Hi Karl

I would leave alone as the work involved would require a lot of skill to get it right. The extra length in the wheelbase does make them less twitchy than the real ones.

Is that Gary's last chassis, it looks very familiar?

Which Quaife box have you fitted? I gave up on my 25G, as it kept breaking

I see you've copied my 200 plenum to YB inlet, I've also given up on that inlet at the moment as I've blown two of them to bits due to backfires, possibly caused by my wasted spark ignition, although I do have another 200 plenum & inlet to make another.
