Way beyond stock now... 8 Pedal V Force reeds HPI Mini @ 3mm No starter clutch Pull start Big Muff 14x30 the strongest highest stall springs I can find at the time... I break springs and clutch arms monthly. Red Contra TJT with like 10.5g Some light porting and some skirt and piston chopping. Puch Gila head for that sweet sweet squish and no decomp. Was clocked at ~67mph with 17x30 gearing.

@evan folwarski This bike hasn't been stock in a while... Garage won't late me change the name. I think I'm getting a good 55 out of this with crazy acceleration. Great sprinter for NYC. Still have some porting to do before it's finished.

I've heard that derbis that are "mostly stock" can push some pretty impressive top speeds? what you put out with this settup?

Silver variants are the best.
