I swapped the Honda NX4 RS125 tailpiece from my 4 stroke onto its rightful home on the RS125 chassis.

A few NX4 RS125 expansion chambers also turned up on my door this morning, thanks Jesse! I know they’re not matched perfectly to what I will be doing to the GP engine but Rob has shown that they work well enough to get some great power figures from them. It’s also easier to use an RS one to get it going and rideable instead of stuffing around building one that is likely to be crap. I do plan to build a few in the future though…
