new SmartCarb SC3 34mm advanced metering rod carb option

[SpruceItUp]

I got a response:

"Hi Ben,

Fitment was more of a challenge in the H series bikes than it was the E series, but even so our prior closest size, the 36mm, had spigots much larger than those of the stock Keihin PWK35.

In our new 34mm SC3 we have perfect fitment and clearance for both frame styles.

Shall we send over an invoice?

Happy to answer any additional questions you may have."

Looks like I'm buying another carburetor! haha

I came here to post the same news! My friend James who is a member here also got this email as well as some others in some other KDX communities.

I believe that's $50 off the regular price, so now is a good time to jump on it.

Although I had read the email from another forum member's (jz05220r?)!screenshot that he sent me, I just now dug through all the spam and promotional emails and read and replied to mine from yesterday.

Of course as you might expect from me, I sent them a long email about tuning parameters and exactly how the bike was spec'd out that they Dyno tested these on, and asking if they dynoed a 220 model specifically, and if it had a modified head, aftermarket reeds, etc....

I advise them that they will see a large amount of 220 customers that probably already have a Ron Black modified rechambered & milled 220R head or a Jeff Fredette milled 220R head, both of which will run a much tighter squish clearance than stock at around 1.0 mm, with the Jeff Fredette heads requiring a bit higher octane, & the RB had running happily on 90 or 91 octane.

I'll see what they have to say. I offered up Port timing specifications as well if they wanted to know much about the 200 versus 220 if they had not dug in that deep, but I think the info with the heads that I gave them and also questioning about aftermarket reed assemblies is probably the extent of what needs to be discussed outside of supporting modifications done to a select few cylinders.

Usually the RAD Valve and the VForce 3 generally require stepping down one size in pilot jet. I failed to mention that detail to them, although I think the effect will be similar to that of the patented CloudForge Venturi design of the smart carb, so maybe it will not change the air velocity any further than the carburetor itself changes it, although it could enhance the air flow velocity even more by going with the aftermarket reed cages.
