Title: RD400 Daytona Crankshaft
Post by: racerboy9 on August 09, 2024, 03:05:02 PM
I am about to re-seal my Daytona motor with ~5000 original miles.  Would it be smart to use an earlier crank given the problems with the Daytona crank?  The bike is for pleasure cruising but I do like to wind it up once in a while.

I wouldn't worry about it at all but check the rod small end deflection, (p) in the service manual, to make sure the lower rod bearings are still within spec.  :twocents:

yeah me either unless you plan on heavy porting and lots of hp, should be ok.  :twocents:

Thanks for the replies.  I will double check and reuse my 2VO crank.
