somebody should make an internal 3 speed hub for mb.you could go from 30 to 40 to 50 teeth gear ratio.that would be one wicked shifter kit and easy to install
 
The frame painted in my "paint box".
The rear sprockets, painted, assembled ready for mounting on the bike. Now only the final assembly and test drive remaining dnut

Great build!

The rubber isolator looks like a Husqvarna radiator mount???

I dunno abt that boron stuff... may be low friction but also low adhesion.
I must be old skool... they sold me on pennsylvania crude with long-chain molecules long time ago. Yet I've run amsoil a lot in the mix.
Will even try the opti2 one day.
My kid really likes the Motul oil... if I didn't try the opti2 I'd get more Yamalube.

Hope you can post video of the speed run soon!

Now it atleast it starts to look like a "Bicycle" again cvlt1

As soon as I get everything to work as intended, so I upload a video on youtube:)

First startdance1 First start of the bike, it sounds good, and responds quite well to the throttle, even though the carburetor is not adjusted yet

The video is not as good, holding the camera in one hand and the bike in the other hand!

Today I did a little longer test run, to check that everything works as it should. Since the engine is newly renovated so I drove very carefully. But I did a top speed test, 73 kmh or 45mph, no problem to run between 45-60kmh (28-38mph), I'm pretty satisfied with the results of the the tuning of the engine. Fuel consumption also seems relatively low. 1 liter (0.27 gallons) consumed me at 35km (22miles) it to be about 0.28 liters / mil or (81miles / gallon) which I think is quite okay. The only thing that was not good is, the color was wrong variety, it does not tolerate gasoline so I have to paint it again. but it does not matter that much, I'll make some modifications to the frame that I need to weld .shft.
 
that is an incredible beast of a bike my friend....I am purely jealous! I wish I had something like that. Excellent job. Are you going to make your own ignition system? that should be next!
 
What engine are you using? And is it 2 stroke or 4 stroke?
How long can you ride it (How many miles) without it over heating (most usually don't overheat anyway unless you run them hard)?

Hello! The engine I use is a conventional 2-stroke 66cc China engine , which model or brand I do not know, there are no manufacturing information on the engine ..
I have no problems with overheating the engine, an engine which is correct built, you get no such problems. I've driven over 30 miles full throttle no problems /max

That's nice to hear, it keeps me feeling pretty good about buying a generic engine. :). And it seems like you can go pretty fast on such engine. Where did you get yours?

Ok I see, do you have any other website that sells the motor you have and would be kind of like the same?

I think you can find a similar engine in ad pages here on the forum. What is important if you want an engine with good performance is to build it with new bearings, screws, balance crank, etc.
 
Is that what you did? I am really not new to fixing 2 stroke engines, but I am new to modifying them and stuff, but since I know how they work I think it would be an easy task.

You may have read in my thread where you can see a bit how I have modified the engine with such additional lubrication channels to the bearings .. which helps to get good lubrication of bearings and seals, etc.

The ignition system attached to work very well, tried the spark gap was approximately 10mm spark gap approximately about 20000volt. So I will not change it for now
