......., you don't see many people stoppedby the side of the road adjusting their susp. because a set of goodcorners is coming up! .......I guess that's exactly what the modern electronic suspension systems do??
Yes - off corse it is, and I guess it must be great for those who like that sort of thing, but we're only talking basic and Getting to know what's what.....
.Waxi,Might be overthinking it a bit - while Spring rates ona pair ofShocks might not be exactly matched they'll be close and witha twin shock bike the pre load is a stepped adjustment - put each On the same step and your Golden. Screw thread Pre-load is More the norm on Monoshock bikes.Maurie.
Does not compute: How do you convert weight (pounds) to spring rate (pounds per inch)?PS: Many shock/spring assemblies, particularly those with stepped preload adjusters, have some preload at the lowest preload setting.
Already printed And the "if it does this then the problem is probably that" section is very good.I just need to read it a bunch more times and match the changes to the adjustments I have on the bike.Better now than trying to work it out on the side of a Welsh roadMr Hagan keeps his Guzzi workshop manual on his iPhone which seems a great idea to me, cos when you're broken down on the side of the road that's when it's really useful.I've put that suspension pdf on my phone just so I can figure it out as I go.
Oh look ................ Is that a can of worms over there!: ) Maurie. A
No, just a half eaten can of b.s. I always dreamed of a bike that would perform better than I can ride. Then I realized I have 5 in my garage. Riding a bike to it's limits is beyond most peoples ability. Even professional riders.
So Waxi, yes count threads or measure length of exposed threads.
I'm trying to set preload using static/rider sag as a percent of travel.
What is the suspension travel on a 2016 V7II Stone?The Owners Manual says 137mm Front & 85mm RearThe web site says 130mm Front and 111mm RearI wonder if the V7II manual was not updated from V7 spec?I'm trying to set preload using static/rider sag as a percent of travel.
Why? What magic percentage figure are you planning to pluck out of the sky?Instead, follow what RANDM (Maurie) says on the first page of this discussion:"The Pre-Load sets the suspension at the ideal height for Damping to be most effective."There's your clue for deciding on the amount of preload to apply.
I'm looking for a starting point. Suggested preload for touring is about 30% of full travel. There is a lot of difference between 85mm and 111mm.Dan

isn't the rule of thumb 3/4 in sag?
RIGHT!!I've been reading and doing my homework and think I've distilled it down into language I can get my head around but could do with a bit of clarificationOnce I've set the sag up correctly I need to take a look at the damping.If I have this correctly the damping is there to control the rate at which the spring compresses or expands such that the wheel remains in contact with the ground and a "good" ride is achieved.NOW - when I load the kitchen sink et-al on the bike in the Summer for the Wales mission the need to reset the spring pre-load to carry the load is clear, but do the damping rates need to change?Secondly - my B11 has a mono shock buried in the middle of the bike connect via a linkage of some ratio to the swing arm.Presumably the fact that the spring doesn't travel the same distance as the wheel is irrelevant and I still measure the vertical travel of the wheel?I'm pretty good at mechanical usually, but suspension theory has always tended to fall into a bit of a black hole in the past - but this thread has helped a lotSo thanks for your patience and advice
Now I wouldn't have had the guts to post this before, but given the supportive comments I've had I'll give it a go, but anyone please shoot me down if needed. When you load your stuff on the bike Tris, remember that adjusting the pre load, (according to the combined weight of wisdom/opinion), will NOT enable the rear suspension to carry the load better, it'll just raise the rear end to give more "ride height", so when you plop the combined tonnage of you and gear on board, the bike will sit more or less level as previous. (I think !!)
