ct90

Hey there! I recently picked up my 2nd CT90 barn find. I successfully got the first one running but am running into an issue with my new find. So I went through and did a cam chain adjustment, valve adjustment and adjusted points gap and timing. I get nice bright spark, gas is going to the...

I have a 71 ct90 and I am installing the high low cover. Before I install it the drive sprocket moves freely in gear but when I tighten the cover down the sprocket doesn’t want to move any more. Does anyone know what the problem could be

Hey Y'all, It has come to my attention that the service manual for these bikes only discusses a continuity test for the stator windings and doesn't give any specific values for what resistance they should be. I was also having a hard time finding this information online. I'm hoping this forum...

Hey Y'all, For your entertainment and viewing pleasure, I have for you a project log of our CT90's. I apologize for not posting as I went on these bikes, but hopefully I'll rectify that today and post updates from here on out. Our story begins on February 26th of last year, when I came across...

Hi all I have just gone through my Ct90 and rebuilt the clutch and replaced the drum stopper. Immediately after I removed the left engine cover and replaced front and rear sprockets. I have just gone to start the bike for the first time and it appears to not be engaging the transmission. I...

So I have a 1977 CT 90 that I am restoring I have a very unique problem I need some help with. I got it running really good and now when I drive it I can go for about 5 minutes and it cuts out. I am pretty sure it’s something with the clutch because I can throw the motor in neutral and it will...

The headlight bucket on the CT90 K1 I recently bought (for $200) is disintegrating. Touch the plastic and it cracks. Too much time stored in the sun I guess, over a period of 55 years. I was looking for a new (yellow) one and could not find one. Kirby on this forum generously offered to send...

Hi all. This is my first post here on lilhonda. Last year, I bought my very first motorcycle, and my first real project. Its a 1981 Honda Passport with the DA01E- 70cc engine. I had it running last year around the time I bought it. A friend of mine helped out. The engine would run, however only...

Hello, I recently just bought my first 1968 Honda ct90. It had been sitting for decades, but a friend of mine got it up and running. As I am unfamiliar with ct90s and their semi-automatic transmissions, I had a question. While in gear, I need to twist the throttle a good ways before the bike...

Hi all, First post here! I’ve been having an issue with my newly acquired CT90, that I’ve searched an answer for, but I just keep coming up short. The bike is having an electrical issue with the front lights. The speedometer bulbs were blow, but the blinker and front light(s) were perfectly...

Hey all! I just recently found myself receiving a honda ct90, I believe it is a 1969 k1 because the vin is 211487 (please correct me if I'm wrong) I am pretty certain I need to rebuild a lot of this bike and I would like to start with the carb. Problem is when I go to 4into1 to find the gasket...

My technician pooped out on me after the engines were disassembled, the cranks and tops renewed, and the necessary new parts gathered. I'm left with two disassembled engines. I need to hire someone to assemble them for me; I am bound to make a mistake. Located in North Florida, but I can ship.

Just acquired a early model CT90 in a trade. Bike is pretty much complete aside from needing the engine completely rebuilt (in a box, needs parts cleaned/evaluated) and the wiring all redone. I've never worked on these older horizontal engines only more modern high performance dirt bike motors...

Does anyone know where I can buy an original size flasher for my 78 Trail 90? I’ve included a pic of the one that came out of it and I have a new one that works but it does not fit in the little rubber band that holds the original flasher in place.

Hey guys and gals I have a 78 CT90 that I’m fixing to replace the tires and tubes on and was wondering if there is a trick to getting the old ones off and the new ones on? Any info is greatly appreciated as I have never attempted this before lol.

Hey everyone I’ve been trying to get my CT90 up and going and have ran into a problem I need help with. A little back story I bought this guy a few months ago from the original owner who said “it ran when he parked it 7 years ago”. I brought it home cleaned the gas tank, replaced the battery...
