EDIT: Re-titled this post, Blah, blah, blah, scroll down for updates Hello all.
I'm the one posting about my new Bashan Peace Sports 50 2009 scooter (49.9cc), the first scooter I've ever owned that's street legal.
Currently my top speed is 20mph and there is no full throttle. It takes possibly a solid minute before I can reach 20mph on a flat road too. I'm using a busted up throttle case assembly right now, but I'm positive that's not the issue.
It appears to have a sort of sweet spot at around 75% throttle, but anything higher than that puts it back in idle. What's going on here? As far as I know the carb has never been cleaned and despite having 1.4k miles on it it still had the stock sparkplug and oil (the previous owner must've hated this poor thing). I've since replaced the sparkplug and oil and there's no more dying at stops or bogging during idle, but I still have this issue with the throttle. Is it just normal to not be able to go over a certain throttle percentage? I can't join traffic going 15mph for a minute before I reach the speed of the other cars.
I currently weigh 240lbs, but carrying a 20lbs bag of salt didn't seem to effect performance.
So... I'm sorry for my poor description skills, but what should be done, in your opinion? Is it the carb? The fuel? The idle? The air/fuel ratio? The fuel line? or something I'm unaware of? If at all possible I'm willing to have a go at any possible way to draw more performance out of this thing with some direction. This is my primary and only vehicle, I need it to be able to go just 35mph, not 25 downhill. Is this even possible to achieve? Because right now every car is passing me in the neighborhood on my way to the local grocery store. Main roads are just an impossibility.
Should I sell my precious first scooter and try to get a 150cc or is it possible to draw enough power out of it to go to my optimistic goal of 35mph?
UPDATE 1/19/13 Still working on hitting 35mph, I can go up to 31mph right now, just looking for that last limitation. I got my feeler gauges in the mail today, so I'll be doing a valve adjustment soon.
UPDATE 1/20/13 Finished the valve adjustment, hearing no clicking. Haven't been able to ride for almost a week because of my hurt ankle, but I'm still working on it. Ordered a new battery and now I'm trying to figure out my throttle problem.
UPDATE 1/23/13 Tightened my throttle and it seemed more responsive for the few minutes the scooter would run. Found my old work boots and they have been helping support my ankle, I'm feeling good enough to go for a ride in the chilly weather. I'll be updating again once I get my new battery!
UPDATE 1/24/13 Got the battery yesterday, tried charging it but the light instantly went green so it came fully charged as advertised. Loosened the throttle a bit as gasoline was coming out of the muffler like no tomorrow trying to start it with it as tight as it was. Been trying to start the scooter for two days now! Boy, do I regret ever letting it with an empty tank of gas. Heet seems to have made the scooter able to start for a minute at most, but it won't stay running no matter what I do. I'm thinking the cold weather has something to do with it. Or maybe everything to do with it, I'm not sure.
UPDATE 2/3/13 Took off my carb and drilled/chiseled out the plug that was blocking my a/f. Put a #90 jet in there and my throttle dilemma seems solved. Have yet to ride due to bad weather though. I will continue to update this thread as I was updating through scootdawg.net for a while and now some of my progress is lost in history. UPDATE 2/15/13 Finally got to riding today! After weeks of bad weather. My throttle is great and responsive, I can go full throttle no problem, and I have finally reached my goal of 35mph (uphill no less!), I know I can go faster, but I have yet to find a road I'm willing to try to on, haha. Things to do: New Spark Plug Change oil-10w-30 Change gear oil 80w-90remove cockroachInstall Throttle Case Assembly Install New CVT Beltde-restrict (if possible) (no restrictions found, maybe the CDI?) Install new battery (YTX5L-BS)P!Adjust Valves Adjust IdleClean CarbAdjust A/F Remove airbox and replace with filterRe-JetFind/Order New 10mm Bolt for Kickstart Get New turn signal bulb (R10W12V-E13-282) Get New CDI Get New CVT Rollers Change Clutch Springs Install Big Bore Kit.

