I know there's not much Kasama'ing going on anymore but Kasama is alive in the UK still with many parts even kits still available.

I have just tried the optional 13T pinion with the 100T main gear and man it's a hoot! I've only had it upto 1950 on the head so far and I thought it might struggle with this gear ratio but it pulls through it no problem even with the YS91! I also switched to the metal helical crown gear and pinion which brings the tail ratio down from 4.67 to 4.14 which will help when I up the head speed more!

60% of the time, it works every time!

Main gear: KSM70-TS01
Pinion: KSM20-TS17

If you have the stock tail gear ratio and plan to run higher than 1950 head speed I would recommend using 95mm tail blades.
