hi there ,am facing a bit issue ,else me but some of my friends too , ybr 125 engine had acceleration missing issue especially after 8000rpm to 10000rpm and just for experimental work we remove egr valve of one bike ,as that was bit risky and tough but succeeded , resulted that hits 125km/hr more the speed , and more average even that was unbelievable thing drive upto 70km/hr and we r having 55-60 km/ltr , bad effect is now engine oil has to be change earlier than before,,,,,,,,,,,,, now my question is is thier be any other substitute  regarding this 

 

The egr valve returns exhaust gas to the engine, your performance is coming from not having the exhaust gas in the charge. This means your engine is running dangerously close to melting the piston.
