MCP Air Cut Off Block Kit - Laser Etched "MCP" - H.S Code 8714.10
Fits All Keihin CV Carburetors with the air cut off valve.
The air cut off block plate allows the cut off to be permanently and securely deleted while adding a little bling to your ride
This Kit also includes the oring to seal the perimeter & Plug for the vacuum supply port
This does change the jetting slightly - see our update kits which include different pilot and main jets regardless of what carb kit is in the carb.
Anyone who looks will know there is MCP in the carb
The air cut off mod can be done with the OE cap but you must epoxy or JB Weld the port, and you must level the cap with 400 grit sand paper on a flat surface using a figure 8 motion. Full instructions come with the kit for both the MCP Cut off block plate AND how to modify the OE cover to work.
United States shoppers please note, the USA put duties and tariffs on all shipments entering the USA from Canada as of Aug 29th, 2025. These fees will be added on the check out screen. The GOOD news is, even with the extra cost, it's still the best money you'll ever spend on your bike. It's that good. The duty/tariff calculator is live and adapts automatically as things change.

Works as intended make sure you get the pilot replacment though because otherwise it doesnt work properly
I finally started the bike after doing all the carb work and I have nothing but positive things to say. Bike started right up no complaints at all. Y'all are doing a great job!! Thank You for your service
Hi Mark
Thanks for the great review, sounds like you did a great job installing, nice work !
Happy motorin !
I just installed the MCP Air Cut Off Block Kit on my 2011 KLR650, and I'm thrilled with how straightforward it was. From start to finish, the whole process took me about 30 minutes. The instructions were clear, and everything fit perfectly. If you're looking for a no-hassle mod that makes a difference, this is it.
Ty Sir !
Clean, well made with oring/plug.
Thank you
Great product. My KLR650 has never run so well. Should have done this a long time ago. The air cut off kit and the adjustable needle jet screw worked perfectly. The u-tube video was also very helpful. Thanks for providing such a good product.
