NSR 125

[aLcOcK]

hi, I have just got a used engine off ebay as mine has broken. I just called up the garage for a few quotes.
he said for new piston and rings im looking at £50 to buy them then £50 for labour so £100 for piston and rings
then £18 for gasket
then £100 labour to remove and fit engine but he said im looking at £250 at the end of it for new piston and rings, gastet and for the engine to be removed and fitted.

Does this sound about right ?

is it easy to remove an engine from an nsr and re-fit it as this would knock off £100+

thanks

Have you tried using David Silver Spares/Wemoto to see how much the parts are? Pay for the parts yourself then look to get the mechanic to fit them/rebuild... my mechanic was going to charge me £90 labour alone for a top end rebuild...

Hi

Removing the engine isn't difficult, but depends on how much experience you have.

Just watch out for the easily forgotten things that you suddenly find while trying to hold the engine in your hands. Like the oil pipe to the oil reserviour.

All the best

Hi

Not sure of a guide. Generically.

Remove anything cosmetic (petrol tank, fairings, etc) and put it somewhere safe.
Unbolt the exhaust and take it off.
Unbolt the airbox, take it off and then take the carb off.
Disconnect the oil line to the oil tank. Make sure either you empty the tank first, have something to put the hose into for it to empty of you have something to block the line with.
Disconnect any electrical connections (temp sensor, ignition, neutral switch wiring).
Remove the chain.
Remove the gear change lever / linkage.
Drain the coolant (might help to remove the radiator as well, depends on the bike)
Slacken off the engine mounting bolts.
Support the engine, remove the mounting bolts and lower the engine. With a 125 engine a helper can probably support the engine for you. With a large engine you might want to play around with an engine hoist.

Reassembly is pretty much the reverse of that. But make sure you check the engine oil, bleed the 2 stroke oil system and double check everything is done up properly.

All the best
