Well I'm Thomas and I'm an alcoholic...oh sorry, wrong page. I just picked up a 2017 z125 pro this weekend. Traded a 05 crf450r for it. I think I got the better deal. ? Thing only had 62 miles on it!! So far I am stoked, other than the power of course, but I will address that in time. Had a klx110 with the 143 kit on it, so I know these things can be woke up. So far, ordered a bunch of China crap to do some blinging and cheap fender eliminator, I will post links and pictures as the crap comes in. Main question I have so far because I'm being lazy and haven't tore apart my airbox, what size is the end of the stock airbox hose? Heard different things ranging from 35mm to 50mm. I just want to order my **** uni! Thanks!
