Hi Norton
Most of the kickstart gears are 20 teeth which is I think standard 350. I have one at 19 teeth which I believe is 500 6 speed box. The 5 speed box is 23 teeth. Do you know which you have?

Hi Ian,
I’m sure it is a 5 speed box, will double check though. I have sent you a PM with my number.
Cheers,
Norton

If it is any help the kickstart gear of the 250T is the same part number (14.04.25) as the 500W (I have never heard of a 250H - I believe the 125 used that letter).

Thank you Ian, they are proving to be a rare commodity. 500 exhaust collets that is

Hi Mike
Sorry the system failed to tell me I had a new message. I will try and look tomorrow but have a lot on and am out all day Tuesday.
Thanks
Ian

Hello Ian,
Would you have a useable pair of Marzocchi stanchions for a Strada K1?. 605 long, 1.5mm pitch threads at the top nut.
Thanks,
Alan.

Hello Alan
I got 1 NOS 35mm stanchion in the stock of bits. It is 601mm long however. Machining tolerance? I know they are supposed to be 605mm. I have a feeling I found some new ones recently that were not too expensive. If I remember where I will let you know. Cheers Ian

Thanks for the reply Ian.
I have hopefully found 2 NOS ones in Germany, they should been their way soon.
Is that red K1 fuel tank still around?, if so, what nick is it in?.
Alan.

Hi Alan
That tank and most of the others have gone. Good luck with the stanchions

I can confirm this:
- 19 teeth: 500/501 6-Gear (the only one with somehow "pointed" teeth)
- 20 teeth : 350
- 23 teeth: 500 5-Gear and 250T (as far as I know, the whole gearbox is identic)
The upmost sprocket on the kichstart shaft should be carefully chosen to fit the teething (there are slighty diferences concerning the form of the junction teeth!)
The rest of the kickstart mecanism is allways the same at least in 350, 500, 501 and 250T

Primary gear:
350: 29/66
500/501: 31/63
both are 23 mm thick

In 2011 I tried to resume the main diferences between the 500/501 and 350 motors in the german forum. In the 4th post you find the results.
I don´t have the time to transduce all that right now, sorry. If the admins like to pas that informacion to an other place of the forum: go ahead!

Thank you for the response Norbert. Useful information

Cheers, Norton

Hi Ian,

Just checking, what parts for 250s do you have? Was that a slightly dented 250 / 125 that I saw in your first photo?

Look forward to hearing from you.

Regards,

David

Hello David. Yes there was a 250 tank but now gone. I have some 250 forks and yokes still for sure. What other specific bits do you need and I will have a look. Thanks Ian
