Purchased these parts in advance for a future maintenance event, so I cant rate performance. They do appear to be of high quality, instructions are thorough and detailed. Packaging is good, and delivery timely.

Couldn’t be happier, finally runs as it always should have. Throttle response, power, starting, reliability are all improved significantly over stock setup.

Love it. Should have got one years ago..

Easy to follow installation instructions.
It has also stopped it from back firing under deceleration.

My wife and I are not performance riders and did not have drivability problems, but wanted to eliminate the vulnerability of an air cut off valve failing as well as add adjustable mixture screws that would be responsive so that riding at various altitudes could be easily accommodated on our two Gen 1 KLR's.
Grant was very responsive to my shipping questions and my kits passed through U.S. Customs fine.
It's a very nice kit - high quality parts in efficient protective packaging. The written instructions that come with the kit were clear and the instruction troubleshooting videos linked are excellent. I like that there are step-by-step instructions as well as a fast track section for those familiar with the carbs.
I do think I’m going to rotate the carbs enough to pull the bowls and do the overflow pipe mod next winter to reduce the chance of hydrolocking the engine if we forget to shut the fuel off.

works great and excellent support + instructions!

Basically didn’t want to do this upgrade but was talked into it and now I have a flying pig! Whole different bike! Can’t say enough about this upgrade, I purchased everything suggested. Best part is this guy Grant, he’s on FB for any help and advice for all aspects of your KLR with videos not just carb

Product is exactly as described with great quality of parts. Not only that I messaged and talked to the owner bck and forth, probably for an hour extremely helpful and nice. If you have a KX 650 I don’t care what kit you have in the car but now I recommend this greatly superior to all other carburetor kit’s.

Product was exactly as described and works exactly as described. Quality parts and not to mention I messaged the owner and we messaged back-and-forth for at least an hour very very helpful and the shipping I felt was quick since it had to come from Canada. I recommend us to anybody who has a KLR 650.

The MCP Carburetor Correction Kit brought my KLR to life. It never felt right before. The differences once installing this kit were astounding. Highly recomend to anyone who owns a KLR.

Great kit, recommend to anyone with a KLR 650. Bike runs great with excellent throttle response. Instructions were spot on with no confusion, very detailed.

The install instructions were nice and easy to follow. Definitely an improvement in acceleration, and pulls harder now. Very happy with the MCP upgrade.

Great communication.amazing packaging and directions. I highly recommend mcp.

The carburetor upgrade gave my KLR more pull off of idle. The motorcycle also runs smoother on midrange throttle.
I am pleased with the results.

Went perfectly in the carb, easy instructions, ran the biek worked great.
