Want to put HuaSheng on my bike. Can I get more power?

How can you see if it has the hoot box?

what about this one?

Check out nashmotos 50cc Gxh Honda race bike.
We never dynoed it at the races but the stock motor is 2 HP so the fully modded one may make 4 HP at the most.

Be very careful which transmission you buy for a 50cc Huasheng or Honda.
The fact that you are in Poland is going to make it difficult to get the right stuff.

So maybe I should just get a 2 stroke engine?

that kit has a chain pocket bike box that isn't much better than a geared Hoot box.

Do have any small 4 stroke motors in Poland that you could use?
There are several Polish motorized bike builders on this forum.

what is your budget for the engine and parts for your "Derringer"?
 
I would have to look around what we have.
I have the bike covered. The only thing I need to cover is the engine kit.
 
I cannot read anything on that site, but the "OHV 9 KM" looks to be a good size.
I am just guessing by the photo. My accuracy is questionable.

Be careful with any reduction boxes already attached to the engine. The output shaft direction of rotation has alot to do with the kits available to you and how it can be installed in the bike.
It would be very bad if the rear wheel were powered in reverse.

Those reduction boxes unbolt from the motor and would just add to the price.

Better to get a motor without one.

200cc is too big for a street bike. Look to get one at 120cc or less like a 99cc if you can find one.

I have a Huasheng 49cc with all the add-ons.......cam, big bore carb, exhaust, air filter and has been mildly ported. Let's just say I haven't come across a faster single speed Huasheng anywhere.
 
What are the laws in your area regarding engine displacement and power output?
Are you concerned about potentially violating any of them?
Pick the most powerful engine you can get that can fit comfortably in the bicycle frame you wish to use.
Which style of transmission do you want to use? Belt, chain, or a combo of both?
Which style of final drive to the rear wheel do you want? Belt, chain or friction?
Are you going to make all the major bits yourself or use a kit/ modified kit?

All these variables should be considered when choosing the engine.
I cannot read the Polish language. Can you provide the dimensions of the engines you are interested in?
 
I know.
I figured that out when his location says Poland and the link he shared with us was written in Polish.
