???? Lee, sorry to correct you but It's all the same..shock top or bottom or link, or ride height or extra preload. lifting the back end by ay of these methods raises the frame with respect to the rear spindle, lowering it drops the frame. If the frame is higher off the ground the bike leans over further on the stand..just as pointed out in his post

What can I do?
Well my ride setup is standard (I'm guessing yours isn't otherwise why would it keep falling over)

So I'll measure the distance of the bottom of my side stand to the floor when holding the bike upright.

That way you'll then be able to work out what size stand you'll need to find to make it the equivalent to standard again. If that makes sense :D

I'll measure it at work today and get back to you.

if you have put a 6mm spacer under your rear shock, you have raised your seat roughly but 26mm, angles and stuff. therefore if the rear of your bike (seat) is 26mm then the middle of your bike(frame, sidestand) will be about 15mm taller. are we still here. therefore your side stand needs to make up this difference in height to keep your bike at the same angle(longer) when on its side stand. because the sidestand pops out at an angle aswell you need to factor that in also.
I could bore your with the maths but I won't .........it needs to be 22mm longer :thumbup:

Yes it does move the bottom of the bike higher up from the ground :!:

You obviously haven't tried using a shock spacer, or if you have you've not noticed the different lean angle of the bike on it's side stand, especially with a 6mm spacer.

By fitting a shock spacer you are altering the angle of the swingarm, just the same as fitting a lowering kit, the angle at which the swingarm sits is changed. By altering the angle of the swingarm you are raising or lowering the mounting point for the side stand, it's as simple as that.

Try looking at it this way. When riding the bike over a bump the swingarm is pushed up nearer the rear subframe meaning the angle of the swingarm has changed. This in effect brings the mounting point for the side stand closer to the ground, does that make any sense :?:

Dear Dr Storm

Good lord!! So many entertaining ideas!

Well, after my last idea increased the incidents of falling over (cut the bottom off of the side stand) I have decided that too short may not be the way to go

I have now welded the bottom back on, with a 22mm extension fitted

Wow! What a difference.................it now falls over the other way

This is much better, rather than fall over onto pedestrians it falls into the path of cars and lorries :lol:

So much fun watching them swerve all over the road, better to watch than countdown

However, I now have another problem

My bike falls over the other way

What can I do

Yours

Flatout

I actually have one fitted already lol. My mistake, had it in my head that it would have to go under to lift the whole bike :confused :confused . Too many beers :beer:

With my bike being held upright with the side stand down there is a 40mm gap between the bottom of the side stand and the floor.

Hope this gives you something to go by :thumbup:

I beg to differ.
The rear of the bike sits higher than previously, by a ratio of about three to one, so a 3mm spacer gives 9mm height increase, a 6mm spacer 19mm, at the bodywork above the rear axle point.
As the stand is halfway (roughly) along the bike, that effectively shortens the stand by a few mm, and the bike leans over more than it did when parked up.
Stand is the same length, but the frame it's bolted to sits higher than it used to.
It's not falling off, it's an upgrade opportunity.

Like I said previously, my mistake, the Fosters was frying the grey matter.

Dear Dr Storm, next time you see Flatline ask him how much the extension should be so we can stop this stupid thread........................ :idea:

Flatline by name Flatline by nature. Your bike just likes a little kip now and again ZZZZZzzzzzzz with or without you on it. :roll:

For all your interested it was recently discovered that a Blackbird sidestand will fit the VTR. They can be picked up fairly cheap. :thumbup:

:lol: :lol:
