FMF AOF ignition on RM125

[RM_Dude]

Do these things really improve power or just a gimmick?
I have a 1999 RM125 I'm considering purchasing one for.

Thanks in advance for any info.

For $ 99 you won't get anything better that will give you the gains, and it bolts straight on,,

Stevep, have you tried it on an RM or only Yamaha?
I don't know how much difference it would make between the various manufacturers but just curious.
