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.....

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...

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

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

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.

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

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!

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.

96 NSR250R on Trade Me

**Mokoro** · 27th January 2005, 10:01

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** · 27th January 2005, 10:34

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.
