geh3333, Are you feeling better?

Did you find a new fan shroud, or are you going to try and fix it?

I do fill the fuel tank to the top. the fuel tank is small, only about 1.45 gallons.
It could be that the traces of oil was from before the rebuild. i'll keep and check it.


I finished doing the break in today (600 miles) , so i worked on the scooter today.

I changed the engine oil, and also the gear oil.
Rearding the gear oil, it was really dark color (almost black).
I never had this kind of color with the gear oil.
The only thing i can think that cause it, is that some of the new bearings still had some grease in them.
That because some of the bearings came with side covers, and i removed them, but they had grease inside,
and i cleaned as much as i can, but some grease was still inside them.
Can a grease cause the gear oil to get a black color?

I planned on replacing the fuel filter, and when i dissconnected one of the fuel lines, fuel started to flow out.
This means the fuel petcock is not good.
I started to drain the fuel to a bottle, and when the fuel level got to
about a half of tank, suddenly the fuel petcock started to work again. What about that?
Maybe too much fuel inside the tank can cause the petcock to stop working?
Anyway, i'm going to order a new one, and mean while i will not fill more than half of tank.

Do you think the bad fuel petcock is related to the fuel smell
i sometimes get from the exhaust, when i'm standing with the scooter and the engine is idle?

I also checked the valve clearence, and the intake was ok,
but the exhaust valve was slightly too open, so i adjusted that.

Thank you guys for helping.

I read your post about hitting that deer. I'm glad to hear that you are ok and well.
I hope you'll be riding again soon.

The scooter is not smoking or bogging, but i did notice that sometimes when i'm standing with the scooter and engine is on,
the exhaust gas smell like fuel.
I checked the fuel consumption a few times, but i need to drive it more to be more accurate.
i used the scooter with a lot of stop and go, so i got a figure of around 63 MPG.
Without so many stop and go, i think i can get around 75-77 MPG.
This is about the same fuel consumption i had before the rebuild. Do you think it will get better? (i only done around 400 miles)

I have a CV carburetor with i think a main jet and 35 pilot jet. (These are the stock jets).

Regarding the oil consumption, it's no longer drink oil like it did.
Before the rebuild it got to a point where the oil consumption was almost 1 quart for every 620 miles. (strangely it didn't smoke).
After the rebuild it burned a very small amount of oil at the beginning, but now the oil level is constant, and it's still
almost at the top level (i didn't add more oil since i first started it).
I understand that it's nomral for a new engine to burn a small amount of oil at the beginning.

Thank you JoeyBee.
Your plug looks perfect.

If you have a richer mixture, can it prevent from the threads to have these burn marks?

I hope that these bolts will not get loose.

I took pictures of the plug, now that i did around 500KM (310 miles).
What do you think about the color of the plug?

I had to use a heat gun to warm the bearings seat so i can get them out with the puller.
When i installed the new bearings i also used the heat gun to heat the bearing seat, and i put the bearings in the freezer for a few hours.
Still, they didn't go in so easy like you see in this video.
Only the final axle bearing dropped straight in, and also the driving gear (with the bearing on it) just slid in without any force (after it was in the freezer also).

The small bearings (number 6301C3 i think), were a tight fit,
and even after heating the bearings seat, and putting the bearings in the freezer,
i still had to use a socket which have about the same outer diameter and use a hammer to get them inside.
To replace the bearing on the driving gear, i asked someone with a manual press to help me with that.
