Used parts are taking up way too much space. Some parts in really good shape & others not so much.
Have complete gauge cluster for GT550, GT500 (T500 parts bike had GT500 cluster) & probably GT250.
GT550 exhaust gone. GT250 body set sold.

Ask if you are looking for some parts we didn’t use in the builds.

Here are two T500/GT500 battery boxes:

GT250 gauges. They worked fine prior to the cafe build.

GT250 front brake was rebuilt some years ago: master cylinder + caliper + stainless steel brake line

I'd be interested in a battery box, particularly if you have something else from my list to make the shipping viable? Its T500 not GT I'm after.

Battery Box
Side stand and frame bracket
Engine attachment bolts (all three)
Front axel and dust cover
LH side cover
Chain guard
Later style fuel tank
Nut / Ring for attaching the ignition switch
Fork springs
Handle bars
Throttle assembly
Handle bar switch
Clutch basket

Cheers

Will look to see what parts I have.

When I bought the T500 project bike, it already had a GT500 triple tree & forks. So I don’t have T500 fork springs.

I have a 69 T350 that needed new fork springs. It has external springs similar to the T500’s.
I found modern springs that work. They might work for your T500, depending on your needs.

Hi Jabcb,

Cheers, I'll take a look at those springs. Might be helpful in that when I did my original T500 I bought some 'new' fork tubes, but when they arrived they were 4" longer than stock. So I ended up getting an OEM set hard chromed and ground to restore them which went on the Mk111.

I'm going to use the tube I have. But 4" is way to long so they are going to have to be shortened. But, I am thinking to keep some of that extra length with a longer shock to alter the stance to a bit more scrambler / super-motard. So that would require finding a spring that long enough to suit.

Let me know if you find anything else that would make the shipping to the UK worthwhile if you OK with sending overseas.

Cheers

I did a lot of research before selecting that spring.
The T & GT series forks do not have top-out springs. Per the CycleWorld article, the bigger Suzukis would benefit from more spring preload & softer springs.
(Modern forks have top-out springs & the preference changed to less preload & stiffer springs.)

The T350 & T500 have 7 inch springs. I used a shorter length in the spring calculator because the T500 has a few spring windings that are inactive.
I investigated all of the modern springs in stock sizes that fit the T350 that I found. The one I selected was the best option.

Whatever length you add to the stock inner fork tube length is also added to the length of the spring. If you don’t add the length to the spring, then you need a spacer.
This is because the spring rests against the lower triple tree.
So if for example, you add an inch to the inner fork tube length, you add an inch to the spring length. This may give you better options.

The biggest problem I found with the external springs is that they have to be short. As a result the spring stresses are rather high & the springs wear out and sag much sooner than internal springs. So keep spring stresses in mind when you select a new spring.

Switching to an 18 inch front rim will offset some of the extra for tube assembly length. So that is worth thinking about too.
I’m using GS-series fork tube assembles on my T500 cafe build. I’m taking advantage of that because the GS assemblies are longer.

Yes might thoughts exactly won't have any more travel but more spring length wold allow more coils to soften the rate. May be even two springs to give a dual rate more progressive rate through the travel.

Long way off making that decision need to get it mocked up first once a get the wheels rebuilt.

Two springs with a short soft spring might allow you to emulate modern spring designs. But the math to get it right might be tricky.
Likely to be interesting if you come up with something.
Just make sure the soft spring is not overstressed at solid height.
