That is cool Brother
As the Broadmarsh Banks crew were mostly in Nottm Raleigh used to try the odd weird invention out on us.
They toyed with making petrol bolt on engines for BMX's and gave one to Mark-Ice to test.
Think it was 45cc with a brake lever (tech 3) for the accelerator.
We fixed it on an old Haro gen1 (with coaster tuffs) and it fckn flew.
Mark-Ice might still have it in his shed somewhere.
Bolt on the faith. L
