I just picked up a TTR125 dritbike and it runs well but the tubing from my carburator is leaking. looks like over flow tubing. Maybe a seal/gasket


It leaks even when the bike is not runningm and the gas is turned

what do you think it is?

I know the carbs may be different but whenever this has happened on a Harley (and it happens way too much) its usually a stuck needle.

If the bike has been sitting before sale I'm betting a little carb cleaner in the right places will end it.

I was told that they didnt use it much and kept gas in it for a long time. The bik looks like it has very little use.

carb cleaner where?

you mean one that you pour in to the gas tank?

Or, taking it apart and spraying it down?

It is the carb float.

Here are the options-

Float has a hole and is fulle of fuel.

Needle is not seating properly.



Try tapping on the float bowl with the handle of a screwdriver. Sometimes that knocks the float loose. If not simply pull the carb and rebuild it.Very simple

it is the float needle sticking, and letting more fuel in than needed.

Take the carb off.....might as well give it a good cleaning while you are checking/setting the float height.

should fix it.

Needle valve or float, maybe float level is off, and petcock needs to be rebuilt.

check to make sure its not the carburetor drain tube. There should be a little screw on the back of the carb connected to one of those tubes.

Won't do a fucking thing.

It's the float, trust the good advice given and fix it. It's not hard to do, it's just basic bike stuff all owners should be able to do.

More than likely caused by ethanol fuel. It loves to gum up the brass parts inside your carb.

unlike the prior owner I put stabile in all my gas cans



looked on ebay and the rebuild kit costs 38 dollars and so does a new aftermarket carb

Minkuni Carb is 125 bucks...I think these are the ones used on the original bikes

should I just buy the aftermarket kit and rebuild the current one as a spare?
is the aftermarket carb junk or will work just as well?

You likely don't need a new carb, or a rebuild kit. I'd bet my paycheck a good cleaning and inspection, possibly a cheap float valve at most will fix your problem.

Start with the video above, take your carb apart and clean and inspect it....check the float valve and the float height. Clean the jets and the passageways with carb cleaner and compressed air, assemble it and see how it runs.

If you wanna really be proactive, take the jets to your local Yammie dealer and get a new pilot and main jet....but probably not necessary.

This.....

Also, the o-ring on the float needle valve seat is probably cracked, fuel will get past it even if the float is closing the needle.

have 3 days that I'm back from work this month and want to take it riding. dont have time to take it apart and play with it then put it back to see if it works... to frustrating. Would rather buy another one for 38 bucks and take my time playing with the original one and have spare parts. I just dont know if the 38 dollar aftermarket one will work well or if I should just buy the 115 dollar minkuni

Dude it would take an hour, tops, to clean your carb and put it back in there.

Do you want to keep asking questions until someone tells you that your plan is the best one?

Ok, permission granted to dump some miracle fluid in the tank and buy a new carb. I'm sure it'll be jetted correctly and require no adjustment to the fuel screw or needle to be back to perfect that will take away from your riding time.

If its that easy to do then I'll give it a go. unfortunately if I need a replacement part and the stores in my area dont have itI'll have to wait another month to go riding with my GF

swing set is right..

i will add to do this and give it a try first before you shell out a bunch of cash.

turn off fuel petcock.

start up engine and run it out of gas.

open fuel petcock.

start bike and then close fuel petcock.

run engine out of gas.

open fuel petcock.

start bike.

turn off bike and see if whatever was making the float needle from closing properly flushed itself out and into the bottom of your float bowl.

much luck....

There's a drain screw on the bottom, just open it and let it run into a container.....

You should do that before taking it apart anyway, but it's not going to fix anything.

Have you tried praying?

Adjust your float height. Seriously, 5 minutes maybe? 2 screws? I tweaked mine half a dozen times yesterday in under an hour.

You could watch the video I posted above, and probably avoid your next 3 or 4 questions.

Probably your float. I don't know about your bike, but some systems have a PRIME setting on the petcock, make sure that yours is on RUN and not on PRIME.
