NIKAVI SP02 Conventional Spark Plug Compatible for Hero Xtreme/Sport

Please don't buy this spark plug 🙏 it's my humble request, the quality of the plug is soo poor, instantly after installing it I noticed that it was creating a higher number of vibrations compared to the old one and it's the 3rd week going almost and this week my bike started boggling during acceleration, I thought the fuel was a culprit as for the first time I filed my bike with e20 fuel but it was all ok, secondly I thought some water might have entered the tank as it's monsoon going on,but it was okay too, then my mechanic told me the spark system could be the issue, he first removed the spark cap and checked the raw spark, and told me to give him the old sparkplug, upon inspection we got to know that the sparkplug is creating an issue of actually 2 issues, firstly vibrations with is kinda bearable and second was that it doesn't provide enough current for startup, if you have read till here, please consider buying such auto item via offline shop only.
