Well where do I start I bought a crf50 motor with a takegawa 88 kit but it has a knock in the bottom end so I started to pull it down to find out what is wrong with it and I think I found it.

It looked like it hadn't been cleaned in a long time because it took a lot of cleaning to get the dirt off

When pulling the flywheel off I found a bit of metal on the magnet

Also found out it had a hd clutch and high volume oil pump

Gave the manifold a glean up and paint stripped the ugly blue paint off it
 
Some coin has been thrown at that motor
Are you heading to the sinister race in January ?

Yeah I'm going to the sinister days I can't wait for it
Also the only thing I can find wrong is the con rod bearing is worn out
 
Yeah that will give it a knocking sound , they rarely let go , bit of bad luck there
I've got a spare crank I think if you want it I can have a look

Thanks I'm going to try and get the bearing pressed off tomorrow so I can order the bearing then it will be back up and running if it still knocks I'll let you know

Bought so new tappet cover and gave the rocker cover a nice coat of paint
 
There is a complete bbr primmy on pm for 2.2k , it's immaculate , maybe see if he will part it , it's so cheap
 
Yeah I've seen that it's clean as but i don't really want a bbr primmy and I also don't have the cash I've got to sell some parts on my stocker first
