xr80 wont run =(

[Disturbed1331]

I got an xr80 a few months ago as my first bike and it seemed to be fine and all of a sudden it just won't run.... :bang: :bang: i can get it to start but it only runs for at most 5 second then stalls out... i have no clue what to do... im trying to fix this bike up so i can sell it to get a new one. and need it to be in decent conditon..any ideas?

 

[wornknobby]

do you have spark? fuel? obstrution in carb or fuel hose?

What year is it?

If it's older than a 1992 change the points and condensor.

If that doesn't work or if it is newer than '92 clean the carb.
Probably a pluged pilot

 

[Disturbed1331]

hm i think its a 97 or 96. um im not sure what points or condensors are...=( ....but...anyways could i buy them? are they expensive? or what?

STOP! Before you do ANYTHING else back away from the bike and go get a service manual for your bike. The above post indicated this is THE most important item you will spend money on and will save you a lot of heartache, time, frustration and money. As an added bonus you can let it go with the bike when you sell it to show you were serious about maintenance or at least trying to be which is a selling point. Once you get the book you will have a trouble shooting list to work your way through to get your bike running again.

If your bike is 1993 or newer you have CDI so cleaning the carb is the first point of interest.

XR100 its '92 and newer
You don't have points or condensor if it is a '96 or '97
Your carb probably needs a good cleaning.

My XR had a fuel filter screen near the fuel off/on switch (petcock). Make sure that is clean as well. May not hurt to take you tank off and flush it all out and start with fresh fuel either. There could be a lot of sediment in the tank or who knows what in there.

Is your exhaust plugged? I have seen hundreds spent on a bike that was only plugged with carbon...

Disturbed.

Most likely your pilot jet is clogged. Your new service manual will show you how to access it. :cool:

 

[Disturbed1331]

well...the exhaust isn't pluged... hmm im going to go get the service manual and try to unclogge the pilot jet like ol'89 suggested.

 

[Disturbed1331]

It was just that somehow the sparkplug kept fouling. It was to close together so my grandpa fixed that. and we tuned the carb. and it was going really good. i took it for a test drive and....how ironic...a cop pulls me over..and writes me a ticket.......... and i JUST got it working.... man..that sucks..

 

[Patman]

Here's another really good suggestion. See about joining a local club, I know Houston has a few off road clubs. There you will meet people that will be happy to help you learn about your bike (they too will push a service manual) by doing the work yourself with some supervision and maybe tool help, as well as LEGAL places to ride where you won't get a ticket.

 

[Disturbed1331]

yea im looking at going to this place called shighlow (i dont know how u spell it..) and its like 85 miles to ride and there is atv's dirtbikes jeeps all kind of things so im going to go there with my dad since he has a jeep and were going to go mess around. at least its legal there...

 

[Gazza2005au]
