    49cc 4G T Belt Kit vs. 79cc Monster 90 Bike Engine Kit

    Although looking at the 79cc kit, it does not come with the wide pedal kit, so that's an extra $30-$50. I'm leaning towards the 49cc kit more, I just don't know if they fixed the oilite bushing issue.

    49cc 4G T Belt Kit vs. 79cc Monster 90 Bike Engine Kit

    Hello there, I just ordered a bicycle after having my 49cc Chinagirl for quite some time. I have put many, many miles on my 2 stroke. Before the 2 stroke, I had an older 4G T belt kit that I experienced issues with the bearing on the transmission. With that being said, I am looking at...

    Thoughts on BikeBerry's FD Kits?

    I'm probably going to be buying a new engine kit by next summer, and well, I would like something cheap and mobile, while reliable. I've had my fun with my 2-stroke, but I would like the ease of a 4 stroke. I don't like the unreliability of the 4 stroke transmissions, and don't have enough money...

    Wide crank for 4 stroke kit

    I just swapped my Hua Sheng back on my bicycle, getting rid of my 2 stroke. I knew that I needed a wider crank, but I just ended up taking off the pedals completely for now. My question is, could I simply heat up the stock pedal arms some type of way and bend them outwards, instead of having...

    Gas spraying out of HS carb

    I really appreciate it! I just have to go back tomorrow and loctite + permatex the side cover, and clean everything up. Also, laugh at me, I'm waiting for my intake manifold to arrive, and I need to order gaskets. I trashed this engine when I got my 2 stroke, thinking that I would never use...

    Gas spraying out of HS carb

    I don't know what you even mean, I've never rebuilt a 4 stroke engine. I have the intake valve at .004, and the exhaust valve at .006 . I just replaced the spark plug and still nothing. Took apart the carb and the float seems fine. What do you mean about the timing? I took the entire engine...

    Gas spraying out of HS carb

    When I say I tried to do the bearing conversion, I ground the shaft too much and just decided to replace it with another 5/8 shaft. I have a Grubee 4G transmission that I will put back on once the engine runs.

    Gas spraying out of HS carb

    I have a Hua Sheng f142 49cc engine, I used to use it on my bike before getting a 2 stroke. I recently decided to fix the engine up, i tried doing a bearing conversion for the one-way bearing, and I had to replace the entire crankshaft. I replaced the crankshaft, used the permatex for the...

    LIFAN 2.5 HP Engine on bicycle

    I previously owned a 4 stroke bicycle engine kit, and now I have been riding around my 2 stroke engine! It's a lot of fun, but I'm looking for the smooth ride I once had before my other engine's clutch crapped out and I ruined the engine. I noticed that homedepot is selling this 97cc engine...
