Painted and in the frame.

Engine now smokes evenly on all 3. Previously it smoked more on middle cylinder when cold.

Took her for her first proper run today. Up the the Cat, then via Leek and Buxton. She goes very nicely. The motor is noticeably sharper everywhere with the front threatening to lift easily on the Congleton to Buxton road coming out of the corners. The new engine mount rubbers transmit more vibration at 5k making the bars electric. Gearbox is slick.

All in all, I'm well pleased.

Looking very nice!

What did you use on the pipes?

PJ exhaust paint. Unlike most, it actually works.

As a finish to this thread, it is worthwhile posting up the results of today's dyno session with the NS courtesy of Ian Wright and Don of HB Motorcycles in Dewsbury, Darkest Yorkshire. We wanted to evaluate the engine mounting rubbers before we produce a batch of new ones. Good news is that Ian felt the increased vibes from harder rubbers were fine after a test ride and, more importantly, the engine barely moves. Don concurred which was good to know as he too owns a couple of NS400s.

The dyno results were very pleasing indeed. 60.5 bhp @ 9400 and 34.8 Ft/lb @8,200 rpm. Ian reckons these are the best figure's he's seen from a standard NS400. All the more impressive as the bike has done 30,000 miles and is still running on mineral oil to run it in before switching to fully synthetic. It also transpires the bike is running slightly lean. - see the lower of the 2 graphs - the fuelling should be between the lines! I might jet a little richer which might liberate a little more power....

And here's the video.

Am I pleased? 'kin right I am. 30,000 miles and as healthy as a new bike and miles healthier than the normally quoted 52-55 bhp for a standard bike. Looked after, these bikes are quite obviously built to last.

I must re-iterate my thanks to Ian Wright and Don of HB Motorcycles. Genuine blokes that really know their stuff.

Fantasic results, you must be pleased.

I'd go for a colour change rather than a re-jet. Instant 5rwhp :wink:

Get your dyno graph up soft lad. No point bragging about the size of yours unless you can prove it :wink:

Joking aside, it would be really interesting to know what your Rothmans one is putting out as yours is a relatively new bike.

What...? :shock: Poor little thing would shit its self - probably.

What I can say is that when we went out over to Buxton, my bike easily had the legs on yours. I don't recall there being a huge top end difference, but it pulled off bends much better. I doubt that would be the case now, that's an impressive graph :(

Pull off the bends could well be rider. You're quicker than me on the road. You hustled your ZX9 through bends quicker than I did on a new Blade.

Thanks for the compliment but it wasn't that. I was matching you for speed and gear as best I could. The only thing I didn't know was where your wrist was, but I'm guessing WOT when it mattered.

Hmm. Only way to sort that would be a dyno graph. Get it done :D

I can't do it. :oops:

It's for looking at, not riding. And certainly not for thrashing on a dyno... :shock:

Thrashing on a dyno? It isn't that hard. You hold the throttle open for longer on the road! Honda test them all straight off the production line. Get it done then you'll know how good it is.

I noticed your middle cylinder's silencer has the shield on it. Neither of mine have that, are they frequently removed or fall off?
Also, did you replace the oil lines from the pump under the engine as well as the upper ones going to the intake manifolds?
Glad to hear it runs well and thanks for posting the story & pics.
