Summer is here and with it, the peak season for riding here in Northern California. We have been hard at work tuning a variety of motorcycles - Harleys, Buells, and several different varieties of metric sportbikes, as well as some assorted other tuning projects, which have kept things exciting around the Dyno room!
We have had the opportunity to do some very successful Formula Ford tuning in partnership with Ron Chisholm of Cypress Lane Racing.
We are also very excited to be tuning a Bonneville streamliner for Brandt Racing in Woodland California. We wish them the best of luck at Bonneville Speed Week this year!
Our own Bonneville Race preparations are underway and we are looking forward to the salt this year! We will be running at Speed Week and BUB's World of Speed.
AFM Road racing season is well underway and we are pleased to be sponsoring three riders! Roi Holster, Tom Short and Garrett Kunkel. Check out their rider profiles on the JT&S Blog!
