Sheared off kickstand
« on: September 03, 2013, 12:15:59 PM »
The P/O sheared off the kickstand. I haven't been able to find the bracket to weld onto the frame. Does anyone know where I could get one or if there's a stand from another bike that would work? Is there a generic kickstand that can be clamped to the frame? Any insight would be greatly appreciated

It probably is not sheared off but actually rotted away.  It is a very common problem with the 400 four, water travels to that area when the bike is on the sidestand,  lays in there and commences to eat away the frame rail from the inside out. Of the 8 400 fours I've had three were eaten away-two were repaired by cutting the section out of a spare frame and welding it in, if the tab is still there you can have a welder reinforce it, that is how I had the other fixed....Larry

I don't see any rot but the frame was repainted so maybe he cleaned off the rust and painted over. I don't have any part of the tab left. The kickstand is easy to find. The mount is what I can't find

Is the frame solid there?  Can you tap on it with a ballpeen and get a nice clear ring?  If so, maybe he just cut it off or had the damage fixed.  When it rusts there the frame is just eaten away(becomes very ugly).Larry

Hold on!!
No reason to chop up another frame to get the tubing!
Just go to your local metal supplier and buy a short piece of tubing.
That way you have brand NEW tubing and you can even get a piece that is slightly thicker inside.
Like .095 instead of .063 thickness. With tube the OD will be the same.

There are a number of side stand tabs available through the after market chopper/custom scene as well as other makes (ie: Triumph) that could probably be modified to work for your application if you aren't going for a 100% restoration.  Here are a couple of links to a few examples.  I've also seen some on Ebay.

Great, thanks for the links. The bike is already heavily modded so originality isn't an issue

Do not buy that Factory Metal Works,  Lowbrow Customs, or Brit Cycle kickstand (SAME PART) tab/mount.
It has the spring pin on the wrong side and the thickness of the plate of the tab and kickstand has to match.
Good luck trying to find all that, and then there is the spring problem.
You need to buy a kick stand that has the mount tab and lever with spring otherwise you will have fitment problems.

That mount tab was a Triumph or BSA part left over and they were originally attached to a much thicker frame than the CB750 is.

Buy a kickstand SET that has all 3 parts or you will find out the hard way.

Also the CB750 frame is only 1/16 thickness and all of that welding degradation and stress will be focused on that very short section of the frame.
The kickstand on the CB750 needs a doubler plate (section of tubing) at least 3 times the length of the kickstand tab.
The doubler plate should not be welded the full length. It should just have skip welds on each side, but DO NOT weld transverse across the ends of the doubler plate.

Use a welders skill to find the rot. Take a pointed slag hammer and lightly tap the frame along the bottom. If the hammer dents the frame or goes through, you will have your answer. The bottom of propane tanks are checked the same way before hydro testing.

Don't be a wrench monkey -be smart.
I was plannin on welding on a sleeve for strength anyway.
Why would it matter what side the spring is on if I get a kickstand to match?

You could have the spring on top that is true.
Getting a kick stand that has the correct thickness slot is not easy because most
vendors do not list that information.
Many kickstands sold are sold as a set with kickstand ,weld on mount, and the spring.
So if you cannot find the correct length of kick stand with the matching fit, and  a correct length of spring you will have spent the money on the Triumph kickstand weld on tab needlessly.

Then you think ... I will just grind down the thickness of the parts or cut the kickstand clevis groove to fit the Triumph kick stand weld on tab. Or I will remove the kick stand spring mount pin and move it to where I want it. Well the tab is so thick and the pin is so small that a 110V wire feed is not up to the job. It would really need to be TIG welded. Oh, you have a 220V wire feed welder. The weld on that little pin will be difficult if you apply enough heat to penetrate the thick metal tab, without obliterating that little pin.
That is not as easy as you think.

I have already gone through all of this when I bought one of the Triumph kick stand tabs. Big mistake.

Factory Metal Works (A good Company) sells the weld on Triumph kickstand tab for $27.95.... Low Brow Customs $34.95....

But you can buy a 1 inch bolt on Triumph kickstand complete with kickstand ,spring, and CLAMP on mount for $39.95 on Ebay http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR0.TRC0&_nkw=Weld-On+Triumph+Kick+Stand+Tab&_sacat=0&_from=R40

You will need to slide the kickstand onto the tube before welding the tube into the damaged frame Since it just has a one piece clamp.
OR you could use a doubler plate and buy the 1-1/8 clamp on Triumph kickstand kit but you must slide on the kickstand mount BEFORE welding the tube of the frame.
Same price $39.95

I do not know what the length of the Triumph kickstand is.

Here, before going off the deep end over this "do not buy from" statement: call Lowbrow and talk to someone there.  At least four knowledgeable people will be near the phone to help you out.  I'm pretty familiar with them since they are located about 4 miles from my house and they are at every 'event' in the area.

The British Cycle Supply  has the same mount tab listed (no price but they DO list the part numbers for the matching spring, bolt, and matching kickstand for that mount tab.
It does not say if it is a left or right hand mount. I would assume left hand but...

This is the description from their website.

To be welded to the frame tube to replace broken or damaged stock lug. Use with bolt 82-7021, nut 14-0703, spring 82-8382,
sidestand 83-1560. Comes with various diameters for different size frame tubes.

83-0035   Weld-on Mounting Lug, 7/8"
83-0035/C Weld-on Mounting Lug, 1-1/4"
83-0035/D Weld-on Mounting Lug, 1"

The Honda CB750 frame tube is 1 inch.

Thanks for the heads up about their other choices.

That link is dead. Is this the one you're talking about? http://item.mobileweb.ebay.com/viewitem?sbk=1&nav=SEARCH&itemId=111142323667

That seems like the easiest way to go if it will work.

Is the frame rail OD definitely 1"? I don't have a caliper to measure
