Loncin 200cc

[Brent95]

Hello,

i've been working on a 200CC loncin motorcycle.
Now i got several issues.

1. Carburator issue
The carburator seems not to function since i rejetted it a few times and it doesn't run properly, it only runs when i close the 'choke' so less air gets in, so i assume i need a bigger jet?

2. Engine ticking
So the engine is making a 'ticking' noise, it sounds like something in there is loose, but that is almost inpossible since the engine was worn so i replaced the whole cilinder + piston & sigments.
Or the sprockets inside may be worn?

3. Smoking like a Moth3rf4ck3r
It seems to smoke a shitload of grey smoke, i replaced the cilinder & pistons since that was worn out, but after a new cilinder kit it stills smokes alot .
Any idea's where this can come from?

Some pics (may be helpfull).

Oil seal gone letting oil get into the topend and burning it?

Looks like there is oil on top of the piston in the first picture
