Newbie question (yes I checked the FAQ )

Recommended Posts

Brought home a gently used 03 TTR125 for my 12 year old daughter today. Bike is exceptionally clean and runs great. Seems to be a little tough to start when cold, but have not figured out how to persuade it yet. Some questions:

1) I Noticed something that is probably no big concern, but don't have experience with this bike to know better. If the bike is tipped on the left side, quite a bit of gas dumps out the overflow hose. Is this normal?

Thanks and regards,

-f-

My TTR catch can has to emptied after each race. If anyone has a cure for this I would love to hear it. Somedays I think I dump more gas out of the catch can than I actully burn racing.

Ours dumps gas all the time too out of the overflow hoses... I was thinking it was a misadjusted float or something, but this thread has helped me decide it's normal.

As for the slow starting, ours used to be really cold blooded too. After I did the airbox mod, the exhaust mod, and changed the pilot jet it helped out dramatically. The bike is just stuffed up and leaned out stock. Opening it up and going up a size on the pilot jet was all it needed.

It's still a little cold natured, but she can start it by the third kick and not work herself to death.

Do make sure you have the choke pulled all the way out though. It is a little sticky...

Also, did you adjust the fuel screw?

Our's was hard as heck to start until I backed the pilot fuel screw out to 2 1/2 turns on the stock jet. It was only .5 turns out from the factory and would barely idle. After i adjusted it it got better, but I ran out of screw on the stock jet, that's why I rejetted it. When I was rejetting, I did the airbox and exhaust while i was working on it.

It really does run better now...

Btw, congrats on getting your daughter riding. That oughtta keep her out of trouble. :cry:

hey ovrrdrive, since your the jetting specialist... I got a ? for ya :cry:

I did the airbox mod, air breather mod (from ttr125l.com), 110-17.5 jets, stock pipe, fuel screw 3 1/4 out, needle clip set to highest point on needle. Starting isnt the problem, it usually pops off 2nd kick or so. The problem is running it when its cold. After I let it idle for a good 5 minutes or so, and try to take off it dies out. If I can manage to get it going by pushing it and letting the clutch out slowly, it misses skips and bogs untill it warms up. All this can be avoided by just keeping the choke on for the first 3 minutes of ridding. Is this normal? If not, should I go up on my main jet or pilot jet? Thanks man

I'm glad you said that with a smile on your face. :cry:

Before a few months ago, I had never even taken a carb apart on a motorcycle. I even paid someone to jet my streetbike...

After jumping into it though I found out it wasn't that hard and it intimidates so many people so I just help out when I can.

As for your problem at hand, ours is the same way. And we handle it the same way as you too, by riding it for a few minutes with the choke on. I'm thinking these motors just take a few minutes to get some heat into them.

If it is running good when its warmed up I wouldn't worry too much about it.

Specialist... You're killing me! :cry:

Glad I could help out though. :cry:
