Re: My GZ 's top speed seems low
There are only a couple of hoses on the bike.
Someone correct me if I am wrong, cause I'm just going by memory.
There should be 2 lines running between the gas tank and the carb. And 1 or 2 between the crankcase and the air box.
That's it, unless I missed one. So you basically just check that those hoses are connected and snug and that the rubber isn't degrading.
That being said, if you aren't getting any rev lag, popping on deceleration or crazy bucking while trying to accelerate, then you are most likely ok. It's good to give them a once over every now and then though.
Try the seafoam. These carbs can be persnickettey with even the tiniest amount of debris in there.
Also, slosh the gas tank around a bit. I know this sounds ridiculous, but those petcock screens can develop a varnish that will impede gas flow.
Lots of little things to try.
