ok on my little brothers, he's 7, 2000 trx90, when i had it i always ramped it till about a month ago when i got my 400(yeah its sad i had a 90 and was just turned 14 ) any ways from ramping so much it now feels like you are ramping 7ft instead of 2( had to try it again). is there a way to get them back to normal or should he just get new ones
