Restricting a VFR 400 NC 30. Alternatives to FI

[Swifte]

I've finally come to the conclusion I'd like to buy and try out an NC 30 (despite all the negatives).

I don't want to restrict with FI fraud international kits.

Does anyone know or have the part numbers I need to restrict a VFR 400?

I know for example (from this forum) that you need the following part numbers to restrict a CB 500 (my current bike) correctly:

Carb insulator LH: 16221MY5710
Carb insulator RH: 16211MY5710

Larger main jets:
Jet #125: 99101GHB1250 (two required)

The above costing a total of around £35-40 from David Silver Spares.

On another note I'm looking to spend more than £1500 on a VFR 400 but would like to find a pristine example with low mileage, what should I be looking when buying a VFR 400?

Just have a watchful eye on ebay. I know there was a kit on there not to long ago. You will only need the 4 washers that go in the inlets as the jets will be fine.

Same as any other bike really, just make sure its got a decent service history and a good owner. 400's in general tend to get abused so just double check everything. Also if it had been sat, you can almost guarantee that the brakes will be binding or sticking. As well as other stuff.

Don't rush into anything, but go into stuff with an open mind!

Result. Just checked ebay.

I'm going to be getting the bike in a few months after christmas, I just wanted the part numbers.

I know you can order the rubber inlets with the washers already in them direct from Honda or David Silvers you just have to have the part numbers.

I did this with the CB 500.

Thanks but I was really after the part numbers like for the CB500 (you can find and order those parts of davidsilvers).

I know you had to up the main jets on a CB 500 from this forum. Do you have to up the jets on the VFR?

[0l0dom0l0]

You won't find the washers already in the inlet rubbers for the VFR. Doesn't work like that. The CB 500 Kit your talking about was a kit from Honda themselves. For the VFR 400 they don't make one.

So basically what I am saying is the part numbers your looking for don't exist.

You don't have to up the jets on the VFR no. Best thing to do is once you have fitted the kit is get it dynoed and check the AFR to make sure its not badly lean, if so then you might want to up the jets a couple of sizes. I don't think you will need to though.

ebay or 400greybikes

i got mine for 8 quid off ebay and got my dad (engineer) to write a headed letter to insurance company saying he had fitted them, or get a garage to .
Worked fine and that peice of paper from fi international has no legal power at all its just a rip off.

Hi

While I can't be certain, I would be astounded if Honda made a kit to restrict the VFR400. While it was officially imported in tiny numbers for a short while (most are grey imports) this was getting on for a decade before the 33hp restrictions came in, and there would be loads of other bikes Honda would (but don't) make kits to restrict long before the NC30 became worthwhile for them.

All the best

If you actually want the bike to be legal then you'd best get it dynoed to check. I can't see any point in slapping some washers in and hoping for the best - worst case, you crash or get nabbed and your insurer or plod discover that the bike is still producing >25kW, like that poor bugger on the SV650 forums.

So why not have a chat with the guys at a local dyno place? See if they know appropriate washer sizes, or know anyone who knows, or how they'd feel about you turning up with a bunch of washers, a drill and round files, and doing several runs over a day to dial it in?

Alternatively, if you can't be bothered getting it dynoed, why bother even restricting it? You'd have no grounds for believing that it was legal - might as well be done for riding Otherwise Than In Accordance at full power than at 26kW.

Hi

Trouble with doing that is after a load of runs and a days effort the bill could easily be the same as buying an FI kit.

I know someone who runs a dyno place and who easily has the skills and tools to fabricate the washers and to test them to get the right size but says it isn't worth the time and effort to screw around doing that even compared to the hideous cost of the FI kits.

All the best

I bought a kit off ebay like everyone else does and got my bike dynoed. Came out at 29 bhp. Perfect. Got a print out and that way if you get stopped you can flash the dyno graph.

If the insurance company had said that to me I would have told them to piss off.

At the end of the day just buy the kit off ebay for a few quid. As both keith and myself have pointed out is that honda do not make the kits so you won't find one through honda.

I spend hours and hours researching the whole restriction business as my parents were convinced that I needed to get a certificate blah blah but I refused to pay 200 quid to have some washers fitted and sign a piece of paper totalling a value of about £1.

I got my bike dynoed as for the 35 quid it was going to cost me it was going to save so much hassle later on.

Then your insurers are being daft pricks. Why give them your business?

And if you made a big claim, do you think they'd still believe your bit of paper, or would it suddenly become a question of what your bike was actually producing?

If you actually care about riding in accordance with your license, then I don't think dynoing a bike is a waste of money. Remember the SV650 chap thought his bike was legal, until plod showed him otherwise.

However, if you're really just after the appearance of legality, then I wouldn't even waste money on washers, let alone a dyno run or an Fi scam certificate - just go with an insurer who takes your word for it, and ride your luck.
