First of all congratulations on the new bike.
Now coming to the problem, explain what do you mean it doesn't move freely ? Does it touches the ground or is it hard ?
If it is touching the ground than you need to change the spring of the main double stand, if it's hard than probably chain is a bit too tight get it loosened a little bit from some good mechanic.
As far as running period is concerned here are a few points
- Change oil at 300kms.
- Ride b/w 40-50 uptill 700kms and than rev it hard from 700-1000km to open the bike properly
- Get its tuning and oil change done at 1k kms
- Never let anyone touch it's carburetor during or after the running period ( factory settings are not to be disturbed)
- Get it cleaned :S
Hope this answer your queries.
By the way what is written on cylinder is it 78cm3 or 86cm3 ? And you said it's better than other chondas, have you ridden other chonda's is it's performance a lot better ?
