Dial-a-Jet
#3
what is a dial-a-jet? i kind of get the picture just from the sound of it, but how does this actually work, and does it work well? i started to read a bit about jets, but i don't know a heck of alot about them. i put a pipe on my LT and never changed the jet, which i think i should have. how often do you change it? what i mean is, do you change it for winter, summer, humidity changes, altitudes? and how much does a difference does it make?

I'm starting to figure out the skinny on this jetting stuff.But he explains it much better than i can.
Putting a less restrictive pipe on, Enables you to achieve a higher flow rate of air/fuel mix.Therefore you can add more fuel.And it can make a big difference.But tuning carbs is tricky bussiness.Do it wrong and you can burn down the motor.

I found a lot of info here, and from the links off the site. Of course it's all the positive stuff about the dial-a-jet.

TRX430EX,
Yes, you can burn your engine up if it is jetted improperly. A great way to do this is install an aftermarket pipe and not rejet.
Bigdevil,
I would recommend you pull your sparkplug and check the center insulator color. If it is white or light grey you could be headed down the road to trouble. Most manufactures jet a little on the rich side so you might be alright. Anytime you change the intake or exhaust on an engine it is prudent to check the jetting.
Here is a geat link to get the basics down on jetting and reading spark plugs.

Rather than try to explain the Dial-a-jet it is easier to go to there website as listed in one of the other posts.

i have checked my sparkplug. burns nice and tan. the only trouble i seem to be having is when i go to start the bike, it loads up, and floods the plug out alot. but i think this has nothing to do with the jet. i think i am having trouble with the floats sticking. i took the carb apart but didn't see any problem with the floats. checked the reeds too, but they look good. but if i leave it parked with the gas on, it drips out of the overflow. any suggestions, on what to check? no hole in the floats, and they aren't sticking

Corncob is right on the money. For clarity the floats forces the needle into it's seat shutting off fuel flow to the bowl when fuel raises to a predetermined level. If dirt/debris is interferring with a proper seat fuel continues to flow into the bowl. A bad needle or seat could cause this also. These needles do go bad over time.
