I should have known this would happen. Haven't been riding my 87 Warrior very much lately so I listed it for sale. Well I have had it in my dad's shop for about 3 months and it hasn't been ridden. So I came home and put the battery on the charger overnight and got it out today to make sure it was ready to sell. Well guess what? The stupid thing isn't running right. It started fine when I choked it. I let it sit and run for about 5 minutes with the choke on. Then I rode it for a minute with the choke on. everything was fine. Take the choke off and it starts back firing and running a little rough. Then if you let off the gas to stop it just dies. FYI I have a unifoam air filter kit (no lid), a bigger jet in the carb, and a white brother pipe. Any suggestions?

 

I know that sometimes if a 4-stroke quad sits for too long, the jets can get clogged... does it feel like its running lean?

 

you're prolly running lean and the jets are clogged causing it to run lean... Time to clean the carb.
