Get to the Choppa!!!

[Davidisabeersnob]

Snagged this sweet ride off CL for $100. Bought a 212 Predator to replace what's on there. Front disc and rear drum brakes came on it. Needs an engine plate to mount the engine, and relocation of a few tabs... I'm excited to make this chopper roar.

Cheers!

Sweet ride :thumbsup:

The 212 barely fits... And I don't even have the mounting plate in there yet. I may have to relocate the gas tank or buy a new one and mount it elsewhere.

Lose that hideous tank and you'll gain some serious room, you can then move it forward and up higher. I have one of the lager motorized bicycle tank I'd sell for $40 delivered but I have no cap and you would need to tap the metric outlet threads to standard pipe thread. I've taped a few after having to force and seal an outlet in em, the one they come with will NOT flow enough fuel to feed a 212cc. You may also have to add a jackshaft to align he chain, you will likely have a #25 chain sprocket on that rear wheel so chain size will have to be addressed. I'll be taking photos tomorrow and will get you one of the tank and you can see if it would work for you. There are many tanks out there that would also work well so take your time and find the right stuff. Good luck.

I have the same frame but mine has rear disc :thumbsup: I have used the nipple from the clone tank in those bicycle tanks :thumbsup:

Are you gonna put a performance kit on it?

Are you gonna put a performance kit on it?

That's the plan. Probably going to get it running and make sure I have everything in line, then mess with the engine.

 

[Davidisabeersnob]

Cut off and smoothed out all the useless tabs, and hit it with primer.


I'm a sucker for black wheels...


As you can tell, I'm blackin this bike out.

 

[Davidisabeersnob]

I think I should be able to flip the rear tire, avoiding a Jack Shaft. The mount for the chain tensioner on the right side, will become the mount for the disc brake and the mount for the brake on the left side, will become the chain tensioner. I'll have to get everything on there and see how it lines up, but it should be possible.

Where did you find a #35 sprocket to fit that rim?

Where did you find a #35 sprocket to fit that rim?

Bought one from OldMiniBikes without any holes and drilled them myself.

 

[Outlaw Ace]

I knew you would have to swap sprockets, sounds like you are not a bad hand at fitting parts if you drilled your own sprocket. I bet it will be a cool ride once you're done.

Interested to see this one, I was planning on doing this to mine but was derailed many times

 

[Davidisabeersnob]

Engine mount and jackshaft are lined up and ready to be welded. So close!

 

[BikeWorm]

any new progress?

Made one. Bought a 35 sprocket from OldMiniBikes that didn't have any holes drilled, and drilled them out using the current sprockets hole pattern as a guide.

i got one i just tried to unbolt the #25 sprocket that was on it. all 4 "8.8" bolts snapped in half. yay

I'm curious to see where you run the exhaust without cooking the meatballs, when I threw a predator on mine I was very skeptical

Im trying to make a custom bend and turn that will shoot the exhaust down, almost parallel to the engine, the straight back.

Engine mount and jackshaft are welded on.



Exhaust turned out pretty good. Used the exhaust from the little 49cc engine, used 3/4 pipe to joint the flange and exhaust and welded it all together.
