Sprocket did quite a bit of research on the GY6. He was going to write a book on them but I don't think that ever came to fruition. One thing he contended is they are not clones of a Honda engine. I don't know on this. Second, he said they were designed to run for extended stretches at 80% throttle. I'd say this was accurate based on what I've read and looked at on the oil delivery system. Also, these things run hot! 240 is not unusual. It sounds like you've had them apart more than once. Did you ever look at the oil pump and say "what?" It not only is supposed to provide lubrication but help control the temperature. The oil cascading inside the head and cylinder is supposed to diffuse heat. I don't think it takes a lot to exceed both of those demands. Don't get me wrong, I've been guilty of "gee, this sounds really strong at WOT, I LIKE it!" They are not designed for that. The QMK got an oil cooler because of the heat control demands from a larger displacement engine. Another thing is how much extra performance can we expect to wring out of these engines before they fail? Were they designed to handle tacking on enhancement part after part? IMO...no. Is there a less expensive way to cool the oil. The oil coolers I've seen run $100-200. That's a fourth of a new bike. |

Which? .005 both or .003 intake and .004 exhaust? |

Who threw a rod at 830 miles? Nobody I know. If they did they must have forgotten to fill the oil sump. These aren't two strokes.
I had a Kawasaki with 125,000 miles and no internal problems whatsoever. Your point?I threw my rod bearing at 830 miles. I was running Amsoil 10w40 motorcycle oil. Im a nazi about oil and maintenance. I believe I ran it too long at WOT. Won't do that again. (2008 Lifan 150t-6) |

My owners manual says to set both valves at .005, but that seems a little noisy. If seen recommendations for .004 intake and .003 exhaust. What say you?

i replaced the stock rollers (white) with 14 ounce sliders in a koso performance variation. Would this cause the decrease in accelerationI'm experiencing?heavier That's 14 gram sliders and yes, that's the cause. You probably had 13 gram rollers which fly out easier than a 14 gram slider. I think it was Alley who said that a slider acts like a one gram heavier roller, but I forget. (eg. a 14 gram slider is like a 15 gram roller) Kinda yes. What happens is that a slider reacts quicker than a roller, so if you go up one gram on your slider, in theory, you'll retain the acceleration characteristics of the 1 gram lighter roller while gaining the higher top end of the heavier weight. (Providing your scooter has enough engine to push a heavier weight.) Thanks for the 'splanation Matt. |

Without the upgraded piston kit the 14 gram sliders are just too much. Reinstalling the rollers tonight. |

bought the upgrade Variator and sliders for the piston kit (installed). Bought the stock replacement piston and rings and got'r all back together. Now I'm chugging (lugging) cause my sliders are too light or too heavy. I'm not sure which. i replaced the stock rollers (white) with 14 ounce sliders in a koso performance variation.

Just sharing. I like the the more modern white light as opposed to the warm white of the incandescents. Not sure I like the blue affect on the headlights, but they are very bright when looking straight on. Tail lamp is much brighter than stock. I also lined the license plate light housing with aluminum foil. |

Yep you need to get a LED FLASHER to equalize the voltage going to them. You can find them at any auto parts store. Look at your flasher and see how many connectors it has 2 or 3 and get one with the same number of connectors. As you found out the current flasher will handle the two in the rear but not the ones in the front. Alleyoop Thank's Alleyoop. Are you saying I need a second LED flasher or a new flasher to handle all four LED's? |

Should the valve be snug or loose against the gauge when adjusting the valves?

Thanks Bashan. That makes sense. Looking forward to Alley's response for a possible solution. I hear you on the cost of bulbs, but I got these fairly inexpensive. $4.33 w/$1.99 shipping on eBay.

Thanks Bashan. I appreciate the welcome. I've had my scoot since November. Already learning things the hard way. Thought I was doing everything right, oil changes (synthetic), gear oil, spark plug etc. Then at 830 miles I lost my rod's needle bearings.  ? bought a 155cc piston kit online. Oops, my 1(P)57QMJ wasn't compatible (fortunate to return). I had already bought the upgrade Variator and sliders for the piston kit (installed). Bought the stock replacement piston and rings and got'r all back together. Now I'm chugging cause my sliders are too light or too heavy. I'm not sure which. I got all kinds of electrical probs. Lost my stator (8 pole). New coil and CDI. My most recent issue is my front turn signal will not take the LED replacement I installed. Rear turn signals took the LED's just fine? ? any thoughts? I posted about it in the 150cc section of this board. I'm looking forward to learning from all you veterans of scooter wars. |

Replaced my rear bulb blinkers with no issues. When I replaced the front blinkers with same bulbs this is what happens.
yes, I did check to see that the new LED works in the rear sockets.

? And again at 2033mi.
