I know my original bike is as it was bought first hand. Maybe to the owner, a buyer, or a collector. ![]() It comes down to this: there is a difference between a bike that is in original condition with a known history and one that is a restoration that may be set up slightly different and have reproduction parts. So what is right? Maybe the brochure shows, but Bonanza may have switched the way they set them up at anytime. Gee, when I restore my second bike, which side should I put the rear sprocket and brake on? I guess when it's a restoration and you use the jackshaft and it has brake cable clips on both sides, you can do it either way. Notice different clutch covers, different mufflers, etc. My bike has some differences from the brochures, yet my parts list for "69 models shows what was available. ![]() The fancy bikes sometimes have reproduction parts made to match what the brochures showed on a sales model, but bikes actually sold were sometimes different. ![]() What makes a CR -410 different? You don't know unless you have an original brochure that says what it has that makes it different. These bikes are not with their first owner, and how does one know what is original or correct unless they are the original owner, built or sold them, or had one way back when. One must realize that many of these bikes have obviously been restored and have some reporduction parts. The other difference I have noticed is with the sprocket diameter, number of teeth, differences in the brake assembly, added chain tesioners, and the throttle and hand brake parts suppliers.Īs for the other pictures posted in this discussion. But that tire shows up on all the other mini choppers with the jackshaft frame You can see it in the before restoration, second photo below. The second bike came with a different tread 530圆 Carlisle tire than my first mini chopper. The wear pattern is definitely that of a Tecumseh HS 40. It is not a flat plate welded on top of the tubes. The motor mount plate is different than my first bike. It does not seem to have a serial number that I can find. It has no red round Bonanza emblem nor does it have holes to mount one. It has the Jack shaft brackets and brake cable tabs on both sides. I bought another mini chopper to restore for my boy. I haven't found a serial number on the frame. No, it never had a bonanza red round plate with serial number. No, my bike is not exactly like the brochures and parts list that I still have, but i is exactly how it was purchased from a line of mini choppers at the Harley Dealer where it was bought in 1970. Yes, I put the STP stickers on the engine when I was 12. yes, some of the chrome is new and the paint is Duplicolor Chevy Orange engine paint. yes the motor plate was rewelded in 1972. I have owned my Scout CR 400 (made by Bonanza) since 1970. OK, there are at least two distinct series of frames for the Bonanza mini chopper. My avatar picture is the chopper I've had since 1970. Here's a picture of my second chopper with my spare seat. The exact reproduction seats are quite expensive. Even a bare fiberglass pan is hard to come by to have recovered. I have an extra used seat in fair condition if you need one. I'd use the rear wheel that you've got, but you could use almost anything up front till you can get a kidney bean wheel. Also Bonanzamini makes reproduction parts but are pricey, but excellent. ![]() There's a guy on this site who makes reproduction Bonanza brake drum sprockets and ones that will fit the Azusa Astro wheels if you want the "Torque Thrust" style wheel. All frames came with the little box shape flat bar mount near the headstock of the frame. The tanks were 4 X 7 and were the shorter of the two that Bonanza made. The cylindrical gas tank was an option for the Tecumseh powered model. Look at your engine mounting plate for the wear pattern where the engine would be, even under recent paint, this will tell you if yours was a Hodaka powered or Tecumseh powered bike and which model it would be called. Because the Hodaka uses the jackshaft with the wheel sprocket on the opposite side from the Tecumseh rear wheel set up, they had to be able to set the brake up on either side, hence the cable bracket on both sides. But I think all the frames eventually were made this way, and the Tecumseh powered CR400 version didn't use the jackshaft. Congrats on your frame! Bonanza changed the frame a little bit, adding the jackshaft mounts and adding additional slotted holes to allow for the Hodaka engine.
