2018 ec 300 rich

I have a 2018 ec 300 with 37 hours on it. The bike smokes a lot and splooges like crazy. Currently have the stock needle on the top clip with a 38 pilot and 173 main. Plug is black and crusty after a few rides. Averaging 40-50 degrees Fahrenheit 7-800 feet in elevation. Anyone else had this issue?

Have a search coblers.. Topic has been covered more than once.

Stock needle hasn't worked well for most the world for quite some time.

I have read everything I can find and ordered 3 different needles to try. Thanks

No worries. I think you'll find a vast improvement.

Don't forget to double check the float height and carb alignment while changing the needle out.

Cheers and Merry Christmas
