RFZ140 Owners manual?

[Ben J.]

I picked up a cheap rfz140 that barely runs and I need a bit of info to fix it up

Usually on my Japanese bikes I just download a PDF manual and it's got everything like oil specs and torque for each bolt but I can't find anything for this bike

it's got Apollo and Elstar branding on it and it says rfz140 but I've checked both websites and they don't seem to have anything for it so I came here to see if anyone's got oen they'd be willing to share

It's hard to say, but the engine could be a YX140.

If so, then there will be a lot of information. 

In fact, chances are pretty good that it may be either a YX140 or a Lifan140.

On the side of the motor will be a number.  Usually, the number is found below the gear shifter. It's a motor "Family" number.

Post that up, and it will be easier to identify what motor you have.

Yeah it's a YX140 engine with a Mikuni carb

Here's a breakdown of the YX140 on Tbolt's website
