General Two Stroke Talk / A few questions regarding YZ125
« on: June 02, 2019, 08:54:21 AM »
I've been looking for a late model YZ125 to build a woods bike. They're lighter, and have a shorter wheelbase than any other full size bikes, handle well, and parts are plentiful.
In my research, and looking at ads I see a lot of 1-3 year old bikes with not many hours, but new cranks, new barrels, or complete rebuilds. We're talking bikes raced at the local junior/novice level. On another forum there's a YZ section, and a guy who does a lot of work on them who says at 60 hrs it's time for a complete tear down and rebuild. Other guys replacing or replating barrels at less than 100 hours.
My (CR150) Husky has over 100 racing hours, is on only the second piston, and on the big bore 165's, guys are getting 200 hours on a top end only and I've seen Husky 2 strokes with 400-500 hrs on them with not much work.
Are these YZ's really that lightly built, or are people doing a lot of unnecessary work?
I'm not that concerned (personally) because I set my woods bikes up for strong low end power and rarely wring them out
I do remember asking the Husky dealer when I bought mine about replacing top ends with regularity and he said no, It's not a Japanese bike
