Hey guys, I'm going to do a quick little video here working on this 2001 YZF250R or F, I'm sorry, and 2003, Kim's shifting it, but when I'm working on it, I set the valves and I'm just really not finding anything wrong and I'm timing to have these hard starting to blame so we're not some checking everything out. So getting into the carburetor here and it cannot stress enough, this one most overlooked place is in a carburetor, the most popular saying that I say in these videos, but underneath your needle valve assembly, or this guy goes, people always take this out and then they quit and that's the problem, okay, you have to take out the needle valve assembly and let's see if you can see this. So this float needle assembly is the type that has a pre filter under it and a lot of people don't realize that this is under there so they clean on top and they clean going to it, they replace fuel filters and you have to service this, it has to be removed and cleaned thoroughly or you're going to have fuel restriction. The other thing that I'm going to be able to see on here, oh there you go, see that, I'll turn all this, see that o-ring, how loose that is, won't work, won't work, absolutely at all. So what's happening here is your float needle, which is your sky right there and then the float itself, when it says, okay I'm going to shut the fuel off, I don't know what happens is, fuel's going to leak right around that o-ring out in and you have raw fuel in here and you have a flooding over filling carburetor. Quick note here because I got some pretty smart people that watch these videos, see that hole right there? Well, that does allow fuel to go around where when it's in its position, it almost looks like a star pattern and there's a relief and fuel will go around there to fill the float bowl faster once that float needle comes off the seat. But make no mistake about it, what I'm talking about is that o-ring seal against the body, a fuel leaks past the o-ring, it's raw, unmetered fuel that we do not wish to have. The fact that the o-ring is not tore, what can happen is that the flooding, if you will, is going to be minimal while you're riding the bike, it's just going to make it run richer than it's supposed to. So I'll have to go back and check the spark plug again and see what I had there and see if there's any clues of that this was just a rich running bike. But without a doubt, float needle and assembly need to be pulled out, looked for those filters, being thoroughly all the way through the track and make sure you're not restricting any fuel flow that you're wanting to get in there. This was my tip of the night.
