LEI 125cc Lifan vs Predator 140cc Lifan

[craig89]

I've been riding street bikes for a while and plan on buying a minibike, from all the forums i've been reading people seem to be saying lifan engines are the better than the other chinese engines. just wondering what the other key things to look for on a minibike are?
was looking at buying one off ebay either a
140CC ALLOY PREDATOR PIT DIRT BIKE MOTOR THUMPSTAR PR4
or a
2007 LEI XR 125CC THUMPSTAR LIFAN MOTOR TRAIL DIRT BIKE
are either any good or just ebay crap that will fall apart after one ride?
any other suggestions?
Cheers

hey mate i just bought one of those LEI bikes the other day, i havent got it yet but if you want a lei, get the model with usd forks etc...not much more expensive and the xr model looks like a peice of sh1t anyway...dunno about the predator tho...hope this helps..

I bought the Lei XR125cc last wk. Put about 3 tank fulls of petrol through it so far. No problems yet. Mine had a few bent bits and a couple of screws where stuffed.
I have never ridden any other pitbike but they seem to go pretty good. I karted my gf and I (combined weight of around 100kg) up some pretty big hills without much problems.
I did notice that it jumped out of second into neutral on one occasion.
Only thing I rly did to it was lock tight all the bolts and oiled up the front and rear suspension bushes, they where dry and squeaking.
The other thing I will do when my new 12" front wheel arrives is replace all 4 wheel bearings with new ones.... my last pocketbike broke these within a couple of wks.
All I seem to be doing now is bidding on performance upgrades on ebay lol

Hope this helps

I swear i typed a long response to this! wtf!

Anyways....

Ill try again

I bought one of these Lei XR a wk ago. Have ran about 3 tanks of fuel through it and it has been fine. I did have to lock tight all the bolts and oil the suspension bushes because they where squeaking.
A few of the bolts needed replacing because of the dodgey chinese metal. It goes pretty good, although I cant compare as I have not ridden any other chinese mini dirt bike.
No doubt it will have plenty of problems along the way, but I dont mind tinkering.. part of the enjoyment in a way.

I just goto change all the bearings to good ones as they stuff up pretty early on... well at least on my last pocketbike they did

hope this helps

I am a mechanic in a bike shop and i see lots of stuffed Lifan 140 motors if they are started "CORRECTLY" they are ok. But if people try starting this motor in a normal way that you would start most pitbike motors you could have a problem. I have seen lots of Lifan 140 motor stuff. Broken kick starter gear. Then the broken teeth get jammed in the gears most of the time and break crankcases THIS IS NOT GOOD. Then get the motor and drop it in the bin not worth fixing. Buy YX 140 motor that Motovert & 08 Pitpro's use and happy riding. Lifan 125 & 110 are great just always keep your air filter clean and well oiled and engine oil clean on all motors.
