    I was the one, love it but have not been able to ride much as of late as I'm currently sitting in DC with the guard... Maybe next weekend...

    I'd actually need to ask dwight that... I'm curious too so that when it needs another top end i can find that stuff as well.... All i know is it's 242cc and while but mx 250 two stroke still it has some good punch.

    I pulled my shift out today, not the failure I was expecting IMG_7372.jpg

    Maybe @andrewgore has a pic of his. I kinda recall the tab behind your thumb tearing where it hits the stopper post but I donr think Ive seen one even in a photo besides Andrew's. I might be remembering my Derbi from about a year back as it had a bad shifter assembly too, and had broken the stopper stud from the cases as well.

    It was two fold. That tab snapped and the pivot hole for the pawl wallowed out. :thumb

    A bit of straightening, a little weld, maybe a add bit of a brace. Id not try to make it too strong as the next weakest link might be much harder to repair. Did the ear out of sight also get tweaked?

    Looks like it was caused by downward force on the shift lever?

    Hard to tell, if the stop ear is bent, it may only be a little bit.

    Good eye, I’ll have to get the magnifying glass out and get a better look, my 58 year old eyes aren’t what they used to be

    If you do go to weld that small tab back on, make sure you keep the tiny spring there free of heat, otherwise you'll find yourself bending up a new one. AMHIK :fpalm :lol3

    Thanks for the heads up, I’m going to bring it with me to the shop next week, we have a huge fabrication shop where we fabricate some really big and complex industrial machinery, we’ve got a couple guys that can tig weld like Michelangelo, I’ll have one of them look at it and see what they can do.

    I'm not an expert about that period in history, though I'm pretty sure that Michelangelo couldn't TIG weld for shit! :hide

    we received some spare exhaust curves from 2021.5 in Brazil. We found that after little use, the curve looks strange. is anyone going through this? IMG_20210125_233714.jpg

    The color change? I believe mine with gen 1 and 2 pipes got burnished as well.

    It changed color in the first track taken ... The stain does not come out even with cleaning products.

    Its normal, the heat is burnishing the metal. These aren't nickel plated like a PC or FMF. Its will keep changing the longer you ride it.

    The alternative is more $ for a true plated pipe (which can still stain, blue or rust) or a painted mild steel that will rust where the paint chips off. I think these have a stainless steel blend, at least the early ones seemed to.

    And you have it well jetted Im assuming too?

    There was always a certain satisfaction to breaking out the barbecue black rattle can and making a mild steel pipe look new again. But the FMF and PC shiny pipes sure are shiny.
