    Anyone know of where to find a heavy duty replacement clutch for a 49cc Huasheng with 4GT transmission? The one it comes with broke right away, and they sent a replacement, but you can tell it is just as cheap. Would appreciate any input!

    Which kind of Huasheng is it, the one with a long keyed shaft (clutch comes with 4G) or the one with the short shaft (clutch comes with engine)?

    It's the 5/8'' tapered shaft. The one that comes with the engine.

    The 5/8" shaft engine has a keyway and does not come with a clutch. The clutch comes with the 4G, in that case, a Honda-style 4G or new 7G.

    The short shaft engine (aka "tapered shaft") has the integral clutch. This engine does not have a keyway on the PTO shaft.

    There's not much to upgrade in either case; the clutches are generic. Staton-Inc carries nice versions of both clutches, but their site is down atm.

    Nuts. I thought that may be the case after searching and searching and coming up with nothing. Thought I'd found a good replacement at bicycle-engines.com, but the sent me a clutch that does not even fit the engine they sell. Grrr... Has anyone else had clutch problems?

    Yeah, B-E used to only sell kits with 5/8" keyed shaft engines, but they have obviously changed that in the last year.

    Their current 4G kit states "Tapered 1/2" drive shaft with factory OEM centrifugal clutch"
    which means that the replacement clutch they sell in their parts section won't fit. That clutch is for 5/8" shaft engines.

    There isn't a whole lot you can do with the type of clutch you have besides change springs to modify engagement speed.

    We thought of switching the springs too. One forum we read suggested 1/4'' #35 springs. Any clue on where we can find those? Been to the small motor places in our town and no luck. Thanks for all your help by the way.

    Like I said, Staton-Inc carries all that stuff - clutches and clutch parts. Their site was down when I checked earlier, but it's back up now.

    Here's a link to their heavy-duty clutch for your engine:
    http://www.staton-inc.com/store/pro...ng_Zhongtian_142F_49cc_Four_Cycle-1676-0.html

    If you look through their site you can find just the springs, many different flavors of engagement. I don't know what works with what, but Staton-Inc will.

    I can sell you an EZ clutch set up for $279. & the tapered shaft adapter for $35. That's shipping included. If you're outside the U.S. I'd have to find out if shipping is more.

    Seems like a $314+shipping Q-matic gearbox is kind of steep when OP is just looking for a good clutch for his 4G.

    Granted, few clutches are better than the MaxTorque in the Q-Matic, but a 4G with proper clutch with always out-accelerate a Q-Matic.

    He said he would appreciate "any" input. I don't care if he buys it or not. I was just offering. That price is cheaper than the suggested retail price & he sounded like he was trying to save money..

    Right Jay, but, taking a note from your own pedantry, he said he was "looking for a replacement clutch for a 4G" and "would appreciate any input".

    One would typically deduce that he's looking for any input on a 4G clutch.

    Your EZM kit doesn't fit a 4G. Your EZM's clutch doesn't fit a 4G. Nothing about your EZM fits a 4G.

    If he was looking for something to replace a whole 4G, you'd be onto something :goofy:

    Cheers, my friend.

    Thanks Aleman, that's exactly what I was looking for! I appreciate your offer jb, but that's a bit out of my price range. Especially since that's nearly what I paid for the entire kit.

    Out of curiousity, have you ordered from Station Inc before?

    I have, yes. I've done business with Staton-Inc since 2007, but I haven't ordered anything from him in 2 years.

    Staton-Inc has been around since the 1980s and is probably the oldest company catering to MBers that's still around.

    They aren't always the most prompt, but they typically do good work.
