People 50 / Re: Keihin Main Jets
« on: December 19, 2010, 10:16:24 PM »
I received the Jets, they were correct, and fit.

I installed a 38 Pilot Jet and a 90 Main Jet.

I adjusted the mixture with the air screw after it was warmed up.

Set the air screw at about 1-1/4 out.

Starts much easier now.

There was a little bit of a stumble in the bike in the midrange until it got warmed up.

Runs fine, looks like i'm all set until the summer comes back, then I'll probably drop the main jet to an 85.

We will see.

Hey oswaldters-

Once I get the jets, I'll go ahead and post my findings about the fit.

I'm almost positive they will fit since I did the micrometer measurements myself.

Either way, I'll let you know.

Cheers-

My 2005 People 50cc 2 stroke has a Keihin carb.

I pulled the Main and the Pilot jet, and got out the micometer.

According to my measurements these are the series jets that will fit.

MAIN JET
OVERALL LENGTH = 7mm
HEAD DIAMETER = 5mm
THREAD MAJOR DIAMETER = 3.9mm
KEIHIN 99101-116

PILOT JET
OVERALL LENGTH = 28mm
HEAD DIAMETER = 5mm
THREAD DIAMETER = 4.9mm
KEIHIN N424-74C

These are availbale at the following web site.

I hope this helps anyone looking to re-jet your bike!

Colder weather, and I want to fatten up the Main Jet on my scoot.

Anyone know where to get my hands on a 90 or larger Main Jet for a Keihin for this 2005 People 50cc 2 Stroke?

Thanks-

I wanted to fatten up the jetting for the cold weather-  I think I have an 85 Main Jet in there now.

Anyone know where to get my hands on a 90 or even a 92 main jet? I think the carb is a Keihin.

I put in the Auto Choke unit.

Found it for about $20 new at Monster Scooter Parts. Kymco wanted $60.  F- that.

Monster Scooter Parts
800-798-0325
Part # P33-4092 Automatic Choke for 50cc 129QMB and GY6 Carbs.

Plugged it in , bolted it up to the carb, and kicked it over, fired right up.  It's in the 30's right now too!

FIXED!

That's what I thought.

Anyone know how to hook up a MANUAL choke to replace this AUTO unit?

OR- does anyone have a carb they would part out?

The carb is a KeiHin

I have been suffering from REALLY hard starts and stalling until the scooter is warmed up.

The bike is a People 50 2 Stroke.

I finally pulled the Auto Choke unit and tested the resistance with an OHM meter.

Results are 0 resistance, it pins the meter when you hook up the leads.

This leads me to believe that the unit needs to be replaced.

Is there an other empirical way to test if the auto choke unit is functioning before I spend money on replacement parts?

Last question- where can I find a replacement part source online?

Thanks-

Matt

Since I'm here in TEXAS in the heat of the summer, I'm going to opt to not reconnect the preheater hose!

I'LL BE LETTING IT DANGLE!

OK- got it.

What course of action should I take in order to correct the problem and get the air screw where it should be sitting?

I do not want to risk the possibility of a lean carb setting.

So open up the air box?  I thought I would need to bump the pilot jet up instead, since it's lean.

Wouldn't opening the airbox lean it out even more?

Had some trouble this am with stalling at the stop lights.

After re-installing the stock jets- not sure what size.

It has a real cold blooded tendency off the line as it is- which leads me to believe it's the pilot jet.
So- I adjusted the air screw.
I was able to stabilize the stalling by screwing the air screw all the way in.   It's still a bit flat off the line until the main jet takes over and the expansion pipe powerband kicks in.

All I did was add the Leo Vince unrestricted pipe- did not mess with the air box yet.

Would this affect the pilot jet?

Screwing IN the air screw indicates the need for a larger pilot jet, correct?

Should I bump the needle up a notch or would that not affect the low rpm/ throttle flat spot and stalling?

I have a black flexible tube about 3/4" in diameter that comes off the left side of the head shrouding. Where is this supposed to go?
It's a bit kinked, because it looks like it got melted a bit.
Should I replace it ?

Once the # 85 shows up, I'll pop a couple holes in the airbox and see what happens. Is there a proven diameter that gives better flow, without over doing it?

Trying to ride stealth by keeping the noise down.

You don't realize how much noise intake cones add to the dB level!

I like my neighbors, and they like me, and I want to keep it that way.....

Ok- great.

I ordered up an #85 main jet.  I'll leave the pilot as is for now.

I'm going to have to wait until that bigger main jet comes in before I start messing with the airbox, I don't want to lean it out too much!

Other than that, I'm putting it back together, and going to ride it.

BTW- I popped the Spark plug out when I got home last night to take a look- looked nice and tan, no evidence of a lean condition.  This was not done with a throttle chop- just wanted to eyeball it.  Should I be concerned about a lean condition with the addition of the pipe?

Cheers-
