The pursuit for a brown sparkplug

@2stroketerry said in [The pursuit for a brown sparkplug The Aprilia RS 125 SP, or Aprilia AF1 125 Sport Pro run a Dellorto PHBH28 RD 28mm carb. This carb together with a Gianelli exhaust, gives more than 2HP extra power over the 34mm carb version! More than 35hp at rear wheel...
The DT 200R makes 33 bhp and uses a Mikuni TM28SS carb so do not always need a bigger carb for more power, but a well set up carb with jetting spot on 100%.
33 at the crank maybe no way at the rear wheel lol, a crm125 makes 29 but even after a dynojet session the best ive seen is 21.4 at the wheel on the dyno. 21.4 is about what an old 89 DTR makes at the crank lol. A well setup carb is good
