    Clutch Problem - Tapered Shaft

    Hi All,
    I'm brand new to the site and I have a question.
    I just purchased a minibike, which I was told was a Grand Prix. My problem is that the clutch was all hosed up and when I finally got it off I see that the shaft is tapered for the first 3/4 of an inch and then it measures .80" for the remainder with NO Keyway. The motor is a Honda G200. It appears the previous owner just pounded the Max-Torque on and tightened the bolt. Anyone have any ideas? I have built several go-karts, but never had an engine with a tapered shaft. Should I just forget it and head to Harbor Freight?

    Thanks

    That sounds like it is a generator motor.
    One option is to take the crank out and have it turned down by your local machine shop.
    The machine shop in our area charges about $40.00

    Go to harbor freight and get the 6.5hp motor. Sell the motor you got to help offset the cost of the new motor.

    Welcome to the site! Given the fact it's a Geniuine Honda that's a tough call, I'd check on having it machined down and a keyway cut. The HF clone pales in comparison to the real thing but if you're in a hurry just get the clone. If you're in the Honda cheap enough just keep it and build a performance engine out of it with a new or machined crank!

    Thanks guys.. I was afraid of that. I think I'll opt for the Harbor Freight for now or possibly I can pick up a Briggs and then see what I can do for the G200. I like the idea of building it up for a later installation. I figure the motor was free given the cost of the bike.

    That's the minibiking spirit! That Honda will make a fine performance engine, the clone will be fine for now. I have two and they take a hammering, so far so good!

    Thanks for all your inputs. Someone mentioned that HF is having a sale this next weekend and the 6.5 motors will be $99. If so, I will probably pick one up.

    Tom S., Yep another Portlander. Live up by Sunset High School.

    Thanks again.

    Picked up a 6.5 clone last weekend at the HF Sidewalk sale. $99 and they took the 20% off coupon. So for $79 it's worth a shot. I'll get back to the Honda G200 at a later time.
