Petcock rebuild worked awesome

I will beg to differ with you there. I have been using OEM rubber gas lines in all of my Suzukis for the last 12 years or so, and have had NO problems with them.




Depending on your filter, that might be your problem. If you installed an automotive-type filter, remove it. If you feel that you absolute HAVE to have a third filter in the system (gas already goes through two filters before getting into the float bowl), get one that is designed for a lawn tractor.



Adding tension to the spring definitely did not help, but don't bother trying to get the air bubbles out of the filter, they are not hurting anything. See my comments above on filter selection.

I think I have one for a lawn tractor. It's a 5/16" in/out clear paper filter. Are you talking about the petcock screen and metal mesh screen in the carb needle and seat? That's not really a filter for the finer stuff. The reason I want one is because this tank had a lot of rust in it. I used pho acid to clean it out but I'm still catching rust particles in the filter. I will keep everyone posted and thanks for the advise.

Can't tell by the description whether it will work or not.

The difference is that most automotive-type filters are designed with a fair amount of restriction, because they will be in a system with a high-pressure fuel pump that will push fuel through the filter media. Since our bike only have a gravity-fed system with a few inches of head height, those filters simply will not flow enough. A filter for a mower is more likely to work with a gravity-fed system, as long as the mower for which it was intended does not have a fuel pump.

Problem with those inline filters is that they are designed for systems run by a fuel pump to supply a pressurized fuel line. Our gravity feed systems arent intended to be impeaded with an inline filter.

Well I fixed the bike so far. I think I figured out my cutting out was crappy plug wires. I cut off the ends and screwed the caps back on. I also adjusted the fuel filter where it laid horizontal and now I don't think I have starvation issues.

The filter should be standing VERTICLE with the end feeding the carbs pointing down...stops an air pocket from forming right where the line and filter connect. Like set it right at then top of the rack between 2 and 3.

I wish that were possible but it's not with the filter I have. It's too big. I have been keeping an eye on it and the filter stays mostly full except the top 10%. But both the inlet and outlet stay full. I think my major problem was spark dropping out because of weak connections at the spark plug boot.
