wow wonder if they will do that to an sv in 20 years lol

[squirrel_hunter]

So after keeping them in a crate for some 20 years they take them out and put them in a display box. I don't get it. I thought the point of a motorcycle was to ride it. Bit of a waste really. Shame.

[ChrisSV]

i saw this a few weeks ago.
and although im young, and dont personally remember these bikes, i do appreciate thet fine engineering pieces that they are, and personally consider them pieces of art.
and its for these reasons why people like the ones above p*** me right off, a bike is built to be rode, and Honda built these bikes for people to ride and enjoy, not sit in a glass box to be looked at. For Gods Sake get them on the rode and use them as theyre intended. So everyone can enjoy them as they were intended.

Rant over now :)

[Milky Bar Kid]

That RC30 is lush!

[Alpinestarhero]

If i win the lotto tomorrow, I shall go offer that man £30,000 for the RC30.

and then I shall take it to spannerman for a thourough checking over, and get it running

and I shall ride it and love it forever and ever and ever

an RC30 isn't just for christmas...its for every single sunny sunday of the rest of your life

[blutonium92]

Realy is like watching bike porn!

[jambo]

Like Matt, if I won the lottery tomorrow I'd be inclined to pick up that RC30, however, it being somewhat exotic, if I took it to someone to work on there's very few people in this country who've spent a lot of time inside those motors. They'd be the ones I'd take it to.

Meh, RC30? Nothing more than an RC24 with a few kit parts. Slower on the 1/4 mile too. ;-)

Less than 5HP more[1], not exactly exotic as stock. I'd home service it myself.

RC 30 one of the best racers made wow brings back the memories of my old NC30 such a great handling bike im a way wish i never sold it

[Lozzo]

The RC30 is the bike that tops my wish list if I ever win the lottery.

I came ---> <--- this close to buying a brand new one in 1989, but my then girlfriend talked me into getting married and putting the ten grand savings I had down as a deposit on a house, and we all know what happened to the housing market and my marriage, don't we.

One day I will own one

There are still plenty of RC30's, and even a few NR's being used on the road so one more isn't going to make such a difference. The ones that are being used however will eventually wear out, get crashed or just otherwise spoilt so I don't have an issue with a select few being preserved for posterity so that we can still enjoy seeing them in their original splendor for years to come. I've got a mate who has an NR, an RC30, and a RC45 and he does get them out every now and then, but most of the time he rotates them around the front of his bike shop so we can all enjoy them.

Good morning all.


I used to maintain an RC30, which was quite a buzz after many years of mass produced fodder. My customer bought it for £3000 due to a top end clatter.
They're a bit like a Swiss watch inside - Engineering porn if you like :D

Lifting the cams to shim the beggar was interesting to say the least. They have a scissor gear which is sprung loaded alongside the main camshaft drive gears. You have to insert a locking pin to hold them together when you unbolt the camshaft. The pin hole is 'conveniently' is down the drive tunnel. So it's a 'heart in gob' moment with magnets & rags everywhere.

I turned out that a previous pillock ( I suspect it was the owner) had unbolted the inlet camshaft on the rear cylinder, & allowed the scissor gear to spring back. He had replaced the camshaft without re tensioning the gears, hence the rattle. There was no other damage, after shimming all the valves & balancing the carbs she was sweet. 3k- BARGAIN!

It ran reliably for a couple of years, but unfortunately it was one of the RC30's that was affected by the soft valve seats which was a problem on some. Heads off, & wallet out for the owner, along with the words, 'help yourself'.

It was interesting to work on, the only downside is that everything for an RC30 is around 3 times the price of that of a 'normal' road bike. Head gaskets were a 'HOW MUCH' moment.


Cheers.


P.S. If you ever get to ride one you'll wonder why anyone bothered with fuel injection. The carburation is sublime.

Jambo is right - there's only one person in this country that an RC30 should be entrusted to should it require significant work.

It was indeed Tony Scott who I sent the heads to for the sorting of the valve seats. I wasn't going to trust any of the others in that trade with a pair of RC heads.

There's no mystique to these so called 'Exotic' engines. They're only nuts bolts & components. Exactly the same as any other engine. Just more expensive that's all.

