just finished, o.c.c. chopper build

80 c.c. 2 stroke, custom exhaust,(cut up & welded back together) modified muffler, modified engine mount (i used barry's mount off e-bay, but modified it a little), custom gas tank from a jesse james chopper bicycle, all seams, holes & gaps welded closed, fuel pipes added to both sides, smoothed out with bondo, custom metallic black laquer and clear coat, custom made vented gas cap, clear fuel lines with an in line filter, and in line shut off valve.
I painted the cylinder with gloss black hi-temp engine enamel, polished the side covers on the engine, made a chrome stack for the carb. and used the stock filter element inside of it.
shortened the throttle and clutch cables, made my own hidden chain tensioner, modified the rear brake caliper to clear the chain, made a new spark plug wire from an accell 8 m.m. superstock wire, with a 90 degree rubber automotive boot on the end. 10 speed seat on a custom seat post to fit the o.c.c. seat post tube, spaced out the left peddle so it would clear the engine case. 41 tooth rear sprocket, rear wheel chain adjusters added to the rear axle, no front brakes, no front fender, modified rear fender to make it sit lower than stock. all wires soldered together, and covered with heat shrink.
just got it running tonight, and it runs perfect.
i can already tell that this one is going to be faster than my lowrider (which has a 50 c.c. 2 stroke on it). the rear tire on the chopper measures 24" tall from the floor to the top of the tire. the rear tire on my lowride measures 21" from the floor to the top of the tire. so the difference in rear tire size, is giving me a higher gear ratio. i rode it down the street, and at 1/4 throttle, i was probably doing close to 20 mph...i can tell that htis one wants to just go.
i made a lot of custom peices for this bike to make it all work right AND look good. this is my second m.b., but my 3rd. m.b. build.

I clocked it for 60 MPh just sitting there.
Big thumbs up!
 
Looks slick! that pedal chian is pretty loose!

I'm not too concerned with the peddle chain....i don't peddle it, and i use the peddles just for foot rests. I just got it done last night, and i rode it twice. i still need to do a few tiny things to it, and it does need a full link taken out, and probably a half link put in to make it right...but it doesn't fall off the way it is.
 
Looks great. Add a front brake to help protect you and your investment.

Camera Out Of Focus, But Bike Looks Great. The Tank Is A Really Great Touch!! Looks Much More Natural. How Did You Do Your Motor Mount?

i know...it was a late night and the camera (more like me) was having a tough time focusing...lol i was going to get better pics of it today in the sunlight, but i just had too many things to do.
I will try for better pics tomorrow.
I am also going to re-do the gas lines, and filter because i am not 100% happy with the way they are right now.
as for the mount, i used barry's mount (a guy on e-bay makes the mounts and sells them) but my engine has the big mount in the front (for bigger than standard front down tubes). so, my big front mount was too big for the pipe that barry welds to his mounts.
so i had to weld 2 peices of pipe over the pipe that he welded on. I had to use 2 peices of pipe, so that all 3 peices fit together snug and each pipe is welded to the mount.
with this mount, you have to drill holes in the frame for two 3/8" bolts to go through the frame. i really didn't want to drill the frame...but i had to to make the mount work, and so it is adjustable side to side, front and back.
so to add some strength back to the frame where i drilled the holes, i welded steel sleeves inside the frame where the bolts go through for the mount. the mount is 3 peices, and is sandwiches the bottom frame tube between 2 of the peices. with the steel sleeves welded into the frame, i think it should be ok, and they added a bunch of strength back to the frame. plus, with the steel sleeves, the bottom frame tube can not be crushed or distorted when the mount bolts are tightened up good and tight. i also smoothed out the welds on the mount when i got it (they were not the best welds i have seen), and i welded a second bead over the existing welds. i ground the welds down and put a layer of jb weld over the welds, just to smooth things out. i did not add the jb weld for strength, i just added it as a filler (like bondo)to make everything smooth and look nice.

a front brake? what's that?
no REAL choppa' has a front brake...lol

actually, i have modified the rear brake caliper and brake pads and now the rear brake works better than any other v-brakes i have ever seen.
it stops on a dime with no problems.
heck, my other mb has a coaster brake and no front brake, and it stops VERY well.

Great Way To Do The Mount Frame Hole`s.

It Reminds Me Of My Springer Fork On My Stretch Cruiser! The Pivot Bushing`s Are Pressed In And Are Now Loose, A Floppy Scary Situation!

I Plan On Welding Them In With Some Small Dia Ss Rod. The Old Oringinal Forks Were Made Much Better, But Would Cost A Lot More Now.

I Bought Some Aluminum Sleeve`s That I May Use On A Diy Scooter Guy Type Build, That Do Not Have Round Frame Tube`s.

A Sleeve Is In The Center Of Pic, It Has A Split Collar Clamped On. Before Welding Them In, I Will Get Them Adjusted Sideways To Need Mimimum Of Spacer Washers When bolting on the motor plate. Thinking It Will Be A Neat Set Up.
