so you can infact use lower than the manual spec oil level?like I said not 50% less or such,and it doesent matter brand or road or dirt,show me where you must never ever use less than the spec level?most manuals say do not overfill!pretty feeble argument against never using less fork oil so far.
Dave, yes you can use very small amounts less to get the manufacturers specs or to balance both fork legs, as long as you know how much air is in the forks, you know the limits of the travel, you know how to measure sag , you are basically adept at modifying suspension, there is a very fine line between getting it right and getting it wrong, as your link clearly states, most people wouldn't have a clue as to how to do this properly, the fork oil level shouldn't be used to soften the suspension. Originally you said 20-30mm mate, that just under an inch to just over an inch and I wouldn't take that much oil out at all, the only reason i would take a small amount of oil out is to get the forks to the manufacturers specs or the specs of the suspension being used. I can't find one link online where it says this is acceptable to do on a road bike anywhere, the only information i read was all based around the manufacturers specs and making minute adjustments for racing, to make both forks perform the same, nothing for a street bike, other than to achieve the correct suspension travel, once the correct level is achieved, alterations to viscosity is the way to alter the feel..... I'm going to have to agree to disagree with you mate....
