I was 16 when my build hit 3 grand lol. now im 17Yeah I already have 423 into it it's getting quit expensive for a 16 year old that's funding it
they are always a work in progress. and $423 isnt much. when it runs good you could sell it for around 800-1000 depending on the area
plus if you ride it for at least a year and then still make a profit (if you sell it) thats priceless
once you get it running, you will only want to pour money into it. hell i have run pipes that cost as much as your quad
