Maxxis Bighorn questions

WHat's the difference between Bighorns and Bighorn 2.0? Also as im looking on Ebay and other places I see HU9 and HU10 in part number, what would this difference be? I need to get two new rears for 2018 RZR 1000XP and not sure what to order?

THanks

new 18′ outlander 450 owner.. oil change question

is there a simpler way to change the oil (namely the filter) on this quad? according to the owner's manual its looks like a process... which I thought was kinda silly for just a oil change. also can you still get a paper back service manual for these quads? thanks!

New 2018 sportsman XP 1000 and SP 850

Hey guys I’ve been a member here for a long time under 1roadking but just had to change my username due to no memory of password and email used LOL. Anyway, I just wanted to update my rides and ask a question about my 1000, I am loving the power and it is a beast of the line compared to the 850 but I’m having a hard time getting a smooth take of and lurching at low throttle and speed. I’m not sure if I just need to get use to the throttle by wire or there is something wrong. It’s literally brand new and I rode it about 1 mile in my driveway and yard. I also just bought my son a 2018 SP 850 on Saturday and that is smooth as can be on low throttle. Any thoughts help is appreciated. I also have a 2015 XP 850 they had been great to own but traded a 2015 570 eps that had tons of charging issues!
