Hi all, I am changing my chain and sprockets on a 2002 SR125. I have fitted the rear sprocket to the wheel but I'm not sure how the retaining plate for the front sprocket fits and the haynes manual only indicates how to take it off and not fit it!!! Should the plate be flush with the sprocket? this can be done but the holes for the screws will not align. The only way i can get it to fit is to allow a gap of about 2mm between the plate and the sprocket....perhaps it is supposed to be like this but not sure. Could anyone advise as its holding me up big time!! I will try to attach photo. Thanks, Eugene.http://i1080.photobucket.com/albums/j326/usaaf14/SR125sprocketretaingplate.jpg

Thanks for that. The old russian bikes I have use castle nuts and split pin to secure them. I might try to get an old SR spindle as they used this manner to secure also. The 1982 to 92 ones or so had the castle nut and split pin. I think your right lock nuts should not be used on axles.

I figured it out...........

Hi, wished to attach a photo along with a technical query posting but don't know how to do this.....I am a member of other sites such as www.russianiron.com, www.g503.com and it is very easy to add photos when posting on these. I'm new here so I must be missing something? Thanks everyone!

Hi all, I recently purchased a 2002 SR 125 motorbike. It's my first solo bike as I have two rusian vintage bikes with sidecars a '58 Ural M62 which I have restored and a Dnepr K750 in pieces ready for assembly. My 2002 rear axle spindle is secured in place by a locknut. The earlier ones used a castle nut with split pin to secure. I aligned my rear wheel today and went to tighten up the locknut with a torque wrench. I had got a new nut as recommended in the haynes manual. There was no spring washer and I don't think there should be one. I noticed that the axle threads didn't protrude beyond the end of this locknut when fitted. It was explained to me by the guy who sold me the new locknut that it is the nylon insert in these nuts that do the 'locking' and if the threads don't come into contact with the nylon ring that it will not work as it should.............and LOCK. So, I'm concerned. I read somewhere online that a guy somewhere in New Zealand had an accident due to one of these nuts coming loose and coming off!!!!!!! So I am wondering if the rear axle in my bike is a replacement and not the correct length. Any advice would be appreciated so please share your knowledge with me? Would you take a look at the photo below and share your opinions with me. I am also looking for a 2002 SR 125 headlight. In my light there is 1) the shell casing 2) the lens 3) the outer rim. I think there is supposed to be a retention ring inside between the rim and lens, I saw it in a diagram online. Thanks all, Eugene.
