Just picked up an 08 outlaw 90 for my son. The thing is spotless and the lady I bought from said her daughter only rode it for one summer and it has been sitting. I know her personally and it still has the tits on the rear tires. Got plenty of PS4 on the shelf but the manual says it takes Polaris youth oil? So is there any difference in viscosity between this and the big boy ps4? What does everyone run in theirs? Just don’t want something too thin in there. Also if anyone wants trade a mint set of pink plastics for a blue set let me know. Thing is as close to new as it gets and at the moment he doesn’t care that it is pink its I great upgrade from his 02 sporty. He’s only 5. The reverse gear is getting a work out. He tells me keeps backing up because he can! Thanks guys
