Hey guys i have good news finaly!  Heres the list of good news: 1 - Change the cilinder, piston+rings, cilinder head: After this modification i noted more suction on spark plug hole even with me turn the crankshaft manualy and about the compression i cannot place mi finger on sparkplug hole even with me turn the crankshaft manualy too. 2 - Change the gaskets of cilinder and cilinder head for a new one: No compression leaks in process with the engine running... 3 - After the change the noisy engine works more smooth with a suported noise, nice humm!  4 - On the next monday i will change the exaust for the one from Honda Biz 100cc see the picture  5 - I rework the plastic fairing and paint too. For mending cracked parts I used super glue and other bits of fairing itself, to remake the original socket screws I used plastic bushings involved with epox glue and it seemed good to me. 6 - I change the wires and i noted bit diference on charging system with the lamps on and the engine running do not decrease RMP like the another wires. 7 - I put back the turn signal lamps, since the bike do not have ones. 8 - the bake works but i have not reassembled it yet. Now here the bad news:  1 - The bendix is broken soo only kick start my friend... 2 - I will change the cvt belt but i not find here in my country again i´ll have to mine a lot to find. 3 - The tires specifiing in service manual 110/70 12 for front weel and 120/70 12 for rear weel i cannot find the front weel tire and i dont know if can put same tire on front. 4 - The speedometer cable is broken and i dont know how to change. 5 - The rear break not working too is very hard and almost no brakes the bike. 6 - The carb is another problem yet, i do not want to mess this part yet. So guys this is it for today! and thanks for al the help give to me. Sabo. |

yes if it says that in the manual then go with that. You want it to smoke but not to blind someone behind you  Ok at the moment the bike is not runing because of parts i wait to reach to put on there also im working on painting. She dont work well yet because of lost performance when she start from neutral to runing but when she moves is very faster, this problem to me is a mistery yet (the compression is ok), i order a rectified cilinder kit and i hope this is the problem, but i dont know what can be.

If it says 30:1 then mix it 30:1 no more than 35:1. Alleyoop So this is the correct ratio for premix gas/oil? Great! Sabo. |

Hello guys I was reading the service manual of the bike and saw some information that I did not understand about the oil pump, the picture says it used a mixture of 30:1 the engine then that would be the correct ratio for this engine?  Sabo. |

The vacuum lines are ok! But i think to replace all the hoses because of wear...I bought a new kit of cylinder, piston and piston rings rectified because here in Brazil i dont find any new, they are arrive until the weekend maybe a new kit will make some diference on performance now i have the new wires and working on the lamps and the renovation and painting of the careen of bike, i find a new problem about the speedometer cable he dont working and I was measuring the speed with a cellphone application, but this is minor problem now.

I know this isn't your bike but this illustrates vacuum lines:
They run off of the intake manifold and run to valves and diaphragms. There is no gas or oil in them, they simply provide vacuum. If one isn't connected they cause a massive air leak into the intake system and ruin performance. Rich Ok i will check this, i think of replace all the hoses...the hose from fuel tank is very bent too but i see the fuel in gas filter flowing smoothly no bubbles or something else. Sabo. |

You don't have any vacuum lines running unplugged or unconnected do you? The vacuum system must be sealed or it will ruin the bike's performance. Rich I do not know if I speak nonsense, but if there were problems there should be oil or fuel leaks anywhere? Sabo. |

Hey people i make more changes on bike now i change the wires from another scrapped bike the wires are intact i replace and noticed a slight improvement when I turn it on the lights are more strong, the charge system works beter too but I have not walked the bike to see how it is performing, because I am hoping to get more pieces, perhaps I walk on it next weekend, the oil pump, although not connected at all, works! She was with the hose connected to the intake manifold and sucking air from the other end would the oil reservoir, ie sending more air into the engine after passing carb, maybe it works better when I reassemble it. About this to my wife, she liked the idea of having a bike but she knows that the bike still does not runing well.

