new SmartCarb SC3 34mm advanced metering rod carb option

[SpruceItUp]

Yep! Got it all setup today and it is running great! It idles beautifully. I just did some little test rips around the yard and it seems to be pulling very well!

In regards to fitment we finally got it to where it is not hitting the frame whatsoever. It is close, but it is not hitting it. The thumbwheel is now adjustable as well without moving the carb in the boot at all. I'll get some more detailed information once I run it up in Ohio, but so far all is looking good!!

Nathan called me last night to tell me they're shipping the parts out that I will need to install my carb today. He's a really nice guy and I am impressed with the customer service.

Can't wait to try it, glad it feels strong Spruce!

Do the H series installations require any mods to the air boot?

As a rule of thumb we suggest checking for and, if necessary, trimming any rubber lip inside of the airboot that may block the SmartCarb's vent scoop or otherwise direct airflow away from it. Some bikes are worse than others. The Shercos, for example, have a really thick rubber lip in their boots that requires a substantial trim. Some bikes require no trim at all, like Betas.

That said, we're using an extension ring adapter in our KDX kits, which means the vent scoop is positioned lower than it would be in a SmartCarb kit without that type of adapter. From what I've seen the lip in the KDX boots is minimal. Combine that with the use of the adapter and lower relative position of the vent scoop and I would say no, you do not need to trim the boot. But going back to the rule of thumb it's always a good idea to check by looking through the boot into the carb (filter removed of course) and ensure you can see the full scoop or the upper edge of it. If you can't get a direct look a phone camera typically does the trick. That or a bore scope if you have one.

Here's what we're seeing in our long-term H series tester, no trim required:

Thanks for the great feedback with the included picture. That is close, so checking is prudent. I just ordered one, and can't wait, hopefully it won't take forever to get to Alaska, our summers are freaking short. The days are long though!

I stuck my phone camera in my airbox yesterday and it looked like it was clear to me. I could only see half of the vent, but the other half should be the same. I'd say trimming shouldn't be necessary but check just in case.
