hawk stock exhaust question
If i unscrew the muffler cap and remove the hitech mesh baffle will i reap any performance benefits beyond the more satisfying sound?
Any jetting change suggestions? Running 115/30 now. thanks |
I couldn't tell any difference other than the sound is better.
|
I punched mine out with rebar and probable gained 5 HP on it!
</sarcasm> :-D Seriously...nothing of consequence gained. |
hell, sport rider says it's true (5 hp), in fact sign him up for a late nite infomercial (make sure to use the British accent)

Depending on the design of the HAWK exhaust I'm sure a few ponies can be gained depending on what all you change/remove from the restrictive exhaust, just look how nasty and restrictive the Bashan header is :tdown: and the muffler is no better
First they jam some kind of Coil/Spring/Soda Can inside for your exhaust gasket :ohno: Then they do a crap job and weld the INSIDE of the header making it at least 2/3rds as restrictive as it should be :p |

Yeah my bike came with most if not all that nonsense, the header also has a small sound dampening Baffle/Restriction built in it shortly after the "Big Egg/Catalytic Converter".
I'm sure after I change out the exhaust and tune my 197cc Bashan properly I could see an extra 5 - 20% (if not a little more) HP and Torque across the entire rev range... but it was extremely restrictive compared to others from the looks of things :) |

anything possible, think wide nonrestrictive stainless tube, smooth inner bore. (give me money, lots of money.) someone will take a poke at it, too many people signed up recently (gear-heads cant resist). |

To the best of my knowledge, we don't have dyno numbers on the Hondoid pushrod motor regarding HP gains with mods but they are available for the Q 200 OHC motor. Using that as a comparison,....proper jetting and exhaust mods did give a full 5hp gain from 15 to 20....and for those who have been asking, this is what an FMF Turbine Core 2 sounds like. I will say this...putting a breather, proper jetting and a slip on pipe (no cat) on all of my Hondoid pushrod motors has definitely increased the performance.

Those Zong OHC engines are 'fairly cheap' to get too, under $700 shipped for the air cooled ?223cc? version, and it should bolt right in place of my current pushrod motor/frame mounts if my measurements are correct (drool). Once the Mrs. gets used to riding a motorcycle I might have to swap out for a bigger, better, more powerful Zong OHC engine (or a different bike all together :hehe:)
But back to exhausts, :hmm: does anyone know if the HAWK and Bashan exhausts are "interchangeable"? The inexpensive and free(er) flowing HAWK exhaust would be a nice addition to any restrictive Bashan Dual Sport... but are the measurements and frame design similar enough to work? :hmm: I'm also looking into a FMF PowerBomb Header off a few different Honda's, if any of them measure out right I might be able to pick one up for as 'little' as $150 :lol: |

nice sound... I think you officially sold me on the TC2 for my tt250 in due time. I wasnt sure how a 2-stroke pipe would sound on a four stroke. |
