Any more info on this chinese motorcycle?  By  prodigit (Read 39,579 times)

I really liked this bike when you started this thread but seems like its not working out to well.

Did you ever get it to run without the choke partially on?

Alright guys, more data came in!

I gave Rebelgears the dimensions, and they will soon add this motorcycle sprocket to their arsenal, thanks to the dimensions I provided them.

Here's my data on the sprockets:
- Mechanically a 30T to 46T should fit the bike
- Preferably you will not want to go below 35T, nor above 38T, as that is your sweet spot.

36T is the optimal sprocket; which I would suggest you, for a single rider ~170LBS; because:
1- The sprocket can be installed without having to cut, and re-attach the chain
2- You can reach the bike's top speed with this sprocket
3- You still have good acceleration in 4th gear, while gearshifts from a standstill feel A LOT nicer!!!!
4- Cornering in 4th gear (~20MPH) is possible, so no downshifts necessary.


For the 34T sprocket:
34T top speed equals 40T top speed (~60MPH on dash, both in 3rd and 4th gear with the 34T).

Because I care more about MPGs, and I installed the 34T, and had to shorten the chain, and will not be installing the 36T.
If you weigh more than 200LBS, and ride in hilly terrain, I might suggest going to Rebel Gears, and get a 37T or 38T. Prices are ~$60 tax incl.

I am willing to sell my stock sprocket, as well as my 36T, for $30 each, $50 for both; shipped to anywhere in USA.

PM me if you're interested.

Again, if you're more than 200LBS, or ride with 2, or ride on hilly terrain, I would not recommend the 36T but a larger one.


The motorcycle, stock with
~10W40 does ~.5MPG
~10W30 does ~86.5MPG
So in other words, expect it to do 85MPG stock.
With the 34T after calculations, I should get -100MPG
With the 36T you should be able to get -95MPG.



My experience with the 34T sprocket:

Easy to install, however linking the chain back together without proper tools is difficult.
Make sure you grease the rear wheel axis rod, and the chain, and adjust the rear brake, as well as correctly tension the chain!

Using the 34T, I noticed a significant reduction in vibration, a much smoother ride, MUCH better (longer) gear shifts; rides almost like a big bike, with the exception of final gear low acceleration, but it's easy to downshift to 3rd gear for better acceleration!

Shifting to 4th gear with 34T happens at ~30MPH on the speedo;

cornering at 20MPH in 4th gear is difficult. Engine goes into low RPM, and U-turns is necessary to downshift.
With a 36T it might be possible to do U-turns and corners in 4th gear.


Also,
10W30 oil is NOT recommended for hot FL. I've noticed that the clutch occasionally slips. 10W40 IS the recommended oil for this bike, like the usermanual says.
10W40 is a bit on the thick side for the engine, but is about the thinnest I'd equip the clutch with.
If you live in colder regions with weather below 80 degrees, 10W30 might work better for you, but in S-Florida's + degrees weather, 10W40 is recommended

[replyingto=averageguy]averageguy[/replyingto]I could add also that my engine "tick" is less pronounced when the engine is cold and becomes more pronounced as the engine heats up. It also "coughs" once in a while not very noticeable but I can hear it now and then.

The chinese speedometer is actually 5MPH overrated across the board.
I measured the green speeds with a GPS.
The orange speeds are deducted from the green speeds

The red speeds that I added are approximations deducted from the orange ones, and may be off.




As you can see the MPG speed rating on the speedometer pretty much is 5MPH overrated across the board.
40MPH is when the needle is straight up (actually 41MPH, but who cares...)

That's the sidepeg stand kill switch. It stopped working on mine after a few rides.
You mount it to the back of the sidepeg with a screw.

You'll notice, when you rotate the metal center pin, that your bike won't start.
The only thing it does is shut down your bike when you lower the side stand. in my opinion pretty useless (annoying even), like sometimes you will want to put your bike in the garage and need to get off it, to open the door, the bike shuts down.

It just uses a small bolt that goes into the center, right into the back of the sidestand peg.
