NSR250 issues?

[marty]

Had a call from a friend last night. Her 15 year old son has managed to convince his parents that a 1989 NSR250 with the engine in bits was a good buy for him at $1000. So they went and bought it (he paid for it).

It's pretty tidy, with spare fairings etc, but an NSR?

Anyway, does anyone have any hints on known issues, apart from the obvious 2 stroke ones?

[imdying]

Cranks cost big money, barrels are like rocking horse shit. Bad idea for any 15 year old I've ever met.

Probably a safe bike for a 15yr old to own.

If he ever gets it going don't let him ride it, but that probably won't come up.

Hahahaha, from the perspective, you're right! :lol:

[Chrislost]

bahh provided hes not a complete fuck he should be sweet.
probably loose a licence for "un nescary acceleration" at some stage tho...

if hes a twat then hood ornament/new road sign

[Monty69]

Obviously hes a learner so i wuldnt reccommend a NSR as a first bike. Especially 1 in pieces. Ive owned an NSR and a RGV, they seem pretty tame at first untill you hit the powerband at full throttle. The power delivery is so sudden and "all or nothing". Also out of the various 250's ive owned I found the NSR was relatively unforgiving when cornering hard. Its a steep learning curve and to arm a 15 yr old with a bike that can do 0-100 faster than some supercars is not very sensible. On the other hand if hes just gona be taking it to the track then its fine and putting it together will be a good mechanical experience.

No such thing as a 15-year-old boy who isn't a twat.

If he does get it going, I hope the parents take the wise course - deregister it and lock the keys in a safe, then buy him a trackday.

It'd be a pretty rare set of parents who'd take that approach, though, I suspect. Most would either explode in horror at the idea of such a motorcycle in their son's hands, or take a laissez faire approach, shrugging in blissful ignorance of precisely what their beloved offspring would look like smeared across 50m² of state highway.

with engine bits costing more than the bike, now the option of re-powering is being banded around.

any suggestions?

I wasn't. Crashed my bike early on so I spent most of my time as a 15 year old taking the bus instead :p

Pretty much been stuck in similar situations since...

[Bren]

....Yup, buy him a coffin....or a sedate GN250

a four stroke re-power would be good,250cc single ie, xr, cb250rs ,cbx250 etc
etc

[marty]

i like the idea of an xr250, or maybe the cb250 engine. would be a bullet proof engine in a great handling chassis......

[MIZXR]

I can't believe all the people suggesting that a twom stroke is dangerous? how he'll learn respect and probable do it without falling off too. I didn't and didn't start with a slow boat anchor like a GN. You prob;ly think having an HQ for a first car would be silly too.

Why learn on a smaller slow cruiser? when you like SPORTS bikes. Most of the people I know that started on GN and such crap all scared the shit out of themselves when they started riding performance bikes - they were much more dangerous.


Besides if he actually helps build it he won't want to crash it. parts are still available just expensive

What, the pre-RFVC?!? Where where where!!!!!

Would've thought one of those motors would be farkin' useless in an NSR250 chassis. Bullet-proof -- hmm -- and 26hp, instead of 60-odd from the NSR250 lump.

No, it's a RFVC copy. You could have a 2 valve (xr200 scaled up) http://newmanz.co.nz/shop/index.php?main_page=product_info&products_id=8
But give away a lot of the power. It's possible Lifan or one of the others might make a replica, you can buy AX100 and MB100 copies.

[xwhatsit]

Ah ok. You had me all excited when you said `CB/XL/XR' -- didn't think you might've meant the CBX.

Nevertheless it does seem a bit sad to put a sub-30hp thumper into a NSR250 chassis. Why not go the XR600 route :D

I had an RG250 Walter wolf at 17 and that was bad enough. The only bike to ever scare the tripe out of me. Young guys plus two stroke sports bikes equals trouble.

[MIZXR]

Yeh I had a full faired version and on occasion I scared myself but shit I did that in a 1500cc car to. New people that crashed slow as shit singles and fours, pretty sure they scared themselves to. It happens at least you don't have an overdose of confidence when you move to a bigger bike. I thought mine was a great first bike and if id started on anything less I don't think I'd enjoy biking as much now.

