    Ok, after careful consideration I have decided to make my first build with a 4-stroke kit I just purchased. I got a decent price for a Grubee SkyHawk 4G T-Belt Drive V-Mount Kit, With HuaSheng 49cc Engine. For the bike I decided to go with a Schwinn Clairmont (7 speed, 26 inch), cruiser.

    The install guide says something about tightening the bolts in the transmission and using locktite which I understand but it also says to grease a few parts, what kind of grease do I use, (I was thinking a lithium grease).

    Any advice I can get on this build will be greatly appreciated, This will be my primary mode of transportation since I do not have a drivers license and my new job is 18 miles away and just a bit too far to pedal back and forth to on a regular basis.

    You can go to just about any auto parts store and find a generic can of hi-temp grease for $5 or so. It will most likely be a white grease, but you won't know until you open the can. It will have a dropping point of about 500 degrees fahrenheit. This will work for just about anything. I also recommend servicing your wheel bearings with it.

    I got the kit yesterday. Let me tell you that you CANNOT do this build in two hours unless you are VERY experienced. I bought the HauSheng 142 with the GruBee 4G v-belt Transmission and ran into a few problems.

    1. I broke a sprocket bolt, (overtightened) which is easy to fix from Home Depot
    2. The wide sprocket kit - The shaft is to large to fir the sprocket they sent. I used a Deep well socket and a hammer to beat it onto the shaft but got the key slightly misaligned but I do not anticipate problems with slippage..LoL
    3. The latest snag was the motor mount bolts. They are about 1/4 to 3/8 of an inch TOO LONG. I have two remedies I am pursuing for this
    a. try to find new mounting studs at the local hardware store or lowes with the same threading or take the current bolts to a machine
    and have cut down.
    b. try an old trick we used to use in the boiler room in the Navy. get TWO heavy duty WIDE washers and put a hard rubber grommet
    between them to take up the space. This might help with some of the vibration possibly.
    4. just an observation but the belt drive guard with this lit is the peek a boo type. I found that you have to install the silver single bracket first to make things easier.

    this is where my build stands as of today, I will post more info later BTW, the young lady is my daughter in law who wants to build her own next

    IMG_0017.jpg IMG_0018.jpg Well, another setback. My Darling son forgot to put the battery for the drill on the charger so I cant drill the handlebars for the throttle assembly but I can get that done in another 30 minutes or so. Ace IS the place though......They not only had the mounting studs for the motor but they had them with the same head and allen key size as everything else in the kit. I also got the sprocket assembly bolt replaced.

    now all that is left is throttle assembly, chain, fill her up with gas and try to start her. here is a pic of the build so far. OH, I did have to modify the rear fender, I just had it cut down a little lower than the mount.

    What model Schwinn is that? Unusual seeing the cargo rack welded to the frame. Seems you could make a nice rear chain drive out of that setup.

    I don't know the quality of the welds on the Walmart Schwinns, but I do know that a lot of Huffys with rear racks had crappy welds that broke. I wouldn't be trusting a department store bike to hold an engine to a welded-on rack, especially for chain drive.
