Been here a day or 2 and from what I can tell-some swear by em and some swear at em and some are happy as piglets in new kaka.

Research here on the tech board. Some have stated that after a trigger wheel install higher octane gasoline was needed. My I/S runs fine the way it is I M H O.

NO-I have not installed an other than stock trigger wheel. Hope I've been some help for ya!!

RIDE SAFE.
