    I know these are not as popular as our CT70’s but I want to share the build. After going off road this summer on my CT70 it became clear I needed something else to do that with. I stumbled across this by chance with OldCT and thought this may be it. My plans are to make this my street legal off road beater.
    Pat and I spent Sunday afternoon disassembling the motor. There wasn’t enough good remaining to rebuild it. I’m going to use OEM and aftermarket parts to get this running on a semi budget. For now here is what I’m starting with. I will update this thread as often as needed to keep the build current. My time frame is to be able to ride it by summer.

    Too bad about the engine. But congrats on the new bike! Looks like there is some room for improvement o_O
    You're the man Deoodles. I look forward to see what you do with this one.

    Looks like it has LOTS of potential, I’m excited to see how it turns out.

    Keep us updated. Looks like your starting out with some good bones.

    What did you salvage from the engine?

    I managed to save the flywheel but the threads for the puller pulled out so I’m afraid to use it but would if I had no choice. The 1dn3up Honda shift drum, the shift shaft are good. the 4speed trans is different from our ct70 versions. 1 gear is missing a tooth but the rest is good, the stator plate, primary gear for the clutch, the clutch may be rebuildable. Cases are trash, the head could be rebuilt I wouldn’t use the crank I suppose I could hang on to the cyl but I don’t like collecting stuff I know I’ll never use. No stator cover and the clutch cover has a crack/dent in it so trash to me. I have some spare cases and may assemble a 108 stroker. Only missing a head and flywheel.

    For the XL70 I am using a 140cc piranha and will install a custom 12v full wave setup like my 124 CT70.

    16193843_web1_M3-Bigfoot-EDH-190331.jpg That's going to be one of the nicest looking beaters I have ever seen! :D :whistle:
    Yes, that was the worst engine I have ever disassembled/worked on.

    Ray and I really wanted this motorcycle junk yard to have some CT70'S, BUT we had a better chance of finding Bigfoot!

    I may end up needing to rebuild that head for a 108 build. But okay
