How many bottles of fork oil to buy?
My local Honda shop says the superhawk should hold about 450cc's of oil per leg, which equates to 900cc's for both legs. This translates to about 30oz for both legs.
1 liter of fork oil is 33oz.
Using this math I should only need one bottle of fork oil to do a complete fill for both legs, (assuming dry fork legs). Do you guys agree with this, or should I order two bottles? I will be completely cleaning out the forks, drying everything out, then installing fresh oil.

jamie had suggested a oil viscosity of 15-19cSt for my forks (his valves and shim stacks)I chose one at 16.2cST@40deg, Maxima Racing fork oil 5wt.
Next time I drain, clean and refill I may try something in the higher end.
Im told 7.5wt Ohlins is 19cst@40deg

I don't know if this is a good idea or not, but I usually flush my forks with some paint thinner during an oil change to flush out any sludge, metals, etc. After dumping out the thinner I put some new fork oil in, pump the forks several times and then dump it out before final refilling. Sooo I need a little extra oil.

Yes, that is a good idea. I did something similar today.
I rinsed out with QD Contact Cleaner, also filling the cartridge with QD and pumping it out, finally airing everything out with compressed air. I rinsed at least three times...
Good input, thank you!

I fill with Silkolene pro rsf 5 wt to 150 mm air gap but I may be high there as I did not check my records and its been 2 years as it's on my winter todo list. My valving and damping is by Greg Nemish. I made my own preload spacers and run RT .90 or .85 springs (again brain fade) but I like it a little soft as it balances well with my Penske shocks spring and damping.
