Full/partial rebuild of 450 FSE 05 motor - how often

[expirmininkas]

Hello mates,

I've read through the posts, also, checked the manual and did not find any info on how often it is necessary to change bearings inside motor, piston/rings, also, how often it is recommended to change also cylinder (with all belongings). Could you tell me if you know?

Regards,
GG 450 FSE rider

I assume that nobody knows the answer?

Run it until it blows up or stops being reliable and part it out. That's what I did and it was the best thing I could have ever done to it! Then move on to pretty much any other dirt bike ever made. Like a 2t GasGas.

Thnx
How often do you rebuild top end? How many hours/km(miles) can you do with full tank?
