Hey thumpertalk users.... im in a bit of a pickle here.... im a 15 year old who recently acquired a 2001 yz426f. now this bike is a real pain in my ass. I was buying it as an extra bike as i already have a 2001 kx250 as my main bike the 426 was going to be a bit of an extra bike that my dad or i could ride if we felt like it on occasion but me being a fool bought the bike for $1150. when it didnt run right. With my 2 stroke mind i thought oh easy fix ill tune it up and go throw some rooster tails with it. WRONG. I got the bike and the way it was running it was super hard to start and is has a hot start cam/ auto decompression cam in it and it would start when i gave it a ton of gas and it ran really crappy til about quarter throttle then it ran great it did wheelies and whatnot no problem. So i decided to do a valve job and apparently did it wrong cuz i started it and it knocked literally like a woodpecker on a tree. it was the worst sound i have heard come from a dirtbike. SO i took it to a shop and got a valve job and a carb clean with the idea that the valve job would fix the knock (or so they told me) they did all that and it still knocked REALLY bad but it ran good. They did another diagnostic and are now telling me that i need a new top and bottom end and a connecting rod as well as a replated cylinder. Keep in mind i have not actually yet scene the damage and i kinda think theyre totally bullshitting me but you guys tell me what you think. Now so far ive invested $1628 into this piece of absolute crap. i REALLY would like to keep this under $2000 and im considering all options (btw if any of you would like to buy the bike i would love to get rid of it im in Los Angeles). Anyways could you guys tell me what u think the best option here is because its really stressing me out because its actually my money and its alot of money for a 15 year old to spend.... all advice is appreciated thanks guys!
