Basic modification

Practical approach($250 cost)

Stratified charge 2stroke engine• Compressor injects fuel mixture near spark plug, no fuel

lost during scavenging = 100% < Fuel Efficiency

Results achievedBefore AfterWeight =120 Kgs Weight = 90 Kgs

Fuel efficiency = 28 Km/L Fuel efficiency = 60 Km/L

Emissions CO = 2.4% Emissions CO = 1%

Repair cost after fall / Minor accident = $ 75

Repair cost after fall / Minor accident = Nil

Back ache after ride duration of 1hr

No Back ache even after 3 hrs continuous riding

Maximum Speed =80 Km/hr

Maximum speed =100 km/hr
