My 1991 KDX 250 front light is dim

I belive it soposed to be kinda dim until u rev it up alittle. atleast mine is dim till it revs.:think

Mine is dim until it's revved up as well. It's supposed to be that way I'm sure. Kawasaki's version of a Hi-Lo beam.:D

I ride mine at night all the time with no problems.

Silly question time.

Have you checked the bulb is std issue? Many people put in a car bulb & the puny alternator cannot run it. The alternator will put out very little power at idle, Without a battery the bulb will go dim.

Yam Blasters & other such horrible 4 wheelers, run Halogen 12V bulbs of about 35W from memory, or was it 25W?

You can get specialist firms to rewind alternators for more output.
