i found my 50cc locally for 300 bucks. (used) it was a really decent chinese scooter and probably still out there running. i found my 250cc semi locally for 1000 bucks with 80 miles on it. this scooter was a total pain in the butt until i ironed out all the problems with it. after i ironed out the problems, she was a real screamin' queen. so beware, there are good ones and bad ones. The problem is she just went through this and would have had to replace literally every single thing besides the crank and topend. Luckily she found someone who wanted to buy it off her for parts for the same amount she bought it for so I told her to just get a new one to avoid that again and have been helping her to find one since. The scooters at killermotorsports seem nice |

I saw that site. It looks great but my friends budget is tight to about 500-600 maybe 700 after shipping. She also wants it to have the "retro body style" so it's hard to shop for her.

Well if you have done everything right so far then you must go back and diagnose the issue as if it is brand new and unrelated. It is possible a dirty carb, bad plug or coil or cdi or a clog in the muffler or something else weird could have been causing the hard starting if the valves have done nothing to help. The gap should be 0.004, that's two zeros before the 4 not one after the point mark.
An extra 0.001 wont hurt it but you need to find the best tune for your machine. I just use 0.004 as a standard starting point and adjust from there as far as 0.003 to 0.005. I have actually adjusted as far as 0.006 without issues just clicking noise, just saying it can operate if it isn't exactly right, but you benefit much more from tuning ti to your specific engine which may or may not even be the gaps recommended by us or the manual.

Set them to 0.004 inches. Both of them. Not sure why you say 0.004 is a very large gap to you, to me it is thinner than my fingernail! What are you comparing the gap to, a dust particle? lol
Did you first set the gaps when the engine was cold? It sounds like to me you were setting the gaps while the engine was warm which is going to completely throw off your adjustments. You can set them all day and night long but if the engine isn't cold then you're just killing time and most likely giving yourself a headache. Make sure the cam is at top dead center and the 2 small holes line up with the engine casing.
It may also be possible you have multiple problems and you just can't see past your valve issue because it is the most prominent issue at the moment. I've never had popping sounds from poorly set up valves. However if you loosened the 4 bolts around the cam you may have pulled the head off the cylinder a tiny bit while you were working and damaged the head gasket. Once it separates once even a tiny bit it can form leaks because the way the gasket is made is to only be torqued down once and then never removed. It kind of sounds like this may be the underlying issue.

I'm trying to help a friend get a brand new scooter online. I used to go to scooterdepot.us to get super cheap prices for scooters online for my friends but now the site is gone. Can anyone reccomend some good trusted sites to buy scooters from online?

What spring washers are you guys talking abuot? Just wondering, I tried using springs before to dampen vibration on bolts but they would always get pushed out by the springs. There's an actual washer that is a spring or something?

I don't ride 2 strokes really. I just have an antique 2 stroke moped, and the 2 stroke that I needed to get to a gas station was a friend's but I ended up just convincing him to walk it to the gas station up the street haha.

How would adding 2 stroke oil to gas in a gas tank like 50:1 effect the scooter if it already has a seperate tank for 2 stroke oil? Would it run too lean/rich? Would it clog the carb? Just wondering if I can use my spare tank of gas with some mixed in 2 stroke oil in a 2 stroke scooter that has a tank for oil already just to get the scoot to run to the gas station, otherwise I would need to find a place to dump the rest of this gas which I think would be harder since no gas station or auto store around here will take gas, and my 2 stroke is full to the cap otherwise I'd put it in there so I could get the other one to the gas station.

The washers go on the outside of the heat shield. Make sure all the bolts are tight and only tighten them before you first ride, otherwise heat expansion etc... It goes bolt>washer>heat shield>muffler. You may also benefit from using some sort of adhesive meant for high temp, or paint. I used rustoleum on my heatshield it can act sort of like an adhesive if you put it together before the paint entirely cures.

Ugh the noise came back, not nearly as loud, but it's back. Maybe the final gears got damaged or something. It's not the belt, tried changing it with a spare, same thing. Maybe spandi is right. I mean I ride this scoot like a couple times a month, I ride my other scooter multiple times per day, so it's probably jealous. |

I figured it out. Although the cluth was new it was the cause of the noise! Seems it came with a bad bearing. I switched out the clutch with an old used clutch and the whining went away altogether. I figured it was the clutch because I took it out for a ride yesterday and I noticed after I turned off the engine and let myself roll down the hill in my backyard to my shed I heard the noise again. Since the engine was off that means it had to be coming from somewhere between the clutch and the rear wheel.

So one of my scooters has been whining lately. I thought it was either an intake or exhaust leak. The intake was fine. The exhaust was not, the flange on the muffler was crooked. So I replaced the muffler and there was no change. It still whines just as much as it did before, the new muffler is completely sealing though and it not leaking.
The noise happens all the time pretty much, goes away on acceleration but you can sort of hear it while maintaining speed and then when you decelerate it sort of sounds like a loud whistling whine, like a siren from a police car sort of. I checked for oil seal leaks and there do not seem to be any, nothing is visually wrong anywhere. Not really sure what to make of it but it doesn't seem to effect performance at all, but the noise is very annoying.
