NS125R Engine

I managed to write the engine off in my pride and joy  :upset: 

Does anyone know where to get hold of a good condition replacement engine for a 1989 Honda NS125R (F or K - both fit) or how much I should be paying?

This is the whole lot from cylinder head (not valves unless I have to) down as far as the crank. The kickstart appears unaffected

If you have an engine e-mail me seanchapman@hotmail.com  :smile 

Thanks.

Is your engine that far gone that it is not rebuildable?  If not, have a word with Stan Stephens.  If its rebuilt at least you know that its a good-un.  Buy a used engine, particularly a two-stroke, and it might be in an even worse state than yours!

WOW

24 year old NSR 125RK,to find an engine for that would be a find on its own,i think as MM says it would be wiser to have it rebuilt,if its just an engine rebuild it will cost about the same as an engine if you could ever find one?.Probably be no more than £250? unless the barrel needs re-Nikasil,which could cost another £100-140? on top.Thing is there are lots of spares about for the later engine,but if yours is a genuine 1989 its the first and old engine and its very different.

Good Luck

firstly, thanks for the help.

and yes its a genuine 1989 which is that far gone. the spark was too big, blew a hole in the piston which gouged out the inside of the cylinder and tore itself off the crank denting the cylinder head as it went. i really dont think its even slightly salvageable 

i was thinking of getting a newer bike soon anyway, i guess i could do it sooner than anticipated...

"Spark was too big" :lol::lol::huh:

It sounds more like it's had some "home tuning" done and was running very lean.

Yeah something like that. the spark plug died and i replaced it with the wrong one. apart from that, the odd modifications ive done were running absolutely stunningly.
