    Hey guys, I just upgraded my air filter in my 3ln3 and I seem to be having acceleration problems.
    My bike seems to accelerate heaps slower then before.
    When giving it full gas the bike will creep up pretty slow compared to before, almost like the new filter is restricting air flow... not sure though.

    Can anybody give me a tip (without putting the old one back on) that would solve this issue and give me back the power that the engine had before the filter upgrade?

    This is the air filter I purchased <!-- m --><a class="postlink" href="http://www.uniflow.com.au/contents/en-us/p834.html">http://www.uniflow.com.au/contents/en-us/p834.html</a><!-- m -->

    The best suggestion I have is to check for any air leaks around the carb boots in case you have disturbed them.
    Other than that, partially cover the filter with a various size bits of plastic wrap to restrict the flow slightly and see if it improves things or makes it worse.
