How does everyone remove/replace the transmission bearings that are in the case? My terminology might be wrong but I have attached pics of what I’m talking about.

I figured I would start a thread about my numbers matching HK1, I picked it up today from a guy out of St. Louis Missouri. He got the bike in a trade with a couple of other bikes out of Illinois. Iv included some pics of the bike. The motor is locked up and the frame has a couple of good dents...

Is there a tool to tighten/loosen the ring around the ignition switch on a CT70 and honestly probably many other model?

Hey everyone I have been working on my K2 restoration when I noticed the gas tank bracket didn’t seem to fit right so I took one off a K0 that I had and noticed it is totally different than the bracket on my K1 or my K2. Is this the correct part for a K0 or did someone put the wrong part on at...

Hey everyone I am looking for a trash case half or whole case. I prefer a CT70 but would take anything CT90,Z50, etc. I am looking for a case or half that CAN NOT be used or rebuilt. I want to practice putting in some HELICOIL‘s before I attempt them on a good case half.

Ok so I just ran into my first problem with my K2 build. I am using CHP K1-K3 handle bars which I used on my K1 build and they worked perfectly but on my K2 the ”ON/OFF & High Low“ switch gets in the way of the throttle twist assembly. My terminology might be wrong but I hav attached pics to...

Hey everyone I figured I would post some pics of my K2 build, I just got her back from the paint shop and started assembling her yesterday. It never fails though when you think you have every part or piece to put one back together you always find something you forgot lol.

Hey everyone I am selling my 1974 Z50A K5. I figured I would list it here before anywhere else. I am located in Garland ( a suburb of Dallas ). This was the first bike I rebuilt, it’s not perfect but it’s not bad. I rebuilt the engine, powder coated the frame, swing arm, and foot pegs, painted...

So I came up on a K0 ST90 in a trade and she’s missing some pieces lol. Does anyone know if the gas tank for a ST90 the same as the gas tank for a CT70? The frames seem to be the same size ( just by eye balling it ), I plan on taking some good measurements this weekend. Any and all info is...

Does anyone know where I can find a NICE set of K2 side badges at? I bought a set off of eBay and they are nice but they are vinyl. I was looking for silk screen on aluminum Like the original was. If anyone know where I can find these at please let me know.

Hey everyone I was wondering if the engine guards on the CT70’s changed over the years? If they did what changed and are they all interchangeable?

Hey everyone I have an issue with the fitment of my K1 exhaust covers. Iv been riding the bike like this for a little while now but it finally got to me and I had to do something about it. If you see my attached pics the lower covers do not line up like the original does. I have a CHP...

I’m just double checking with everyone that my CT70 K2 front fork lowers are supposed to be cloud silver not brushed aluminum? Iv been looking at pic every where and can’t exactly tell. Jeremy Polsons book has some great pics and they all look painted but he doesn’t call it out if they are...

Good morning everyone, Since the K2 has chrome fork ears and I can’t seem to find any I was wondering if I could use another year model fork ears and have them chromed? Is there any other differences between the K2 and other years besides them being chrome?

My terminology is probably WAY wrong but please see my attached pics. Has anyone ever put Helicoil in the threads that hold the cam chain tensioner in place? When I went to took the bolt out of my case the threats came out with it. Has anyone else had this problem before and if so how did you...

I would like to hear everyone’s opinion on gaskets. Please excuse my terminology because I know it’s wrong. The little bit I have been in this hobby I have preferred the “paper” type gaskets but that’s only because the motors that I have tore into that weren’t that “oily” had the paper type...

I have a K1 CT70H motor and I’m trying to buy a stator rebuild kit for it and I’m not sure I I have a HITACHI or MITSUBISHI fly wheel/stator. Iv attached a pic and on another note I haven’t tore into the motor yet so maybe this is something I would see if I had taken apart the motor already...

Hey everyone I’m looking for 2 CT70 intake pipes, I need these for 2 motors that I am working on right now. 1 is better than nothing but I am looking for 2. Let me know if you have one for sale.

Are all CT70 intake pipes the same? My terminology may be wrong but I am talking about the piece between the carb and the head.

Hey everyone I always get confused on the orientation of the cylinder bolts, does the flared end go on the case side or the head side? Iv attached a pic for reference.
