Hawk 250 help
Hello my fellow riders. I am one payment away from owning my own Hawk 250cc enduro. Today was the first time I had gotten to ride it. I know a little bit about it but not a whole lot. So anyways today was my first test drive and I liked it but it seemed to bog down and wouldn't take me and my 100 pound girlfriend up a hill is that normal. And the engine would not like it wasnt tuned right. And if I didn't keep on the throttle it would cut off even after I adjusted the idle. It only has 278 miles on it so I'm hoping it's nothing major. Can anybody give me some insight on these issues I'm having

So it's a used bike. Most likely, the original owner hasn't done any carb tuning or valve adjustments. I'd start there.

The carbs are jetted super lean from the factory, the usual fix for this is to cut it open and stick a 110 main jet in there or replace with mikuni with 110 main and 30 pilot.
How fast were you going up the hill? They don't have a whole lot of oomph past 50mph or so. Check out Motocheez's mods list for the hawk. He also has done a ton of youtube videos that show how to mod it: https://sites.google.com/site/motoch...-250-resources https://www.youtube.com/channel/UCfs...sZwINrc4KSbAlQ |

Adjust valves first before any carb tuning. These are tourquey little machines so it should still pull you and your lady up hills. Assuming you are not a 400 pound giant.

Also, check your air filter, it may be soaked in oil, due to the breather tube feeding into the airbox with nothing to block oil mist. That would make it run way too rich, causing bogging. You can either try to find a stock filter or a Briggs and Strat filter fits: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 |

Be methodical and check everything mentioned here by the others. The point made about the choke position is actually a very good one. Make sure you aren't riding with the choke in the half or full position, because that would be like trying to drive your car with a rag shoved in the intake pipe.

I'd start with replacing or cleaning the air filter and fitting a new spark plug.
