jlebh1 Chopper Work
To bad I don't have a first name, it's always nice to address a real person. Don't panic, all can be done. First of all, not being at all familiar with bicycles, I don't know the difference between my first issue OCC Chopper and one from this 'Grubee' guy. First thing, you need 'good' brakes, that means 'disc brakes' if possible, which I couldn't put on the front wheel of my OCC. The original rear brake on my OCC fell apart on second stop. Kind of hard stopping @ 25 mph by dragging your feet, enough said. Now, as far as installing the exhaust chamber, there is some welding required. As the enclosed pictures show The cutting and welding that's required is dictated by your motor placement, and how you want the chamber placed. As the picture shows, I like an 'up swept' look, and I think that the dimensions of the chamber fit my frame almost perfect (my opinion). Its just a cut and fit procedure. I also think it sounds great (not to loud). I got kind of picky on motor placement because I didn't like the looks of the motor being way up high, or to low so I modified the mount I received from the vendor to place the motor right in the middle of the frame. You can use the shifter kit from SBP quite successfully, although I had to extend the counter shaft so that the drive sprocket could line up with the placement of the driven chain ring. To complete the drive system, what you want is a 5sp gear w/freewheel (e-bay) and a axle mount derailleur. If you serious about going this direction, let me know and I'll dismantle my drive line and picture piece by piece the procedure......Byron
