Malossi 210 with HRS high compression head, HRS Vortex 33, Mazz cut crank, ScootRS pipe, Cosa clutch with MMW Cosa basket, Non oiler, VNA 8".
I bought the MMW cosa basket through SIP as i am trashing my standard cosa baskets. I thought this would help as $100 baskets are expensive to replace every 2 months. I did grind out the clutch bell (lid) pretty good, so nothing from the basket is rubbing. Here is my problem: When i am at idle at a stop light (or just stopped), i put my bike into gear and take off. I get the unholy grail of lurching. I only get this "lurching" when i'm into 1st gear. When i shift into other gears or downshift I don't get it. I have tried two different spacers (between clutch and bearing), the geared spacer and the thinner style from teh 1960's. Switching out both spacers did not effect anything, same problem.
