Bajaj Auto — Pulsar 150 BS6 Throttle Body Issue TN10BL0073

I purchased a bike Pulsar 150 BS6 from Popular Bajaj automotors it's been 2 years and my bike has already started to show some issues in Pick up. I asked for repair at 3 rd service in Popular bajaj in porur chennai, they just told solved the issues but after 1 month it again started showing same issues again and again for past 1 year they don't tell what is the problem in engine. Now i recently service in my bike at Sussee Bajaj service in Kancheepuram now they said the problem is throttle body should change i ask for claim in warranty but they not consider to claim warranty so kindly help with the issues for change my bike throttle body.
Please consider seeing to this...
