Booster Plug For Sale

Selling the booster plug for my Speed Twin. Purchased from booster plug directly, had it installed for a couple weeks, didn’t like it, and has been sitting in the box ever since (probably 6 months). We can discuss shipping costs, but I’m asking $75 usd.

 

Sold!! Not sure how to remove the post, so just ignore it you stumble across this.

 

what was wrong with it? still got low down fuelling/throttle issues?
