Project Nuts & Bolts is an institution of Australian custom bike building. A slip-on reverse-cone muffler was knocked up and bolted on. Sounds easy, eh? It took a bit more work than that but the end result is a true bolt-on, fully stainless-steel muffler with black coating and a polished end-cone. Dyno numbers are part of the final equation but the sound has to be right. Indeed, Sandy and Adam got both the sound and performance right. With deeper breathing possible through the DNA air filter in the lightly modified airbox, the fuel supply needed help. We started with an EJK (Electronic Jet Kit) 3.0 that allowed us to add fuel anywhere between idle and redline. Thankfully, Dave Holdforth from Sydney Dyno provided his expertise and experience along with his
Dynojet 250i. The improvement from the new Staintune muffler was obvious but the air-fuel ratio was all wrong. We needed to remove fuel and make the fuel curve leaner, something that isn’t possible with the EJK 3.0. Pete Lucas from Kenma contacted EJK who quickly sent out a prototype EJK 3.5 that allows addition or subtraction of fuel. Back on the dyno, Dave was able to dial the fuel curve in very nicely. Project Nuts & Bolts was now making 55hp and enough torque to carry a fat editor up any hill in top gear. The lucky winner of Project Nuts & Bolts will be sitting on a DayTripper seat, the very first custom seat Mustang Seats has made for a Bolt. Not only does it look just right, it is also extremely comfortable. The

winner’s feet will rest upon a set of genuine Yamaha semi-forward controls. Might not sound like much, but the four inches make a big difference to the rider’s comfort. Lifting your hands up to the handgrips atop the Ventura 10-inch apehangers places them at a very comfortable level below shoulder height for most riders. Venhill braided brake lines provide the feel and fluid retention that brakes need to work properly. Clutch and throttle cables were too short so Justin from Trooper Lu’s Garage organised a new set of clutch and throttle cables from General Auto Cables to match the increased height of the Ventura handlebars. We also got to see Mick get his hands dirty alongside James from Trooper Lu’s Garage. While James was fitting stuff
