Hi, I’m in need of your help, if you don’t mind sharing some of your expertise. I have the Danish version of the CT70, - a Honda ST50, known as the Dax, which I’ve built myself - all except for the engine that is, which I bought restored. I would like to not alter the original engine, but...

I've got a CT70E 3 speed engine and frame (same machine), if anyone is interested - engine serial number indicates its a 1980. Pretty sure the engine is a runner but have not bench tested it yet (may bench test it shortly). Engine turns over and seems to shift ok. All threads including mounting...

First - newb to the site. Glad I found it. Had been part of the Yahoo Groups sites, but apparently they've gone down. I've owned a 1981 baby blue C70 Passport for nearly 25 years. It currently has around 2,500 miles. I’m on the cusp of retirement, and I want my first post retirement project to...

I recently did a new post at my CT90 blog where I built up an engine using cases I machined so that you could see all of the internal components and how they operate. I also made a video with the engine turning, gears being changed, etc. that people may find interesting and thought I would share...

I have a CT90 blog where I also do posts on CT200's and recently did a post on how to reassemble a Honda CT200 push rod style engine along with adjusting the points and setting the timing and thought I would share a link here in case the information was useful to others working on CT200's or...

Hey guys, I have a 1986 Honda Christmas Edition 50 That I bought years ago. The bike is gorgeous and the chrome is in mint conditon. Unfortunately the engine is missing from the bike. I supposed they had a engine failure or malfunction early on and sorebody never rode the bike. I also bought it...

I have a 1984 Honda CT70 which stops running and stalls when the engine heats up. It will restart when the engine cools. Can anyone offer a suggestion as to the cause of this situation?

I just picked up my first ct70 and it came with a 110 Howhit 3 speed without clutch engine. I can't find anything about them except that the 150cc versions Howhit makes are mainly used on Yerf Dog go karts. I'm not positive on mine being a 110 because I can't find one online anywhere and it has...

I have a 1979 honda ct70 and it runs very nicely however you can here a strange sound in the engine. Like metal hitting metal, however not loud just like something is loose and flapping around in there. You cant hear it over the muffler, and only when you put your ears up to the engine. Just...
