I got a domed hi comp head tiny fins looks like zippy the pinhead on the hero or airsal.
Its 70cc tho.
Swapped to the kickstart bottom and herokit. Keep in this as back up. Same funky angles on exhaust and intake.
The Colibre is getting the airsal reedkit and pedals. Technogas next pipe. Amal 19 if I can get some jets.
