hello fellow scooters,
i just purchased a UM 150 II scooter for gas purposes. i have to take a course to ride on the military post, but i have been riding around town ever since i got it. my question is this...i can only get it up to 50 mph, 55 if i lean over, does anyone know how to adjust the throttle so i can at least get it to 55mph? i love this scooter and i do get respect from the guys on their hogs. i forgot to ask if anyone knows of a windshield that fits this scooter. thanks a bunch

Hi, I have a line on a gently used Matrix 150, 2006. Do you like yours? Do you feel like it is well made? How does it perform (aside from the speed issues)?

Thanks.

I like my um scooter and would love to know if there is a windshield too. I am a big guy and mine gets up to 60 to 62 mph. I don't know of any throttle adjustments you can make.

Read the break in procedure in your owners manual!!! After the scooters are broken in they get faster, you shouldn't be running it wot yet.

Read the owners manual about break in procedure!! Scooters get faster as the engine gets looser but for the first few hundred miles you shouldn't run it wide open. look in CBXman for a windshield.

Hi All, me too,

I'm also wondering how to get more performance (speed) from my United Motors Matrix II-150: it seems to have a governor at 51 mph, even if I tuck down there is no difference. Is there any reason I can't change to full synthetic oils in the crankcase and gearbox? MY choice would be RedLine oils. It seems to me the engine/gearbox would mechanically last forever and I might get 1 more MPH and perhaps a little better mileage (now around 85 mpg). Also, as Bama said a windshield would be nice to have here in Seattle.

Help! Where do I get parts?

I bought it used for a good price because it's rear brake master cylinder packed up ... and let me tell all, riding in the Seattle rain this summer with only a front brake has been spooky.

I Googled United Motors and my scooter appears to be a 'badge-engineered' VENTO and also a ROKETA TAHITI 150 --- and there are literally dozens, perhaps hundreds of complaints about the Roketa version. My UM has been absolutely dependible for the 500+ miles I have riden it ... except for the rear brake issue.

Thanks in advance, Jim In Seattle

PS I found a 'Cousin' scooter today within 2 miles of me, but it has almost no identification on it except for a VIN plate. It was made by "Unique Industrial & Trading Company for Goldenvale Incorporated" ... No question that aside from a few cosmetic differences it is the same machine. I Googled that name and hit the jackpot regarding 'badge-engineered' scooters. I have yet to follow up on the names: Powermax, Plazela, Concept A1, X Speed, Runniest, Boss, Arrow, Falcon, Movicity, llborro, and Ovni.
