What effect can I expect by raising the oil level? Lowering the oil level?
That's what I'm hoping for. The forks WILL bottom under hard braking with the springs I want to run and the suspension is too harsh using any of the recommended spring rates from the online calculators. It's easy enough to increment oil level increases and test the results with the cable tie around the fork method.Air in the forks gets compressed by an upstroke. More oil and less air will effectively increase the spring rate, especially when deep in the stroke.
I figure spring rate comes first, then sag. I'm only using about half the available fork travel with the 1.0 springs in there now. This is clearly wrong, although it feels very good on smooth roads.
Very true, very true. To the horror of some, I prefer to do some things by trial and error.Like anything else to do with motorcycle suspension, the trick is to find the right balance among competing and often contradictory priorities.
I rode my Strom's suspension stock for the first (roughly) 80,000 miles. Then I upgraded both the rear and the front. While there are things I don't like about my new setup, there is enough of an improvement in many areas to make the effort worthwhile for me. There are some here that say you *HAVE* to upgrade the suspension, and I would say no it isn't mandatory, but there are benefits of doing so.I am truely impressed with all the fuxxoring around with suspension you guys endure on a street bike. Apparently my tastes are not as sophisticated as I run mine stock. I am thrilled with the suspension. I have reworked several dirt bikes...but suspension is more critical in the woods.
Now, I also ride a Road King so suspension quality of the strom really impresses me when compared to my Milwaukee mini-bike.
Nothing wrong with that, especially if it's backed up with a little understanding of the physics of the system.Very true, very true. To the horror of some, I prefer to do some things by trial and error.
That doesn't correlate with my experience. Especially when it comes to sensations of harshness or stiffness, that seems to be driven more by high speed compression damping or a spring so soft that it bottoms all the time. There are bikes like the Ninja 650 that have insanely stiff springs (in that case a progressive one that goes from 1.2 to 1.6kg/mm) and if you go on that forum you don't hear much about a stiff rideAnd I may by wrong about this, but after trying so many springs, the spring rate seems to be the biggest variable.
I think you'll be fine on that score as long as you don't go above 100mm.The ONLY thing I didn't like about the .9 spring was the bottoming on a panic stop. To me, based on what you and Pat have said, it sounds like an increase in oil level may be able to increase the effective spring rate for that last bit of suspension travel, prevent bottoming, and thus fix the part I don't like about the .9 spring.
Of course, I may also blow fork oil all over the bike too. It wouldn't be the first time a seal has let go on me.
Ricor makes some suspension products that will tame the ride of your Milwaukee mini-bike. Many of use use the Ricor Intiminator damping valves in our 650s and like the action a lot. I haven't heard results of the shocks.Now, I also ride a Road King so suspension quality of the strom really impresses me when compared to my Milwaukee mini-bike.
