Hello
Hello all. I just order a Hawk 250 DLX EFI. I’ve already started to order upgraded performance parts for it. I’m wanting to leave the stock exhaust pipe in it for now because I’ve not seen any that will work with the efi . But I want to cut it right before going into the stock muffler and putting a stubby tip on it. Does anyone know what size the outside diameter of the pipe is at that location? I plan on eliminating the air box and switching over to filters for both the intake and breather tube what size do I need to order for those thank you and advance and can’t wait to start posting pictures and more details as my build continues!

That's how it goes sometimes.
What are your goals? Another 2hp? With all due respect if you wanted a powerful bike you went the wrong direction. The engine it has is well suited for the bike and generally a well engineered efi bike doesnt leave much power on the tuning table until you go in depth with the motor, which would be silly on these bikes. I think also you will probably be satisfied with the power for whats its worth. |

I'm not hating, just trying to get you to think some of this stuff through before you go throwing money around. Totally understand wanting a certain look or sound. Advice is free and worth every penny. |

If you want to do some real R&D, purchase a laser thermometer. If a mod raises the head pipe temp significantly its a good sign youre running lean. Any popping or fire from the exhaust is also an indicator. With this model being so new, the efi parameters are unknown and reprogramming the fuel map is probably impossible for the average person. On the other hand we will never know the possibilities until someone does try.

Head to the Dual sport subforum and search around for the DLX. I know it's newer so people have some limited experience with it. If it's mostly sound you're after there's probably a way to do that without changing the tune much. Sometimes you can drill the baffles out a bit. If the DLX has the same issue as the carb hawk, the cat inside the head pipe is the most restrictive point for exhaust flow. I'd do some searching before getting to excited one way or the other. Oh and welcome to the forum, please enjoy your stay PS - Motocheez over on youtube has a Hawk DLX but I'm not sure what all he's done to it yet for modifications. Not sure he's touched the exhaust at all.

With the FI models of these 250's, you'll be left out of the performance mod side of things until a piggy-back fuel controller or ECU performance mapping become available, if at all
