i have seen these on ebay alot of times. wondering what you guys think about it. will it really give me more hp? will it just toast my electrical system? i guess im asking if it is a safe hp gain and if its worth the 89$. anyone have one of these on their bike? thanks in advance. heres the link I-Kat Cat Ikat Booster Spark Amplifier DS650 DS 650: eBay Motors (item 370418430294 end time Sep-08-10 14:33:52 PDT)

 

its a gimick..... dont fall for it, if it worked you would have heard more about it by now trust me

 

if anything buy the high performance coils. but since the ds aready uses a dual plug, dual coil setup . i doubt you will see any improvment in power. unless you have a turbo, very high comp. ect .the best mod's are a cdi and the best plugs you can get,

 

i do have a cdi already and as far as plugs what would you say are the best?
