If someone could verify with me before tonight is over 'Same day shipping', Is it possible get a throttle cable that is too long with to much slack where as the trottle wont engage all the way? I am looking into ordering: www.amazon.com/dp/B072TZ9BJF?tag=viglink20248-20It's 78 inches long, I didn't fully measure the actual cable, But slide the broken wire out instead and started doing measurements, My wire is 68 inches long. If I route the cable maybe near the gas tank then back to the carb "if it's even that long", Is it possible the wire would have to much slack where I couldn't open the throttle all the way? My broken cable is technically too short, It stops basically right at the carb, So being able to route the cable to be more hidden would be really nice!

I'm not going to lie, That's a really nice kit! Mainly because of the price. Is this the kit you ordered? If so what speeds are you averaging?
Also thank you for the information on Longbo, I read that somewhere, as well something about low. I figured maybe it was a low end model. But typically Vip model scooters always had better builds so dunno.
I easily have the money for it but I want to pay off some credit card debit first :/.
I don't entirely know that much about engines, But I don't have to replace something like a cam shaft with this? Some bearing or anything inside of the engine, lol?
Once again thank you!

Thank you for the info on the plugs ! Yeah I'm sure I need rings as well, possibly whatever is considered a rebuild. I noticed a lot of oil all over the engine, more like slime. My theory is the actual gaskets at the head, and that's where I might have my true 'power loss'. I just haven't had the time to take off all that plastic :/. I will have to look into the kits, but my engine number is odd, mines a lb1p39qmb. So far qmb parts are interchangeable.. No clue what the L is for

Cant ride to work today, So somewhere around the top of the block 'more like around the cover' and the air filter when it idles down a little to low and cuts off I will see either vapor or smoke, cant figure out which it is, but it mainly comes out the air filter, And you might see a tiny spit of it at the block area at random when it dies off. Dunno much about engines but maybe someone hear can help me with what I should try to do. Any help is highly appreciated
Problem solved, Failed to consider that the new air filter was taking in way to much air..
I think the bike might have compression problems

Yeah I tried 2 and a half turns for a stock setting and that still caused the idle to die down 'went bellow 1500'. Sorry I should of mentioned that, I stopped at three and a half turns and it still runs the exact same. Tried getting it at basically no turns and it was basically the same. I suppose I could open it almost all the way to see what happens as a test, I also failed to mention I am temporarily using the new K&N style air filter, So there might be temporarily to much air going to the system for all I know, And it probably needs to be evened out. I will disconnect the vacuum line off the intake as a test to see if it purrs. As for the needle you'll have to read the plug to see what it is needing under load. Dunno what you mean :/ Also in that kit I received some jets, ones a 85, 88, 90, Haven't researched them yet. I think the one I'm using is a 50 - 60cc basic jet setup. I know the scooter I have cant be a true 50cc as it would almost hit 50 mph sometimes, would take a little while lol

So after buying the entire carburetor kit the scooter is very close to actually running better. Other than being told the scooter now sounds like a crop duster in the distance... lol.
Now I suspect a air fuel mixture issue, I will have to play with it a little more tomorrow to see if I can perfect it.
But now the scooter will instantly attempt to hit past 7,000 rpms on the center stand and it seriously wanted to keep going, no screaming to it either, and when actually riding it I only seen 6,300 rpms, Just 100 over than the original.
I obviously need more gas as when the scooter idles it slowly dies out, but a few throttle pumps will keep it running, I will attempt to prime it while it's running before taking it apart and adjusting the needle and jets. If it runs better, Than I need more gas. If it cuts out might need more air. Any of that right?
Or might still need more gas by adjusting the needle but play with the idle mixture screw and see what happens? No clue man xD

Lol.. I'm not good with math, And that's something I am still learning with these these kits as I dont want to end up with what you stated.
As for weight, I was told by a mechanic many many years ago and I cant recall how he worded it so I will attempt to put it as he said but go a little far fetched with it.
'If you have a stock 50cc kit that weighs 10 pounds total and the piston is light, And you have 80cc kit that weighs 40 pounds, As well a heavier than normal piston, There is a high chance the 50cc will be faster'.
He worded it so much better :/. Maybe you could understand the logic to an extent.

