Smokes a bit when decellerating, grey-ish smoke, have to fix that.

Put new valve seals (OEM) and new piston rings on it.. Not happy with this

I'm no specialist on exhaust smoke but if it was burning oil on the over run it should / usually is blue. A grey smoke I think is a lean condition but don't quote me - ideally you want no smoke whatsoever LOL!

Lean? I thought too rich...

But I need to ride behind it to have a proper look. I have to ask my mate to go for a ride..

 

I don't like smoke either, no matter what color

I finally found an affordable TD04 turbo, good condition for $150, 25km from where I live.

I started the modifications already.

The TD04 is quite a bit bigger then the VF20

I've got the bike going again!!

Turned out that the expanders from the oil rings were the culprits, smoking is solved, no leaks.

The TD04 turbo is installed, carburfuckingettors are adjusted/tuned.

 

There's a difference with the turbo's I must say..

Sounds like a Lancaster bomber at idle, what it must sound like at full chat must be unbelievable

Little update;

 

Been riding with the TD04 for a while now, I like it. Doesn't kick in as hard as the VF20, but goes alright, weird combination of first a bit gentle (lag) and then it's all there..

The TD04 does a way better job at higher rpm.

For the TD04 are reconditioning sets available, so you can do it yourself! Not too hard, set cost about 150AUD.

 

Bike was at an annoying rev range when riding around 100km/h. Therefore I put a bigger (1 tooth) front sprocket on it, this did the trick.

Now doing 100km/h at about 3700rpm.

But, there is a side effect I didn't think of, it accelerates way harder/faster now! The other thing it also does now, it lifts it's front wheel way too easy, the first couple of times it's fun, but I don't feel it coming, but ''too much'' throttle and it comes up, also it 4th gear. 

And with the police being that strict here, and quite a few unmarked police cars it's not that fun..

Usually acceleration is slower with a larger front sprocket. 
Must be Australia....

Generally yes, but the extra gearing loads the turbo making it work harder. Take a std geared gsxr, add a decent turbo and it'll easy take 3 or 4 teeth on the front and accelerate just like std.

Depends how hard the engine has to work
