valve adjustment , recheck , did you tighten the intake manafold ? how long since it ran last . Could the pilot jet be restricted . Check the enrichener , read the plug . John Plug wet like possible flooding. Maybe Enricher? |

So top end rebuilt. Got it started right up. Problem is that now when it gets warmed up it starts spitting and sputtering then wants to die. As soon as it is all cooled off it will start up and run until it is warm and the same thing happens. Oh and once it dies after it is warm it will not start again. CDI is not warm at all. I thought that it might be getting hot and cutting out.

You have to check the Voltage of the Yellow wires with the Scooter Running. You should get over 60 volts between each set of yellow wires. The Yellow wires come from the Stator in the motor. Once you find out that the Stator is putting out enough voltage then check the other side for your voltages.
By chance did you do a good PDI when you got the scooter?
I had an issue with mine my scooter would shut off when I turned left. come to find out the wire harness was zipped tied tight against the steering column bearing housing with a very sharp edge that ended up cutting the insulation on the wires causing a short and killing the scooter

Oil retention in the crosshatching created by the honing. At least that is what it says in this article. .aa1car.com/library/honing98.htm" rel="nofollow" target="_blank"> .aa1car.com/library/honing98.htmEngine Cylinder Bore Honing Copyright AA1Car When an engine is rebuilt, the cylinders usually need attention. Wear tends to create taper in the upper part of the cylinder that can reduce ring sealing and increase blowby and oil consumption if not removed. The cylinder may also be out of round, scored or have other damage that requires correcting before a new set of rings will seal properly. The main objective when refinishing the cylinders is to make the walls as straight as possible (no taper), the bores as round as possible (minimal distortion, which is especially important with low tension rings), to have the right amount of crosshatch for good oil retention and ring support, and to produce a surface finish that meets the requirements of the rings. This is done by boring and/or honing the cylinders in one or several steps with various types of abrasives (vitrified or diamond). After honing, the cylinders need to be cleaned remove residual abrasive and metallic debris that is left in the bores. Washing and scrubbing with warm soapy water will remove most of the unwanted material. But washing alone does not loosen or remove surface "swarf" such as torn or folded metal that can wear rings and delay ring seating. The only way to get rid of this material and smooth the bores is to "polish" the bores after honing with some type of flexible abrasive brush. Bob that is my point for the question. This is what to do to your Cylinder if you are just replacing Piston and Rings. But we are talking a new cylinder that has never been run. |

there is a small access panel under the seat that you can get to the plug if you have VERY small hands and arms. I have always found it is just easier to take the Air box off to get to the plug to replace it.

Feed your 401k not FICA Did I catch you in time ? John Yes it is not together. but I do have to ask. I have looked at a lot of different material. I have never see anything that said HONE a brand new cylinder to get the rings to wear in properly. I was always under the impression with a brand new cylinder, piston and Rings that they would wear in together. So what is the purpose of honing a new cylinder? I know when I rebuild RC motors if I would be to do that to a new cylinder it would destroy the cylinder. The cylinder and piston in an Nito RC motor have to be brought up to temp and broke in to ensure that the piston and Cylinder wear in together to keep pinch and compression. |

Making out just fine. Most likely will not be back on finishing up putting motor back together until this next weekend. Looking like it will be a 60 plus hour week again at work. So with an hour drive each way to and from work I will be doing good to go home catch a few hours of sleep before I have to be back to work... boy life is good huh?  |

Yeah Big and Little cylinder was only 69mm with 17mm wrist pin. What I got from Scrappy was 70mm just like the one that was on my scooter only the wrist pin was 18mm like you said. I did not want to go down in size so so I opted to go find a 70mm piston with 17mm wrist pin so I could use the cylinder that scrappy sent me. I should be going soon.
I was working on getting it together today but I think I messed up the oil ring as I think the ends ended up over lapping a tiny big and looks like I may have boogered it up with the bottom of cylinder staring to slide it on. I have more around since having like 3 70mm pistons now. LOL
I had taken half day vacation today to put it together but of course I was elbow deep in oil when I get a call from work so I had to fire up my Work Laptop VPN in and Remote my computer at work and help get one of my projects out the door today. So maybe next weekend. Going out of town this weekend so will not get any time to get it going. :-(

See Terri.
There is your problem. You are flat out saying that NO ONE should ask for any help of any kind if you are charging someone to do a job.
I work with Civil 3d And I have yet to find anyone that KNOW Every single thing there is to know about all of the features of it. So from what you are saying that I should never go and ask anyone a question without paying for it.
You are right you have your right to your Opinion of the situation.
I guess in your profession you Must be PERFECT then. You must never have to ask anyone for any help at your job? If that is the case then you are 100% correct. Other wise what you are getting paid since you have someone paying for your service you best never ask for FREE advice from anyone.

I would have to say Terri I think your being a bit too harsh. I have read this a couple of times and stayed out of the conversation. Basically from what you are telling me that I could never ask for free information because I am charging someone to do work for them.
So what I am getting at as I am a Professional CADD designer and we charge are clients to do a job for them. Now If I have a question about how to smooth in an intersection with another intersection on a road that is on a slope to get my ditch lines to flow correctly. You are saying that I should not go to a free forum discussion group to get an answer. I should pay someone to help me answer the question because we are getting PAID to do this design work for the CLIENT.

Well wonders never cease to amaze me. I had dropped an email to scrappy late last week just nice note FYI to let them know that they might want to post sizes of the piston and wrist pins on the Linhai top end rebuild kits. I got the kit almost 3 months ago so I was not expecting anything to come of it other than maybe help someone else down the road. They emailed me back and seems that that Actual LINHAI like my dads and the Yamahas since Linhai makes the motors for them use the 18mm wrist pin and that ended up being the kits he got. Well They got in new batch of 70mm pistions with 17mm wrist pins and has sent me one for the kit I ordered. So really since I ordered this kit so long ago I feel Scrappy is going way out of their way to make this right. Chalk one up for scrappy their customer service is coming up. :  |

Well the new Piston was here when I got home today. Got out the Caliper measured everything. ALL is good. Put it in the cylindar checked out good there made sure wrist pin fit and no slop. Now If I can get enough free time this week to get it all put together I may have a decent running scooter.. Work is nuts right now I could work 24 hours a day if I wanted to. So the last thing I want to do after a long day in the office is go out to the garage and work. Im pooped bout time for bed.
