Does anyone know much about 92 NSR250 Super Edition PGM3?

[Zapf]

Just looking at this bike

Does anyone know much about them? How often rebuilds / cost? reliability? parts easy to get?

How to see if engine in good condition?

http://202.21.128.4/photoserver/89/7361989_full.jpg

Would anyone in Auckland who knows 2 strokes mind giving it a once over?

Thanks

[XTC]

If it smokes it might need the rings done??

[Coyote]

I know that it looks awesome

[gav]

What sort of milleage has it done? It should be reasonably reliable so long as it has been run on a top grade two stroke oil? So long as it has been warmed up properly too, but it will be higher maintenance than say a GSX250 or CB250 etc.
Is that the one with the swipe card ignition? May have a dry clutch too, which would make it sound like its about to explode, but really nothing to be alarmed at.

Its done 16'000 k's. not sure what two stroke oil its been running on. What is a good TS oil?

When you say higher maintenance, what sort of things needing done? As I am a n00b on two stroke tech.

its a 91, so MC21 just the model before the swipe card ign, and has dry clutch with without the mag wheel I read.

I wonder how would a NSR250 compair with a CBR250RR type bike.... comments? ideas?

[inlinefour]

But just enough to know that I would like to take one for a really good thrashing :niceone:

[Sniper]

I wonder how would a NSR250 compair with a CBR250RR type bike.... comments? ideas?

Would be fun to test out, my THOUGHTS (thats all they are) would be that the TS would get away on the CBR first off.

Someone correct me if Im wrong

yeah the TS would kick the 4strk, i had a mc18 a few years back that had a few mods nufing major just jetting and airbox etc and a mate had a cbr250rr there wasnt one thing that the cbr was better at....but he still wasnt convinced so we swapped bikes and the TS was still light years faster, lighter, and drank a shit load more gas
top speeds were as follows 1992 cbr250rr 180kph
1989 nsr250 mc18 225kph

as for oil i used Motul fully synthetic...its expensive but i never siezed it.

No I don't, sorry. But thanks for asking! :bleh:

16000k's isnt too bad, expect a rebuild maybe around 20000k's (might only have to be bottom cylinder) I rebuilt my RG at 27000kms....

A good TS oil, is Motul Fully Synthetic (Very expensive, like $60 per litre :crazy: )

As Aaron said, the NSR will leave the CBR behind... The NSR will have almost 400cc IL4 four stroke performance (almost as much as your SV.....) So is a very quick bike...

Send a PM to Hoon he should be able to help you out...

[curious george]

Fluffy cat is the one to ask around here for that one.
He's got the same bike and done a couple of mods......
Chris, don't know where you get your oil, but I pay $60 for 4L fully synthetic Shell stuff...
But anyway, I hope you like tinkering... it's a lot of fun

[MrMelon]

Yeah the nsr would be a wicked fun bike. I ran shell vsx2 in my tzr for 10000km's when I had it and it was fine and only $50-60 for 4 litres. It wasn't too bad on gas and completely raped any other 4 stroke 250's

[Zixxer]

Hi, I've just sold my NSR MC21 SE, exactly the same as that. Use good oil, I'd never use anything other than Motul 600. They are way quicker than any CBR250RR/ZXR which is why they compete against CBR400RR and ZXR400's in formula three. When if they have any damage occur to the bores then the barrels will have to be re nikasil coated, which costs on average about $500 per cylinder. The crankshafts cannot be re-built and cost about USD$1600, there is a place in the UK that can supposedly rebuild them and I'm sure a local engineer might be able to be convinced to have a go. For rings and bearings you're looking at about another $100 per cylinder.

The best maintenance is to always run good oil and always let your NSR warm up before taking it out and never run it over 6000rpm until it is warmed up.

Cheers

[curious george]

If you are local, and want me to have a look at it, I have a 'little thingy' to look inside the barrels to see what condition they are in. PM me

[6Chris6]

Don't know if i would trust it though having the same horsepower as a il4 doesn't make much sence to me

Thats the older NS250R mate.... The one Zapf is talking about should have about 50-55hp at the back wheel.....

[Zapf]

well the reason why I want it is that it'll weight around 130kg's hopefully. and have around 45hp stock, and if I score an expansion chamber then I'll go up to 55~60 hp easy.

Where as a GSXR400 / ZXR400 weights around 160~170kgs I think.

