  4. 4 stroke 49 cc air cleaner 1 Star Review

    Not a quick and easy install. Bolts are so short you can't use the suplied washers . The suplied rubber hose from engine block to filter is too large a diameter. After getting it installed the motor ran terrible over 3000 rpm. Put stock filter back on, motor ran fine again.

    SBP Comment: Bob we are sorry the 4 stroke air cleaner did not work out. It seems really odd that yours did not fit, because all the others we have sold fit the engine fine.

    Hello Guys just to let you all know I ordered this Air Filter and it works great - not only does it make may 49cc engine look great it makes the engine work much better I love it. Get one ASAP.

    What I am hoping for is that SBP can get a 12v electric starter for HuaSheng 49cc Pull Start Bicycle Engine that would be so cool to have a electric starter.

    This is an Awsome upgrade from the stock airfilter, Great airflow witch alows for pest stress while acelorating and alows smoother, and revs up quicker that allows for greater acceleration!
    :) happy customer

    Really like the look, motor seems to have a bit more oomph when I need it. However, it DOES make the engine LOUDER! Some may like it but between wind noise and now this I can't hear the RPMs of my motor anymore, harder to know when a shift is needed... but I'm still up around 30mph & seems a bit stronger so maybe I should stop being such a crybaby?

    Wow, this air filter is great. The installation of this was a snap. However, don't expect a plug and play performance upgrade. You will need to read your spark plug to determine your specific tuning needs for optimum performance, otherwise it's nothing more then a cosmetic upgrade. The HS49cc stock jet size is .021". When I first installed the filer it was sucking in too much air and wouldn't allow the motor to run properly. I drilled the jet out a little bigger to .024" and it is perfect for my riding conditions. You should get quicker revs and a little more power from mid-range through top-end. In addition, there's no need to buy a separate breather filter; it's just recirculates the crank vent back into the air filter. What a setup, thanks guys!

    I'm just wondering if anyone knows if this will work on a 212cc Harbor Freight Predator 4 stroke motor ? I'd like to get rid of the huge plastic air cleaner without spending big bucks on a B & S type air cleaner. Thanks.

    Are you Running a four stroke? Don't ride without one these Air filters. Easy to install big difference in air intake = faster acceleration, smoother running and great sound for the hard working Huasheng 49cc. Fast shipping and great quality too!
