It's your baby, but my advice would be part it out and get your money back, before you live to reget it. It's going to take serious coin to have it back to decent condition and you will be left with one of the slowest 125's ever made.....Just sayin'

...so I have to be competitive with 450f's.

I am not bashing your bike, as I love a good project. But this quote and that bike do not fit. Sorry dude but unless the guys on the 450's are complete noobs that just started riding that week, you bought the wrong bike for that quest.

Good luck with your project and I'd love to see pics as you progress. I had a 1988 YZ125 back in the day and used to have the repair manual but I gave it away a couple years ago or I would send it to you.

Well I'm a firm believer in that its not what you ride its how you ride it so I'll be going into training myself and then the bike just needs good topend power an suspension that can make the most of its weight advantage, there aren't so many tracks round me where a 450 can get to full pelt so a well ridden 125 is usually fairly competitive.

Well I said what I said mainly because the late 80's early 90's YZ125's are legendary in their lack of engine. The one I had, even after a rebuild, was a dog. I didn't race MX with mine though. It did ok on tight trails. But if the trail opened up the bike really struggled on top.

I am in no way trying to discourage you. I think it's great you are excited about this. I just hope you realize that a 1989/1990 125 is not in the same league as a newer model 125. But have fun as that's all that matters  ;D . I am serious when I say I am looking forward to watching your progress.

If you where racing in '91 then you might do it for sentimental reasons

 you could easy throw 1500 quid at it and still be out gunned by an 85.


Haha I wasn't even born in 1991 and I often get blown off by kids on their sx85s anyway even when I had the cr250 so its all good.

Anyway I've been looking into the mods that ight help me turn this thing into something a little more competitive so my thoughts so far are to fit the Link Atom injecting into the transfer ports this should get rid of the problems that the carb and reeds were crap and then a TZ250 piston and some porting shall be done aswell as a new pipe (not sure whats best yet but apparently the stock one was crap) and oversized radiators. Any other mods anyone thinks would be good please let me know.

Obviously this will be expensive so don't expect it to be all done an dusted by next weekend.

That headstay has alarm bells going off, I haven't seen that on a 125 before :o
have you checked the frame for cracking..or more like breakage than a crack. Might have something to do with the engine swap though.
