125-200cc Bore kit for 125

- I have a 2002 husqarna wr125 and Im curious what the stock piston size is. I believe I read it's like 53.94. So knowing that can I order just a 54 piston with new ring and drop it in?
And or what is the cheapest bore kit available?


- Also I took the carb off to clean and curious of anyone has a idea of how the vent tubes are ran.. Do they all go to the bottom of the frame? I thought 2 of the Lines on the top went into my air box but can't recall. It's a mikuni tmx carb.



Thank you

The vent lines should be routed down. I bundled mine together and ran them down through the swing-arm area.

Unless someone before ran 2 of them to the airbox. Many enduro guy's will do this for water crossings so carb will still "breathe"

I agree.
