What will rb designs actually do to the carb and head?

Byte
Buy a head and carb off eBay, have it drop shipped to RBDesigns, then have him ship it to me and I'll mail it to you. That way you would still have your old head /carb and it probably would be cheaper than mailing yours round trip.

BTW I've helped out other Aussies with getting parts this way. It's just a way I can "pay-it-forward" so to speak; helping out another rider!! :supz:


****EDIT****
Rereading here; I think it would be better to send just the head and buy a modded airstryker from Ron Black.

--- Why?

I posted an edit to my thread. I think the BEST way would be to get the modded airstryker from Ron and drop ship an eBay head to him.

I don't know, a couple so far. And some New Zealanders too! Heads, forks, wheels, clutch, triple clamps, etc.. Too much stuff to remember anyway. It's not free, heck it's not cheap for that matter, but I don't charge anything for my time. Just what it would cost. I've built a good crate for the KX front end I sent to Australia once. I have a son in NZ and send stuff back with him when he visits or I take stuff when I visit him.

YOu asked why about the airstryker? It ends up being a better product and if you're buying a replacement stock carb anyway, then why not? Price out both options and see what the difference is. I bet it isn't much. A brand new carb with the pretty hoses and all. Jetted and float set perfect is a real thing of beauty. I was sad to dirty up my airstryker!! Ha!

Also the logistics of either buying one off eBay and having it shipped to Ron or sending your own to Ron directly, it would just be easier to buy the AS right from Ron. BTW, don't forget to order his air screw. It's also a thing of beauty and works great too.

Thanks SkiPro.

What is the advantage of buying a modded airstiker from RB?

What spec would this be?

Why is anything more than 36mm not optimal for this applciation?

The bigger the size carb for the same size engine, the less differential there is in pressure as you open the throttle. The reason a divider plate works is because the carb size is smaller with half throttle or less settings and the vacuum pull is greater. A snappier throttle response. Especially at low engine RPM's. That's why a 220 has a 33mm carb and a 200 has a 35mm carb; the 220 is designed for more low end torque and the 200 for more top end hit. Any larger than 36mm and your boot won't fit. A stock 33mm 220 carb and a stock 35mm 200 carb are the same carb except that the 35 is a larger bore and the walls are thinner. You could see this if you had them side-by-side. Ron takes a stock carb and bores it to 36mm. I don't think you can go any larger and have enough carb body left. Lots of information on here on the Air Stryker. So do a search and then get back with your questions.

OK - so what do I need to ask RB for a modded airstryker?

What head (with spec) should I be buying off ebay?

Byte


So, I ask Ron at RB for a 36mm airstryker carb?
What about the head - what do I buy from ebay?

Check his site and then e-mail him. Tell him you want what everyone on KDX rider is running. He'll know. In fact, he visits this site regularly. Don't be surprised if he starts responding to this thread directly...

Again, do some search on here and review the posts and photos. I know I've posted some...

Yeah, i just answer the Byte's question. I agree with you. I have all the bigs mods on my 220 (RB carb, RB head, VF3, FMF, etc), but I did my rear suspension with Race Tech Gold Valves and put a KX fork in the front with Race Tech Gold Valves enduro too.

Riding the motor with big modifications with a stock suspension it's like a suicide.

Yes - It already has the Wiesco piston inside.

HI Jeb.

Apologies.

I often liaise with another 'Jeb' on KTMTalk Forum. THis Jeb is very highly regarded on KTMTalk and is classed as a SuperModerator.

Sorry to disappoint you but yes - you denitely have a 'twin'.

The valving of a KX fork is for motocross (big hit). The valving for enduro is more for traction, handling and small bumps. When you buy Race Tech Gold Valves, you receive a «owner's number» to have access to the Race Tech website. You give your weight, bike, experience and type of riding and they give you the specs for your valving (and springs).

If you are good in mechanic, you can change the valving by yourself. If not, you can send your fork/shock to a profesionnal suspension company.

The KX front fork is easy to fit in a KDX and is stiffer, stronger, better, have more adjustments and is not old design/technology like the stock KDX fork.
