It's all fun and games untill some one puts a thigh out. (Kidding, you cracked me up SpikedFox) Has to be a; Y'all watch this joke in there some where. And good job on out running. I am normally laughing to hard and catch the hits.your gonna have a few issues mounting chain driven with a 3.5hp briggs from the v
balance, sence you have to line up the rear sprocket and the clutch n(or else your goin to the hospital trust me. you gotta remeber how wide that engine is and that you will need a clutch gaurd) on a diffrent note, my dad has a decent casting of a gocart cluch
on his calf...
minibike we buiilt with qa 3.5 when i was a kid. we built it we didnt put a clutch gaurd on it and he specificly said to me.
"dont put your leg over this clutch it will rip it up good, now heres how you ride it."
30 seconds later i was pulling the bikeoff him and laughing my ass off at him. he woulda popped em a good one if he coulda caught me.
I don't like the look. I guess I might have to go with a 2 cycle engine in the V or a friction drive mounted on the seat post. I guess I just like the engine under me.well yeah there are some thinnner four cycles, but if you wanna use a briggs and straton why not mount it above the rear tire and still chain drive it. safer. and you dont have to worrie about obscuring your peddles
Very well said. Truely.I think most of us remember a time when we looked at a motor and then looked at our bikes and tried to imagine them together and we thought to ourselves..."That would be sooo cool!"
My memories of old engines are mostly Briggs, Tecumseh and Kohler and I have fond memories of all of them on various go-carts and mini bikes. Others dreamed of Maytag and I agree that they are works of art.
Now that I am older and I have experienced building many things I can honestly tell you that the memory is fond but the reality isn't that great compared to what you will get with a decent kit. I wouldn't consider putting any of those motors on a bicycle. There are examples if you search for them and while I am certain that there was much pride and satisfaction in building it, (Indeed as there is in any build) I tend to find the results wanting and sometimes even dangerous.
The Chinese motors are magnificently simple little things and if you take the time to get to know them they can be a lot of fun and very rewarding.
If you don't want to "Get to know your motor" you may wish to consider a rack mount configuration as most seem to find these easier to set up.
In all honesty I would have to say that the majority of problems I have had, has been with the bicycles themselves. Strapping a couple of horsepower to many of them pushes them far outside their design envelope.
