45!
My Znen has a 38 and 118, 1" header shorty muffler, and a pod filter.
a BBK, big valve head and an A9 (?) cam seems like a good start.
IF I found someone fairly close, I could see getting the case bored for a larger BBK. Jim is on the kitty-corner of the state from me.

If it is empty, or full, you wont see a level. If it is frosted and opaque, you cant tell. Proper level is topped up but not overflowing. The top of the sight glass is the low level. When you begin to see a bubble or the fluid moving, it is time to top off or replace.
To take the lid off - find a good clean Philips screwdriver that fits perfectly. The small screws tend to round out because they are different metal than the reservoir is made of plus the brake fluid = galvanic reaction and basically seizes the screws. Use downward pressure, even a couple taps with a hammer to help loosen the screw. Slow and steady torque to turn the screw out.
Take the lid off and see if there is or is not good fluid. Depending on the age of the scooter, you may have the original fluid, or over 2 years old fluid and it need to be replaced with new fluid.
I have disk brakes front and rear, so I have two master cylinders.
Scooters with rear drum brakes have no master cylinder on the left handlebar. The cable needs occasional lube, but no fluid level.

I'm past 6500, Benn running a 110 jet and two spacers for the needle. Seems like a lot of carbon in the combustion chamber if you might be on the lean side, but maybe that explains the exhaust valve is so white.
I was going to use a uni, but switched to a pod when I did the EFI conversion. I used the original filter and housing until I started the EFI.
I should see if my USB Endoscope will have a peak in through the spark plug hole.
I wish the upgrade parts were cheaper and easier to get, for the B motor.

It is in a neighborhood, like a street party. Cops threaten each time to shut the whole thing down.
I understand lots of hooligan-ism happens down at the Harley Museum before they ride up to the Rockerbox area.
Groups of bikes and scooters gather at different places and ride in.

I have used the kick start in the past, but I don't even check it. I had it apart and put it together misaligned, then corrected it. (I think). I've used it once in an emergency - both brake switches had gone bad in short order.
I made the spacers and support for my new muffler. Didn't need to weld. Besides my swing arm is aluminum.
OTOH, I did have to weld the engine case on my Znen in order to make a repair and reinstall the new exhaust and the swing arm. You should be able to see those pics in my photobucket if you go up a level or two and see the Znen folder.
A VOG 260 is a bit larger than a 150.

I'm really curious about this. I can't search the board for "LED" because it's not a 4-letter word  The lack of short word search is annoying. Look for GAS or OIL or LED... Try searching from google and the itistheride.boards.net url. |

I think thick leather pants to keep from getting pinched, Unless you'd like to get your seat area pinched on every bump.

a sight glass is nice - you can see a low level before you run out of fluid in case of a line leak. Maybe see a deteriorated fluid color if you can see through the "glass".
A separate translucent reservoir would be nice, but then your at replacing the master cylinder in order to go that way.

Now between two scooters with front and rear disk brakes, I have replaced 3 sight glass. The original plastic does not get along with the brake fluid. I replaced the broken down plastic with watch crystal. 16mm X 1.0mm I used RTV Black. First one on Xingyue front brake master was in July 2010. It was opaque tan, and I touched it and it crumbled. Ordered 4 crystals. www.esslinger.com/watch-glass-round-flat-mineral-glass-crystals-1mm-thick.aspx I looked at kits or services to do the repair. Most sites were old and defunct, or cost more than the price of a new brake system with master, lines, hose and caliper together. Still looks crystal clear today. Second one was on the Znen rear brake master when I pressurized the reservoir by moving the pistons back into the caliper without removing the lid. Same size crystal, more RTV Black - with more than 20 hours cure time before adding brake fluid and bleeding. Third one was the rear brake on the Xingyue. I was looking at -NOT TOUCHING- and it appeared to be bulged or bloated. I took the lid off and it started leaking. For sure that fluid was due to be replaced anyhow. Cleaned the hole, more RTV Black and another new crystal. Curing for another 20+ hours. No doubt I will bleed both front and rear with all new fluids tonight. The front brake master on the Znen still looks good, and that fluid is only 1 year old. |

Congratulations. Glad you got it all back together and running.
How many miles on it when you pulled the motor?
What are you running in the carb for jets?
Bluefront had the same problem with a new head. He slotted out the flange holes, and used a thick washer or something to span the gap and hold the exhaust tight.
I do wonder about that white valve. I do not recall ever seeing one like that on any vehicles I've ever worked on.

As always, be sure to adjust the valves.
