Comments: After many tests it seems the best. I changed the pinion with a 19. The carburetion in fourth gear at maximum speed is perhaps lean because a lot of air coming from the air intake under the seat. main 125 I beleave I think it is fat in the second and third gear.

Comments: This carb is a bit small for the ported 210 with Mazz Cut Crank and Malossi Reed Valve setup so the settings are a bit tricky. Would work better with a oval slide 30mm carb and best with a 34 - 35mm flat slide carb. The difference is peak hp vs. gas mileage. The 28mm nets somewhere between 30 - 50 miles per gallon depending on how hard it is being ridden. Doesn't get much better than that.

Comments: Pinasco + 60mm Mazz cut crank, timing @20 BTDC, NGK B9ES, milled Pinasco head w/ no packing plate, stock P200 gearing with 23/ 64 Malossi upgear, 10" VS1 star rims. Easy touring at 65mph with 1/2 throttle left, tons of torque pulling in 4th gear from 30mph up to 75mph top. 120/ 50 idle jet and the silde mod essentially eliminated the pinging with the throttle rolled off. BE4 was too rich, causing bogging/ rough transition around 1/2 throttle, and BE3 cleaned it right up. About 55MPG for spirited but not too crazy touring, maybe more for gentle ride.

Comments: Correcting previous jetting note 2 spaces down from this. Did the choke test at full throtle and discovered 110 too big, rpms dropped, switched it down to 107, redid the choke test no change in rpms, much better. Gears seem to have more length and scooters a bit more zip, quickness. Sticking with 107.
