Most likely if you do the changes and go to a 6HS plug and drain fuel bowl completly .
If that doesnt work it may be a ground issue or stator.
Good Luck eh!

 

Hi there--New Guy to the site...........My daughters Arctic Cat 90cc did the same thing. Simple fix!!! Unscrew the end cap on the exhaust and pull out the Baffle material that has loosened up. If its not there, drive the atv for a while and the loose crap should come flying out.

You probably have a stopped up pilot circuit/jet and could stand to go a size larger.

 

fastnature,
Is this machine stock?
Plugged up exhaust...caused by Using Wrong injector oil.
Variator roller turned sideways.
Carb needs cleaning including all jet passages. varnish build up. Water/trash in float bowl.
Seizure or wore out bore.
Transmission bearing failure.
Chain adjustment to tight.
All of the above.

 

ok my little brother has a 2001 scrambler 90 that has all the same problems. i think it may be the rings possibly building up back pressure and forcing gas into the air box but would like some suggestions before proceeding with a complete overhaul. it also will not start with the electric start. i touched a hot wire to the starter and it began turning over but does nothing with the button. please help

 

its a safety feature to shut the quad down in the event of a stuck throttle it has adjustments in the owners manual.Maintance Section.I just bought a used 01 scrambler 90 that i had to clean the carb in and the starter drive gear is bad "teeth missing" I have been kicking this thing all day i come in to do some research and downloaded the 2002 manual from polaris "was none for 01" it was the youth owners manual and i seen 2 safety switches one the teather duh, and then the electric throttle control wich is in the throttle trigger and the carb go figure I will try it tomarrow hope it works for my machine

 

i have a 01 scrambler 90 same problem i have changed all jetting numerous times nothing changes it ambient temp seems to have no effect on this thing i have tuned several engines and nothing has been as hard as this thing any help would be apperciated

 

i know this is a pretty old thread,but i think i have some long awaited good news (at least for me)saw that many others had same issue.after changing out just about every part possible,the verdict is that the circuit that controls the electric choke solenoid on the carb. and not the solenoid itself is the problem.switched to a manual choke cable setup and solved problem.i waited for 3 months of positive testing before posting this.hope this helps the hundreds that have struggled with this since 2001.kit can be purchased for $60 at lakemotorsports.com.

 

For the rear I changed the shock out to a generic pit bike shock that was sprung for adults off ebay and it really helped. They can run fast but you need to stay on top of maintenance to keep it reliable.

 

my kids 01 scrambler has always run great but the other day my son was riding it for maybe 20minutes and then it just died. I can start it up and it will idle fine but as soon as i put any pressure on the throttle it dies, every time it doesnt bog out it just dies. any ideas?
