03 Suzuki 80, idle issues

Post by trashh8r » Thu Oct 14, 2010 8:21 am

2003 Suzuki QuadSport 80
Starts and runs fine - ON CHOKE ONLY! :x
When I take the choke off, it will run under throttle, but dies at idle.
I have heard this is a common problem....anyone know what it is??
thanks for your help....TrashH8R

I had an Issue with my sons 2004 Yamaha Raptor 80.

I dont know if your mechanical skills are good so I am going to just tell you what i had to do. Take apart the Carb and clean it out really good. Most likely your Idle jet is clogged by a very smal piece of sand.

My guess would be what falcon is saying.
That's kind of my fix for most any 2-stroke starting / idle /runnin issue.

With the Choke on it actually opens the main jet just enough to give it fuel to fast idle. This is to help the engine warm up to normal operating temp. Have you done any upgrades to the engine at all?
When I put a K&N filter in my sons quad I had to bump up the jets a little to help handle the extra air flow. Where are you located? I may be able to help you.

thanks guys. =D>
Took out idle jet and it was clogged. Did I mention B12 Chemtool spray is the best thing ever for cleaning jets out!
Runs great now, ready to ride. :D

Make sure you drain the carb before storage more than 1 month OR start it every month. This saves many problems.

I am glad it helped. The problem with the small bikes is the very small carbs, lol. Yes it is a good Idea to drain the carb or run it every month or so to keep it clean. Also if you upgrade anything on the motor you will need to play with jet sizes. Many websites out there help you with that.

See you in the desert!!