It is definitely possible to get 35mph downhill (that's a rather modest goal). The only question is; is it worth it? If you have the resources to grab a 150 and you're not the mechanic type, I'd go for the 150. Otherwise, get ready to get your hands dirty. I'm not the mechanic-type. I'm a computer guy, but this scooter forced me to be the mechanic type. I don't like always having it torn apart but I will say that after putting a few hundred bucks in it, it's respectable for a 49cc. People are going to tell you to adjust your valves, change gear oil, check/possible change clutch springs, rollers, hoses, clutch, belts, housings, and CVT and possibly CDI, as well as spark plug (even though yours is new, is it gapped properly and is it NGK or a comparable quality and iridium?) Just a heads up, two cents.

^^^^^ everything he said^^^^^^
but, gee how do i say this your a bit big, hun im only 130, im a woman my 150 cruises at 55
im sure your in love with your 1st scoot so was i, and still am
you can spend lots of $ to get what you want in speed but i think getting a 150 fall in love with it, and you 2 will have a wonderful relationship.

I'm 290 and my 150 tops out at about 55.... it will cruise at 50 all day tho and I'm bone stock. I keep it tuned tho. It does a real repectable job of keeping with traffic.
I'm thinking I'd go with the 150 by the time you are done getting a 50 4 stroke modded out, you would of got the 150 and the 150 will still out perform the modded 50.
If you stick with the 50, before doing any mods, getting it running properly will do you more good. (yes and what he and snugglebunny said ^^^^^), do a valve adjustment, clean the carb and replace the belt. These three things will do more to get it running properly then anything else. Fix the throtle houseing (I assume you are taking about the throttle control on the handlebar)...
For things like the controls, make some scooter buddies in the area so they can tell you the shops that have a "junk yard" in the back so you can get parts uber cheap... ^--^
I'll bet you can get 30mph just doing these maintanence items.

The money i put in mods on my 50cc to go 60mph it would of been much cheaper to buy a 150cc, I have my scoot more for a hobby though so i wanted to mod it, i say sell it and get a 150 i have ran against 150's and have bested all of them to date

Hi A properly tuned stock 4 t 50 should easily hit 30 to 35 mph. there has to be something wrong with yours, it also may be restricted I would check your cvt first Take care and ride safely Yours Hank

I always get the same response from the challengers " I have a 150cc no way your 88cc scooter is faster" and always when i best them they say " it just doesn't make sense" anyways get the 150cc its cheaper and more reliable in the long run

Hi My stock Sr 50 has hit a high of 51 mph at 8,000rpms red line is at 12,000 aprilia gauge by inuyasha50, on Flickr Once i do upgrade her to a 70 cc bbk she will be a 4t 150cc killer if i go up to a 90 cc bbk possibly even 4t 250 cc killer You cant place 2t scoots with 4 ts as theres no comparison in terms of performance Take care and ride safely Yours Hank

Just a heads up, two cents. Thanks, Wutz! (and everyone else!) Right now it would be another long craigslist hell to trade up for a 150cc, it took 5 months just to trade my favorite laptop for this Peace 50. Plus I would have to get a motorcycle license. Here in Illinois, anything titled 49cc or less doesn't require one. I'm a computer person, but so far I've been able to follow directions when it comes to tuning stuff on scooters. I cleaned the carb on my honda zook, I don't see why I can't on this. And if I can clean a carb I don't see why I can't do other stuff similar to cleaning a carb. By the way, I'm glad I started a "debate" of sorts on 50cc vs 150cc :]

go with a 150 or a two stroke or welcome to the land of modding your 50cc four stroke it becomes a hobby of sorts

go with a 150 or a two stroke or welcome to the land of modding your 50cc four stroke it becomes a hobby of sorts I'm hoping for it to be a lifestyle change of sorts. I've heard that these chinese scooters require constant maintenance anyway, haha. If the gear oil isn't changed would this effect my performance? I don't think the previous owner did any maintenance on the thing at all. Btw: my sparkplug is a stock ngk, iridium plug I believe.

