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.

Remapped

chip - on an '89 bike?? Similarly with the ported head on a 2T?? If the "porting" was "done before you had it", I'd say whoever sold you the bike was having you on.

Race exhaust - exhausts are quite critical to the tuning of a 2 stroke; putting a race can on it probably is a bad idea.

Bigger carb - what was the original, whats on now, is it set up properly, and why was it changed?

NS125R

I designed a remapped chip myself (i like electronics, its all I can do), and that with the exhaust added just over 8bhp which isnt too bad for a 125; and the carb went from 28 up to 34 and added no power or torque but average fuel consumption went up from 75 to 85mpg. I don't know how but there we are.  I assume it was all set up correctly as I finished all this 6 months ago and its run fine since then until the spark plug went.

And i thought that about porting but the piston and cylinder had a slightly different configuration to that of the standard one in the Haynes manual so i don't know. But yes Fogie it probably was worth a fortune til a couple of weeks ago...  :upset:

Chip

moves the power band for better economy lower down, better torque throughout and top end power,  improves throttle response,  and i took the opportunity to permanently add auxilliaries
