This isn't a frame up build, but I just wanted to make a thread for all of my questions pertaining to this individual scooter. This just seemed like the right place for it.My pop just picked this up for $200 in Richmond. The guy said that it wouldn't start because it wasn't getting gas through the carb, and that the battery was dead. I don't know if I believe that, after seeing what I saw when my dad brought it home. You'll see. Too bad he forgot the key! I would love to see if it cranks over. The guy is mailing it to us. Until then, I will have to fix other issues.     This is what I was talking about when I said I dunno if I believe him about the gas through the carb. He cut open the filter box (I believe?) and now the filter is exposed. I'm thinking that we could have a blown up engine from running too lean. We'll see when I get that far.  Then there a couple of hoses hanging down. I haven't tried to figure out what they go to, just don't have it in me right now. Been working on the Popcorn since 10 this morning.  And the next problem would be the steering column. It's loose, from front to back. When you brake, you can feel the whole thing move. I dunno if this is just tighten-able or if I'm going to need to replace the entire setup. It's not the fork tubes btw, it's the actual main single tube that goes through the frame to the bars.  Thoughts, suggestions? PS: Man, I'm kinda nervous to be working on a 4 stroke. Such a complicated machine, relatively... But again, super excited to have a new scoot to mess with. ;D

Pull the spark plug out and you may get a clue as to what you'll find in the engine. I would suspect it's going to be lean unless the person knew what they were doing and jetted accordingly. Even if it were lean, that doesn't mean you can expect to find catastrophic failure. I would suggest taking apart the steering stem and checking the upper and lower bearings. You might get away with tightening the nut, but it's a good idea to check the condition of both bearings. Replace if necessary. Clean and add fresh grease. Looks like a good deal to me. For $200 I'd buy that with engine issues (every scooter needs a big bore kit anyway  ). There's one sitting in my garage just like it, very close to that mileage, that I would give the owner $500 for and he only paid $1000 shipped a couple years ago. It's a nice scoot. Pretty much like the Triton or Strada but with a 150 and 13" wheels (feel the same as 12s to me). 49ccscoot.com/roketa.htmlOh, one thing that I really don;t like about those scoots is the lights. The headlights project a really narrow beam. I stuck a 60W high beam in my friend's scoot and that does help. No problems with it so far (some folks say it will ruin the electrical system from the extra load). I use 55W lights on T2, and 45W on T1, no problems on any of 'em yet. Another solution might be a Triton styled front fairing. Never tried, but it looks like it should bolt right on. |

That roketa looks exactly the same as this tank. The guy said it will do 70mph, but I find that a little hard to believe. I'll check out the lights when I get a chance. Might even pop the front end onto my Mati to see how the lights work, if it won't fry my electrical system.  As for the bearings, can I just replace those by themselves? I can actually see that the bottom one is rusted out without even taking it apart. Where would I buy bearings alone? |

The Roketa with a 150lb rider does about 60MPH max (real world, not Chinese gagues). I can't remember if the bulbs have the same connectors. If they do, I don't think it would hurt. Are you saying the bearing or the race is rusted. The bearing(s) should be either a bunch of ball bearings placed into the races or set of ball bearings in a cage that can be replaced as a unit. The races are where the bearings ride... what's attached to the tree or the steering stem. Either can be replaced. www.partsforscooters.com/Front_fork_race-_bearing_gy6-100-104www.partsforscooters.com/All-Parts?search=steering+bearing |

That sounds more realistic to me, 60mph. Still, that is a lot better than what my scooters are doing Nice link! I can never find that kind of stuff. Probably helps to know what it's called Here's what I'm looking at. Again, I know I should take it apart, but I don't have the time or will power to right now. Will have to wait!  That's with me pushing up on the frame. |

That's the caged bearing and the race that's rusty, and not greased. Apparently the stem is loose too, because you shouldn't be able to push on it to see in there. I'd definitely replace the upper and lower bearings. You can probably clean the rust off of the races with a wire brush or some light sanding unless it's more than surface rust. Definitely make sure you get that done before riding.

I'm not sure those races are right, actaully pretty sure the 2nd one isn't. I believe you actually want 2 of the upper bearings. Definitely not that front fork stem bearing.

Yeah that's why I held off on ordering until I got the input, that bottom one didn't look right to me. So you think the top bearing should work for the bottom, as well as the top?
I'm just going to wait until I get it apart to order - I guess. That way I can get all the measurements and match everything up to the pictures and not have any issues.

Nice scoot! It's just like the one I'm getting. 55 MPH is a more realistic goal. If you take apart the speedo cover you'll see two large nuts on the steering stem to tighten up the play in the bearings and to remove the stem. You have to pulkl the bars of course. It's just like a big bicycle. The lower nut is the actual upper race and the upper nut locks the whole thing in place. I use a monkey wrench for those.  |

I'll give tightening it a try first with a good long spray of WD.
Do you guys know where I can get a replacement airbox? All the ones I can find aren't whats on the scooter now. How big of a difference does a free flow filter make on these bigger engines (in case I just want to slap one on and upjet)?

Yeah, I think the upper bearing will work on both ends.

Oh,
I just noticed the back brake cable adjuster nut is running out of adjustment. I think they installed the lever wrong in the factory and the cable has stretched a little. If you remove the actuating lever from the rear and rotate it one or two teeth to the right and reinstall it it'll give you more cable adjustment again. The brake shoes are prolly still good with only 2000 miles on it.

Holy shit it really does look identical to the one you are getting!
And good call on the adjuster. I hadn't even noticed. I think these guys were the type to go messing with things without understanding what they were doing. I can tell they took apart the plastics and couldn't get it back together right. Broken connectors and what-not all over the place. A shame, really. I'll do my best getting it back together properly. I'm dying to know if they upjetted it too, since they cut open the box. I'll post some pics of the tubing mess under the seat as well. It might be normal, but it looks a little crazy to me. Tubes EVERYWHERE.
So what is the normal jet size for these things, and where can I get a set? Sorry about the million questions, but I figured you 150 vets might be able to point me in the right direction.

So I'm getting them now.
