Is the line a standard size that I can get by the foot at the local auto parts store?= of do I have to have the special Suzuki flavor?
Sorry if this is a duplicate post. I thought I posted this question last night but didn't see it here this morning....and I am tired and my brain is not working wll yet tis morning.
So, the bikes running weird, and you have no indicators that the vacuum line is bad, and, the petcock is notorious for causing weird problems. You can go to the Tech section and test the petcock.
Or, just try putting it on Prime.
Pull the fuel line off of the carb, put it on Prime, see if you have fuel flow.
If so, switch it to Run, the petcock should stop letting fuel through.
Then, if you start it, the gas should come out again. That's probably not recommended. Only someone who knows how to be careful with a running engine AND a fuel leak,,, so, if you do it and burn it down, I didn't say do it. I Did discover how far it would go with the fuel line disconnected accidentally. The bowl on the carb holds enough gas to get it fired up, helmet and gloves on, up the drive, and down to the stop sign.
When did it start acting up? I mean, have you worked on it, or was it right after getting gas, anything you can blame it on... And, if it's a few years old, test or replace the petcock.
