To start off hi all im phil from cumbria, uk, i bought my first nsr a few month back it was owned by a chap on here (philandhisjag) think thats right, anyway down to the bike, ul have to bare with me as i dont no alot about these,
Right, its had a seizure lol, new this when i bought it, am i right in thinking replacment parts ie pistons,cylinders ect are as rare as hens teeth?
The next thing i seen a company on ebay advertising rebuilds for nsr,s so i asked and the said roughly £230 to replate the cylinders and supply pistons does this sound about right?
And the final thing ive got it part stripped (bottom barrel off) and the conrod has a little bit of play where it attaches to the crank, is this gonna cause a prob if left?
Oh and before i forget its an ns250 mc11 on a B plate
Hi Phil
Good luck with the rebuild. You wouldn't believe how sorry I was to see it go.........
I never really had problems getting parts for it, I think the pistons and rods are common to the NS400, along with a number of other cycle parts.
There are an number of guys on the NS400 forum that know where to get bits and have some technical info, try www.NS400r.co.uk (I think that's it)
I'm stuck with a bore-stroke VFR750F now. Compared to the NS it feels like a bus - far too heavy.
Looking for another NSR but I'm a bit skint right now....
All the best

Also, when I lived down there (dark days...), I always had no problems getting parts from Nightingales in Rugby. Their number is 01788 573257.
They had all the parts info for the MC11 on microfiche and always managed to get bits (albeit genuine Honda - kerching!), although I never had cause to get pistons and rings....
When you get it running, don't rely on the low oil light - the sensor is bust (I tested it after the seizure) - that's how I managed to sieze the motor.
Hope this info helps

The ns250 MC11 pistons are not the same as the ns400 ones (that are not available anymore anyway). Although the stroke on the crank is the same 400/3 does not equall 250/2.
The con rods are also different.
There are a couple of choices of other pistons you could use and for the money you are going to have to spend, some much more interesting (=more powerfull) options available. PM me for details.
You can do an awful lot worse than PM elegy for some ideas! He has a fantastic Aprilia RS500 (RS chassis, NS motor with 500cc conversion), and knows a lot about the NS motor, and how to best tune it. _________________ Andy.