I'm glad there are a few being looked after. Especially considering this muppet!

[fastdruid]

Significant work is something else. :-) Other than that its a Honda, change the oil/filters, balance the carbs, lube everything and just ride it.

Only thing trickier (or significantly different[1]) from a normal service POV to the RC24 as spannerman says is the valve clearances (RC24 uses tappets with locknuts). I am curious as to how someone managed to have the anti-rattle (scissor gears) on the cams missfitted though, all the ones I've ever seen (NC30/NC35/MC17/MC19/MC22/RC24,RC37) only ever sit at most out by half a tooth when off. Although the RC30 may have been rather different in that respect.

Druid

[1] Well apart from almost every part being different by being lighter/smaller etc. :-)

[Luckypants]

Here's hoping for a lottery win this week then! I hope there is someone with a crated RC45 out there for me to 'waste' my winnings on... If not, that RC30 will tempt me!

There are some far sighted dealers (or just plain lucky) out there. :D

Indeed they do on the above models. On an RC30 the teeth are a full tooth out of alignment when the camshafts are removed. hence the need for a locking pin.
Getting the rattly one re-aligned on the bike I worked on was rather tricky, as the springs are of the King Kong variety, & require more than hand strength to get lined up.


Cheers.

A full tooth I presume you mean, having a look at them I can see how someone could just 'put' it in without setting the anti-rattle (I can also see the hole for the pin).

You can see how much sharper the profile opf the HRC cams is.

When my dad has his NC24 in bits, he picked up the transfer gears and showed me how they spun almost forever with just a little bit of input. We both stood there, in the back of the garage, just spinning the gears and marvelling at how beautiful it all was.

He has another NC24 engine which needs some major work, I would like to have it for the engine parts, all the beautiful little parts. It would be cool to throw a load of money at it and have all the parts super-finished (something I read about in performance bikes, "isotropic super finishing" and have some other bits and bobs done to make that standard engine as efficient as possible. Not sur what I'd do with it after, lob it in an RGV250 chassis and hope for the best?

[fastdruid]

The NC24 engine is identical to the NC30/35 engine WRT mounting, want an NC30 frame? I've got one spare in the shed! ;-)

The NC24 makes next to identical power to the NC30, infact the only two real differences are in the valve activation (shim over bucket for the 30/35 and tappet+locknuts on the 24) and its a 180 crank where as the 30/35 is a 360.

Also going back to the original topic, the same holds true for the RC30 over the RC24, the RC24 is 180 degree, the RC30 (and some very very rare RC24 race bikes from which the RC30 was based) are 360 degree.

I'll have to get a picture of my new lathe on. At over a ton in weight she's HEAVYWEIGHT PORN!:D

P.S. Which transfer gears train is that Druid?

Fantastic looking bits of kit, I never knew their price tag was so high.

I played PGR4 last night, it doesn't do the NR any justice.

[ThEGr33k]

Yea, I love the NR, just because its something different and special. Its from a time when Honda thought with its heart and balls (Pretty much ended imo when the VTR stopped racing) as oppose to its head and wallet like it seems to atm.

[fastdruid]

P.S. Which transfer gears train is that Druid?

Not quite sure, Can't remember where I picked up the picture from.

For those that don't know your V4 honda's its a 2 gear set of transfer gears with alloy holders (standard are 3 with pressed steel), ie reverse camshafts, rare as rocking horse poo!

I do hope you are ready for this next one though.....

It's always nice to see the 'naughty bits' that are produced presumably in very small numbers for certain engines.
It does make one wonder why Honda didn't use a two gear train as standard though.

A couple of years ago I did a lot of head work on an R1 track bike. The customer had bought just about every trick bit available. Vernier camshaft sprockets, & big bang camshafts etc. They just looked too nice to put in an engine & cover them with oil :D

I do hope you are ready for this next one though.....



Now you're just showing off old Boy!:D You're making me want to post pictures of all my 'tool porn' just so I can say 'mines bigger than yours'!!:-P

[fastdruid]

Ah, I'm cheating by posting pictures of other peoples bikes, your tool porn at least belongs to you. :-/

I only have this to console me ;-)
