Congrats on diving in, Frederick.

Hope you don't mind me splitting this off from the other thread: Blackfly XFi? Cam swap! Update: swap completed

Your transmission/camshaft project is threadworthy on its own.

I'm surprised you didn't notice a difference in 1st gear. The F.D. in the Flea is high enough now that it takes noticeably more clutch slip to get going smoothly from a stop. It's not a big deal on the flat, but it's particularly evident on hills.

Here's a question: is there any size difference between the wheels/tires that the final drive came from vs. the wheels/tires on your car? My speed/odometer is off now because the 4-cyl transmission was calibrated differently due to different tire sizes. It's off by almost 6% - in the direction that further lowers the effective final gearing, numerically.

Looking forward to your next update!
