Hello all, my MC16 rebuild is coming to an end I have been a bit lazy and not updated the project thread but anyway I rode it for the first time recently and I was quite shocked at how good the underdog of NSR's actually is, how light and flickable it is and even with 45bhp it made the most of it.

Which got me thinking, I currently race an NC30 in F400's but I've wanted to race a stroker since I started and after the little ride I had on the NSR I thought it could make a very good race bike, after all we have single disc TZR's from the same era who do well and the MC16 should be light years ahead of them.

Now my main issue is the early NSR is going to want upgrading with different wheels for tyre choice, more ride height, better forks, different barrels, carbs, pipes etc and then there is the issue of spares availability mainly with the cranks which worry me. Would I be better off selling the 16 as a nice clean road bike and searching for a race ready 21 or stick with what I've got and upgrade it which is half the fun for me anyway?

Also does anyone out there still race an NSR? I've searched and read loads of threads but it seems like after 08' not many people post about it. How competitive are the NSR's against the RGV's and KR-1's?

Racing a MC16 would be a cool thing to do. Not if its a really good condition road one though.

Go for it.
Back in the day my standard mc16 could beat a standard tzr but most were tuned and the best ones reputedly were making 55 hp.
That's 20% down on power.
I wasn't a Freddie Spencer but regularly finished top 4.
Go for it, someone good enough could get a win I'm sure.
I'll see how you get on first and then maybe come and have another go, some 28 years later.

I think it would look good with an ND5 fairing fitted and painted up in the factory colours, anyone know a supplier that sells them? I'm not really a fan of swapping to the newer style curvy RS fairing.

The bike isn't mint but it's not a dog either, could be cleaned up into a real nice road bike which it's very tempting to do as I have never seen another MC16 on the road. But if in honest I keep talking myself into racing it even though I'd be starting on the back foot.

I'd probably be racing it in the Two stroke gp series rather than Bemsee who I'm with at the moment as the F400 rules are a bit against the two strokes. So I'd be competing in a class against 250 road bikes and 125 gp machines. My names not Fast Freddie either but I'd like to think I won't be wobbling around at the back, I'd also like to think 55bhp could be achieved on the 16' with a bit of time spent getting the best out of it. I'd only be 1hp down on my NC30 but with a +/- 50kilo weight advantage!

2Smoke raced an MC16 a few years back, and got it going really well. Fitted an MC21 dry clutch to it, tuned it a bit, had some pipes made. It would easily put up a fight with some of the MC18s and MC21s at Donington at our track days.

It's also the lightest NSR250 to start with, and with a bit of development, could be a great bike to surprise some people with!

As you say, an ND5 seat unit (and fairing) would work well on it. I have one that I thought about using on the F3 [if I ever get round to building it], but also a genuine F3 seat, which although battered, will probably take preference. Very similar ideas to yourself!

At least there has been someone else racing one, if it is up and ready for next year I'll definatly bring it along to the trackday and see how she gets on against the other bikes. Good to hear the Dry clutch setup can be fitted, is it just a straight swap or are there some modifications that need to be made to the cases etc?

Im waiting on a set of JHA pipes to be delivered from japan, in MC16 fitment too which seem to be pretty hard to find which is a start towards releasing a few extra HP, I bet it wouldn't be too much hassle getting the bike down to 115-120kg, maybe less if I get some Ali bits made up.

Do you know a supplier for ND5 fairing Andy? I've heard meadspeed might do a full set but I haven't given them a call yet. Are there many differences between the MC-16 F-3 fairing and ND5 fairing? From the few photos I've seen they look really similar. Would be keen to see your F-3 16 in action if you ever do build it, I much prefer the square shape to the older models.

The dry clutch isn't a straight swap, but doesn't take too much to get it to work. As a wild, completely made up guesstimate, I'd say over 90% of the components are a straight swap.

The F3 fairing is actually the stock upper, with a headlight cover, a one-piece lower [belly pan], and separate side panels. Overall, it retains the OEM silhouette.

Not particularly easy to lighten an MC16 much more, I'd say. Some very early NF5 wheels would probably give the greatest saving. Maybe an alloy F3 shock, and hack anything unnecessary off the steel subframe. Other than that, the discs/calipers/forks are all smaller/lighter than any other model, and quite possibly some of the first things you'd want to update!

Glad to hear the majority of the dry clutch is the same, shouldn't be too much hassle making it work. (I hope) :p will be in the market for one as I love the dry clutch tinkle. Bit of performance to be gained too I'd hope.

If my road fairing wasn't in such good condition I'd have just used it as a race fairing, I'm sure a fibreglass one will save a bit of weight though, hopefully removing all the road gear, fitting a set of clip ons, JHA pipes and a few Ali brackets etc should drop a few kilos off it.

I think the stock calipers would be good enough, same as what's fitted to my CBR600F road bike and that's a big old heavy bugger compared to the NSR, unsure on the forks I'd like to think with some better springs and a bit of a mess about with the oil they could be decent. If the worst happens I have got a set of MC21 yokes and NC30 forks/calipers/discs that will be a nice upgrade, very heavy though.

Yeah, that's the "problem" with a fork/brake upgrade, you're instantly adding weight. The Jha's will certainly save a few kilos.
