Edited Date/Time:
In the final stages of restoring my 97 YZ125. The slide in the carb is pretty worn to the point the majority of the chrome is flaked off the sides. The part is NLA from Yamaha, dosen’t cross reference with any other brands and Carb Parts Warehouse and Sudco said I’m SOL, so it looks like it’s time for a replacement. (For reference it’s a Mikuni TMXx 36)
From what I’ve gather the Keihin PWK Air Stryker is the way to go, I’m at a cross roads though as not sure if I should stick with a 36mm or upgrade to a 38. Bike will be ridden/raced vintage moto 3-5 times per year. The majority of the 38mm I’m finding come with a #7 slide which will be way to lean for the little 125. Replacement slides can be had but for around 60-70 bucks. My other option is a 39mm from a mid 00’s KTM which is also a PWK Carb (Non a/s) 5.5 slide, and plenty to be found for around 100 bones. Also have a bunch of extra Keihin jets in the garage so that would make it much easier.
I’m all ears for suggestions or thoughts.