I've had a variator go bad before. The Reason: So there is supposedly a direction the side wall of roller weights are supposed to face, if the side wall is put in facing the other way than they should, the copper will slowly slide out from the plastic on the roller causing the variator and walls to get DESTROYED! 'I had to run and push it and give it gas on takeoffs that day just to make it home lol, embarrassing ...' One thing I want you to answer, Are you driving in nothing but city traffic? Stop and go? This would cause your rollers to engage and disengage way to often 'gears', So your belt is always flexing.. Another thing is your clutch, I would try to see if the pulley part is bent anywhere.. Or see if it's engaging when it should. I would check out the rpm springs or whatever there called. The real simple deal is ventilation, If your cvt area is getting really hot this can easily cause belt bust, it could even be heat coming off your engine going into your port. The next time you get it up and running, Maybe drive for 5 minutes, Then while it's running feel around the cvt area, as well the breather hole. If it's beyond hot then this is always a possibility, I have had a lot of scooters that I have to take many breaks on or I will break down, One of them I still have and that's a geely fashion 2 stroke. Ive seen way better than this, But this is basically the idea, The clutch opening should cause the clutch to work like a fan pushing heat out if I recall correctly, Ive seen some with the same deal but the variator area has openings as well Bet I would personally look into a way to put a screen on the inside of this, less chance of tiny pebbles getting to the belt. Your sceneario is the reason why I slightly miss chain driven, xD like my geely has.

I was currious as to what does it really take to do a swap, Does it require cutting brackets and re welding brackets? I'm really currious, I was thinking of something more like this www.ebay.com/i/221932856884?chn=ps&dispItem=1That's a 150cc Hears a quick image reference I really look forward to a response ::And I do know that the motor mounts are on top. Where as 50cc are on the bottom. It's just a thought I know a crap ton of welders

That's what I have honestly been trying to do.
Something about the thought of doing it yourself, Replacing the front fork, You ride down the rode hit a nasty bump and the entire front fork comes off. Sadly at the scooters age, Any mechanic tries interesting me into there new scooters...
I would prefer to be a part replacer if anything, Parts are really old.
It's weird, I thought the plastic on these bikes were dipped like helmets. Paint has been cracking lately, Mainly from direct sun.
But i do intend to get a 100 cc kit, I just want to ensure when the time comes I get the lightest kit, With the highest mm, Ive seen lower mm then they should be.
Or.. I want to look into the possibility of ordering a 150cc scooter and registering it as a 50cc scooter.... .. .

Might not of put the variator on tight enough :/? Never known for the clutch to fly off.
As for the original bad start, Either the bandito could be bad somehow, Or you just have low battery voltage, Or the starter has grown weak.
I find it best to sometimes rev my bike up at 4,000 rpms for at least 30 seconds before cutting it off as with mopeds and scooters low low idle results in somewhat draining the battery.
Kinda weird.. But haven't had a bad start in forever now.

First off; 2008, Vip Model, GY6, 10,000 ++ miles
Okay so for some time now I have been dealing with a major power loss, The Rpms hit at 5,000 then climb to 6,000, You might see 6,500 in time.
The scooter used to hit 8,000 rpms like it were nothing, Also as if it wanted to keep going, but I only red lined the scooter twice in it's life time 'at max 7,200 - 7,500'.
I have replaced the variator, New gates 18.1 belt, New rollers, a year ago I bypassed the petcock with a fuel switch, Brand new rollers, same weight, And a new stock clutch, after a decade of wear on the old clutch the pads were basically gone... lol. But I just bought another stock clutch for 20 dollars.
I converted to synthetic around the time my speed problems occurred, After doing a synthetic beak in the bike started running cleaner again 'seemed almost like new. I know something is off about the bike definitely, Way before the bike messed up I could open the port from the intake going to the petcock and there would be back fire when letting off the throttle, There is no backfire. if anything you might hear a dododoodoo with a very very low rpm idle, to the extent of cutting off if you dont throttle it.
Just the other day I figured I would play with the primer while it was running, Oddly on center stand the rear wheel started taking off as if I engaged the throttle.
But two nights ago, I went for a gas station run late at night, the air was a little cool, Definitely remember being cold enough for a jacket, The scooter that night actually hit 7,200 rpms, at many points I stayed under the handle bars for better aerodynamics.
My last thought is a valve adjustment, But no one in my area works on scooters, it's a 35 mile trip to any of them. And undoing the cover and doing it just scares me...
My mind is blown, When you read this, if something crossed your mind as to what could be the problem I would love to hear what you have to say.

So my problem has been found. The bushing for the center stand has decade over the past 9 years. The metal piece that comes outward and engages onto that bushing the metal piece itself has snapped, It's like a metal flat plunger. I have no clue what to call this device, But the pipe that has been snapped, So the bushing is the only piece I need to replace as well if I can get just the pipe to replace, If not I know of a welder, But his price is a little to steep. I suppose this is why the rear looked like it was dropping overtime due to the bushing deteriorating, Resulting with metal on metal. Resulting in a brake. Could someone help clarify me on what I need to order? and what could possibly be excluded? Thanks Pst duckey I removed the kick-start as over the years the spring managed to stretch. I have all of the parts I just have not found the time and energy to replace that spring. That stretched spring causes the kick-start to drop and stay dropped while driving over many bumps causing issues.. Just something that got in the way while paying/repairing other repairs. I have not really been to worried about the small time stuff
