Lol I thought carbs where supposed to be better power/sound and injection just spread the power out across the rev range and gave you better fuel economy?
Anyhow got it apart and here's what I found...
Bit of water that had pooled and gone a bit rusty inside the cylinder 4 intake on the bike carb manifold...
I then got the whole manifold off and got a bit of oil leaking out head from where the channel comes down from the rocker area but no water (I'm guessing this is normal?). I also stuck my finger down the intake ports and only cyclinder 4 was wet. The water outlet behind port 4 at the back of the head was also strangely dry disproving my theory about water leaking out of here and down the intake 4??
The oil does seem to have spread/leaked across the bike carb manifold gasket although there was no signs of leakage out of the manifold
