2002 Honda XR 400R Questions & Answers
Wont stay on without choke
Pull the carb, remove the float bowl and air and throttle screws then soak the carb in denatured alcohol for half an hour then clean it with spray carb cleaner. Spray into every little hole in the carb including the air and throttle screw holes and the tiny drill holes in the throat of the carb.
LIGHTLY seat the air and throttle screws then open each of them one and one half turns. Move the clip on the jet needle downward one notch then put the slide back in place.
Please rate my solution. Thanks.
2002 400XR hard to start and will only run well with choke on
hello
it sounds like a jet has become plugged. the popping is generally associated with a lean condition. in your case it seems the pilot jet is plugged. this is very common because the pilot jet is a very small orifice and is apt to plug and cause bad low throttle or idle conditions. removeing the float bowl and takeing out the pilot jet and cleaning it or replaceing it should solve your problem. this also will help with the cold starting conditions. thank you.
Xr400r's been stood a while,
Make sure the carb is thoroughly cleaned, all jets not just main. The half choke is compensating for the slow circuit jet. Check your air/fuel mixture. Also, check the air and fuel filter. If all checks out fine and you still encounter the problem, could be : bad gas, wrong spark plug heat range, or most likely the diaphragm for the top of the carb.
I need to know how
On the right side of you motor, there will be a sight glass.
You will have to crouch very low, and possibly lay on the ground to see it.
The sight glass is in the right side cover towards the back and at the bottom.
If your oil is in need of changing and has turned dark in color(black). The sight glass isn't so visible when the oil is black.
Thats how you check the oil level with the bike off the kicksatnd and you holding it staight up, while looking at the sight glass.
I have a Honda XR400
I have a 2003 XR 400 that I bought in 2005 nearly new (seller was more of an MX guy than trail guy). Thing was HARD to start no matter the conditions; hot day or cold day, sea level or 7000', dry or wet. Once I tired myself out completely and got it running, it would restart ok, but still always a challenge. After months of gritting it out, I followed the advice of everyone online. I bought a pumper carb. Don't even screw around with getting just the right jets, or all the other stuff you've already done. You bolt on the carburetor that the bike should have shipped with and you'll be one or two kicks from a nice run/idle/ride. I ride literally from sea level to 5000' with zero issues. I ride at 7000' no issues. Seriously, It was the best ~$350 I ever spent.
Where is the oil filter
On the front right corner of the motor is a round cover held on by two bolts (one short ,one long). The oil filter and spring are under the cover. Be sure to only use JASO MA motorcycle oil . 0w-40 Amsoil synthetic oil works great in your model.
Hard clutch-
Half the time the problem is the cable due to lack of lubrication. Try adding liquid graphite (lock Eze) into the cable. Check for kinks along the length of the cable and bad routing of the cable. The other half of the time the problem is very dirty oil in the gearbox. Try an oil change.
Honda PC50 moped VIN decoder
To read the serial number on a Honda PC50 moped, follow these steps:
Locate the VIN (Vehicle Identification Number): The VIN is a unique code that provides information about your moped. On a Honda PC50, you can find the VIN in the following places:
Under the Air Filter Cover: Look on the left-hand side, just above the engine. The VIN should be stamped there. It typically looks like this: PC50 - 1234567.
Frame Number: The frame number is another term for the VIN. It's usually located near the air filter body.
Decode the VIN: The VIN contains important details about your moped, including the year of manufacture. Here's how to interpret it:
The 9th digit of the VIN is a check digit.
The 10th digit represents the year code. For example:
A = 1980
B = 1981
C = 1982
D = 1983
E = 1984
F = 1985
G = 1986
H = 1987
J = 1988
K = 1989
L = 1990
M = 1991
N = 1992
P = 1993
R = 1994
S = 1995
T = 1996
V = 1997
W = 1998
X = 1999
1 = 2000
2 = 2001
3 = 2002
Note that if your scooter was manufactured between February 1986 and February 1987, it's likely to be a '87 model;
Additional Resources:
If you have the full VIN, you can use the NHTSA VIN decoder to get detailed information about your moped.
Alternatively, you can call Honda with your VIN, and they will provide you with the necessary information.

Honda 500 TRX fa6 has PS on the dash….what does it mean ?
The Power Steering has failed. There has been a factory recall for a suddenly failing electrical steering shaft, that could cause the rider to loose control. This does not have to be your problem but anyhow either the electronics or the pump failed. Error codes or messages usually have to be erased by a simple reset procedure or disconnecting a plug, after repairs are done.
