TY250D - Brake pedal/stand mount clash

[Dunny]

Hi guys,

I got this thing in a box. Between research and guess work I am tyring to get it back together. Issue is when I fit the rear brake pedal and pivot onto the collar and spring the swing arm will not line up with the pivot as the rear of the pedal hits on the side stand mount bracket.
I checked the alignment of the brake pivot collar and looking at it I can't see any cracks in the weld or paint. Should I just put a bar in the collar and bend it inwards and try a make a little room for the pedal?

Appreciate any help.

BTW, if anyone has a spare side stand for sale I would be interested.

I seem to remember that the standard setup on the D model allows the fitting of shockies of 350mm or less before the front edge of the stand mount hits something. Is that your problem?

Hi Dunny,

Photos will help your cause!

There is not a lot of clearance there, perhaps you have the arm that pulls the brake cable in the wrong position on the spline.

What is the length of your shocks between centres without load? Too long will reduce clearance.

As to putting a bar on the mount and bending, the pivot hole should be 90 degrees to the axis of the bike.

Check the stand (if you have one) supports the assembled bike without leaning over too far as this will tell you if the stand mount is bent.

Hope this helps?

Thanks for the response guys,

David, the shock length is 345mm centre to centre, BETOR gas shocks.

Greg, The cable arm looks OK and it does not hit the mount, only the rear of the brake pedal where the bolt is.

It does not look exactly 90 degrees so I might try and give it a tweak with a long bar, and keep the welder handy.

I just had a look at a few B and D model skeletons tonight and have thought of another possibility for why the stand mount might be hitting the pedal. Is it possible that the stand mount has been rewelded in the wrong spot or at the wrong angle? It is pretty common to find derelict TY250s with the stand mount broken off or re-welded back on.

[Dunny]

There looks like plenty of meat on the front end of the stand mount. I might be able to trim it off with a grinder, just enough for the pedal to clear it.
Not sure if the new shocks fitted at the max length is an issue? I saw a set on e-bay with a 320mm eye to eye measure, not gas but don't plan on riding this one much and it may help. What do you think?

[David Lahey]

Yes shorter shocks would help of course, and 320mm is about what they came with new. If it was my bike I would persevere with making clearance by grinding away the front edge of the stand mount and use the Betor shocks. The action of the Betor shocks and the steeper steering angle from using 345mm shocks will make it pleasurable to ride compared with the cheap shocks. If the 320mm shocks are the shocks I'm thinking of, they have terrible damping and a spring rate more suitable for a Mack truck than a trials bike.

[Dunny]

100% correct David. I had a good look at the stand mount and although the weld job was that good it looked original it was in the wrong position. Grinder and welder fixed the problem and all good now.
Thanks for the heads up.

Now for a side stand !!!
