FAQ Section:

1. Which models does this spring fit?
Only Royal Enfield motorcycles with the UCE engine platform like Classic 350/500, Bullet, Thunderbird, and Electra (pre-J series).

2. Will it fit Meteor or Hunter 350?
No. These models use the newer J-series engine and have no kick starter, so this spring is not applicable.

3. What does this spring do?
It ensures the kick starter lever returns to its original position after kicking. Without it, the lever may stay down or feel loose.

4. Is it a genuine part?
Yes, this is an OEM Royal Enfield part with part number 146450/C, verified via trusted dealer catalogs.

5. Can I install it myself?
Yes, but it requires opening the right-side engine cover. Recommended for experienced mechanics or during clutch/kicker service.
