Today is Memorial day. A day to remember those who gave the ultimate sacrifice for their country and for those who came home but for one reason or another are no longer with us. For many of us vets, today is a very hard day. We honor those that we served with who are no longer with us.

Having served in both the Navy and the Army, I would like to first remember my brothers on eternal patrol. You don't know their names, but we remember the boats. USS Thresher, USS Scorpion, all the boats lost during WW2... Even those who were my adversaries have my respect and honor today. Kursk, Komsomolets... Too many to list.

Also today I honor the 8 brothers of the 724th En Bn that I have lost in the last 12 yrs since returning from Iraq. For some of you accident or illness visited you at home. For others the war never ended and your pains were too much to bear. I honor you most of all, and I look forward to seeing you again in the next life...

You all were taken away from us way too soon but you will never be forgotten.

Awesome! Congrats!

Sorry cyborg, that was one of the first things I did, put in a manual petcock. No vacuum petcock for me!

Bob, Isn't all you need is the master cylinder? Scrappy has one with the lever for $25.

Go to this page and scroll almost to the bottom Gy6 right master cylinder with lever

Here's a good one for ya. My scoot is an Icebear PMZ150-3C scooter (2 wheel) with the standard 150 GY6 clone engine.

Here's what happens. Sometimes, once it is fully warmed up, I'll be traveling at high speed (40-45 or higher) and it feels like an invisible hand starts applying the brakes, enough to slow me down 5-10 mph pretty quickly. If I slow down, it will return to normal running, but once it starts happening, any time I speed back up it'll do it again. The motor doesn't drop out, but the RPMs do decrease as I'm slowed. There is also no sound associated with this happening, no scraping, squealing, no change in the engine note.

The scoot runs great, pulls hard to 50~55, top speed about 60 on the flat @7500 RPM when this is not happening.

Things I've done to the scoot since it started happening, both to try to fix it and general upgrades:

Emissions delete
Hoca variator and 10G sliders
Gates belt
Yellow contra spring
Inspected clutch
58.5 BBK including new head and cam
New carb and intake/air filter with 38 pilot and 120 main
Manual petcock and larger fuel filter
Replaced all fuel and vac lines
Performance exhaust
Set, checked and rechecked valve gap .004 both
New tires
Inspected brakes front and rear
Several different CDIs I'm now running the Casoli from tvnacman (Thanks John!)
New coil and plug wire
NGK Iridium plug
New tires
Engine oil and gear lube checked and changed as needed

I thought I had it fixed this spring with the carb and BBK/head/cam install but it happened again last night after a long ride, as I was on a 45 mph road nearing home.

Could this be valve float? Hard to believe that problem would follow even after changing the head and cam.

I'm at my wits end here...

What does it sound like? Are the RPMs coming up the same way they did earlier or is the motor staying slow and slowly increasing in speed? When a motor "bogs" it has a distinctive "bogging" sound.

Could be a stuck weight in your variator if the RPMs do not rise quickly when you twist the throttle...

Have you checked the valves yet? Have you taken the variator off to make sure all the rollers are in place?
