Less acceleration and higher top speed than stock (marginal though)

Standard chain would be fine as you're only 1 tooth smaller than the standard size.

Going by Shazaam!'s calculations I make that a resultant 4mm reduction in ride height that you need to correct for.

Bit of an odd choice in sprocket though, how come you went smaller than stock?

I run 14/39, but still have the longer 96 tooth chain (ride height was re-set).

mr s, i had to go for a smaller sprocket as it was the only stm sprocket i could find in this country

Saw that from your other posting afterwards.

It seems STM are stopping / stepping down manufacturing a lot of their products to focus on slipper clutch production. I had major problems getting hold of vernier pulleys and had to use another source instead.
