When I sprayed starter fluid onto the outside of the right-hand side of the carb (idle adjust side) I noticed my rpms went down. Figured it was a fluke, but I tested it several times. I had read that rpms should INCREASE or do nothing; an increase in rpms would indicate an air intake leak. Is this gonna be a Rubixy Cubey type of deal or y'all know somethin' 'bout this? I'm still not satisfied with my reduced top speed from last year (now going between 25-30 avg.) so I keep poking 'round.

Update: hope I'm not confusing everybody with the updates--just trying to give a meticulous account of all that has gone on in the event it helps somebody else. If mods think this thread is too "winded," I'll be happy to consolidate all this in one post and we can delete the thread and I'll make the new post.
Anyway, while things were much improved with the rear tire change, I still wasn't getting the speed I wanted, and felt a slight bog on the very top. Went ahead and put the stock airbox back in in place of the cone filter; much smoother, nicer ride after adjusting a/f (and may have to adjust it more) to where I can max out throttle with no bog (just no gain in that top quarter range of the throttle, as expected) but it was a really windy day to test ride, so I was going 30 one way but got well over 40 another way, so that's putting me above 35 avg which I'm liking. I was really hoping these 9g sliders would give me just a few mph w/o much loss in acceleration, and it seems I've both gained in acceleration and top end. We'll have to see how this pans out when the wind dies down and everything is seated (since most stuff is "new" again...). Thank you all for your help. I think one of my final issues may be as bashan stated above; old gas with too much seafoam in (I put about a half a can in, total).
UPDATE: Nope, still lost top end. Have not solved issue yet. From what everybody is saying, most likely cause is: hole in piston, air or hose leak. I will update when resolved.

Well it may have been coarse but I didn't know too much Seafoam was a bad thing, so thanks for the new info!

First thing that pops in my head would be add some like the cafe Races that mount at the end of your grips. Not sure what all would be involved in doing it. I thought about that; had seen some on amazon but something about them didn't look right... just made the bars feel too wide. Could have just been the pics they used. I wonder if anybody sells a "quality" version of the connector/mechanism that holds the mirrors. I would have just used quite a splash of loctite on them if I had thought about it. Guh. |

Well I doubt that anybody that KNEW what you just described would allow it to happen; I didn't know. Some of us are just starting to learn about scooters. My lawn mower, weed eaters, chainsaws, and leaf blower never had a problem so it wasn't intrinsically obvious to me that it could be so detrimental to leave something unused for a season.

I stripped my mirror sockets out like within a month of having my scoot for how many times I had to adjust them after they vibrated loose. Anybody else? Solution? I can't fit wrap-round mirrors anywhere as far as clamped ones go.

Update: APPARENTLY the rear tire was the (biggest) problem; the old tire had about 4 oz. of liquid in it. I had used fix a flat once to seal what I thought was a slow leak that was actually coming from a loose valve stem; does that stay in liquid form? If that was water, HOW? And would that liquid put the tire far out of balance or did sitting all winter somehow warp the tire?
So now, instead of a quick jump out of the box to about 8mph, then a slow climb to 25 mph max with heavy bogging if suddenly accelerating on the throttle, it's quick all the way up to 25 and fairly quick up to about 29 mph with no bogging at any point; I believe all that remains is me tweaking the air flow issue (currently still have partially taped-over cone filter on to control what was too much airflow) to get me up to about 36 cruising since I upgraded from 7 to 9g sliders (can't help but wonder how 7g to 9g introduced INCREASE in acceleration unless it's a powerband issue--I'm 6'5 243lbs.)
NOTE: Rear wheel still doesn't "spin like a bicycle tire" as I had been told it would. With a medium strength spin, it goes about 1 turn and stops.

Update: Replaced variator, Dr. P. sliders, and plug today. After changing variator/sliders which was going from 7g to 9g Dr. P. Sliders, I actually gained low end acceleration somehow which I didn't expect, but am still maxed at 25mph. New plug didn't help. My last "swaptronics" hope is to finally replace the rear tire; hoping desperately that it became warped or something over the winter and that's what's causing this. Then if that doesn't work, I'll put the factory air box back on and/or loosen the exhaust to see if there was an obstruction and hope for a miracle before harassing the boards again.  For an update: 1. Wouldn't start and remain started, replaced carb 2. Starts, idles fine, but maxes out at 25mph and it takes a long time to get from 20 to 25. 3. Replaced: plug, belt, variator, rollers, front tire, air filter (for cone style--still seems to be getting too much air), fuel filter. 4. Inspected as much as possible: air and fuel lines, intake manifold, rear and front wheel movement (rear wheel does look just slightly off but not heavily warped--not sure if this could really be the cause of this). 5. Adjusted: valves which had slipped to .006/.005 so adjusted both to be sure, .004/.005. Fuel/air mixture multiple times along with idle per Alleyoop's methods. 6. Only change noted from steps 2-6: increase in low-end acceleration after variator/heavier slider change. Thank you guys for your help so far and all input is appreciated. |

I know, they are aren't they? Mine is an absolute requirement right now. I got one and actually lost it (was ghost hunting, somehow knocked if off of my scooter seat before coming home and didn't realize it since I don't get uncomfy for about 5 miles of riding on the seat) and I put out "wanted" posters for it! No luck there, so I had to buy another (but this one is strapped down; last one just sat on seat).

As long as you don't flog the motor the trip length is determined by your butt's endurance on any well prepped scooter. If you ever want to win the "butt endurance," game, get yourself an Airhawk II (cheaper than I, does the same thing) seat cushion. It works miracles. This is the small one on Amazon--my review is the one on top: Airhawk II seat cushion |

I've only done about 50 miles, max, and that was with a break. It's good to see that there are apparently no major issues that creep up with these lower-powered (and I hear, "lower quality") Chinese scoots after the major components are upgraded just from doing a long trip. I'd like to do a long range "camping/touring" trip with other 50cc owners but I always worry about traffic getting pissed off (cuz I know I'll rip the wrong cager's head off, and I want to avoid that situation). I wish there were some scooter/cycle lanes for just that type of thing.

I'm in the same boat re: top speed. And I've just about replaced everything; last thing I'm doing is putting on new variator and sliders (taking 7g dr. p to 9g), replacing spark plug again, and finally getting my rear tire replaced (I've had the new tires for almost a year, just getting around to replacing them). I'll post an update on what ultimately fixes it.
