Dear Bike Experts

I own a Bajaj Kristal scooter purchased Dec'.07. Ever since facing perennial starting trouble.
I guess the vehicles charging circuit is defective (doesn,t charge even after 2 hrs of daily running ).
The starter, most of the starts, feels like lacking the power to crank the engine.
Repeatedly highlighted this problem to Authorised Dealers like Khivraj Motors - Chennai and
Alegendra / Jaikrishna motors Coimbatore. None has bothered to rectify the Design mistakes
and the company also never bothered to improve.
Strongly feel if the Charger , Battery and Sarter capacities are retrofitted with a better model kits,
it might resolve the issue.

Can you guide which other scooter / bike,s parts can be retrofitted to solve this problem.

Need the answers badly as its become a daily struggle and the scooter has become invalid.
If you dont have the time to bother on a dead model , pl guide to the correct source
who might be of help.

Hoping for a solution from the best bike brains in India.

Warm regards
