Ignition Advancer?!?

[HoDiggity71]

I recently changed my CBRF4 front sprocket set up from 16t stock to 14t. I also ran 51t in the rear (up from the stock 48t) for a while. I loved the increased power but hated to hear the bike working so hard. A co-worker mentioned that I dropped my "low end" and should add a 4+ Ignition Advancer. I have tried to some research but have not found what this will do for the bike. Can any one shed some light on what the Ignition Advancer is going to do in this situation?
THANKS!

you didn't lose any low-end from swapping sprockets. if anything, the change effectively increased your low-end power. Engine-wise, nothing was altered, just the lower effective gearing makes your acceleration quicker.

An ignition advancer does just what the names implies. It sends spark to the cylinder 4 degrees of crank rotation sooner than when compared to stock. Its kinda like turning the cap on a car distributor to put in some more timing. The only difference I've ever noticed with one on my old bike was a slight increase in throttle response. It prolly added like .5hp but that really wasn't what I was after. The added timing helps to burn the juice better, but on bikes the effect really is pretty small if hp gains is what you're looking for.

Thanks for the info....
