Raptor Adjusting floats to the right level.

Hey I want to check if my floats are off and I'm sure they are because I took the carbs apart at least 3 times. I need some instructions on how to fix them so they are on the right level. I dont know how you check them exactly. Someone told me but I need specific instructions like where to measure from exactly.

Check the carb sticky for adjusting the with a piece of clear tubing.

On the bottom of the carbs you'll see a small black tube, pull that tube off and connect a piece of 1/8" clear tubing to it. Bend the tubing up next to the carb with the other end facing up (J) kind of like that. Loosen the drain screw next to where you hooked up the tube and gas will fill the tube, where the fuel stops in the tube is where your fuel level is. It should fill the tube and be even with the seam between the bowl and the bottom of the carb body.

The clear tube is the easies way to check the floats. I just went thru the same thing last weekend. When I checked my raptors float levels they where 5 mm above the split. I set them to be on the split. Some people and a couple of Yamaha dealers say they should still be lower. 2 mm below the split was recommended to me by a guy that dyno raptors. The Yamaha manual say 3 - 4 mm below the split. I still don't know who is the right.

Another problem I had was that I could not get the floats to drop to the right level. I had to modify the little stopper on the back of the float. I got a file, and at a 45 degree angle removed some plastic from the little stopper. Now it does open all the way.

Another way the manual recommends to adjust the floats is by taking the carbs out. Remove the little bucket at the bottom of the carbs. If you turn the carbs at a 45 degree angel the floats should rest (just touch) on the needle valve. It should not compress the little spring in the needle valve, JUST touch. You will see when you move the carb between upright (normal way they are mounted) to a 45 degree angel they will stop moving when they touch the needle. When that happens measure it. The distance from the split to the top of the float should be 13 mm.

Now there is one thing that bothers me. Will the floats always read the same with pump gas? No matter what make? I am not so sure. The clear pipe method is therefore the best way to set the float level.

The best is download the manual on this forum. Then when you have it check section 7. They explain it real nice. Both the clear tube method and the other way.

You guys are just confusing me more. Someone post some pics because your talking about like 45 degree angles and stuff. This isn't complicated but I just dont want to mess it up. When you adjust the floats, what exactly to you take apart and when you say like names of parts, tell me what they look like so I have an idea. Like the plastic things, do I have to take them off to adjust the floats ? See I have no idea how to do this and you guys are just confusing me more.

Sorry it may sound confusing. The best is to download the raptor manual from this forum. Check the raptor section, its a sticky at the top. This explains most of the things you need to know.

I don't have a digital camera, but will get one this weekend when I do the jets...so ill take some pics of the float levels and how to use the clear tube methode.

Its actually very easy to adjust it, but it takes a long time. You need to strip all the fenders of the bike, remove the airbox, then the carbs... and maybe some cables to, depending if you are happy to adjust them on the bike or not.