I am looking for something nimble but with power.... cause my SV650 will have around the same power / weight to a I4 400 anyway...

thanks, what sort of rebuilds are most common and what needs replacing? Pistons and rings? anything else? and have you had to do any such things to your NSR while you owned it and for how long (time / mileage) have you owned it?

thanks

[loosebruce]

Not sure if i got you drift Zapf, but are you thinking of selling the SV for the NSR?
If so i reckon you'd be better off keeping the SV for a while yet, yeah sure the SV's power to weight ratio to be similar to the NSR but you'll have to be feeding the message to the NSR to stay on top of the SV, little thing called torque helps a shitload on the road when riding fast.
Dont take me the wrong way man, in no way am i saying you're a slow rider or anything like that, just you need to push a 250cc 2 stroke a lot harder than what you'd have to push the SV. And if you are pushing a bike more, the chances of having a mishap go up a fair bit.
But all in all the MC21 looks farkin hot, but not as hot as the 28 with the single swinger.

:rockon:

Like the one that you own and is in Motohaus????

Exactly! it may not be going but it looks fast just sitting there, another fast looking bike there is that TL1000R :Pokey:

LOL, but yet both of them are probably some of the slowest bikes in NZ :(

HAHAH... :) I was thinking of owning 2 yess.... 2 bikes.. I can only imagen what shit I'll get from my parents seeing 2 bikes...

yea I know about the pushing hard part... but my silly head is thinking that is where fun is :P any reason why your 28 is sitting in Motohaus? Kerry seems very busy and over worked when I went and see him on Monday. care to PM me what you paid for your 28? and what sort of cost .... and how often? I would really like to know / see someone's example before jumping in the it head 1st :P

and that is me who still haven't got the chance to test ride that 2 stroke yet!

[Fluffy Cat]

NSR 250 se,same as sp but no magtek wheels.Adjustable front forks for preload and rebound.Rear shock preload adj comp and rebound adj.Also has dry clutch.everything else same as R model no extra ponies.Hp about 45 as standard.All were restricted via PGM3.Aftermarket system will not make this bike faster as standard!.You need to do the 2 stage wire splice 1st part gives yo the full ignition curve 2nd part is gear position sensor splice,this gives you the 1st 3 gears ignition curves in 4th 5th and 6th gears.As they are retarded.Now you have full power,next fit new pipes and its a different bike.Infact an awsome 250.Handling is very good as standard and there are no surprises ie tank slappers.They dont happen on this bike as standard.Build quality is typical Honda thats good!.
As for second hand purchase.All 2 strokes need more care than 4 strokes.Pistons and rings take a beating,its the ports and the fact that they fire every cycle.So strip down top end and inspect.I would replace the rings and check the pistons for wear.Replace the little end as well and check the crank bearings for movement and float on the con-rods.Put back together and re-set the power valves and you should be sweet for 15-20,000ks.
A great bike with less probs than an RGV.Try NSR world for info lots of info.And TYGA Performance for more info and lots of cheaper parts.
What else do you want to know?.

thanks. you hav summed up all my research in the last 48 hours of searching the web :) and thanks for the personal experience...

and if the bike has now done 16'000 k's I assume i am up for a rebuild soon?

who would u recommend to do the work at good price? and how to learn if I want to?

Sorry time for bed will get to you tommorow....zzzzzzzzzz. :thud:

96 NSR250R on Trade Me (http://www.trademe.co.nz/Trade-Me-Motors/Motorbikes/Motorbikes/Sports-tourer/auction-21067633.htm)

[Mokoro]

Ive heard that the NSR250 motors had a design flaw in that the rear piston takes more heat than the front, and often ceazes. This came from a motor bike mechanic

[Fluffy Cat]

Nah,you may be thinking of the rz500 Mokoro.The hotter cylinder on the NSR is the front one.The HRC and JHA carb kits have the larger main jet on the front to help with the cooling.The NSR is very reliable for a 2 stroke and has a much better designed power valve than the RGV.This gives a broader spread of power than most others in its class.The last pic is the MC28 this version was heavier slower and harder to derestrict than the MC21.But it still looked good,kinda over priced over here though,with prices for an MC28 in good cosmetic nick been about $7000 upwards.

WTF NSR faster than RGV? Naaaaahhh. (well ok, depending on the rider) :ar15:

[bane]

No I don't, sorry. But thanks for asking! :bleh:

shit... ya stole my post - I need a job where I dont have to work...

fwiw, lovely looking bike :yes:

[SPman]

ceazes.! My god, hes done it ! A new compound word! Ceases and seizes = ...ceazes

Without trying.....a genius! <_<

[Zapf]

didn't get that bike... the auction finished before I got to see it .... give me some time to save up some more.... have spend enough $$$ on bikes this pass 6 months. :P

How easy are dented fuel tanks repaired?

[inlinefour]

The NSR can be modded to the point where yes its a better and quicker bike than the RGV.
However, I've never ridden a NSR and from my joy rides on a friends RGV, it goes quick enough :yes:

Hi mate,

Dont know if it helps, but I was told that my 2 smoke engine should last 20000k between rebuilds, as long as I let it warm up, top up the oil every time I fill up etc etc...

quoted a price of around $150-200 for a rebuild, mines a single so might be different for a NSR.......The bike looks like a hell of a lot of fun though!
