Hi,
I've got some questions about the petcock on this 1990 CBR:

1) Which way does the arrow point for ON, RESERVE, and OFF?
2) Do I need to turn it off whenever I turn the bike off or can I just leave it on?

Thanks,
Barry

 

If my memory serves me correctly, UP=ON, LEFT=RESERVE, DOWN=OFF....and yes, if the petcock works it should be turned off when the bike is parked.

 

Uh.

UP= ON. In the middle = OFF. DOWN= Reserve. My bike still has the sticker on the uppers, so I'm pretty sure about that. It is always possible that you don't have a stock petcock, so the best way is to take your tank off and find out.

Yes, turn it off when you're not riding. That's what it's for. If you don't, there's a chance the gas will seep into some places in the engine it's not supposed to go. (Through the intake, past the rings, and into the oil.)

 

I'm pretty sure it is the stock setup. The "handle" for the petcock is black plastic, about 2" long. I don't have any of the stickers on mine, that is why I wasn't sure.

I think I've already had that happen. When I went to pick the bike up they had put in a new battery but had not charged it yet. While jumping it from a truck, I'm pretty sure the former owner flooded it out several times. When I got it home the petcock was in the DOWN position. When I checked the oil I could smell gas. I'm going to change the oil before I ride it. Hopefully I can find a filter at WalMart.

 

Where's the cheapest place to buy a new petcock (with handle)?
