so i installed new fork seal on my 2010 1800. i put 15 wt oil in it, had the tubes fully extended and filled them up to 5" from the top. put the springs back in and i think bled the anti dive vale. no air coming from the bleeder valve on top on the valve. loosend the four screws holding the valve on the forks. still ride very hard. did i put too much oil in or is it that sensitive to the different weight oil. ????? not a happy passanger for the last 700 miles this weekend.

Sweet baby jeebus, that's gonna be stiff...

The fill spec for the OEM forks should be 5" (128mm) from the top of the COLLAPSED fork tube without the spring installed... all-total, you'd end up using about a quart of fork oil in dry forks.

Given that Honda says that we've got 140mm of travel, filling with the forks extended would leave you filled about 5.5" too high (meaning that you should prolly pull at least a half-inch outa the tube before collapsing it, or you'll spill!)

i had this crazy notion that it full extended, i should have doubled checked it before i re assembled it. i figured i had too much oil in it but i didn't know how much, thanks, time to drain some off.

If it's easier to work on full extended, you could drain to a level 10.5" below the top of the tube (extended) -- BUT that'd rely heavily on the published 140mm stroke bein accurate.

It may help otherslater on if you actually fill to the 5" spec (COLLAPSED) then fully extend the forks and measure the extended fill height. This would allow those that follow a quick-check method for fork oil changes that could be done on the bike.
