Rear suspension seems to have changed

[Duezzer]

Hi there all

Put on a few farkles the other day and ran into something I did not expect.

I installed

Longer dog bones ( the real name for these slip my mind write now but you know what I mean ) on the rear suspension

A set of the riser blocks for the handle bars

I also raised the forks up in the triple tree to equal the reduction of the rear end

Now my rear suspension seem very spungee/soft

Is this due to the longer bones on the rear suspension creating more leaverage?

Did I do something to the shock when I changed them out?

I have swiched the bike to the HARD suspension setting to see if that would help out but made very little difference. I had been running on the soft becouse I have been running a slab for the last little while and the soft was just a wee bit nicer.

Should I be looking for a shorter shock insted of this other fix for my 30" in seam?

It also looks as if I will have to cut the side stand does anyone know how much to cut off to get a decent lean angle?

Suspension geometry is a very sensitive balance. Longer bones definitely change the leverage and would probably require a stiffer rear spring to get the same loading, rider sag etc. You can't change pieces like bones and not expect to also change to aftermarket shock without some noticeable sacrifices.

Gunny!

Anyone have a sudjestion on what spring to replace the stock spring?

What type of shock instead of the dog bone replacement?

Has anyone else who has lowered thier bike ran into this issue?

A cheaper thing would be to shim the original spring to see if that works before spending the bucks for a new one. I don't know about gen2 bikes but on the old ones the shock comes out easy and you can get a shop to do the spring work if you don't have the tools. I may still have a couple shims somewhere if you want them.

The original spacer recommendation was to keep it at a maximum of 1/4". The other two spacers were 1/8" & 3/16". Combining them *may* be too much ( but I'd try it ).The quarter inch spacer I had added to mine was barely enough for us even though my wife is petite. I now have a 1" shorter Wilbers shock with a heavy (140 kG) spring & love it.

dobias :glare:

PSon't "cut" the sidestand, just file the stop a little at a time to get the lean you want.

I'm around 29" - 30" inseam and I can almost flatfoot. Becauseof the reasons that are being discussed in this thread, I have never even thought about lowering it.

With all the ABS stuff in the road, taking off and putting on shocks may not hit the PITA level but it isn't on the same level as changing the oil. IMO, if you aren't familiar with spring changing, going to a shop is a VERY smart thing to do. Also, I'm with Jeff, playing with the dog bones is an area that engineers get the big bucks to figure out. Getting unexpected consequences is to be expected.

Thanks for that tid bit

Went to the Yammie store today and checked out how the rear end reacted in the stock form

Seemed to be pretty well the same as mine is now so I am not all that worried now

When I pull the bike apart in the fall I may do some suspension upgrades then and put in a shorter shock and get rid of the bones

One odd thing is when I sat on the bike in the show room I could almost flat foot it, my heels were just off the ground and I think if I had my riding boots on I would have been very close to if not flat footed

I don't know if this means anything but it was a electric shift model

I am not even flat footed with my bike lowered - Yes I do have the seat in the lowest position

Any one else run into this

Later.
