Hawk 250 – Upgrading to 115 Carb Jet and Oil change

Decided to finally swap out the 110 jet with a 115 jet on my hawk 250. It takes only a free minutes to swap out the jets on these carburetors from Hawk 250 shop. You don’t need to drill out the screws to make adjustments or replace the jets. 



Then I did oil change on the hawk 250 and was getting ready to do a quick ride but after checking the bike I noticed a bolt that snapped off. I might have tightened it too much and from all the vibration it just snapped. I need to find a stronger replacement for that bolt and nut. 

Below us a picture of my hawk 250 bike with the bolt head missing. 

This is my buddies hawk 250 and how the bolt should look :). I have emailed therps.net and hopefully they have replacements but maybe I’m better of finding a stronger USA made bolt and nut to relace this China one.

  • hi everyone i got a hawk 250 enduro , and would like to do some performance modifications . has any one else done any modifications to theres? does anyone Thanks. Have installed 30 mm mikuni carb 110 main jet . Opened the air box lid a lil. And changed the front sprocket to 17 tooth so far.

    • Nice to meet another fellow hawk user. I think the only other thing you can get is the exhaust upgrade. I have it posted on hawk250.com/shop and you can try changing your rear to a 45sprocket for some more top end speed. I didn’t lose much low end and I’m 240 and ride up a lot of hills.
