Hey guys really need help with this one i got a zb 50 that im rebuilding and a got every together except the motor. Does anyone have any jialing, lifian, or zohnsten 125 or 150 they want to selll? But im open for ideas so if anyone is selling a big bore kit or a 4 spd upgrade that will work on a zb engine in interested.

Thanks

stay away from the 150 motors with the klx head like the gpx or ogm because it will hit the stock front wheel. i found out the hard way. the new lifan 150 with the crf head seem like it might work.

What is your motor budget? I would keep that ZB all Honda because of how rare it is.The bike is worth more with the original engine in it.

Tmas, thanks for replying, but see im only seventeen and i got this bike for fifty bucks from some guy and i completely ripped it apart had everything powder coated and im putting it back together one paycheck at a time so as far as my budget goes probably looking to spend not much more the a couple hundred on the motor, ide like to do up the ZB motor, but it looks like its gonna be much more expensive then just slapping in a bigger pit bike motor. But im really not sure where i can get the most bang for my buck so im open for any suggestions.

tmas is right about keeping the stock motor if you already have all of the parts for the motor. if you have a lot of the parts missing from the stock motor like i do. i just got a gpx to get me down the road and box the stock one up to rebuild later. but, if you have most of the motor and it is in good shape then go with it. you can always add power to it later on if needed.

my zb motor runs and all it just has no power

88cc Big Bore kit keeping the stock head. You'll rejet the stock carb.

The ZB50 takes the same top end engine parts as the Honda CRF50.

I will sell you a takegawa 88cc ftp kit for a good price if you want to go in that direction. The xr70 carb and intake manifold are almost identical to the zb50 ones, except the zb50 carb is only 13mm. The rest of the engine is basically an xr50 motor.

tmas

They are all like that in stock form. 2.6 HP. Get what Z recommended.

A TRX90 or CRF70 head to go with that 88 kit adds some oats, and keeps it more Honda.

if ur gunna get a bore kit and dont feel like spending over 500$ look into the trailbikes bore kits! im running an 88cc and it never gave me a problem "besides timing" but thats easy to tune!

So how much more power am i looking at with an 88cc bore kit?

s_10onbagz

My 85cc w/ xr70 head, carb, exhaust, and 4 speed does 55-56mph on flat ground but I'm not sure of power. The bike is pretty heavy too.

tmas

Most 88cc kits produce 7-8 HP stock ZB motor is 2.6 HP.

Sounds good how much do u want for it?

ksteder

Ya thats pretty much all the power im looking for, especially because im keeping the suspension and brakes stock.

Yes it will, the ZB is a 12 volt cdi motor like the crf and xr.
