QR Code Link to This Post 1989 Yamaha YSR50 with lots of upgrades. It's a 50cc street legal motorcycle with a clean Florida title. Starts and runs very well. The cylinder was sent to Team Calamari Racing in California and was ported for more performance. They also honed the cylinder and it has a new Yamaha piston and rings along with a balanced crankshaft. Team Calamari 24mm flat slide carb, K & N air filter, with performance reeds and 1/4 turn throttle. Team Calamari complete exhaust system. Performance clutch and spring kit. Oil pump block off kit was installed so it's a premix gas/oil engine. Team Calamari swing arm bushings and the front fork spring kit was installed. Two new Michelin Bopper tires with new chain and sprockets. Aluminum racing clip on handlebars and a temperature gauge were installed. The stock battery was replaced with a lithium battery. The seat assembly and lower fairing are fiberglass racing panel. The bike has less than 500 miles on the engine and tires since the work was done. Mechanically it is ready to go. The only thing it needs is a paint job or leave it as is. Let's block ads! (Why?)
