Got the Raga 300 and have rode the 290 Cabs. I'm thinking of changing to the Cabs because the suspension and steering were a lot better. However the Power difference between the bikes is massive, the 290 Cabs I thought was a lot less powerful to the point of being disappointing. I've heard of someone altering the ignition timing, which in effect made the bike more zippy. Anyone know how this can be done?
