Schwinn OCC Chopper not a fun build.

Hey guys,

Today I went down to Mobilgal's (a member here) to start on her OCC chopper. She got a 80cc motor kit, really nice for the most part. Will it last as long as my old Kings? Who knows... The muffler is very cheap, and the sprocket was just silver and not chrome. Looks like the motor is sprayed silver, and then has a clearcoat. Pretty sure she got it from Powerking

Anyway, it seems every aspect of building this bike is a hassle. She bought a adapter for the motor, which we had problem getting the holes drilled. The only bit that we needed was dull. Finally after 4 hours of travel time and jacking around we got the sprocket mounted and the adapter in place.

I see extra work on mounting the fuel tank, rear brake assembly is in the way of the chain, and the chain needs a extra 12 links (anybody got some?). Tensioner will most likely need to be fashioned to fit it better. Bending the exhaust... Trimming the fender, I'm sure I'm missing something else. ANYONE that has built this bike, let me know. Oh it has a 20" rear tire and a 44 tooth sprocket, so what knid of performance can she expect?

If I am not mistaken I believe their is a thread about the occ chopper, if I remember right their was a lot of Mod that has to be done.

I will do my best to find it but no promises.

Amen to that brother. Other than mounting the throttle, everything else has some type of problem. Damn I wish she got a Point Beach, we would have been riding today! But on the other hand, I'll learn more about custom builds...

Sorry

I had no luck finding it....hopefully someone with experience with that bike will jump in.

I have some experience with occ's
my son-in-law (azvinnie) has built 4 or 5 so far
the sprocket and engine both need an adapter (the engine definitely and the sprocket is a lot easier with the adapter)
to clear the rear brake, the tensioner needs to be mounted upside down, pushing chain below brakes
there are 2 different engine mounts available (livefast motors, and a guy called barry something on e-bay), we had probs with livefast's mount and have used barry's on every build (I even used barry's (with another plate I bent) on a deviate chopper I built last year
I hope that wasn't too long-winded, and will try to answer any other ???'s you have

Yeah she got the one from Barry. Best way to mount the fuel tank?

justbill · #7 (**permalink**) 09-07-2008, 07:23 PM

the easiest way seems to be to use 'L' brackets
bolt them to the tank bolts and use self tapping screws to mount to frame
I have used the original mounts turned upside down and screwed to the frame as well, but they always beak around the middle screw to the frame
hope that helped

Yeah, I'm in the middle of an OCC Chopper build right now too.. Livefast sprocket adapter worked fairly easy. Barrys motor mount went on fine. Installed the tank with the supplied brackets upside down. Attached them to the frame with threaded 1/4 20 nutserts.

Exhaust is what has me worried. I'm going to hate spending the $$ for a custom chopper pipe.

Started this one from a bare frame..

Yes everyone Motoschwinn and I have started on my Chopper! Ok...So he's doing most of the work, but he has the experience. Actually he was like a kid in a candy store! Unfortunatley the drill I have was too tall and the cheap drill bits just couldn't cut it. (Literally) So off we went to his parents house where his dad has every tool you could ever need and a huge comfy garage to work in. (Sure beats working in the drizzling rain.) Once there with his dad and him working around the bike, I decided I better stay out of the way. A girl can get hurt getting between two guys and a project!
Anyway, I think Motoschwinn enjoyed working on it, at least until we hit that little snag. We're both of the "measure twice and cut once" school of thought and want to get it right. He was probably more bumbed than I was not to get further on it. I don't mind and set my mind on enjoying the journey. I can wear a parka for my break in rides if need be.

I appreciate the tip on using L Brackets. We were going to have my brother spot weld the tank to the bike, but he's never welded anything and inherited the welder. I'm a little worried he may burn a hole through something. He does stained glass work, so he has a lot of experience soldering and a pretty steady hand. It may be an option later after a few pactice bits. Anyone have issues with the clearance for the spark plug cover? everything fits kind of snug on this bike. I need to put brakes on the front and need taller handle bars. Problem is getting them here fast enough. Anyone in KC area have Ape Hangers that will fit a dual stem OCC Stingray? I tried Acme bikes and they didn't have anything that would fit. Oh I forgot to mention. Several people I work with are interested in building bikes. One guy is done and has been riding his to work everyday for a week now. He bought a Schwinn Point Beach and it went together like a charm.

I'd like to build a chopper one of these days.

Too bad the only ones readily available are the little kids ones

Good to know it's gonna take a bit of work.

Good luck with the rest of the build. Pics please

Oh and for the exhaust, you can use conduit instead of buying the custom one. Use a conduit bender and weld that sucker up and you're good to go