Taught me great respect for the throttle you know the one you run along behind the bike holding the bars oh yeah I was 16 and got in a lot more troble in the car.

[imdying]

Yeh I had a full faired versionThe RG250 Walter Wolf is a fully faired version idiot. You're thinking of the RGV250 Wolf, which is a naked bike (the only naked RGV250 iirc).

[gammaguy]

can anyone tell me who the %&$#@## Walter Wolf was anyways?:Offtopic:

[imdying]

http://en.wikipedia.org/wiki/Walter_Wolf_Racing


was a Formula One constructor from 1976 to 1980.

In 1975, the Slovenian-Canadian businessman Walter Wolf had started to appear at many of the F1 races during the season. A year later, he bought 60% of Frank Williams Racing Cars while agreeing to keep Frank Williams as manager of the team. Simultaneously Wolf bought the assets of the Hesketh team that had recently withdrawn from F1. The team was based in the Williams facility at Reading but used most of the cars and equipment once owned by Hesketh Racing....

Tribute to this guy I believe.

http://www.suzukicycles.org/RG-series/RG250-Gamma.shtml


A Walter Wolf model was introduced, available in two colors: Dark Blue and Silver Green. Mr. Walter Wolf was a Canadian oil magnate who had too much money and started a racing team. Suzuki offered the RG250, RG400 and RG500 Gamma models painted in the racing team's colors.

Oh so true. I know the feeling. Let's play a game of guess my age. :scooter:

60 odd horses is far too much for a beginner, I think that when learning you need to cover the basics at low speed and low power, because the guy's got another 70 years ahead of him, hopefully. :wari:

It's his choice, now that he has the bike you'll never seperate him from it. Just make sure he wears jandals. :wari:

I concour, but now I have developed an off button and some maturity I wish I had that bike back. It was wickedly fast.

[judd18]

meh hell be right i bought my first car just the shell and brought an engine,gearbox an manual conversion and hooked it all up it makes like 160KW is rear wheel drive has a heavy duty clutch and i havnt staked it yet and i got it when i was 16 :D all depends. If he pays for everything out of his pocket hell learn to respect as well as every time he jumps on it hell think "took me about two years too put this thing together better not just stak it yet...."

:D

My first bike was a 1988 NSR250 MC18, I was 16....a long time ago.

An 1989 NSR (MC18) is more like 40-45hp peak, unless FULLY de-restricted (thats new exp/chambers, jetting and PGM mods). Even then it'd need to be in top nick to make more than 50hp.

Its a good learner bike, the MC18's are a lot smoother in in power delivery than the earlier MC16's and the RC valves give them fairly good low end.

The broken one is best fixed with a donor NSR engine, a single cyl four stroke engineas suggested would be insulting to the mint chassis.

[flyingbrick]

I made the same mistake a year or so back. bought myself an nsr with engine in bits for something like $300.

It was an MC16.

Managed to sell it once i realised prices and availability for piston barrels and crank.

[marty]

i've got a strange feeling that it is your bike - still in bits, from hamilton? rego?

[lb99]

I had an mc16 when I was 18, it made me into a madman everytime I hopped on it, it was fast, and it handled very well, and had extra good brakes too.
I thought it was easy to ride, fairly smooth for a 2 stroke sporty, happy enough to pootle around town, ok for hillstarts and 2up too, absolutly insane if used in anger :sweatdrop

Yes from hamilton. I got it from Palmy and sold it to a bloke in auckland (i THINK.. could be wrong!) for not much more (was enough to cover collection costs etc) Has/had Rothmans painted fairings.

I did receive an update on the bike- apparently the new owner had repaired a crack in the frame :eek5: and he also bought over new cylinder barrels from overseas as well as some other parts which would have cost him big dollars.

Cant remember exactly but mine also had a spare bottom end and rebuilt carbs.

how do we put images into here?

My profile pic is a big single in an MC18 frame.

A small V twin would be better, vibrations become an issue with big singles.
Not impossible to overcome, just questionable wether it is worth it or not.

The 150 repowering idea is a good one, it is what I'm doing with mine now - for bucket racing.
Thats also a very good thing for a young rider to look at getting into.

Ha! I was looking at that one on tardme as an option for getting all the bits to remount a 2stroke in mine.
Decided it wasn't worth it for me...
