Question about 2003 Yamaha V Star Classic
I have a a yamaha VSTAR 650 and I just bought new vance and hines exhaust pipes and Installed them. I have not yet rejjeted the bike but I am going to in a couple of days. I was wondering if it Will hurt my motorcycle if I ride still without rejetting until then?
No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.
