Noob: Hi and got a couple of problems

Hi all,

Just bought a 2002 NSR 125 with a few problems. Nothing major as far as I can see, I've took it for a ride and engine performs well and just feels like an all round good solid bike.

I bought this bike expecting to work on it as I wanted a project to do for a few months, will be a change from cars!

Anyway, I have noticed one of the front forks is leaking, and also the 2 stroke oil is leaking, quite badly. I'm not an expert on bikes but looking I can't see the fork seals been hard to replace? and I think the oil is leaking from a gasket, loosing quite a bit, is this a common problem and can anyone share any tips, advise, aprt numbers etc.

Cheers
Walshie Thumbs Up

....Site seems great btw

what gasket is it leaking from?/
pics might help.
fork seals on any bike can be a pain in the arse, but not really too hard, you'll also need new fork oil,
the best thing you can do is buy a haynes manual for it

I think its the oil pump, but having another look tonight, it me be running down the pipe from the 2 stroke tank. Think I'll cut a few cm off the pipe this weekend just to see if its split round the edges.

As for the forks, from what i gather from BCF I may need a special tool, I think i might just take the forks off and take them to my local bike shop and get them to do it.

....also been told I can't get a haynes manual for a nsr 125 for some reason

Cheers Thumbs Up

Haynes manuals arent available for this bike, so was a pretty useless comment from above.

Take your forks off and take them to your local bike shop, Watch what he does and know for next time ? Will cost bugger all aslong as it isn't a dealer. Fork seals are £6-£8.

OR

Refer To Here

And regarding oil leak. If it's leaking from the oil resovoir as you say, Clean off the leaked oil and check where it leaks from. Could be a split pipe as you say - most probably. Or there may be damage to the resovoir.

Just clean off first unless it's already obvious where it's coming from ?

Haynes manual is a no no but if you go to a Honda main dealer and for approx. £25 they can order you a re-printed manual which is a lot more use then the shi* haynes produce.

I've not had any problems with mine, however for parts you want to try these:

Genuine parts : www.davidsilverspares.co.uk

Other sites: https://www.bitzforbikes.co.uk/HONDA/NSR_125/R-1_01_-_03

David silvers is probably the better one to go for as they can get all teh parts and deliver pretty quickly, give them a call and describe what you need and they'll get it.
