Re: Carb mods and Clear tube method explained

The lid, even with massive holes do not flow as good as an open airbox without the lid. The Airbox cover will flow better, and you get protection from water and mud, where a lid full of holes will allow water to get into the airbox.

Re: Carb mods and Clear tube method explained

The way I'm reading it you say the fuel in the clear tube should sit 3mm above or higher than the mating surface of the bowl while the FSM clearly shows it to be 3-4mm below the float chamber mating surface.

I currenly have it above/higher and it still runs like crap but that may not mean much.

Re: Carb mods and Clear tube method explained

The Yamaha manual is not correct. Trust me I tried their settings and it is basically impossible to get to their recommendations. You have to cut the float and modify it to get to their recommendations.

Also the manual recommends doing the float high without the clear tube method. If you use those recommendations, you come close to the 3mm above mark I am referring to.

I believe the manual has typing error and it should have read 3mm ABOVE.

Re: Carb mods and Clear tube method explained

The oem and clymer manuals do have some significant errors, some blatently so.

Photobucket is trash now, use something else.

Re: Carb mods and Clear tube method explained

can someone clear this up.. wouldnt this mod just cause the quad to run richer?? and my manual says to set the float hight 13mm from the bowl deck. isnt 14-18mm pretty drastic?

Re: Carb mods and Clear tube method explained

Guys, the manual is wrong. This mod will not make the bike run richer, in fact it might actually lean it out a little. I have personally done this mod to something like 30 different raptors, and all of them gain HP on my dyno. A stock raptor gains around 2HP, just by having the float level set up right. Hundreds of guys on the web have tried these mods, and if done right, they all come back and tell me they felt the gains.

Just do exactly like I explain and you will be fine.

I spent hours and hours trying to figure out on how to set the carbs up as per the manual. the manual itself contradicts the setting. Stop messing with that stupid 13mm recommendation. The clear tube method is the final answer, so donít even bother with the other method the manual explains. Just set it to as per my instructions and the bike will perform. Guaranteed.

Re: Carb mods and Clear tube method explained

I have just one question on this, maybe more by the time I am done typing!! I have done this mod, I did it at the same time as re jetting for my CT exhaust and proflow K&N. Dumb move I think, LOL. I am a little high on the right carb, maybe 2mm high. Question is " after running in the top end of quad I seem to bog and start back firing badly (running out of fuel is my guess ), could this 2mm high on the right carb be causing my carbs to run dry? Once I stop for a split second it starts right up or straightens itself out and is good to go again. It does not do this if I stay down from the top end. I checked for fuel flow from the petcock and flow is good, I also tried blowing through the fuel inlet hose as the directions say but it's hard to know whats normal. Any help would be great, Thanks

Re: Carb mods and Clear tube method explained

The float mod, if done right should take care of the carbs running dry. Make sure you cut the little stopper at the rear of the float at a 45 degree angle. That mod will open the floats a little further and allow more fuel to get in when you need it.

Look at the picture below to see what I mean.

Re: Carb mods and Clear tube method explained

Alright, thanks. I will have to check thing out and see, that's the one step I wasn't to sure about. The whole mod was pretty easy other than the hitch of the carbs running dry.
