Hi guys...

Hello I'd like to introduce myself. My name is Alain, I'm from sunny South Africa. My interests are music, motor racing and technology.

Right so here goes:

I went to view an MC21 this morning. The bike is in a dire state but thats ok since it will be a project. The guy heat seized the engine about a month ago and has promptly lost interest. The bike seems to be an SP since it has a dry clutch, is this right?

Then, the electrics all seem fine but the ignition key doesn't seem to be a honda key, it looks like a normal plain jane key, is this right?

Then, the radiator. It's mashed guys. A very large portion of the fins on the front are squashed. This is fine but I need to know if I can have one made OR if an aftermarket alternative is available.

The guy wants R8000 for it which is about GBP 657 (english pounds) in its current state. Ok so given, the bike is in dire need of serious help. The engine doesn't run and the colour scheme is naf to say the least (no offence to repsol colour lovers) so all I'd like to know IS whether I'm better off sourcing a running better looked after machine or if (since it's a project bike) I should go ahead and pay the man.

If it's ok, please read the summary below of my questions:

1) Does the dry clutch make it an SP MC21?

2) No Honda key, only normal key. Is this ok? Are original Honda ignitions
available?

3) The radiator. What do I do there? Cuz it's not usable...

4) What do you think about the price?

5) Before I commit to buying, is there anything I should look for?

Then finally guys, please let me know how I can attach the pics I took so you can all see what it looks like. All and any of your thoughts on if you think I should go for it will be massively appreciated. In advance, I'd like to thank any of you that take the time to answer my questions, you all rock big time

Warm regards,
From South Africa
Alain

Alain, welcome to the forum.

You have posted an NSR related question in the RS (race bike) section, which is the wrong place.

Hopefully site admin will move to the right place

It's always good to hear of an NSR being rescued!How handy are you with tools?A guide to a full rebuild for the motor is detailed in the workshop section.Do you think the radiator is beyond repair?E-bay for a replacement,or classified section here.The search function should find you a lot of answers to your requests.In my opinion-go for it-and haggle down the asking price!

I bought my MC21R 5 years ago for £700 - the engine started, ticked over and ran well, making good power (it had been derestricted with the wire splice but was otherwise stock standard). Mileage was 27,000kms.

Cosmetics were very rough and the front end had taken an impact which had bent the triple clamps slightly so the front wheel didnt line up with the handle bars properly. Otherwise it just needed some love to get it clean and shiny again. And i reckon i paid too much for it to be honest.

I reckon you can haggle him down a fair bit because of the seized engine. Also, because it can't be started you have no way of knowing how well the engine was running or how easily it started before it seized. For all we know it could have an airleak on the crank seals which could be a serious problem. If he won't knock the price down a fair bit, it might be worth holding out until you find a nicer one for sale? There's just a big question mark over the engine in this one.

Both the SE and SP versions had the dry clutch. If its an SP the wheels will have the word MAGTEK cast into them somewhere.

I've got a copied ignition key for mine too, so long as it works don't worry about it.

I'd source a second hand radiator from a breakers or off the internet if you can't use the one on it - this might also be a good reason to hold out until you can find a nicer one.

1.) A dry clutch means that it is an engine with a dry clutch You can convert any of the MC21 engines into a dry clutch with minimal parts swapping. Check out the specifications part of the site to check what your bike most likely will be. (if you've got adjustable front forks and remote reservoir near your oil bottle then it may be an SE/SP, the magteks confirm it's got SP components).

2.) Normal key means it's a copy, or a copy of a copy. No issue there, just like copying a car key. Yes honda ones are available, most likely salvaged offa bike that was wrecked. Not an issue unless you want to have everything Honda.

3.) Replace the radiator

4.) Price wise, I don't know the SA market well enough so hopefully one of the locals can give you more info.

5.) Read through all the technical sections, do your normal bike c hecks and hopefully you'll convince yourself whether or not it is worth buying

You attach photos by setting yourself up an account with an external site like photobucket or flickr, and then add a link to your photos in your photo site.

Hi Alain
The price seems OK for what you are getting. There are plenty of spares available for these bikes. I think you should go for it. Good luck!
Deon

Hey guys...

I uploaded the pics onto photobucket....

Have a look see and tell me what you think. Bear in mind that this is planned to be a project bike so whether it runs or not makes no difference as I aim to rebuild it as a 300cc using one of Tyga's 300 big bore kits...

So in it's current state it does not run. Electrics are fine though...

Thank you guys

Alain

How much can you afford to spend?

Since the motor isn't running, it's very hard to tell if the crank is ok, and that alone could cost you a LOT of money.

Ditto the PGM ignition unit.

Have you priced a radiator? Not cheap.

On the other hand, if you love to do the work yourself, and would have spent a couple of thousand on a properly sorted bike, then I'd say this was probably worth it.

If it has MAGTEK on the spokes, then they alone are worth a bit, so if it all turns out to be a pile of junk you could part it out and make your money back.

What you do have there though, is a complete bike. You should be able to source a running top-end and even a decent crank if really necessary from Yahoo! Auctions (Moriwaki Man in the Members Area can sort that easy enough).

Although there seems to be a number of MC21's being run in South Africa, I don't think there's a huge amount just floating around to simply pick one up at will. It's getting hard to do that even in the UK now, and there must be hundreds of them in the country... at one point between StephenRC45, Racer38, LukeF, and myself, we had at lest 12!

I would ask some really hard questions about how likely you are to find another locally, running, and at what price. You could spend another 6 months or more just looking for a suitable running bike and even then you should really consider at least rebuilding the top-end.

Frankly, your photos are as much use as no photos at all, so no-one can make any educated calls by looking at them. There's probably a lot less wrong with the bike than you think, and it's also highly likely to be an SE. All an SP is at the end of the day is a set of Magteks and a couple of stickers... and about £1000 on top of the sale price if you're mad enough to pay it!

Pretty much nail on head. Even though it won't be a 'true' SP, since no-one seems to know which frame numbers were SP and which are frauds it doesn't really matter that much.

Unless it's a Special Anniversary Edition of course, when you need an extra two stickers!

Hi Alain ,

Send me an email , we have plenty spares and some good contacts . Where are you based ?

Neal

Howzit Alain,

The bike you are talking about is Nick's bike right ?

I know the bike and yes, it is a bit sad. There is another MC21 I know of for sale so whatever you decide to do I am pretty sure we can sort you out....part wise and bike wise.

Cheers
Mario

P.s You can mail me if you want more info on the other bike....mario@wowracing.co.za

Hi guys....Thanks for all the help.

Mario, will let you know how it went. Thanks again buddy.

Neal, tried PM'ing you but the site keeps asking me for my login details

Have you got an email address I can email you on? I'd like to enquire about parts and what you guys have available....Thanks Neal

Then finally would either one of you go to the following link and tell me what you think about these carbs:

http://www.showandgo.com.au/carbie/carb.htm?carb_bf.html~mainFrame

I want a new set of clean (almost brushed look) carbs and since most used carbs are dull and ugly looking from years of use I'm trying to find a high performance alternative out the box....

What you guys think? Am I approaching this totally wrong?

Thanks...
Alain

Personally I'd think you'd be better off spending money on polishing your carbs if bright parts are your thing.

If you go to a different set of carbs, you'd have to do all the tuning yourself to get the jetting right, and not too many people have changed brands and published where to start from.
