WPB 140 Rebuild With added Supermoto Fun

[alexdavies3]

Hiya lads im new to the forum and recently purchased a Wpb 140 it has the yx engine the bike was a heap when i got it. There was oil leaking out of everywhere and the oil cooler bracket itself had snapped causing the cooler to rub on the front mudguard and also the bike was incredibly dirty.

Here is the bike when i first picked it up all beneath all the dirt the frame is solid.

Next i removed all the plastics to clean them.

Before

After

Plastics all clean and polished.

The bike back together after its clean.

Next i stripped and cleaned the carb whitch was very dirty.

Then i decided to pull the engine out of the bike which led to me dicovering this mess


So then the engine came out.

I then decided to spray my spare set of plastics white to see what they looked like i was very impressed.




and a photo of the sized difference between my two race bikes.
Any advice on upgrades would be great thanks.
Cheers
Alex

Where is it leaking? I;ve seen oil cooler head bolts fitted without copper washers that leak badly. cheap and easy fix though.

Not too expensive to replace the oil lines.