Hi Yes indeed it could, you may also have a dry gear box( no oil left) which could cause the gears to seize up eventually, i would give her a pdi to be safe, whether a brand new or used scoot its a wise decision to give them one x1scooters.com/pdi.htmlTake care and ride safely Yours Hank

Hank... yours is a fuel injected 2t isn't it? I still haven't been able to get my hands on a 50cc 2t to ride and try.... Maybe one of these days, I'll pick one up for the pure fun of it.

I'm pretty sure this will be my next big investment in the bike, but right now I'm a bit strapped for cash. Are there any parts I could throw on my Newegg or amazon credit for the time being that will help my performance? I've noticed they have bore kits on amazon; are they worth getting?

whatever hank said! I'm only 170 LBS, but I'm absolutely sure that a proper tuned 50cc 4 stroke should hit 50MPH with ease!
Mine is not properly tuned, and I go 48MPH. Spark plug, air intake, exhaust, jetting, CDI, rollers, and variator/cvt/gearing ratio are all possible limitations.

Well, im 300lb and with a 47mm bbk and 6g rollers on a 90main jet i can bury the needle going down hil, amd can hold close to 40mph on the average road. Im sure others have talked about carb adjustments and such... But its very possible... Though a 150cc is the easier option

My scoot was tuned with the 100cc kit and it maxed 48GPS i had to put in the bigger kit and new gears to break 50 gps it ran 54 with the 110cc kit with a 20mm carb I hit 60 after I put in the 24mm carb

Changed the gear oil today and it seems to ride way more smoothly. I'm getting about 5mph more now. Hit a new top speed of 31mph downhill and seem to be able to cruise at 25mph. Now to do the next things on my to-do list... Things to do: Change oil Change gear oil
Throttle case assembly (on its way) New turn signal bulb Clean carb adjust idle adjust a/f adjust valves get new cvt belt new cvt rollers change clutch springs de-restrict (if possible) Get new battery (YTX5L-BS) And finally... Install big bore kit. Anything missing from my list of to-do, for more performance?

Post by urbanmadness on Jan 9, 2013 19:03:55 GMT -5
after the big bore kit, you will need to rejet the carb.
The things I'd do first are change the belt, check the rollers and adjust the valves. You might even invest in a set of rollers however, since you are talking about a bbk, do the rollers after that unless when you change the belt they are in rough shape.
Tuning the variator is a very good "bang for the buck" item.

Alright, I've fixed my throttle housing assembly, I've changed my cvt belt, a new battery is on its way (I never want to be stranded with no electric start again! Argh!) and "clean carburetor" is on my to-do list. Now I'm about to adjust the valves, but am very confused due to conflicting information. Some say it's easy, others say I will permanently damage my engine just for thinking about it. I've seen almost all the youtube videos about doing it, but I'm still a little bit concerned that I might be stumbling into the territory of rocket science and brain surgery. Are there certain factors I should be aware of to prevent permanent damage? Someone recommended I adjust it for .002 intake and .004 exhaust; is this optimal? (sorry I can't remember who told me this). I got my scooter used, so I do not have a manual, and google isn't nearly as friendly as you guys. scootdawg.proboards.com/index.cgi?board=talk&action=display&thread=57532 this thread is a pretty good one, but it is rather confusing to follow. Oh yeah, my engine, for those that don't know, is a 1p39qmb

Thanks Teddy. I opened it up tonight and checked; .0015 won't even fit in there! My thinnest feeler gauge won't fit in there! It seems to me that it's in dire need of a valve adjustment! I've seen the video before, but the pictures helped a bit. Turns out for my scooter you only need to remove 4 bolts. I removed the 2 nuts by mistake and simply screwed them back in. Does one have to turn the fan to get TDC, or will the variator do? I already had my cvt case open, so I tried and either way seems to work. Is that bad?

either way, just make sure your marks are lined up to make sure the cam lobes are not making any contact with your rocker arm and applying pressure to your valves but they must of been pretty tight
