Bhai ji aap ny race race khelni hy ya ride enjoy karni hy? I guess you can fix it by replacing its meter with some good branded one like Suzuki. Ybz ka techie meter ki needle bhi wobble karti hy and it’s a factory default fault in it. Yamaha is getting lot of complaints about its meter and in future they surely will do something to fix it. You better first contact yamaha service centre and get a replacement for free.
Further, I would suggest that forget about speed and always drive carefully. My last accident was on yamaha royal YB 100 in 2005 and still I feel pain in my left arm specially when winter arrives.
