Is there a vacuum line from the carb to tank?
 

Hey guys so my petcock is leaking and theres nothing I can do about it cause its riveted on and I have an extra petcock from a 97 cbr900 that needs a vacuum line unlike the f3. So question is, anyone have a solution for this?

Thanks
Justin

Get a used tank and petcock from ebay. Or plug the vac line on the 900 petcock and see if it works. Good luck

Plugging the 900 petcock won't work.
Running a hose off of the #2 carb manifold should though.
I say #2 because it should have a capped nipple already on it.

Hey ern thanks. Where is it located? Its on the outside of the block yeah?

At about 7 o'clock on the intake throat
Shine a torch into the area you should be able to see number 2 quite easily

Carbs/cylinders are 1-4 left to right.
The ports are just below the carbs.
#1 usually has a screw cap in it.
#2 should have a nipple with a teeny-weeny hose clamp on a rubber cap.

Best do this when the bike is cool. It gets pretty toasty in that restricted space.
