There are more new parts coming down the line from Briggs & Stratton Motorsports. The newest and biggest change in a while is the new PVL (Probosch - Vogt - Loos) Ignition system. The new system will include a new flywheel and coil. News from Briggs is the kits will be at the Distributor level by the end of November if all goes well. Rumor has it, they will be approved as a legal part for the WKA Volusia dirt national and will by mandantory by the 2nd WKA dirt national in 2007.
