Oh wise one's, please fill me with your years of knowledge. This will be my first old bike, 1976 Honda CB400F (Four), shed find, very rough, apparently runs (although no carbs with bike; PO used his 350F carbs to test). No knowledge if the gears are ok as the PO didn't spin the motor because the rear wheel is damaged.
Used to high performance dirt bikes where parts are ususally replaced at the slightest hint of use, just rebuilt my KTM 2t enduro because it sucked water into the crank case.
My philosophy with motors has been to replace when in doubt, however I am not sure how robust these things are, my previous dirt bike was a WR and at 7,000 k you would probably be looking to replace the whole valve train. I would rather not be doing un-necessary replacements if its overboard.
So...
1. Should I look at getting some carbs and running the bike prior to splitting it open?
2. What should I look at replacing in the motor when I split it apart? I am probably going to bore the pistons out to 466, does that change the answer?
Was currently thinking of replacing gaskets, crank seals, crank bearings, cam chain and slider.
Thanks in advance.
