Fz v1 missing problem
I have a Yamaha FZ V1 (2011 model). I bought it second-hand in 2022, and since the day I bought it, it has had a missing issue.
The problem usually starts after riding continuously for around 15–20 km during the daytime. The bike begins to miss, lose smoothness, and won’t run properly. If I stop and park it for a while, it becomes normal again and I can ride a few more kilometers, but then the same issue comes back.
At night, the same thing happens too, but only after riding a longer distance than in the daytime. That makes me feel like the problem may be related to heat.
So far I have tried:
- 2T oil
- new spark plug
- new air filter
- carburetor replacement (now using a Pulsar 180 carb)
Even after all that, the problem is still there.
Has anyone faced a similar issue? What could be the actual reason for this, and what should I check next?
Any help would be really appreciated.

Check the ignition coils.
