3 wheeled scoots are defective in design. 1. the rear wheel is missing. The weight of it acts like a vibration damper. Without it the scooter vibrates like crazy. Add a hack 100cc oversize to a stock 50 and you are asking for a major vibration monkey. Not to mention the engine will blow up sooner than later. Don't waste money on a 50cc trike. Buy a real one. Or sit on one and have you picture taken.  Have you ridden a 50cc trike? If not don't tell people to waste money on one. I love mine. Whats a real one by your definition. I own a 300 also. Is that real enough for ya? I have had a "100cc over-sized engine in mine and it didn't vibrate any more than any other engine. I stated in an earlier post that I ride my 50 to the limit. I have a race course that I run it on. ( I will post a video when I get a camera mounted) I have ran these little engines past 9krpm and 50+mph haven't blown an engine yet. I Have tried to blow an engine, Just to find out what it will take. Its all fun for me, maybe not every one else though. I'm not normal though. I love to push things to the limit to see what it takes to break. Then I fix them and do it again. It is not the design of the trikes that make them vibrate more it is the design of the motor mounts.

You are welcome. I forgot to mention, the speedometer is very accurate if calibrated properly. You input the number of magnets. (the more magnets you use the more accurate it will be) Then you measure the diameter of the tire in mm and input that measurement. You can mark the tire and the floor roll it one full turn then mark the floor again and measure. or you can run a piece of string around the tire and measure it. I used the roll method and only 3 magnets.

The tach can be hooked up two different ways. You can plug it into the pick up sensor or just wrap the pick up wire around the plug wire, like a tint tach. It can also be set for the number of cylinders.

Yes it has a magnetic pick up sensor. It came with 6 magnets that you place in the brake rotor bolts You can use 1,3, or 6 magnets. You can also purchase different magnet mounts and bolts with magnets in them . This is how I mounted the speed sensor.  Roy |

Yes, it is easy to read at night. It is back lit by a blue indigo light. You can see the light in a couple of the photo's. The flash from the camera blocked out the light in the rest, that is why it looks like a plain LCD

It would not be to hard to install an oil cooler. I would not want to use the stock oil pump though, it may not move enough oil to be useful. I would want to add an electric pump. The electrical system on these little engines is barely enough. I already am pushing it to the limit with the electric fuel pump for the efi. I could be done though with a low current oil pump. This gauge has both water temp and oil temp, but will only display one at a time. A push of the button will change it though.It does have a warning light that comes on when the temp reaches a preset temp. I can also set the temp. I purchased a spark plug temp sensor ring and use the water temp to read head temp. The speedometer can be read in mph or kph. It also has a tach. It is a full dash panel with blinkers , high beam, ect. I cant remember what all the lights are for and will have to find the manual. I installed this when I bought it in 2010. I dont have all the features hooked up, But the large light on the top left is the temp warning light. I came with a 7/8" handle bar mount, But I don't have any handle bar space. So I made a custom mount out of a 4" angle bracket.      Roy |

Ya, that probably is a good deal. Mine came from the factory with a secret 72cc engine installed. I paid $1700 for it in 2010. Put one of these trikes through a hard corner to fast and you will be leaning.  I have had my mojo on two wheels several times. I ride it to the limit though. Roy |

I have decided on a different position for the sensor. It will not be in the oil flow, but it is not on the bottom of the engine. It is a bit high up but it is lower than the bottom of the dipstick.  Roy |

Why not? the meter has the feature, might as well use it.

My koso digital meter has an oil temp feature. I am trying to figure out the best place to drill and tap the case to install the sensor. I think this would be a good spot. This is the thickest part of the case and it is close to the oil filter screen. It will be in the flow of oil to the pump. What do you all think?   Roy |

i heard of a guy that rebuilt an engine he didn't know where the rings went so he left them out . John Wow! I wonder if he ever got it to run? ;D Roy |

What do you use to edit your photos? Adding text, pointer arrows, circles, ect.

This is how I align the ring gaps.
With the intake at 12 o-clock.
1st ring gap at 2 o-clock.
2nd ring gap at 10 o-clock.
Thin top oil ring gap at 5 o-clock.
middle wavy oil ring gap at 6 o-clock.
thin bottom oil ring gap at 7 o-clock.

Did you check the ring end gap? 1st ring gap should be.007 inches the 2nd ring gap should be .009 inches

I have an A9 cam that I didn't use because the chain was to tight, the cam sprocket measures 66.54mm at the peaks and 60.21mm in the valleys. A stock cam I have measures 66.38mm at the peaks and 59.95mm in the valleys.
