  1. Bikes and Parts Wanted - All Makes
    Anyone know of a good option for a triple tree set that fits 45mm forks and has the dimensions of a ct70 stem? I'm unsure if any other pitbike/model forks would work or could be slightly modified. Thanks!

    I'm looking for a cheap engine. Doesn't have to be running. It could be rusted to hell for all I care. I need it to do some mocking up for a project of mine. Any 50/70 engine will work. So if you have a paper weight in your garage you've been looking to get rid of while getting some money in...

  4. Chinese/Import Minis - General Discussion
    Whatsupp guys, I replaced my chinese (jincheng) CT70's cylinder with a new one. The old one was damaged beyond repair so this was my only option. I have ridden it for about 600 kilometers now (370 miles), but after 10 minutes the engine gets way too hot. When i put some water on the head of...

    I just recently bought a ct70 and I got it running but when I tried to get it to move under its own power, up or down the bike won't go into gear, I hear a clicking sound like it would be shifting but nothing is happening

    Have a CT70 clone with a chinese 125cc motor and was wondering if installing an oil cooler on it will drop oil pressure to a potentially dangerous PSI? Will the oil pump in these motors produce enough PSI to run an oil cooler? I will be using this bike on the street for commuting and for joy riding.

    People act like a 1970s Honda mini-bike should "run like a tank for the rest of your life" but let's get real, it's an antique. I just want it to start and run in a barely-acceptable manner, and at its core it's a lawnmower engine, and the recurring issue with these simple engines tends to be...

    How many times have you come across this? Your new (to you) purchase has a stuck front brake cable that looks like this but when you go to replace it you realize not only that the front brake switch is integral to the cable but, that restoration examples are anywhere between $30 and $60! We’ll...

    Hello, I am looking to see if someone has or knows where my grandfathers 1981 CT70 that he sold is. I am not entirely sure when he sold it, probably either in the 90’s or early 2000’s. The VIN number is JH2DD010XBS201861 and the motor number is 5201833. He bought it brand new and we still have...

    I have two 108s with V2 heads that I've built up from 91 CT70 engines. One has quite a few hours on it, the other recently assembled but ran through a single heat cycle so far. Heads have been re-torqued, o-rings where they should be, and everything performs as expected (love these 108s :cool:)...

    Hey, all! I just swapped a lifan 125cc into my 1994 CT70. I'm trying to find out what each wire from the motor does, and how to match them to the harness on the bike. The schematics I've found online only tell me how to wire up the old 6v CT70s with the lifan's 12v CDI system. I have no problem...

    Hi, I have a Honda 1965 S65, but just always had problems with the engine on it. I had to rebore the cylinder, but still never idled well, also found the 6v system and selenium rectifier swap confusing, second gear is out, etc. Just too much when I just want to ride the thing and have it be...

    Hi all, I'm new to working on bikes, just picked up a '72 CT70HK1 a couple weeks ago. Seems to be in good condition, starts, idles, and runs well up until I'd say 80-90% throttle while riding. Once throttle is opened up past that point, the bike begins to cut out intermittently and I lose power...

    I did a complete teardown and rebuild on my 74 CT70. When I put it back together It runs great. Problem is that ever since the rebuild there is no 3rd gear. It shifts smooth from neutral into 1st and 2nd. When I shift into 3rd it goes into a false neutral with no grinding or funny noises. It...

    I recently bought the fork kit with disc brake from ebay. It didn't come with any instructions, but I was able to get most of it done (I think). My questions are if it's done right. Appreciate any help in advance. First one is on the speedo gear. First I noticed it rubs on the hub quite a bit...

    This one has me stumped. I bought a bike in a box which needed a new top end. Put that on with a stock Keihin carb, and it runs decent, but the sucker will not hold idle. I'm holding the throttle about a quarter turn open. LET ME CLARIFY: The bike itself will idle, as long as I hold the...

    My little 1970 Red Honda 70 that I custom restored was stolen for the 2nd time on December 13th, 2015 from the Brentwood area of Los Angeles and I'm still hoping it will turn up. If anyone happens to see it listed for sale online, or recognizes it from somewhere, PLEASE let me know. REWARD!!!!

    I picked up 4 ct70s frames with quite a bit of parts. Fast forward putting 1 together and the front wheel is not centered, brake side is 1 inch and the other is 5/8 from the forks. I measured and both halfs are exactly the same width, 1 5/8". Is one half supposed to be wider than the other half?
