Well i know i have way too many projects and have been steering clear of EBay to avoid adding new projects to the already long line...... but what are you meant to do when the bike you were looking for finds you?.... well you have no choice but to go with it.

Anyway i had been looking on Ebay for another beach cruiser frame, we dont normally see the original Schwinn variety, just the cheap chinese knockoffs, but even they dont go cheaply in Australia and are not very common at all. I was watching on EBay but most of them went for over $100, which is pretty ridiculous.

Well i saw one at work tonight that someone had thrown out and quickly claimed it. Its forks are broken, hubs are a little rusty, but besides that its quite solid, and as a bonus it has a singlespeed coaster brake and alloy rims. Couldnt get the smile off my face....

Now what to do for a powerplant?

Villiers?...... been done
Briggs?..... would be nice but ive just done a Briggs build
5.5hp Honda?..... destined for the indian

Well ive got this 160cc 2 stroke Victa engine that needed a home..... looks like it just found one

 

[Fulltimer]

Hmmm, looks like it would be an interesting build. How many horses does that thing have? Weight? Got lucky on that bike didn't you!

Yes for once it seems i had luck on my side......

I have no idea of the horsepower but its a 160cc and it weighs 7.7kg (16.97 lbs) dry, with no manifold or carb. They are an Australian produced ( i think ) lawnmower engine and came in a 125cc variety and this 160cc variety. Im certainly njot very knowledgable on them so if anyone knows more id love to hear....

Hillbilly from Australia built an extremely beautiful "thor" replica with a 125cc version of thois engine..... he went really wild with it and made it a very slim profile and seemed to do away with the flywheel and had electronic ignition and its probably hte nicest MB i have ever seen....

 

[harry76]

Thanks man, i was just asking if anyone had some infoe and there it is. Cheers mate

 

[harry76]

I am a little mechanically minded but no expert when it comes to engines...... so do those stats look promising for a MB powerplant?

 

[Fulltimer]

It appears to be a well built engine. I also saw a couple of YouTube videos of that engine on mowers and 1 on a scooter. The engine looked different though.

The mower in that last link was a vertical shaft lawnmower engines, the one im using would be out of a cylinder mower and thus a horizontal shaft mower..... is that what you mean?

 

[Fulltimer]

The links were just to give you some info and ideas. I think that if you do a little checking around you might come up with the carb and manifold. Look around in any old dumps where people pitched junk and old no good lawnmowers. You might get a carb that way.

[harry76]

Thanks man, ill end up just buying a mikuni carb and making my own manifold i think.

Im just deciding whether i want to do another BTR or maybe something different

Harry I just can't let You get hurt. If you restore the bike will be great no doubt. Don't put a 16 HP motor on that frame. It won't hold the power for long. You Will get hurt riding that. A motor over 5.0 hp is asking for it. I got one for Entertainment. I don't ride it over a few blocks at a time. Think about this more

 

[harry76]

16HP? Im not sure this motor would put out more then 5HP, if that. I will be leaving the engine stock, and most likely gussteing the frame, most likely drum brake moped hubs laced to a brand new set of either 24" Tioga or 26" Velocity downhill rims i have not being used.

I also have a 50cc, 66cc and small Villiers powered bike, so this one will likely be entertainment for me too, and as MB's are illegal here in OZ i doubt id get the chance to ride it more then a few blocks before the police ended my fun.

So Saddle does that sound a little better or do you think i need a custom frame or something?

Pretty lucky to find one that nice in the trash. I just saw a 1911 indian board track racer last night. Build Your Own Motorized Bicycle Videos man was it beautiful! I just want to start out with a small 80 cc kit or maybe rare earth hub motor. Good Luck with your project.

 

[harry76]

I couldnt help but have a little play with my new bin find. Im thinking i might build it as a flattracker. I will use a set of 24" Tioga downhill rims that i have and get some really big and tall tyres which should help the look, ill also run a front number plate, make a leaf spring fork, make a tank that sits over the toptube.

Im not building a replica of this bike but it gives you an idea, i think ill do a similar seat setup and simlar tank, but will sit over the toptube and the bottom of the tank will follow the lower of the top tubes.