Oil in the exhaust would be understandable if the mixture was a little heavy on oil. But it could also be blow by from the rings. I still think the compression is the issue. That's just my opinion and two strokes are not my forte. Rich Ok i do more tests and have compression like aley said i put my finger on plug hole and crank the bike and my finger will forced to blow out from there about the oil i have my dubts about the carb when i take out the spark plug and see it its clean no dirt or carbon like a good spark but after i stop the bike for a time, 3 days to exact, i turn on, and the motor works poorly and the bike not move from his place i have to keep all the throtle open until she recover power and finaly move but after i run for a time the problem disapear again and all the times i crank the motor she works and move like normal i think all the problems have connection whit the carb and i cannot place the original in place i have to make something adaptation from anoter carb.

NO YOU WANT MORE GAS LESS OIL. The Pipe from another bike you can try it. If it is a straight through pipe it will not work to good. 2 Strokes need some back pressure more than 4 stroke motors. Alleyoop Ok i understood! Yes sir! Rise the gas, but make the mix 32:1 for 5L of gas will be 142ml of oil "rise" the oil mix but if say to low the oil i will obey what did you think 100ml or 90ml oil? About the pipe i will try to make a test. Thanks. Sabo. |

I would go down to 35.1 on he oil mix that plug is fouled with oil and running on the rich side so also adjust your carb to lean it out a little. Now without a compression tool to check if it has OK compression stick your finger in the hole HOLD THE THROTTLE WIDE OPEN and CRANK THE MOTOR OVER. IF it LIFTS your finger off the hold it has OK COMPRESSION if it DOES NOT LIFT your finger off the HOLE then you have LOW COMPRESSION and no power. Alleyoop Lower the premix whit minus gas and more oil? I dont know if it will work! But i have to empty fuel tank frist. Tomorow i will make the test whit compression you said and post the results. And about the exhaust pipe from another bike i can put whitout problem? Sabo. |

Here the loaner tool programs at AutoZone, Advance Auto, etc.. generally require you to pay full price for the tool up front. You use it and bring it back with the receipt they should give you and then you get a full refund if the tool is still in good shape. Can't just grab a tool off the shelf and do this, you have to talk to them and tell them you want a loaner tool. No idea what's available or what stores are where you are though. If you can blow through your current exhaust pretty easily and feel air coming out the other end, it's probably fine. Old pipes can be cleaned out with a caustic soda, but don't use that on aluminum. If you Google "decoking" or "de-coking" and two-stroke or 2T pipe/exhaust you should see all sorts of info on cleaning exhausts out. Ok i will try to talk with the guy from the bike parts shop and see whats happens, and about the exhaust give me by my friend i can realy put on bike like Bashan said? I make a search on google and see some changes of exhaust can cause a poorly performance of bike. A guy from another bike fix shop said the problem is not the compression because if was the bike never reach till the max velocity she only delay the reach till the max and when i take a ramp on full throtle she going like a charm and no lost power. I dont know what can be and my bet is the carb again if the guy is correct. Sabo. |

Yeah, go ahead and try the exhaust pipe, I don't think it can hurt anything. What can hurt them is running WITHOUT one. You may be correct, the exhaust may be clogged. I agree with Brent, I still think you need to check the compression. The finger thing just doesn't cut it. Around here you can go to an Auto Zone or other parts store and they will loan you equipment like that. They don't do that in Brazil? Even so, you can get a compression test kit for under $50.00 at Harbor Freight. It would be worth it IMO. Rich I also want to test compression but here in brazil i dont know how this works and to be honest i dont think the guys from bike parts shop will loan to me, my only exit is to buy one here, also i bought a flattened cylinder with the piston and rings this take time to arrive here something about 2 weeks on this meantime i will make some cleaning and modifications, like i sayd before the bike works but in ramps is ridiculous to try to accelerate on the other side on clean and plain route she runs like a charm. Thanks for reply. Sabo. |
