When y'all say drain the bowl, how is that done ?
I have not looked at diagram of the carb but I'm assuming the bowl is on the bottom. Does it come off fairly easily or is there a trick to draining?
Yes. The bowl is on the bottom, and the drain is the little nipple, that comes off the bowl. There is an allen head screw right next to the nipple, that you loosen to open the drain. An allen socket and an extension, reaching thru from the left side, will let you loosen the screw. Don't over tighten it when you snug it up again.
Shine your light in from the left side, there by the fuel pump, and all will become clear. I use a small piece of clear poly hose pushed on the nipple, to get the fuel away from under the motor as it drains. Once its open, and drains, you can turn the key to on without starting the bike, and the pump will push fuel thru the bowl, and rinse things out good.
Turn the key off. Snug the bowl screw. Remove the tube, and your finished.
