Yezdi Scrambler Automatic User Reviews

I own yezdi scrambler it's been 1 n half year and the timing chain broke for 2 times even though i don't rev that much on low gear n i do top speed some i drive normally around 60 to 70 on a daily basis n the mechanic say that i might rev too much or i drive rash driving but i don't n when i doo cold start n try to ride it and change the gear it automatically revs too much i complain about this to the mechanics about this problem but they said it's natural.If it's natural then why i have to deal with this timing chain problem and the mechanic of jawa yezdi nlg takes too much time to repair it and the making charges are too much high and they don't even keep the parts available sometimes.
