Leaving her stock for now. Seems to run good for a 125 cc. Need to run her for a while.
Edit: Gonna regear to add some use out of first gear. Stock front is a 15 tooth, hope I can add two teeth but maybe just one.
What size is the fuel tank Barnone? My Lifan clone is 2.5 litre, which is a bit low TBH when you are out for the day on a run. I usually carry a fuel bottle with me with another half a litre in it, just in case I run out or find myself along way from a petrol station.
Returned home from holiday today to find my new front and rear sprockets waiting for me. Had a few hours out in the garage and fitted both, had to shorten the chain by one link as it was too long after fitting. Took the Lifan for a test run for a few miles to see how it runs. Initial thoughts are that it seems a good improvement, although acceleration is a litte slower. First gear is now useable at least, now doing 40 mph in 4th gear the engine feels a lot more relaxed and at ease. Will take her for a long run Sunday and see what I can get her up to.
The tank capacity is suppose to be 5.5 Liters which is about 1.5 US gallons which is close to what I put in the tank when it was empty.
I would be interested to hear the top speed. I can imagine with the smaller tank your needing to carry extra petrol. Will the gearing make much difference in that area? Improved mileage or worse (but better cruising speeds)?Quote:

Yes I managed to fit a 17 tooth front sprocket, I think I could squeeze a 18 tooth but don't think I will.Quote:

It sticks a an indicated 50 mph but I can feel the bike getting faster and it doesn't move. Previously it was reading about 5 mph faster than actual speed. Fuel economy was around the same as with the previous sprockets, but I was riding the bike faster than normal so think the sprocket change was negated by the extra speed. Were I to ride slower I could probably improve fuel economy.
my tyres are 3.50x10 too.
My front sprocket is 420 pitch with a 17mm shaft, its the same as the ST70 in the UK but not sure if its the same the CT70 in the U.S.
Thanks for the info. I will order a 17 tooth after I measure the output shaft which will hopefully by adding two teeth make first gear more usable.Quote:

So should be the same sprocket?
I am running a 31 tooth rear sprocket too. Any smaller and I think the hub needs to be machined down.
trexuk,
I counted the front and rear sprockets and came up with 15/32 which sure is different from your stock bike at 14/38.
I'd better go recheck my rear sprocket. Our bikes really differ in the stock sprockets. What am I missing? You must have really been geared low.
You were 14/38=2.71 ratio
Then 16/36=2.25
Now 17/31=1.82
Mine is 15/32= 2.13
Will be 17/32= 1.88
So we will end up about the same.
BTW: The Pitster Pro 125 manual is the same as mine.

And some parts are at

I have no way of knowing if mine was geared like it was as stock or if the previous owners changed the gearing? Mine is slightly different from yours being as its a 110cc.
I ordered the 17 tooth front and a 420 repair kit in case I need to add length to the chain.
I had to remove 1 link from mine when i fitted the sprockets. Thankfully my chain had a speedlink in it, so it was quite easy. I am going to order a new chain this week as the current one runs tight and slack when you revolve the rear wheel.
I wonder, and believe if true, the Skyteam 125cc uses a Loncin or Zongshen engine which would have slight differences from the 110 in the Lifan, as Trexuk has. I do remember American Lifan had the DAX replicas in 110cc form in the US (maybe Canada), until Honda sent them a cease and desist letter (I think they sent Redcat and a few others the same letter, too, back in the mid 2000's).
Put the 17 tooth sprocket (JT Sprocket JTF252.17 ) in place of the stock 15 on the CT70 clone and it really extends first gear. Took a ride to Deal's Gap to test her out. Did run her up to 50 MPH indicated for a short spurt. Still breaking her in.
Sprocket from http://www.amazon.com/dp/B001AVVXPY/...32200_TE_item#
Ordered two more for the monkey bikes.
Stopped at a place where two brothers on separate bikes where killed by a single auto running wide in a curve. I put up a cross last year and someone planted some flowers under it. Nice touch probably from a family member or friend.

I would be interested to read how the sprocket on the Ice Bear works out--I figure the other Skyteam will be similar to your Skyteam DAX clone.Quote:

Nice gesture on the cross part. I am amazed by how many crosses I see on trips from Yuma to Phoenix, or Yuma to San Diego!
Barnone: What size sprocket have you got on the rear?
Nice touch with the cross, sadly there are many of these road side memorials in the UK too. Thousands of people die each year on our roads.
32 tooth rear.Quote:

Where are the other CT70 clone owners? Should be some more on this site.
I'll report on the sprocket change for the hack and the Z50 clone in the other forum. Hope it works out at well at the change on the CT70 clone.Quote:

I drove over to Knoxville,TN via the Dragon in my Scion IQ the other day to hit Harbor Freight and then to visit the old bike get together at http://www.timewarpvmc.org/Tea_Room.htm. Great collection of older and newer bikes and their riders there.
Next time I go I'm gonna carry the hack in the back of my truck, park around the corner, and then ride up on the bike as if I rode from our cabin.
I used the GPS on my work phone the other night and it showed 47.5 mph as my maximum speed but I didn't have the throttle wide open, will give it another go at the weekend.
I am working on it! I would need to be able to hit about 55 mph and keep it for about 7 or 8 miles to justify getting one...Quote:

No way will my bike do a real 65 MPH with the stock gearing. Speedometer seems to be about 10% optimistic.
I added a speedometer and GPS app to my new cellphone and have ordered a handlebar mount so I can check the speedometer accuracy on the bike. Also I have one of the mini tachometers and a cylinder head temperature gauge (CHT) which I will install to get some numbers. Don't wanna see 420+ F CHT at wide open throttle.
Might do 65 MPH at red line with the + 2 teeth on the front sprocket. I will be happy with a 55 MPH cruise. Going to 4.00-10 tires will probably correct the optimistic speedometer.
Just checked mine again on the way home. It does:10 mph in 1st, 20mph in 2nd, 35mph in 3rd and 47mph in 4th so far.
I need a minimum of 55mph sustained for several miles if I was to switch off between bikes to commute to work on. Going to work in the morning, the several mile stretch is posted for 50 MPH with many of my fellow commuters wanting to do at least 70 or 80! Now that the agriculture season is starting up, there are many commuters who work the fields who cross the border heading in the opposite direction and the opposing traffic is one long continuous mass of cars meaning the Indy car hopefuls are riding a few feet from my rear tire because they cannot pass me. Pulling over is not an option because the shoulder is half broken asphalt and desert sand meaning pulling over at speed is dangerous. At least at 55 MPH, I am doing a few over the limit.Quote:

Had a fool in a Land rover do this last weekend as I was overtaking a cyclist, he missed me by about 6 inches. 2 minutes down the road I caught up and over took him while he sat in a queue of traffic. They seem oblivious to what they do.
Here in the mountains of Western North Carolina there is little traffic and the local drivers tend to be courteous. A 45 MPH cruise is sufficient.
Not so in Southwest Florida where the winter season traffic is like the Indy 500 drivers that culcune experiences in AZ. Not only can drivers not see their speedometers they must be color blind as they can't see the red light on the stop light.
