i just got my yamaha ybr g in past i used classic CG and Dream there is nothing to worry bro since you passed your bike's break-in and did service than you are good to go just change oil on time this is one of the most important thing and PLEASE! dont take it to hathora mechanics they will destory your machine. this bike well built you dont have to worry about performance degrading over time if you change air filter/engine oil on time then you wont face any issues.
PS: dont over tight tappets if you are riding lot specially in this summer weather. leave it a lil bit loose it will make some noise but its better than having engine problem later on
Cheers
