setup for a ttr125

 

for a 06 ttr125LEV
Yamalube 20w-40 or some other oil

seems to run a bit lean... Tis a tad cold here so I'll
check into this when it's a bit warmer..
I wondered if the factory jetting is close or
is there a jetting kit that folks slap on there

on the list is give it a good cleaning
<spark arrestor included>
tighten bolts lube anything that moves
replace anything that looks warn, but the quick look
over I'd say the bike wasn't Manhandled too much
and shouldn't require much to get it into girl standard
of maintenance <my stuff I don't mind walking, but I'll
be darned if an equipment failure is going to give the ladies
a bad riding experience...> more stories & questions
to follow up as I tear into this weekend

They run really lean, hard to start as a result.
I haven't tried a kit on mine, raised the needle a
notch, 112.5 main, helped after it's warm but still
cold blooded. I just live with that as it runs great
warm.

The enrichner can seize too.  Cable feels like
it's working but the plug in the carb that it
pulls isn't really moving.

Tall seat kit and Jimmy Button (tall) bend bars
are the best thing you can do to it though.


Go fast. Take chances.

Tall bars sound like a nice feature...
this is primarily a wife/kid bike.. both are 5'4" ish
other kid is 5' and rapidly growing
<dang kids these days>
i hope to open up the carburetor in the next
few weeks and see what's in there,
the bike looks low hours..& fun

This is my 12 year old's bike, he's 5'3" and loves
the tall seat and bars.

TTR125s are lean on the pilot and needle but rich on the main from the
factory.  First cut open the airbox and do the washer mod on the pipe
insert (just to make it sound a little like a motorcycle and less like
a sewing machine.  Start with the stock 105 main.  You might want to
bump it up to a 107.5, but a 110 was too rich on my bike.  Change out
the stock 15 pilot for a minimum of 20, and lower the needle clip to
the bottom if you have a 3-slot needle.  If you have a single-slot
needle, make a shim to raise the needle twice the width of the needle
groove.  Even with a 20 pilot, my TTR required only about 3/8-1/2 turn
on the air screw (22.5 might be a better number), however, my bike
will now stand straight up with a just a crack of the throttle.
