NC30 Racing

[NoSkill]

Hi there, I'm planning on racing my NC30 in the Bemsee/EDIAsia F400 class this year and got a few questions:

My bike is a stock nc30, and I don't intend on doing any tuning, at least initially, due to setup costs already being quite massive, so I'm going to rebuild the rear caliper (completely seized, got the kit already so just need to get it off the bike and actually do it :p) and I also need to get the exhaust off and find where it's blowing and either get it fixed or get it replaced, then the lockwiring and stuff and the core bike should be fine.

Right, so here are the questions, Firstly wheels, I've been told that the 'tyres to have' are the Pirelli super corsa, which only come in a 17" rear, and that the wets generally come in a 17" rear as well? I've seen the Delkevich wheels on ebay for ~£150, is this a straight swap for the default 18" wheel, and is there anything else I'm gonna need to do to change to 17"?

Secondly, race fairing, where's best to get them from? seen a couple come up on ebay for £130 for what I think is a full fairing set, was planning to buy 2 and keep one as a spare?

Brakes, I've got braided brake lines already, and the stock discs seem fine so was just planning to replace pads and brake fluid, pad wise are EBC HH pads the best option? and for fluid i've been reccomended ATE Super Blue, is this any good and/or there any better alternatives?

Spares, I've got, or i'm trying to get, levers, clip-ons, grips (is it worth getting switch gear?), alternator cover, clutch cover, foot pegs/levers, front and rear wheel bearings, headstock bearings, clutch and throttle cables. Is there anything else that would be very useful to have 'just in case',

Cooling, I believe it has to be just plain water in the cooling system, is this going to cause any problems with just using the stock radiators?

Gearing, I'll be going to Brands Hatch (indy and GP), Snetterton, Oulton Park, Cadwell Park and Thruxton I believe, is it worth changing from the stock gearing overall, or changing gearing per place (considering it's my first experience of racing so doubt i'll truly be able to appreciate the difference anyway?) I'll be replacing the chain and sprockets before I start anyway, and having spares, but dunno whether to have multiple different sets of sprockets...

Any other advice/information anybody can give me?

Cheers for any help :)

Hey mate, im going through exactly the same thing as you at the moment

first you will probably need wets on wheels, bridgestone do 18'' rear wets so you could use your standard 18 for that if you like but for more selection a 17 is what i was recomended, o and the Delkevich will go strait on, no other modding required

in terms of fairings iv heard good and bad things about the ebay ones, but for a fairing and tail unit you looking at about £200, personally im going for an rvf front and rs250/sp1 tail but thats just for looks

brakes should be ok with standard calipers but i personally recomend cbr600rr calipers, they can be got for very cheep too (probably the same amount as you could sell a good set for nc30 ones)

rad will be fine with just water but flush them out before to make sure you get the best from them

cant help you on gearing but if you replacing it all go 520, cheeper and lighter weight, o and i recomend renthal sprockets, there so much lighter than the one i replace (jt i think) it with

O you'll need a transpoder £150 approx, 1 piece leathers and tyre warmers

Good luck mate and hope to see you at thruxton, probably passing me lol

[NoSkill]

Cheers for the reply,

Yep, that's what I was planning, is the front delkevich much lighter than stock, was originally thinking another stock front wheel for the wets (along with 2x 17" delkevich rears), but if the delkevich front is lighter I could get that for the dry's and keep my current stock one for the wets?

Is there anywhere good online to get the fairing (seen Tyga, but that's expensive, and A&R Racing I think wasn't too bad tbh)?

Already got 520 I believe, but yeah was planning on that :)

Where can you get the Transponder for £150? thought it was closer to £250? and yep, got leathers, boots, spare helmet, tyre warmers and generator on my other list (along with van, picking up on saturday, awning, camp bed type stuff etc etc)

Heh, doubt I'll be passing many people :)

Hello,were starting on a nc30 this year,with ng.The bike we got already had 17" wheels on it,they were off a Honda Bros,they were modified but the bloke said it was easy.The bike has super corsa on it at the mo,but were going to put rennsports on it for track days because they are half the price and i have spoken to alot off people who have used them and have said there good.Were running standard bars got some rear sets for £99 off ebay,and have a fairing set off ebay the £130 one and it fits a treat.My son won the supers A British Championship on a mini moto last year and we have found parts for the 30 are cheaper.Been on ebay alot and all parts are avalible and cheap,just the entry fees are a bit off a shock.We have a van a gezebo a camping stove,and a beer fridge (for me),and are looking forward to the coming season,might see you about.

