Main stand spring.
« on: January 14, 2025, 10:49:09 AM »
We’ve all probably developed our own methods of fitting these main stand springs but this was the most effortless way yet for me. All you need is a a clamp and a bit of wire.

As long as nothing slides off or breaks, sending shrapnel across the shed at >800m/sec initial velocity (speed of a 7.62 bullet...)  ;)
Dunno how tough those springs are (the ones on my daily Honda's are double, hence a real PITA to work at...)

I used one of those T shaped spring pullers, trouble was I'm old and feeble in my upper body stregth, it took a few determined pulls to get it extended enough to engage with the frame bracket.

No I'm not going to start training using a Charles Atlas Bullworker.
I love the reproduced old Magazine Adverts shown later in the video.

I bend the spring just enough to create a gap between two coils of the spring wide enough to insert a 20mm washer. If you carry on doing this inserting washers along both sides of the spring you should get about 20-30 washers in there. This should increase the length of the spring enough to hook both ends over the retaining lugs or if it doesn't it should only require a minor pull on the 'T' bar spring puller to hook it over.
Once the spring is in place use a pair of pliers to pull the washers out :)

If you've had the frame painted etc just fit the stand first, you can raise it high enough with no swinging arm in place to allow the spring to just fall on, no effort needed.

Never thought of that Ken, nice one. I already fitted the swing arm and shocks but maybe next time.

Looks like Honda have finally made it easier to remove/refit centre stand springs and addressed the problem of the pivot tube seizing in the stand - it's only taken them 80 years of R&D!
The centre stand on my 18 month old, 8000 mile Forza had a few chips and scratches, so time for some TLC. The pivot tube now has a plate welded to one end with the spring post attached.  This plate is now bolted to the attachment point - the engine on the Forza.   

[ Guests cannot view attachments ]

There is a lug - not easily seen on the pic, which you can grip and rotate before inserting the bolt to hold it.  This means that there is no way that the tube can rotate, so the stand must always revolve on the tube.  Still needs lubricating though - mine was bone dry!  I still added the customary few washers to the spring though to make it easier - no more flying springs!

There hasn’t been much lube on that when it was assembled Ian, just enough to put it together probably. It was a big problem with the C90’s and other similar models when the pin seized in the stand the result being an oval mounting hole in either side of your frame. I have modified to some degree to stop the pin rotating in the frame and of course keeping the pin lubed too.
I have a 90 that’s done 8000mls too but it’s 45 year old!😂😂
