Hey guys,
I'm finally getting started on my motorized bike project.
Bicycle: a GT Aggressor (I'm sooo aggressive... :???: )
Motor: I'm using a Tanaka PF-4000 that I totally redid,
making about double the power of stock.
(pipe, lowered cylinder, porting, modding and stuffing of cases, bigger carb,
no rev limiter mod) Est about 4 HP.
I'll post picts of the mods if anyone wants to do them.
It's pretty easy to do.
Drive components: I'm using the rear end of a Boxer FS-1 motorized scooter
(spindle drive, with gas tank mounted on the opposite side
as the clutch assembly)
This is almost going to be a bolt on job to my bike.
I just have to mount the rear assembly to the seat post
(I have the remnants of one of those "trail a bikes"
so the linkage is almost made)
The original spindle on the scooter was a .850
and it pulled hard with it. I just took some skateboard wheels, and drilled them out to fit on the old spindle.
I'm going to use set screws in the beginning , and epoxy them on to the shaft once I'm satisfied with their size and gripping ability.
I'm pretty psyched about the project, I figure it will be ready to run by the end of the week.
My only real question is how large of a spindle I should do.
The wheels right now are about 1.6 inches.
I can shave them down easily with a grinder,
so I'll try it like it is first.
What size spindles do most of you folks use?
I had a feeling that around 1.25+ would be fine... but I'll
try the large size first.
I'm looking for speeds about 35ish
Here's a shot of the rear without motor or gas tank....
