Small Engine Fuel Injection Kit for 125cc to 200cc engines costs $500, thats close to FIFTY THOUSAND RUPEES!!!
The kit is for Americans, who use a lot of small single cylinder engines for home built scooters, ATVs and buggies. These engines, usually called GY6 engines, have built in automatic transmission. They like to build their own rides, they can afford to buy and use this kit.
I don't think this kit (costing almost half the price of motorbike) would improve the performance of factory built Pakistani bikes.
