And the little brass adjuster in the middle for damping?:-)

OK so I have a kitset VFR400R NC30* for sale. It is disassembled. It is NOT COMPLETE: no motor, exhaust and I can't find the clocks, No fuel tank

What I do have:

Main frame with VIN number and number plate. Rego on hold.
subframe.
Front triple trees.
Two sets of forks (one with good stanchions, one with really good lowers. One looks to have been drilled for emulators but not sure.
stock rear shock.
complete swingarm: including sprocket, disc and master cylinder.
complete set of front brakes m/cyl
a non stock front fairing complete
a replica stock tail unit (I was keeping it for my racebike but no point. It is single seat and has a stock seat pad and tail light to fit.
front rim (good cond) no tyre
one front brake disc - I got this as a spare but it seems OK.
one complete loom.
one incomplete wiring loom One ECU (which has "fucked?" written on it. It is a question not a statement. the issue I was chasing at the time did not improve or get worse by swapping the ECU - it was a carb problem.
some other bits and bobs.

I am keen for all this stuff to begone from my garage. Prefer pickup. Much prefer a single sale.

I have photos but they are on the home PC - will post a few tonight.


I am as yet undecided what to do with my VFR trackbike which is now running well.

Thought I would give you chaps first crack, then put a thread up on KB, tardme is a last resort.

Its on my wish list but think getting a engine be a Issue

Looking at selling my NC30, just wondering what it might be worth..

86~K km.
1991

Previous owner tried to repaint it red, but somehow fucked it up and painted it a metallic champagne colour (or you could call it pink)
Has new plastic red/black fairings (china, but fit all good), so only the wheels and tank need repainting.
Other than the pink bits, bike is very sound mechanically, in last 1000km its had:

new tyres
new rear brake disc and pads
engine has new big end and main bearings (genuine)
valves reshimmed by honda
new valve stem seals (genuine)
all new gaskets etc as engine was apart
new thermostat
new sprockets and chain
coolant change
oil + filter change

Pretty much everything has been done on it, also has braided brake lines, carbon fibre muffler, some aftermarket CDI unit etc.
Looking at selling cause I only have my learners and cops keep hounding me, had to buy LAMS bike otherwise will loose my license on demerits.

Ridden my NC30 around Hamilton for the last 5 years and haven't been pulled up once!

You might be lucky to get $3500 I reckon.

[Icemaestro]

Unsure about Hamilton, but I just sold a bike with similar kms and Chinese fairings, didn't have new tires or pads, muffler was aftermarket but average, paint on wheels was crap - 2700 from memory. So yeah - I would say list at 3200 and should get someone at 3k. Nz hates 'high km' bikes (despite that one running better than my 34km one)

Well if I'm only gonna get 3k for it, I'll just keep it.

There's one on TM for 5.5k, its only done 33km but I'd say mine is probably better mechanically.

Didn't get pulled up for years, then suddenly pulled up every single day.

Over a month ago I was talking about pistons for my brakes. Dealer said they could get them new from Japan in two weeks. Placed my order and then went overseas for 4 weeks. Come back and ask if the pistons have arrived only to find they haven't even been ordered and the guy who was meant to place them had quit last week Another two weeks to wait Should have just ordered online like I normally do.

Is the revlimit on an NC30 controlled by the CDI? Ie, there is no easy way to bypass it? Mine appears to have no rev limiter, wondering if the previous owner diddled with it.

Hi,

I'm not too clear on this as a number of my nc30's have generally stopped at around 15.5k rpm - there is definitely a limiter due to a tab in the speedo that kicks in at 180km/h, that then signals to the CDI to cut power to 2 cylinders. there are multiple ways around this restriction - non stock cdi (ignitech, HRC etc), in line de restrictor such as M-Max or there is an HRC one that plugs between the loom and the CDI, or there is a 'bend the tab in the speedo' way of doing it. I think there is also a resistor modification?

ROM limit - I don't think the inline box modifies the RPM rev limit, only another CDI will do that such as an HRC or ignitech programmable one - take a photo and post your cdi? and how far up does it go? ie did you just get scared it was in the red or it actually went off the chart? from memory 14.5k is the limit, from a quick read it suggests that people generally read up to 15.5 standard ue to inaccuracies in the rev gauge, and the programmable box increase it to 16.5 indicated or so.

I did used to have an nc30 that went to a bloke in chch in 2011 or so which had an hrc cdi on it....kick myself now!

Yeah it dosent have the speed limiter either. I'll get a picture of the CDI box next time im in the shed. I found out it dosent rev limit when it didnt click into 2nd gear properly and bounced backout, valves did meet pistons and such things. Hence why wanting to get the rev limiter to work this time.

Valves met Pistons? Rebuild or replacement engine? So it just kept going past the indicated top?

They very slightly kissed (due to valve float I suspect), which threw a valve shim out (which got jammed and snapped in half). It still rode home, just made a wild tapping noise as the rocker arm was running directly on the valve stem. You could see on the pistons where the exhaust valves touched and removed some carbon ( no damage to pistons.)

I rebuilt the engine, as I stripped it down searching for the other half of the valve shim. The valves didnt seem bent, but I put second hand heads on just in case. New big end and little end bearings, gaskets,valve stem seals etc, new shims etc. It was very much a "while its out and apart, may as well" kind of deal.

Just want to sort this rev limiter deal out, so it doesnt happen again.

Details from when it happened:
