Use a DYNAJET kit & go with the directions. Or check with the Hypercharger manufacture for correct jetting. But you will still need different needles & main jets for those pipes.

SOURCE: 2007 650 yamaha vstar popping through the rear cylinder exhaust

First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.


Bring it to a shop & have it looked at.......


Good luck

SOURCE: have installed hypercharger on 06 roadstar. lost

Take the hypercharger back off. The carb uses fuel according to how much air sucks through. You are putting alot more air through the carb, so it sucks more fuel into the engine. Even if your not burning all the fuel, it's running through anyway. That's the downfall to a carb.

SOURCE: 04 yz250f pipe at motor glowing red hot

Any reason you had to change the jetting??New pipe,Intakes.?But,even though you may have it a bit rich on idle the pipes WILL get very hot,very quickly without some sort of air flow over the front of the motor and radiator.At the very least,have a strong fan blowing directly on the front of the motor if you are going to let the bike run and you are not riding it.I have seen the white plastics in front of the radiator distort from the radiant heat.Don't idle them for in more then 20 seconds.It can do heaps of damage.Ride the bike and see if its running well.When you stop,turn it off.All the yz and wrf will get very hot at idle.Hope this helps

Just bought a 2001 WR 426. Has an FMF pipe, no air box lid. Main is a #165 and pilot is a #42.these are stock jets according to shop manual. My elevation is 2500-3000 Ft. Any ideas on jetting?

Hard to give accurate info with out seeing the bike with jetting but I would suggest take a reading from the fuel air screw if the bike running better with the fuel air screw in carbi at 2.5 turns out or more then definitely increase pilot jet up 1 or 2 sizes if you get the bike to run well between one - two turns out on the fuel air screw that is where your jetting should be
I wouldn't be concerned with main jet at all - it should be fine for wide open throttle unless you feeling power loss when you open it right up
also if you are getting backfire or popping when de accelleration that also hints toward lean pilot so a size or two change in pilot jet would be worth trying

I just rejetted ( at least I think I did ) my carburetor on my vstar 1100 custom. The problem is that the Cobra Carb Jet Kit 92-2170 only had main jets.... five of them. Does this mean that only the main...

In many case when you rejet your carburetors you are only changing the mains and the needles(to get rid of the acceleration bog) If they give you several size jets to try, be sure you are putting the right sizes in the right spots. Yamaha typically will run one carburetor leaner than the other. Depending on how the cycle is running , I have known people to match the jets in both carburetors. Check the color of your plugs to double check if you have set the cycle up correctly.

What should the stock carb jets be for a 94 yz250 with the stock pipe and aftermarket silencer

Stock Jetting for a 1994YZ250 is:

350 main
45 pilot
J8-6EJ33-61 needle

Adjust your jetting down one size for each 1000' of elevation above sea level. Needle clip position on the needle fine tunes the pilot circuit.

Gas heater never kicks on above unit/pilot on situation

Hi Imconfused,

Usually with gas Heaters the main problem is a blockage in the jet. They usually blow them out with compressed air. This can be done from the top near the flame and with luck it will clear it. If not then you need to go looking the main pipe to the jet which will involve removing the outer covering to get to it. Remove the pipe and blow it out and blow out the jet too. Make sure you put the pipe back on properly. Hope this helps.