If you go to a 17" rear you'll need to raise the rear end to compensate, the nc30's have pretty slow geometry as standard and really benefit from raising the rear even with an 18" wheel. You can do this cheaply by modifying the radius arm link:

The standard calipers will brake with the best of them if they have good pads and braided lines. Upgrading calipers would not be a priority for me if running on a low budget (assuming the std ones are in good condition). Front tyre will be your braking limit. They rock on my bikes, easy 1 finger stoppies at 100km/h.

Save your pennies regarding fluid, any dot 4 fluid will be fine, higher than this and it will just need replacing more often.

Buy more of those spares with the cash you save!

Jimmer il be doing my first race with ng (thruxton) so may well see your lad on track (i assume it is him riding), noskill we can have a race of our own at the back then

o yeh you may be interested in rearsets for a bit of extra ground clearance or you can gt jack up plates for about £25

Pritty sure the Delkevich are about the same weight as standard but i lighter front that will fit strait in is an nc23 front wheel, there 3 spoke and ment to some of the lightest oem fitting wheels and the 3 spokes look hot, Im planning a 17" bros rear cos you can get them for about £50 but they are quite heavy, mine will be for wets tho so not too bothered

also nc30 suspension will be pritty tired by now and you may want to uprate it, rick oliver sells some pritty good (im told) fork upgrade kits, comes with eveything required, and a good cheep rear shock upgrade is an aprillia rs250 item, also jacks the back up a bit.

To the best of my knowledge I remeber that the rennsports are made in the same factory as the SC3's, with an identical rubber compound so I have always been informed them to be essentially the same tyre.

With cost in mind Id go to the rennsports.

[NoSkill]

Yeah, entry fee's are a big cost, along with all the 'consumables', hopefully it'll all be worth it :p

Cheers, Stickshift, I had seen that linkmod before but forgotten all about it, the end of the thread implies 8mm adjustment (for 35mm height increase) is the way to go, but you originally mentioned 10mm, is it worth going to 10mm to get even more extra height, or will that be too much?

In a bit of limbo with the bike atm, about to move house in a week or two so can't really be doing stuff like taking the suspension apart just yet, but I'll get that done before the racing starts :)

Fair enough on the DOT4, guess if I do manage to get the brakes to fade I can splash out on some better stuff (never managed to get brake fade on any bike or car as yet, but not raced anything yet either :p)

Definately buying lots of spares, scouring ebay for everything I can find/think of :)

read about the NC23 front wheel, can't ever seem to find one online though, might just go for stock front for wets

Guy who had the bike before me re-freshed the suspension (new external-reservoir rear shock as it's the '89 model so don't think it had that as stock, and did 'something' to the forks, not sure what), my thinking is no real performance mods as yet though for two reasons, cost is one obviously and I wouldn't be surprised if I crash (just hope I don't break too much on the bike, or myself :p) and also because I don't think I'm at a talent level where I'd appreciate the difference, I'd rather reach the limits of the stock bike before ploughing money into it if that makes sense :)


EDIT:

Also, got a set of rearsets then gonna have my existing pegs as spares :)

Is that the Metzeler Rennsport tyre that's supposedly similar/the same as the pirelli?

It depends whether you run a 17 or 18 inch wheel. 8mm would suit the std 18" wheel, you'd probably want a little bit more for a 17". Doing this also firms up the rear spring a bit, good for the track.

my thinking is no real performance mods as yet though for two reasons, cost is one obviously and I wouldn't be surprised if I crash (just hope I don't break too much on the bike, or myself :p) and also because I don't think I'm at a talent level where I'd appreciate the difference, I'd rather reach the limits of the stock bike before ploughing money into it if that makes sense :)

Good option.
