If your hawk 250 isn’t running correctly, chances are the stock hawk 250 carburetor is not tuned correctly or using the wrong jets. I have worked on 4 different hawk 250 dual sport bikes so far and all of them had the same issue, not tuned or running the wrong jets. The hawk 250 manufactures have the adjustment screws and the screws to remove the carb cover sealed with plastic coating so you can’t take them out. My first hawk 250 bike I was able to remove the tamper proof screws they have but it does require some tools to be able to get the cover open. If you would like to mess with the stock hawk 250 carb, I have the images posted at the bottom of this blog post.
I purchased my hawk 250 mikuni carburetor and jets from amazon. If you would like to purchase this carb, you can click on the images below (links will open in new window) for the carb and jets. My affiliate link is setup with the links below and if you use my link to purchase the carb, I will get a small commission from amazon and it all goes back towards my hawk 250 and keeping this website going. If you need any help with replacing the carb, please email me and I will do my best to guide you with any issues you are having. I’m not a motorcycle or a auto mechanic but I know my way around the toolbox and how to get stuff done.
The jet size that I’m currently using is a 115 but I recommend getting the package below that has different carb jet sizes so you can quickly switch them out for testing them in your location.
I would also highly recommend swapping out the stock hawk 250 exhaust with the new hawk 250 aftermarket exhaust. Its fairly priced for what you get and the minute you swap out the hawk 250 stock exhaust with the new aftermarket one, you will notice a difference. You can read my post on the hawk 250 exhaust by clicking here.
Here are some pictures if you are looking to modify your stock hawk 250 carburetor, in my opinion the hawk 250 Mikuni carb is easier to work on and its not that expensive to get for your hawk. If you have any questions about the stock hawk 250 carb or the Mikuni one, please contact me and I will get back to you asap.
If you have a dremel then this will be much easier, we didn’t have a dremel and we didn’t want to waste anytime. So using a smallhex-saw will do the trick.
