In this thread, we will explain how to time our engines with simple steps.
If we remove the time cover, as you can see, there 6 big gears and a small one:
1. Exhaust cam shaft gear
2. Intake cam shaft gear
3. Non work gear
4. Non work gear
5. Ignition gear
6. Crankshaft gear
As you can see in the photo, the N.1 N.2 and N.6 gears are marked with dots.
**
In case you can't see the dot in N.6 gear, you have to remove the nut,
but be careful because this nut is clockwise. After that you will see
the dot. Then tighten up this with 9.2 kg torque **
Step 1 : Bring the odd dots from N.1 and N.2 dot gears, face to face.
Step 2 : Bring the double dot from N.1 gear face with the dot from N.6 gear.
P.S.1 After that, use only the gasket for timing cover but no gasket glue
after a problem with a broken oil pump (feed) http://homoratus.blogspot.gr/2012/08/engine-problem-bad-news.html
, i had to open my bullet's engine. So i try to decoke its aluminum and
full of carbon cylinder head. We must use only mechanical ways to clean
it (no chemical) just gasoline and nothing more.
At start, i had
a problem with the cylinder head of the engine. I could not remove, so i
tried an "old fashion" way. I heated it with full of attention. At the
end, the head was removed with success.
As you can see, there are many of carbon remains
The tools i used were a paintbrush, some wire brushes, electric drill with a wire brush tool and a metal tweezer.
Take a bowl with gasoline and put the items there. Take the paintbrush
and a sand paper and remove the carbon as best as you can. Then try with
the electric drill with the wirebrush tool. Please be gentle because
the valves are from steel but the the cylinder head from aluminum, so
you don't want to hollow out or trench your cylinder head. You will
repeat the same way for your piston too (try with a cloth with gasoline
to remove the remains from the piston rings).
I have to say that i polished the piston with a brush that i use for
aluminum with the electric drill, but don't forget to clean carefully
the piston with gasoline after that.
