The omega/accralite piston and worries about oil consumption..

It seems to have a different japan-style mounting on the tank..
I think i have the carburation now close to okay and with the 19T sprocket i dare to cruise 100km/h. Accelleration in 4th seems okay? But maybe i unwilling comapre irt with teh diesel
From the higfhway it is indeed a lot of changing between 3 and 4.

If you tell me 18T is better, i shouldn't be pigheaded and will do so..

For information, I just fitted a pingel tap designed for a Harley Davidson using a 1/4NPT to 1/4BSPT adapter (which had to be drilled out a little to fit). After a bit of a hiccough in which I tore the in-tank filter and had to solder up a new one, I've got it fitted. These taps are expensive. This one was £70 second hand, they are around twice that new.

I just put 4.5 litres of fuel into the tank then timed it emptying back into the can through the tap (including the reserve setting). It took 3m 10s. That makes a flow rate of 1.4 litres per minute!

From top of dipstick to the lowest point, just on the 'min' in 600km, after i replaced the forementioned oil seal and installed it the right way...

It can't be 2,25 Litres from top to lower mark of the dipstick? I really hope??

Wotcha.

I've had an Accralite piston in my Bullet since 2007.
I've got one of the early Italian alloy barrels and the piston rattles about like a marble in a tin can.

On the plus side, I know it ain't going to seize. Oil consumption is just the same as it was with the normal piston.

This piston was purchased from our host this year. I understood it was better then the original?
What is the oil consumption with the original piston?

After 2500km the piston rings should have bed-in.
Also the valves and valve guides were renewed.

No valve stem seals were present and not installed by me. (should i maybe?)

Oil consumption is more then 1 litre on 600km.

No excessive smoke, engine performs well, spark plug is heavily fould and needed replacement.
