Fork Compatibility Question

TheLastJoker
Well I finally made my first expensive mistake during the rebuild of my '78 750F.  With the intention of leaving the front fender off the finished product, I torqued the fender mount bolts down until they were flush with the mount holes (really tight).  After doing this, the stanchions would no longer compress into the lowers.  Apparently I had tightened the bolts enough to warp the lowers   My question is, will forks from a later model F fit a '78?  I'm looking at these on ebay as they appear to be identical http://www.ebay.com/itm/Honda-1980-CB750F-front-fork-forks-suspensions-dampers-h80-cb750f-002-/130872270257?pt=Other_Vehicle_Parts&hash=item1e78985db1&vxp=mtr  If anyone has any advice on this matter it would be much appreciated!

Yes those are the same forks, and will go right on.

Over-tightening of bolts is a common problem on all things mechanical.  I'd recommend a ~$20 clicker Torque Wrench (ft-lb and inch-lb. are available; ft-lb is more commonly used, but having both means you're covered) from Harbor Freight.  They claim to be within 4% of stated torque, which is so much closer than guessing...

The oil drain plug is one of the more common things to damage by over-tightening (usually requires a new oil pan and bolt...).  A Torque Wrench will allow you to get it tight, without damage.  Same applies for all other bolts on the bike.  The FSM has most torque values listed, so you will know they're tight and right.  Cheers!
