I purchased a Jawa 350 classic on 1st February 2024. From the second day, it starts missing and taking a long self when I start the bike usually when I stop the bike mid-way of my ride and I start the bike to continue the ride it never starts in single self. One major thing that happened to me was my bike broke down one day in the evening when I came out from my office as per my daily routine. I have tried many times but the bike never started. I called the service center and they instructed me to do some stuff but it never worked. The next day they took the bike and kept it for 5 days to check the mistake in the bike but they didn't find anything. They called me to take the bike and said there was no problem and suggested they use it for 4-5 days and if the mistake occurs again they will arrange a solution for this. Now the missing in the bike is still the same and the engine makes an annoyed noise. I am totally disappointed and unsatisfied. Jawa failed again.
