Back in August I was riding my SR-125 and when all of a sudden my engined died without warning. It was taken away to the bike shop and they identified the problem: one of the valves has become unseated and has lodged itself out of the engine! They recommended scrapping the engine and buying a second hand one, they estimate this will cost approx. £300 for the engine and installation, the bike is worth roughlt £500-£600. Would it be more economical to break the bike down and sell it as spares or do as the garage suggested and source a second hand engine and fit that?

How much is the bike worth (either in parts or in the current, non running condition) How much time and effort will it take to sell the bike in parts?
Compare the value of the bike now, with the value after the motor is replaced. Can you get more for the bike (or parts) than you would get net (after the cost of repairs) selling the repaired bike? If so then sell the bike or parts. If not, repair the bike and sell it in running condition!

Yamaha Sr 125 For Sale

It depends if it is just about economy or not and how much the bike is worth to you personally. If the bike is going to be broken for spares without an engine then you will be lucky to realise that much in spare sales. It is not exactly the kind of bike that people are crying out to repair.
If I were you I would source the engine and have a stab at fitting it yourself. It is not difficult if you are a bit practical or have a mate to help. Look at how the old one needs to come out, mark all the connections on the wiring loom, take digital photos and then reverse the process.

Guess this is the Brazilian made custom model with the chrome headlamp, it has done 14 - 15,000 miles and was getting gradually louder at the top end before it stopped?
The valve stems on this model are pap and wear right down to the valve collets in 15,000 miles or so.
Buy a second hand, made in Japan cylinder head from the earlier SR125E, buy a 1st oversize piston, get a rebore and buy a gasket set.
2 hours work and £150 will get you going again.
Rebuilt loads of these motors.

Get the spanners out! Its worth whipping the top end off and checking the damage. You might just need a new head if you're lucky. It's a common enough bike, I reckon you'd get loads of parts pretty cheap from breakers, ebay etc. It's not that tricky a job if you get yourself a decent manual. What have you got to lose?

The SR can be a pain like this. I'm assuming you have got petrol in the tank, so the most likely cause is a blockage in the carburetor air supply OR there is water in the carb. This is not common but have seen it happen if the bike been out in heavy weather. If you know what your doing, strip the carburetor down and clean it out, should be fine, alternatively a garage can do this for you, its a short job

I agree with Tinkicker, replace and repair the cylinder head, you probably won't even need to regrind the valve seats. Have a look in Motorcycle News for a breaker and see if you've got one close.
And you can always sell 125cc motorcycles, plenty of people want to get on two wheels as learners and there's always a demand.

If you know anyone who can help you, strip the engine, buy the bits you need (used, if possible) and rebuild it yourself.
Loads cheaper and you learn a bit how it works and how to look after it.
if you can't do that compare the costs of rebuilding with replacing and factor in how much you like the bike, then decide.
