Back on Trac

Hahaha funny joke. But anyways. Hi. Hello. Im new 😬. I’m picking up a Trac Olympic down in Pittsburgh tomorrow and I’m pumped. Kinda wanna make it a touch more off-roady since it has the hydraulic forks and bigger brakes. I know it won’t be a motocross anything, but it would be kinda cool to have something I could rip down a trail or back road on. So yeah. That’s about it. Not to interesting. I’ll throw some photos up if I don’t get abducted going to pick it up.

Toodles!

Did the traditional pre-flight for a new heap. Checked gear oil. Pulled the carb. It was nasty so I threw it in the ultrasonic cleaner (get one. Change. Your. Life.) pulled the plug. Two stroke oil in the spark plug hole and down the intake. Kicked over a few times. Real smooth. Checked. Had spark, but the coil was junky and wouldn’t hold the spark plug wire. I grabbed an extra from a Honda Mini and plugged it in and grounded it. Spark! So input the plug in, put the spark plug cap on, shot up on some carb cleaner, and lo and behold the beast fired and ran! Hopefully gonna get the wiring taken care of.

Yeah that wasn’t me. Well. That one little yellow wire was me, but the rest was someone else. Probably gonna document what I do when and how just cause these bikes don’t have much support, aftermarket or otherwise. Should have it rideable come spring, but that never usually works out.

That’s an M56 / clone right? They were copied from Batavus?

Interested in the ultrasonic...HF has a “bike parts cleaner” size one that I’ve wondered about (like wondered if it was junk). How long do you leave a carb in there for?

Not these ones, that was the generation before. This Olympic would have come with a Daelim DP50 1-speed pedal start.

Re: Back on Trac

These are interesting engines. The cylinder and head appear to be yamaha inspired. They have a pretty decent 3 transfer cast iron cylinder. They have a pretty large exhaust header, and come with a nice quality mikuni carb (although it's tiny). The reed valve uses the 4 bolt pattern shared with polini/tomos/peugeot 103. The clutch and clutch bell are pretty much the same design as the tomos A3, although just a tiny bit larger in diameter. The downside is that the transmissions aren't very robust.

My girl rides a Liberty LS which has an electronic start, put an MLM pipe on it and get a good 45 mphs, not much out there as far as performance pipes but I did find an extra head and cylinder which I ported slightly. I have a Piercard cdi I need to throw on there but I don’t know if I need to retard or advance the stator. All the instructions are in Argentinian. I also put .35 reeds in in and a 40 tooth sprocket I had made for it. She like it but wants a top tank. I’m hoping to find a trac too tank and do an engine swap to keep the electric start which she likes.

Do you have or can you find a .doc, .docx, .odf, .pdf, .ppt, .pptx, .ps, .rtf, .txt, .xls, or .xlsx of those instructions ?

If so , simply go to Google Translate and Upload your instructions .

You'll end up with something you can read . ;)

45 is pretty damn good for a janky ol moped!
