The new motor is complete. It has a TB108 Stage 3 kit, TB manual clutch, and an AHP 4 speed transmission.
The install was pretty straight forward, but there’s several things worth mentioning…
These screws are very tough to get out so if you don’t have access to an impact screwdriver, you can use a screw driver bit and a wrench. =)
I drilled the existing hole from the outside of the case and then enlarged it with a 3/8 bit to fit the neutral contact switch.
Here are the parts needed to add the neutral switch. There are two different models. The self contained unit 35750-969-000 comes with a sleeved wire with connector pre installed and is enclosed in it’s own case. The 3 parts bags below this one is more common and is what I used on this motor.
I forgot to include the neutral wire grommet. That part number is 32981-035-000
Here is the neutral switch installed.
After I removed the high volume oil pump and split the cases, this little guy fell out of the hole. Remember to check for that and if it falls out, put it back in. =)
Provisions made for the high volume oil pump.
AHP 4 speed transmission, honda kick starter shaft, and TB 51mm crank installed…
Ready for the cylinder…
And, just for fun, here’s what the star looks like as you shift through the gears. =)
