    Nice, I have a 81 YZ 465 that's currently a basket-case project. Sadly it's one of those things I keep talking about and haven't started yet. I have too many things that all need fixing at once. The YZ is going to take some time, I want to do it right and it's going to be painted a similar color choice as Mike's 125. But I'm wanting to do it in more of a late 80's early 90's theme. Almost like a KX 500. :)

    Hot Rods is 50/50. Sometimes they're great and other times the rod snaps at the piston and takes out the entire engine. Had one that lasted hundreds of hours on a big bore trx450r and still running. And another that lasted 20 hours. Always weld the crank

And gave me some number of "oh the price is actually going up on that kit so we charged u what it shows online" says I still "technically got the %10" but I wanted to lyk b.c. If its supposed to help u out or your sponsorship then thats kinda b.s. 1900 a big purchase u brought them lol and now the pistons on back border i guess.

    Wiseco and hot rods are the same company now, and they have not alleviated the issues, rods on both of those cranks need pulled apart, checked for tolerances and then re trued, dealing with several of their cranks that have locked up with less than 5 hours

    If you weld that crank you’re gonna have a helluva time truing it because it’s guaranteed to get tweaked, I don’t think a YZ125 makes enough power for it to matter.
