Although this isn’t a specific tip for the AG200, I think it is relevant to mention it here. Like most factory internal fuel tank filters, the AG200 uses a plastic gauze which is not real effective at removing rubbish from the fuel. The generic in-line filters from motorcycle and carburetor accessory stores are barely better than nothing as well.
So think of an industry where maintenance is not on the radar…something that only tends to get looked at when it goes bang or stops running for some other reason. I’m thinking lawn mowers! They get virtually no maintenance from the average user so the motors and ancillary parts have to be basic and withstand serious neglect!
So I thought I bet the fuel filters are a bit more serious than your average bike fitment, and I was right! Check out the filter in my pictures and you will see its not pretty, but that suits the AG! It has way more filtering area than the proper bike filters and the medium is finer so it will actually keep rubbish out of the carb as intended. You can see water and dirt accumulate in them as the fuel flows from the outside into the middle, so what it filters, you can see. A great visual aid at service time.
The AG200 first made an appearance in 1984, so some of them are getting some serious age on them now. I doubt there are many still alive from this period any more, but the neglect they receive means if you do acquire one, you will have to keep on top of maintenance items like this to stop the headaches. I also think that if a decent filter was fitted from new, then maybe we wouldn’t see the emulsion tube (needle jet) wear issues that we find so common here.
The filter that I use is a FPL5553 from GA Power Equipment Spares. Just drop into any mower shop and ask the parts guy to have a look at his filters. Maybe take your fuel line in with you to help him out a bit. Any thing with a paper element will do, the AG200 sips fuel in standard form, so the flow rate is probably less than most mowers anyway!
Remove your fuel line from the bike and you will have to remove a few centimeters from it (I take out 3cm) so it all fits neat between the tap and carb. Removing the line facilitates fitting the filter because it can be tight installing the rubber line (especially with it freshly cut) and painful while trying to do it on the bike. Some silicon lube might be helpful in this case, as can some warmth on the rubber line.
So there you go, a simple mod that will keep you happy riding without worrying about bad fuel ruining your day. Keep an eye on the rubbish in it, and you will be able to keep the fuel up to your bike and help it run reliably and hopefully avoid carby contaminate problems.
