor backflow and have a better ratio of compression stroke vs power stroke. Like the Atkinson approah. More info will follow in due time.
On the CVT. I enjoy the characteristique during acceleration. Even with a high gear (starting in second in my case) acceleration is very well.
If you look at the efficiency of the CVT that is lower than manual transmission.
Info from various sources give efficiency of around 85 percent. Where manual transmission is between 95 and 98 percent. So probably a difference of 10 % in FE can be expected.
Somewhere in the future I will test that.
regards
Jan
