Hi,
I got a used ct70 clone few weeks back.. And the throttle cable broke so i got another one. Bike runs fine. Thing is, my throttle, when i give it gas it springs back to center. But i can also turn the throttle in the other direction. I believe there should be some stop or screw somewhere but i open up the throttle and there is nothing i can find to make it stop the throttle.. Are these clones built like that?? or am i missing something??
thanks

i recently picked up a clone, its a 2000 jincheng with 363 miles (before i started riding it). when shifting, if i would press the shifter down the whole way, it would go into a neutral between 2 and 3 (from first) and 3 and 4 (from 2nd). i changed the oil after 10 miles, and that seemed to help, but now its doing it again (much less frequently now). i know how to shift a bike with an auto clutch, although it seems to be skipping ONLY when i shift at high speeds (i.e. top end of first or 2nd). im lost and afraid that i have an internal trans problem... i'm using royal purple 30 wt (technically that part should be fine) and i know the trans shares the same oil with the engine. any ideas?

Hi,
So I have a lifan 86cc auto 4 speed (1 down 3 up) and she is acting a bit peculiar. Here are a bunch of symptoms:
1. FInding neutral is hard. The indicator light sometimes lights when its still in gear. when it does find neutral sometimes the light is off.
2. shifting is tough between 1st and second.
3. from any gear to the next, the gear engagement happens when putting pressure on the gear shift, not on releasing the pressure. On all other bikes I have owned the gear engages after releasing pressure from the gearshift.
I have tried adjusting the clutch (screw all in, 1/8th turn out and lock.... no go.
Any insight appreciated.

I'll start from the beginning...You have probably seen in posts where I have written about wanting to do a custom CT...The problem is that from an early age my dad drilled it in my head to keep vintage vehicles original unless it was something like wheels that could be put back to stock or to keep the original stock rebuilt engine if you had a built one that you were running. But to always keep the original color paint,carpet etc. My family was big into collector cars...namely Pontiac's with my Hurst Olds and 62 Corvette being the exception.
Anyhow back to the custom CT that I want to do...I had planned on using either my 71 Candy Gold or my 72 CYS as the basis for the custom, both are straight and very little rust. I just cannot make myself customize them in the way that I want, some people probably think thats silly but it is what it is...I just can't/won't do it and I want no regrets on this project.
Sooo what to do??...Find a nice... "gasp"... clone. Thats not easy. I met some interesting people on that search...One guy was convinced that his Redcat was a very rare to the USA, ST DAX from Japan, no kidding....The dealer had told him that, and being unfamiliar with these thought that was what he had. The dealer had even put a Honda KO decal on it, but did leave the Redcat decals on as well. ?? I double checked with our JDM experts here just to make sure that I was right since I am not familiar with the later ones either. I actually felt sorry for the guy, he had spent a lot on it and thought he really had something special.
The next guy that I met was also convinced that his 2004 Redcat was very closely associated with Honda...in my first 5 minutes at his home he broke a key off in the fork lock. For those of you who have not been close to a clone, the keys are a VERY lightweight aluminum and look nothing like a CT70 key. He spent 45 minutes trying to get the broken key out and then told me he would "Call the Honda Dealership" the next day and get a replacement! LOL!! He was convinced as well that everything about his bike was Honda. It was pretty and very low miles but he wanted a fortune (I thought) for it and was getting upset when I said that even though it was low miles and pretty...it was still a Chinese knock off. He valued it at $800 at the minimum...I was closer to $300. He has had this bike for sale for months with no luck and keeps dropping the price. I left without getting it..HA!
Same story with the next person
The last guy was very realistic about his bike and super nice as well, this bike was also very nice and had been well taken care of. That is the one that I got...I checked all of them for what Bob and Dan have mentioned to be issues and up until this one almost everything that I had read and been told was evident. Bad welds,rust,blisters and heavy paint, play in the steering, play in the rear sprocket hub area, etc.
For me, I knew that a lot would be changed out eventually but I wanted a solid basis to build on and I wanted to use it safely in the meantime. This bike had been sitting indoors for 6 months without being started and even though the gas was good, it did have some particles in the tank and although it started right up (e start) it was easy to tell that it needed some tweaking to run correctly. The bike has 122.9 miles and a new battery. The PO said that it had always had a bit of a ticking sound to it but that he had never done anything about it and said that it was still in the break in stage...He has been very gentle with it and it shows The bike looks like new and the price was more than right and much less than I thought it would be so I brought it home.
The point of this thread is to document the changes and upgrades that I make to it. I will report on any issues and the good points about the bike as I go along.
The bike is a Red 2005 Dirt Dobber 3...The DD-3 is suppose to be a 110 but this one is a 70cc I believe, which is what I was expecting to get. It has 122.9 miles on it and is an electric start (I like that) as well as a kick start. It is a 4 speed semi auto. It came with a Manufacturers Certificate of Origin. I wanted a semi auto to start with for use at events and camping.
What I have done so far:
Drained the gas and used magnents to get the particles out. (It has a metal tank) I put an in-line filter on.
I prefer the looks of the high fender like the CT so I removed the low front fender and put a Honda fender on up high. It took a bit of modification to do this along with rubber spacers.
I changed the plug but the old one was fine. It was a Torch brand and not gapped correctly.
I drained the oil and checked for metallic particles with a light and magnent and found very few, just the normal fine particles that you would expect in a low mileage motor. The oil was very clean.
There is no rust on the bike itself but there are a couple of small surface rust spots starting on the exhaust at the head. Not surprised about that. The paint is ok..it is a bit heavy in a few places but no runs,raspberries or blemishes. The chrome is ok, it's not Honda quality, but it's ok.
I thought I would adjust the valves to get rid of the ticking sound and quickly found out why it was ticking...There was not a nut on the valve adjuster stem on the intake valve! When I removed the valve covers I could tell that there were no marks where this had been done before so I feel very confident that this came from the factory this way. I believe they forgot to put the nut on! Luckily this bike was purchased by someone who was very gentle with it and didn't use it much. The exhaust side was fine and set correctly. I also used a small magnent and light to see if a nut was inside the head and saw nothing. Hopefuly it's not rolling around in there! HA! Once I put a nut on and adjusted the intake valve the ticking stopped and it runs very quiet.
The carb is marked Mikuni Japan with 21 stamped on it...I don't know if the carb is a clone or not.HA! Like I mentioned when I first heard the bike run you could tell it needed adjusting and what I found was that the air box had way too much foam it it...along with the filter, it had two thick pieces of foam at each end. I took those out. The boot was also not tight to the carb and the intake was not tightened down to the gasket either. Once I did that and adjusted the air mix it runs great...I am pleased and surprised with it.
I have a long list of things I will be doing to it and if there is any interest I will post about it and what I find along the way. I don't want to bore anyone. Here are a few pics...Check out the bug decals... A dirt daubber with a helmet!! The last pic is of the front fender raised to CT70 height.
A few things other things that I have found so far. There were so many loose bolts it was unbelieveable. Now to be fair, the guy that had it had some serious family health issues with his child and did not spend much time with the bike so I am guessing that this was from the factory/dealer?? The other things that were nice surprises is that the throttle rolls back on it's own...Love that! The 12v lighting system rocks...It is such a huge difference between that and the 6v CT70's.
It does/did have this weird thing that when you use the blinkers a very loud horn from under the seat goes off and sounds like a back up horn on a school bus...Got rid of that.
