All tests were done on my Pinto using a non-ported, case-matched Gila and head, stock reeds, 24mm Mikuni flat slide, HPI ignition, 24mm intake, pump fuel, and 16x36 gearing. I did two pulls per pipe and kept the best results.
First, the BK100: 11.2HP, 12,900RPMs, 7.7 ft-lbs of torque, and 68.1MPH
Second, the Putt-Putt: 11.7HP,13,300RPMs, 6.3 ft-lbs of torque, and 69.9MPH
Third, St-Ripper: 12.9HP, 14,500RPMs, 6.3 ft-lbs of torque, and 76.2 MPH!!!!!!!!!!
I had a few minutes left on the Dyno, so I threw the Motion Bee Lectron carb on and gave it try. The results are good, but not great due to the lack of time I had to tune this beautiful carb.
Last pull of the day, using Motion Bee carb and the St-Ripper,
12HP, 14,500RPMs, max torque of 5.9, and 77.2MPH!!!!!!!!!!!!!!
The carb was extremely rich across the board, so we are getting new metering rods made for us. This carb has tons of potential, i just didn't have the time or tools to unlock it. We're focusing a lot of energy into getting these carbs dialed in, and will be heading back to the dyno with them after a little more testing.
Thank you to Stock Pro Performance for the Dyno time, to Emmanuel, Eric VanDippinDots, and all the moped community.
I am very pleased with the performance of the BK100 and the St-Ripper, both on the Dyno and the street, so I am happy to announce that these pipes are now production-ready and we are accepting orders for these pipes. They are available for all makes and models of peds.
Keep your eyes open for our new website, mlmopeds.com, it'll be ready soon. Until then, orders can be placed at:
