Question 04 600 HO All Fixed Except 1 Thing (HELP)

Some of you followed my thread here of all my issues I started with: https://www.polarisatvforums.com/foru...-question.html

Now it fires up instantly and warms up and choke comes off so I can go for test drives. My speedo needle and mileage isn't working but all else is working fine i the cluster so I cleaned the Hall Sensor but no dice so I ordered a new one. My 4WD switch works fine and it goes into 4WD.

I start it up and go for a ride up my rode and it runs well up to about 30 mph and then if at any time I try to go 50% throttle it will choke up and back fire out the exhaust unless I back off or go 100% throttle and the nit kicks in and takes off well. IS this due to the speed sensor being bad or is there a spark/ignition or carb problem that makes it spit fire at 50% throttle only? WOT and part throttle is smooth, maybe another set of plugs but I doubt it?

i would say you have probably a problem with air or carburetor,a nice cleaning can't harm
