UPDATE: Using the Valve Adjustment Tutorial: GY6 : scooterdoc.proboards.com/index.cgi?board=engine&action=display&thread=140I adjusted both valves at .004 which seemed to work better than .004/.005. Made sure the timing marks were set right. Bike started up a bit better, but still wont get up and go. It wont start and stay on unless its on the center stand and the rear wheel is spining. It still has a ruff idle. When off the center stand and with kickstand up it will crank but wont start. It seems to have no idle and wants to just get going. I'm sure if I was on a hill and and coasting down hill it would go. ( weird notion though I know). I hear some minor clanging noise coming from the (kickstand) gears. NEXT I guess I'll take a look at them gears again to make sure there alligned right. I did replace them just like the picture that sprocket sent but I didnt remove the (crank shaft gear?) that my nephew had taken off to replace the belt. The one all the way on the left. I need to make sure it is alligned on the mark. Ohter than that I'm gonna have to pay out the ying yang and find a chinese mechanic. lol I mean a mechanic that workd on these Roketas'... |

Howdy Folks - I will send for a repair guide soon - Latest Update - Got my new (ac) CDI and was a snap to replace - Scoot still up on the center stand - Started a tad bit easier but still runs ruff at low rps and as long as that rear wheel is spining it will stay on - It did idle on its own for a bit but eventually quit - As soon as I hit that left hand rear brake it shutts off quick - Note: All my electrical problems began when I had no brake lights - Motor turns off as soon as I push it off its center stand and try to get er to go - It just sounds like its out of timing? - When my nephew took off that sprocket on the left side to install the belt I wasnt paying attention to see if that gear moved out of alignment - QUESTION? - On that picture that Sprocket sent above for the Kickstand alignment marks - The gear (#1) all the way on the left- If it was moved out of its mark < (is thers such a thing?) to replace the belt - would that cause a timing issue >?? I know you mentioned the valve adjustments, but my scoot was runing great before I lost that belt - Talked to a Scoot Mechanic who said he would charge $60 to check the wiring and around $80 dollars or so to re-do the wiring issue - All I can think to do on my own now is check them gears - Will wait for your kind responses. Thanks - Sleepless in stx  |

Hmm - I'v always started the scooter when just on the side kickstand and only on the double (center) stand when I needed to use the kick starter. UPDATE - That former CDI (ac) mentioned above. I noticed the light still remained yellow when it stayed on as it was always green before when on. The idle adjustmant helped a little but it still wont drive. So I ordered a new CDI. 5-7 DAYS. I'll update when I replace the new one. Thank You Very Much...

I'm confused? Scooter always started when just on the kickstand. The only time I ever used the double stand - when tires up in the air - was to use kick start. I'll try the idle adjustment though.
Thanks > Should I start a new thread or keep this one going>? ty - Louster

Ok Gents - I really appreciate all your advise and this Forum.
One more update. Placed the scooter on its double stand and replaced the kickstart gears. It started and stays on as long as it I keep rpms up a bit. So I reckon its not a bad CDI? The engine sounds fine at higher rpms. It wont idle on its own and will die if I let go of throttle? While runing I push it off its stand to try to give it a go but it wont and soon dies. It wont start if its not on the double stand. I'm going to look into the valve adjustments and a new spark plug next. Getting close but no cigar, So close and yet so far? Any more suggestions >?
Thanks once again... - L

Greetings again everyone. Well tried starting my Roketa again before I replace the gears. My nephew noticed the CDI light was YELLOW not GREEN like before - this is the link to the exact one - CDI - High Performance racing CDI for the GY6 50cc, 125cc and 150cc engines. www.scooterdomain.com/GY6_Gas_Scooter_Parts_p/gy6cd27336.htmHe thinks it may have fried due to by passing the fuse link. Does the little light start yellow and turn green after it starts and stays on OR should it be green while cranking. I did not want to order a new one if I didnt need one? The fuel, carb and spark plug issues are OK. Thank you for all your help thus far. Louster |

Well thanks ccprof, alleyoop, jrryan, sprocket, shalom72c billCand mainly for the much needed REALITY CHECK - The feed back, pics and the wiring diagram are awesome. I guess I'm going to have to take my time and try to do things the right way. I'm limited in knowledge and savy so guess I'll look into placing an Ad in Craigslist for a scooter mechanic. Hope to find someone who (hopefully) knows how to work on these chineese bikes. If I'm lucky I might be able to het him to come make a house call. I live in south tx (mcallen) and the the closest dealer is 4.5 hours away in San Antonio. The pics here and the wiring diagram will come in super handy thank you. My problem is time and I'm only off on Mon & Tues. I work retail and get home @10pm so I only have a few hours in the morning. I'll start by attemting to put back the kick start and gears the way they should go. It looks ruff which is probably why my nephew skipped it and he rigged my wiring the quick fix way. He got me running again so I was happy. Then I'll try the carb and wiring in some order. With todays gas prices I'm not ready to give up on my Roketa just yet.. can't wait to get on the road again...Will keep you nice folks posted. Thanks again everyone.

WOW - Thanks folks for all the input - lots to check out - will check out the tech section next chance.
QUICK UPDATE - Took off the air cleaner squirted some quick start into carb and hit the starter. It clicked a bit and nothing - on the 3rd or so attempt it cranked strong again and seemed to want to start but no. I saw some smoke comming from the red positive cable wire that goes to the positive uptop to the battery connect. Oh and I did not mention earlier we had hot wired the starter switch b4 with a new wire running from the starter switch on down to the selenoid switch, battery wires and such>? (My nephew again) It had worked fine since and we also had to tap into the brake lights with a new wire and new push switch monted on the bars for brake lights. ALSO I'm headed to AUTOZONE now to buy a new fuse link thingy that was taken off beacuse it was cheesy and broke off. I know thats a big NO NO. Now I'm thinking electrical issues. I did put fresh gas in it but I will look into all that was mentioned eventually one by one. I really appreciate all your input and suggestions...Thank you very much.

Hello fellow scooter dudes and dudettes!
First a little about me. I chose the name Dawg named Scooter because when we used to have a dog named scooter. Simple enough right? 1 year ago I bought a 2008 150cc mc-13 bali jmstar (blue) with 4500 miles and it has ran fine up until 3 mos. ago. I'm not really a mechanic but willing to tackle minor issues with enthusiasm. Mainly to save some money ey? So far I replaced a battery and a starter and it cranked right up like a champ and ran fine for a day. Then the next day it CONKED out on me on the way to work. I found the drive belt (Gates powerlink-835-20) busted. Replaced it the with the same exact one.
Heres the problem, my nephew (25yrs) is a motorcycle mechanic and he helped me change my belt. Only removed the left side clutch pully thingy to replace belt. Used a breaker bar w 17mm. Having had issues with my kick start b4 we left out the 2 gears used for the kick start. He said they were not necessary to have the scoot run as good. IS THAT TRUE?
I figured I would replace them at a later time and it looks easy enough. OK so my CURRENT PROBLEM. It cranks plenty good and seems to want to start up, but it just wont stay on. I dont want to fry the starter again. It was left for a week on its big kick stand (covered) while waiting for my part to come in. Maybe some dirt may have slipped in underneath? I'm guessing fuel line problem. It had cranked right up before the belt exchane just 1 week ago. It was pretty low on gas so went to the store and added a gallon of premium gas (always use premium). ANY HELP would be greatly appreciated. Will send pics later. THANK YOU VERY MUCH.
