2021 VR1 850 Jackshaft Bearing

[Rbell14]

What kind of mileage are you all seeing on the jackshaft bearing. I'm at 6400 miles and will replace and likely pushing the limits. Is this exception or are you guys seeing this kind of mileage on jackshaft bearing?

Are you talking, bearing dehind the driven clutch?
Grease Zerk?
I've always greased that bearing on my sleds and helped my riding friends with their preseason maintanance and always greased that bearing and never had one go bad.
My 2 sleds are 2002's 700xcsp , still the sleds i ride. I've rebuilt both motors, still rockin strong. i have over 14,000 miles on my main sled.

The track driving shaft, (speedo cable onnection) However , replaced a lot of those in the earlier years.
I Learned that you have to pump more grease into it, make sure its coming through up inside the tunnel & spin the track by hand.

You have new sled , speedo might be all electronic, i don't know. Just Grease those bearing well !
