Today I started up the bike. It had been sitting for a couple months and one of my friends said I should press the starter a couple of times to get the oil circulating before actually starting it. After pressing the starter 3 times I got a loud back fire out of the exhaust. Bike started up when I pressed the starter again. Should I not do that? I'm assuming I either over fueled the motor or compression got to high. Do you think any damage was done? I'm not too sure what to do when I do leave the bike sitting for either winter storage or just don't have time to ride... I'm assuming the motor is pretty dry so start up is harsh
