Engine life of 70cc (China Bike)

[aqibabbas]

How much kilometers can a new china 70cc bike can give without any trouble?

[N0m1]

I rode UniQue UD70 35k kms with out any engine work when i had it.
I always changed engine oil N other things on time.

[mkkd]

My little bro did 45k+ still Ok. The only advice is to be use in single hand and max. 50kmh. Otherwise if you even opt Japanese brand it may malfunction.

Depends how you care and ride.

I have super-power sp-70 bought in feb 2007 till now it has done 50,000 km without a single prob.I change the oil on every 500 km.

@R1
I switch 1st gear on 0-20km/h, 2nd gear 20-35/40, 3rd gear 40-50 than 4th gear

@all
Now I make conclusion from ur comments that china 70cc bike can give average minimum +35,k mileage without any problem.

Why my bike gives a jerk while upshifting to 2nd gear from 1st gear ... it has only been run 2400 kms

[aqibabbas]

check ur clutch, possibly it is loose that's why u r feeling jerk during gear switching.

But it only happens while upshifting to 2nd gear all other gears are fine no jerk

my friend did 60k km on his hero before he had to do engine work,,and adter spending 4k and rebuild with chinese partsit was back o road like new performance wise,, and that may have done 20k more until now,,

mine dhoom did some 20k and engine is still ok though i replaced it with more powerdul 110cc,, stock cylinder piston are somewhat scuffed but most mechanics say its no problem ,,until then had no issue,,

[N0m1]

@Ahsan,Have U checked top speed?

[asjdsm]

ya,, its 100 at most,, but there is a lot of power even at 100,, avg is a stable 45-50 km/ltr,and mostly riding above 60 normally 75-80,,

my friend's father have unique 70, bought in 2005, done 60k+, clutch plates+mad-guards changed during this period...

[Sajid20]

Dear members, my friend use to ride my bike very roughly he is my good friend mana bhi nahi kar sakta usy, would it create problem for my bike engine?

[haroon_1]

recently overhauled my sohrab js70. 2005 model, driven about 78000 km without any problem, now its again new by changing head cylinder pressure and clutch plates and all other oem parts.

as log as he is using clutch to shif gears and is not over reving in firsttwo gears and not giving sudden bursts of throttle that is if throttle is given smoothly then it wont matter too much,,,

thanks bro but i didn't get your point which is bold above.

[asjdsm]

its not generally good to run with full acccelerator in first and second gear it quickly damages th engine,,
however u can run it full accelerator in 3rd and 4th gear,,,

Because ur 70cc bike has no power to give a jerk at high speed or in other words when the gear has more load on engine.
Either its ur clutch adjustment or u simply dont rev match while driving... leave race completely hold clutch and then put nxt gear, now give race again.. it shudnt jerk.
