ohh boy seen pics of the other side of a c-500 bike that 5hp engine sticks out the side of the bike like 5 feet. iv got another 3.5 non side popper and a 6 horse tecumseh to put on it but i dont know which i want to run.
Yea I never liked the big block engine in those frames, I was all excited when i bought 1969 goat with the 5hp and 2 speed a few years ago thinking how goo goo people go for them it must be a killer bike to ride...it was a let down for me personally. I dont know why they didn't utilize the HS40 engines when they came online for 1968, all I can figure out is an exhaust issue and them not wanting to reconfigure what they already had, or Rupp was not sold on them yet far as holding up. would have been a great combo though for the bike, it fit the frame, like 15 lbs lighter etc..
Also note the foot operated brake, The C500 was introduced after the 1968 lineup was in motion and it came with the foot brake pedal, I think that was done out of necessity to get the bike to stop, single lackluster disc heavy ass engine spinning a huge flywheel. Needed that solid linkage over a stretching cable to get it to actually stop!! It became an option for all the other 1968 models after that and you see them off and on. I am a bit concerned about that as I am attempting to use a 1968 Rupp disc on a custom built bike with a 2 stroke engine modded to produce a solid 7hp using a cable/lever setup :facepalm:
