My fuel gauge use to stay at full for a few miles then drop drastically. I found the float was broke and barely hanging on.

Ahh! I can get another tach, this scooter didn't come with most of it's parts, and what it did have was abused so I'm not surprised something else is messed up. I tuned it yesterday with the gauge sitting at 2000 rpm whatever that is in real life. I checked for vacuum leaks last night and everything is sealed up nicely. still need to look at the plug though to see what it's color has to reveal. I'm thinking, based on suggestion here, I may be too big on my jets? granted, they are ebay jets and apparently that may or may not be accurate, so I'm assuming it's just kinda feeling around in the dark until it runs correctly. I will look at adjusting the float tonight if I have time, might drop down to a smaller pilot and/or main jet if the plug looks ok. anything else I should check? and any recommendations on a smooth clutch/bell combo? or a place that sells legit Taiwanese-or-better carburetors? To be honest , most of the carbs on ebay " though they are cheep " are actually pretty good. If it were me . I'd go with a 26mm carb with a 120 main and whatever pilot it comes with. Maybe even a 115 main. I do believe you are correct about the jetting. You are more then likely too high for your setup. In have a bigger head and a bbk , and I'm running a 125 main with a 32mm carb. |

That's a lean condition. You probably have a vacuum leak somewhere. You can use a can of WD-40, and start spraying your intake and hoses while it's running. It will bog when you spray the leaky area. Also a verynlean condition could cause unburned fuel to build up in the exhaust , so at startup u get the popping or backfire. |

If you need to make a gasket , what u should do is buy a sheet of gasket paper. The cork kind. Then you can trace and cut out a new gasket that will last . Quoted for truth. Easiest way to make a gasket with cork is put the bowl on the cork sheet with something heavy on top for a few hours. Cut out the indentions left by the bowl, and voila you have a new gasket. That's 100% correct !! |

Alright so this seems kind of strange to me, noticed it a few days ago at a red light and it seems pretty consistent. So my throttle has about an 8th of a turn worth of play in it, basically I can turn it about an 8th before it actually engages and revs it up. Recently Ive realized if I turn the throttle just far enough to before it would make me go, my RPMs drop from around 1800 where they always are, closer to 1000-1200 range, just above cutting off. It doesn't really cause any problems more of just curiosity as to what is causing the RPMs to drop when I'm seemingly not twisting the throttle far enough to engage anything. Wasn't sure if this was normal or possibly the beginning of a new problem. I've had the same issue . I had a slight vacuum leak . |

How's it going. I saw an old SD post about idle rpms. The old member said he had a few different scoots and one called for a 750 idle rpm. We have a member who is having an issue with his scoot and he can get his scoot to idle as low as 500 rpms !! I watched the video and I noticed his idle rpms did not seem any lower then 1300-1700 rpms. When he hits the throttle and the rpms raise to 2000 rpms , his rpms sound much higher then 2000. My scoot idles around 1700 -1800 rpm sometimes a little higher and sometimes a little lower. It just depends on the outside temp. I can get it to idle as low as 1300 at times , but at that point its nearly shutting down . his sounds the same , but at 500 rpms . the problem I see , is that his tach still redlines at 8000 rpms . meaning , if his tach is off , then at 8000 rpms he is about 1000 rpms or so higher.
I wonder if most of our TACHS are not correct. I mean at 1300 rpms my scoot is barely running , but is still at 1300 rpms!! To be honest his 500 rpms sounds a little more believable. When you can just about watch a spot on the variator spin without loosing that spot , how is it still spinning at 1300 rpms ? 500 seems more accurate. Can some of these TACHS be reading the rpms different ? Both are gy6 157qmj engines , so how can one call for 750 idle rpms and another call for 1700 idle rpms ? I think its worth investigating.

I've done a little research and I saw where some scoots have a lower idle rpm. However I can tell that your scoot is not ilding that low. Im going to say the tach on your scoot is set up different then most. The problem with that is , there is no way the tach is correct. I'm going to make a three about TACHS to see if anyone has any answers.

Right off the bat I can tell your rpms are not correct. I can hear the engine when the idle drops below 1000 , and it is not idling that low. I'll watch more and get back to you. It sounds like your rpms are about 1000 rpms off. I can get mine to idle around 1500 , even as low as 1300 at times , but I usually keep it around 1700. What does it say on your tach ? Mine has x1000 . I'm sure yours is the same . your tach redlines the same as mine so it just must be off. |

Same here , I don't watch either. I used to watch the Simpsons back in the day , but not in the past 15 years.

I checked on ebay and all of them looked slightly different than mine. I figured buying the exact part would avoid any fitment issues. I checked the tracking number and now its showing through UPS as a shipping label created but nothing has been shipped yet. I guess ill have to wait a damn month before this thing comes in. Have u checked " partsforscooters.com" I've ordered from them a few times. |

the clutch is being kind of chattery at the moment as if it's glazed, but I'd say maybe 2500? i checked the bowl yesterday after it died and refused to start again. i have a manual gas cut off now so i dont think i can check it anymore because the bowl will fill up immediately. i was thinking the cam would have an effect on jetting not idle rpm, like since more air is being pulled in more gas would be required. in regard to idle speed, I'd think low rpm would be worse with a bigger cam. can i upload a video here? i can show you the low idling and maybe my tach is just off i going to check the plug to see what color it is, I'll make a short video and try to put it on youtube for you to see Yes , after downloading a video to YouTube , copy and paste the address here. Your right about the manual shutoff . I have one also. The only thing you can do if you suspect the float is to adjust it and give it a shot. |

The only ones prepping the track are the ones who are racing against the 405. They even laughed at them for it. They were suppose to be street racing but the Chicago guys were spraying the whole rd , lol. Turbo cars are the future. The nitro cars are running all out and still cannot keep up with most of the turbos. It would be nice to see a show with true illegal street racing but that's impossible in these times. Everyone would be in jail and have their cars impounded . as it is , the show is perfect for TV and def real enough so it can still be called street racing. Before the show , I'm sure it was all done illegally and on unauthorized streets. The only way the cities allow it , is because they are making money off of it also. Jut like shooting a movie. The cities make a ton of cash. When it comes down to it, the racing is real , the cars are " mostly street legal" , and its fun to watch.
Did you see the farm truck , lol. They actually go around and race on the street illegally . but there is no chance of having more then one or two races before the cops come.

I've never seen a tensioner with an o ring . the only gasket is between the tensioner assembly and the engine case. The center bolt just screws in. Mine is stripped and it never leaked once. I just barely tighten it down . I've even had the center bolt out before while the engine was idling and it doesn't blow any oil. Left mine out after the first BBK, thinking (like you) it was just to keep dust out. Gushed oil. Put a bolt in and it still weeped oil. Threw some gasket cement under the bolt head and it stopped leaking. I never rode with it out, just at idle. |
