I cant take this crap anymore the dang think wont wheelie like it used to before i jetted it man i just wont. I got the floats set perfect if they were any higher they would dump gas out they are good

but when i try to ride a wheelie it spudders and falls and after it hits the ground again it had to have a moment to clear up then it will go again

but before jetting man i could wheelie all day stand on the grab bar and just lean side to side going down a highway all day long i could ride one ALL DAY LONG but now not anymore

i really need help im so dang man about this i just want to rip my pipe off and stick the stocker back on and change the jetting

any suggestions help help help help

 

well its clearly not the right jetting if it starts sputtering like you say. or you have some other kind of problem like the needles.

 

What jetting are you running?
needle and clip position?
and pilots and mixture screw position.......

I had NO problem with wheelieing after jetting........it actually got easier cause it had the power to pull it up in 4th gear.......

 

155/160
gyt-r needle
3rd clip position
#25 pilot
mix is 1.75 1.75

open exhaust no s/a

 

That's your problem. Your float level is to high.

 

sounds like your float level is too high......the jetting sounds about right.........

 

There will be a 50 cent charge added to your account for posting this again for the fifteenth time.

This is the best way.

The best thing to do is check it before you take it apart, with a piece of clear tubing. You can get the tubing at a hardware store for 20 cents, 1/8" clear tubing.

The quick & easy way to check float levels is to use a clear tube that fits the dump hole on the bottom of the carbs. You'll need at least one foot of tubing. Don't worry about an exact fit, the tubing can be a little bigger which will cause some of the gas to leak out but gravity is forgiving and is constant! You can get the tubing from your Yamaha dealer for a few bucks. Remove the stock dump hole tubing, put the new tubing on there & then bend up the other end and run it along side of the carb with the open end facing up. Then open the drain screw next to where the tube is connected & the level of gas in the tube should fill up & be level with or slightly above the bottom/top half of the carb's mating surface. If not, you'll need to adjust the float levels. A sign that the float levels are too high is if the stock drain tubes leak gas while your riding, you'll smell it for sure.
I just pop the carbs on the boots and set the tank on the frame and hook up the hose to check it again, you may have to take it back off once or twice to get it perfect. I also measure the amount that it is off and then take it apart, measure the float height and then bend the tab enough to raise or lower the float the amount that it was off. If that makes any sense.

 

could have i left a clip off of the needle or maybe just forgot to do somthing and what is that little mainjet that is in one of the carbs and not in the other

 

man i have adjusted them where they are at the peak of pouring out i set them high and then back the off just a fraction enought to keep them dumping fuel out

 

another thing does my jetting change that much since i got the stage 1 cam and adjusted my vales to the spec sheet
