There is a 2013 PRB 100cc bike with 6.7kms on it for sale locally just wondering how they are?

I have a ZB also.

I've heard of a PBR 125 (Skytean Chinese ZB clone) but never a PRB 100.

Could very well be a typo

Picked up the bike last night!
Owner said it hadn't ran in three years so he had a mechanic look at it and said one jet was plugged and he was going to order a new one. He also said it ran but wouldn't idle good. I picked it up as is.

Well I tore into this morning cleaned the carb and dirty jet is now clean. Battery was stone dead so I put in a spare I had and cranked it over but it won't start!

No spark at all. I switched CDI boxes and nothing switched the coil still nothing. A different spark plug nothing. Cleaned the ground contacts on the frame still nothing.

I hate chasing electrical problems like this at a loss right now. 20190703_210351.jpg

Just a thought...
have a look for a 10 amp fuse close to the battery and make sure it's ok.is there a switch by the kickstand?
tmas
I did check the fuse with my meter and it’s ok and yes there is a switch on the stand! I’m hoping it’s something obvious I’m missing.

Try disconnecting the side stand switch and see if you have spark. I found an Skyteam manual. The wiring diagram is on page #37. Make sure your spark plug boot has a good connection to the wire. Check the neutral switch too.

Disconnected the side stand switch and I have spark!!!

Managed to get it running although poorly, excessively rich. Float height may be out or something I have a similar sheng-wey carb I will try.
This thing has lots of vacuum lines every where for smog would like to remove.

Thanks tmas.

The stock exhaust has a catalytic converter that will give you all kinds of issues. You can replace in with a honda monkey down pipe and it will really make it breathe.There's also an egr on the bottom of the head that can be removed, or if you really want more performance you can replace the head with a big valve head. The carburetor is some epa approved junk and should be replaced with a 26mm carb

It would barely run with the stock carb so rich it was choking out. Had a new carb that was similar but I had no fuel?

Trying a 22mm carb I had on a running bike not too long ago hopefully it will run ok!

I pulled the canister and most of the vacuum lines off already.

If I like the bike I was thinking big bore and gig valve head but I don’t want to sink a lot of money in right now.

Any recommendations on a bbk and head?
