I have a broken stud. I haven't taken the pipe off to see if there's a clean break or some sticking out so I could grab. It's my project for next week. If I fail to get it out or screw up drilling it out, I will neede a new manifold. I have a velocity 150 bought at scooter depot. When ordering the manifold, how can I tell what brand motor I have? Where's the best place to order from? Is this a job I can do?

Uhm....it's a new head, not manifold. On the engine where the center stand bumps up against there should be a stamp saying 157qmj or something. Maybe 157pqmj. But first, try to get that rascal out of there.

Sorry about the nomenclature mix up. I'm in the process of looking for reverse drill bits and a easyout set. Thanks for the info.

I don't have a very good track record with those easy out drill type bolt extractors. If there's anything left try maybe some vice grips or an actual stud remover.

Short of pulling the motor to access the bottom of the head, you can remove your mirrors, tape some foam packing material around the handlebars, and over the seat. Drain the oil and gas.
Flip the scooter upside down. Wrapping a movers blanket around the body can help protect it from scratches.
I haven't flipped my own, yet, but I have an exhaust to modify to fit this spring.
I have heard this mentioned on other scooter forums and several motorcycle forums, too.

I do not think flipping the scoot upside down is a good idea, you have to many liquids to think about GAS, TRANNY OIL, CRANKCASE, BATTERY ACID, If liquid cooled antifreeze etc.. To much just to try and get a stud out of the head . If you have an extra pair of hands raise the front wheel up on a block a bucket anything really so you have some room to work underneath while the extra pair of hands holds it straight. Or you can set up some hooks inside your garage and strap each handlebar to the hooks just as you would on a carrier.
You can get at the head pretty good from underneath just take the bottom pan out.

the stud has a non threaded part in the middle i've broke them before it usually breaks off leaving the non thread part exposed that you can grab with some vice grips or pliers.

Oh and if you can't get to it from underneath take off the head. Been there done this.  |

The battery also slipped my mind. Take that out, unless its a gel, then no worries.
The gear oil could be an issue, possibly a slow drip. Maybe duct tape a rag over the vent. Or just drain it and refill after , its probably due for a change anyhow.
A liquid cooled system should be leak free - besides any overflow tank. Extra hands are nice, but non-existant for me.
Just like flipping a bike onto the seat and handlebars, loads more access, and I know laying on the ground for long periods to fiddle with stuff is not so much fun. Clutch , tranny, exhaust, oil pan/oil pump, drive shaft... It all starts out like fun and games but by the time your done, your neck and back are feeling it.
With a high enough list to stand or sit and not be awkward, then I wouldn't think about flipping it.
Laying a two wheeler on its side, preferably table height would also work.
But scooter plastics are fragile so a 180° flip increases the access with less risk to the fenders.
I have also thought about a block and tackle inside the garage, I'm sure the rafters will hold fine.

IDK about turning that thing upside down like a bicycle...however, laying on its side carefully with some blanket or pillows might work ok. Check if you can get it with vice grips or something before you get to that point.

I had this happen and just laid the scooter on its side to do the work. Saw a video of a scooter mechanic in India working on one like that so thought I'd give it a try. Just make sure there isn't much gas in the tank and let it sit upright for awhile to allow the oil to flow back into crankcase.
