In Thailand most people who have a 125 to 200cc race bike, are removing the electronic fuel injection (EFI) because it is difficult to program (adjust) and the extra weight vs benefits are most of the time not in favor of a EFI. |

I currently use a GL145 carb which is 30 years old and it's bore small at 22x29. The cam is big, 10 mm valve lift and is 270 degrees at 1 mm. It is still a 2 valve motor. It is producing about 19 hp at the back wheel and runs to 13000. I do have problem however, the bike starts and runs well, however once warm, if I rev the motor, it will not return to idle. It will stay at 5000 rpm. If I am standing still and I slip the clutch and force the motor down to idle, it will then happily idle at 1800 until I blip the throttle again |

We had in the past contact with an American company that was specialized in carburetor to fuel-injection conversions. The website is http://www.ecotrons.com/ . |

I looked at that page several days ago but was not too impressed. They have motors running but I would like to see a before and after dyno graph with real results. The fuel timing sync is picked up from the spark trigger coil. That does not sound good to me. It is nearly 360 degrees out of phase with the fuel squirt. |

Thanks I was looking at the Megasquirt but hadn't come across the Microsquirt as yet. Much better size for a bike. Once I find the other hardware I'll probably get a Micro. |

The Suzuki FXR 150 is never officially sold in Thailand, but the good news is that the Suzuki Raider 150R uses the same engine. Actually the engine of the Suzuki FXR 150 was also manufactured in Thailand. |
