If you're looking to get the most out of your engine, upgrading your cams is a great way to significantly increase performance without breaking the bank. The British Customs Performance Stage 1 Street Cams Service for Speedmasters and Americas takes your current cams and regrinds them to deliver better low-end and mid-range torque. With this cam upgrade, you gain quicker access to your torque band, and have smoother horsepower delivery throughout the RPMs. But don't let the talk of engine internals scare you away from your pursuit of horsepower. The cam simply drops in, requiring only that you remove the top cover to access the stock cam. The cam is precision ground to keep the bike streetable and reliable. Lobe center values are modified to increase both lift and duration cycles that up the ante, delivering more air and fuel for bigger torque and horsepower. Valve overlap is increased but not enough to adversely affect idling. Get the most out of your engine with the British Customs Performance Stage 1 Street Cams Service.


  • Precision ground for maximum performance
  • Better low-end and mid-range torque and horsepower
  • Will not adversely affect idling
  • Lift and duration increased

Note: British Customs Stage 1 Street Cams Service is a mail-in service. (Core exchange required. Customer must send in his or her cams. After our receipt, cams are returned after up to 2-3 weeks of service if existing core is unavailable for exchange. Customer is responsible for all shipping costs. Call for any inquiries.)

What, if any, intake, exhaust, and fuel programming are required to make this modification work optimally ?
We recommend slip-on exhaust, an air box removal kit, an air injection removal kit, and either remapping or rejetting your fuel delivery system for the best results. Please see our complete performance Weekend Project packages for your bike to get everything else you'll need in one complete package.
